19th July 2022 - AIR-IQ Spectral Search

AIR-IQ Spectral Search

Protea’s patented algorithm for spectral identification is now available within our PAS platform. The AIR-IQ plug-in offers a unique and powerful searching tool to enable users of our spectroscopic instrumentation (FTIR and Mass Spectrometer) to identify unknown gases in their sample, being able to then add to the analysis method quickly and easily.

AIR-IQ Spectral Search

Built upon decades of experience of analysing complex gas matrices from FTIR emissions and process data, AIR-IQ offers features such as:

  • Library management of qualitative and quantitative spectra
  • Spectral file recognition: auto-read gas names, temperatures, pressures and pathlength - makes adding new calibration references quicker
  • Spectral search window masking and pre-processing steps, including water subtraction
  • Subtraction of identified gases and re-analysis: iterative approach to qualifying all gases in sample spectrum means ALL unknows can be identified one after the other.
  • Identified gases are seamlessly added into the current analysis method. This can be done as “ interference only”, meaning re-calibration is not required and existing methods can be corrected quickly without generating new references.

Please contact Protea for more information on AIR-IQ, if you are a new or existing customer.

12th May 2022 - Ethylene Oxide Monitoring

The atmosFIR FTIR gas monitoring system from Protea has been successfully installed measuring low levels of Ethylene Oxide emissions from sterilisation facility. Working together with the supplier of the emissions purification technology, Protea’s FTIR gas analyser can monitor the very low emissions produced post-purification to confirm emissions are below the stringent limit values and that the abatement process is working effectively. A measurement range of 0 – 5ppm of Ethylene Oxide was delivered, with a lower detectable limit of 20ppb.

Ethylene Oxide Monitoring Ethylene Oxide Monitoring

The atmosFIR system delivered is the same configuration as our MCERTS approved emissions system for combustion incineration processes, but with a lower operating sample temperature. The benefit of FTIR as a solution is, not only that it can deliver the measurement accuracy for Ethylene Oxide itself, but FTIR allows for the addition of other gases or interference correction should there be any other gases within the sterilisation and abatement process in the future.

1st April 2022 - CCS Carbon Capture and Storage

Protea’s atmosFIR FTIR gas analyser has proven a valuable tool in research into the effective storage of Carbon Dioxide (CO2) in the North Sea. Carbon Capture and Storage (CCS) is a key technology to reduce carbon dioxide (CO2) emissions from industrial processes in a feasible, substantial, and timely manner. For geological CO2 storage to be safe and reliable, robust strategies for CO2 leakage detection, quantification and management are crucial.

CCS Carbon Capture and Storage

The STEMM-CCS (Strategies for Environmental Monitoring of Marine Carbon Capture and Storage) project aimed to provide techniques and understanding to enable and inform cost-effective monitoring of CCS sites in the marine environment. A controlled CO2 release experiment was carried out in the central North Sea, designed to mimic an unintended emission of CO2 from a subsurface CO2 storage site to the seafloor.

CCS Carbon Capture and Storage

Protea’s model atmosFIR FTIR gas analyser was used on board the RRS James Cook to measure the molar fractions of CO2, SF6, C3F8 and CH4 in the discrete gas samples collected during the release experiment. The FTIR was equipped with a custom-made sample injection system allowing reference gases to be injected. Find out more at

3rd November 2021 - Lowest NO and NO2 MCERTS emissions analyser

Protea’s atmosFIR FTIR emissions analyser now has the lowest certified NO and NO2 range of any FTIR analyser and is one of the lowest range NO/NO2 instruments of any technology on the market. With global emissions limiters becoming lower, measurement technology needs to be suitable for the lower ELVs. atmosFIR can offer a NO range of 0-80mg/m3 and NO2 range of 0-50mg/m3. Older FTIR technology limited by resolution often achieve only 0-200mg/m3 range for NO2 for example.

Lowest NO and NO2 MCERTS emissions analyser

This increases the potential for using the atmosFIR (available in portable as well as CEM versions) to low-NOx emissions plant emissions testing. Added to this the power of FTIR in measuring hundreds of gases with one instrument, atmosFIR is the proven future-proof technology for emissions monitoring.

Protea can also announce our NH3 (ammonia) MCERTS range has been improve to 0-10mg/m3.

11th October 2021 - Differences between CEN/TS 17337:2019 and TGN M22 for Portable FTIR Emissions Testing

Protea and the National Physical Laboratory (NPL) have recently completed a Measurement 4 Recovery (M4R) project to produce an Industry Transition Document (ITD) that concisely lays out the changes required of stack testing organisations transitioning from TGN M22 to CEN/TS 17337.

Differences between CEN/TS 17337:2019 and TGN M22 for Portable FTIR Emissions Testing

Currently, UK stack emissions laboratories are moving from following TGN M22 to CEN/TS 17337 for reporting of industrial emission measurements using portable FTIR gas analysers, such as the Protea atmosFIR. This change is not without some complexities. In order to implement the new measurement method, the laboratory has to know what changes in sampling apparatus are required, for example, and how the new standard requires them to process, QA/QC check and report results from their FTIR. Protea’s FTIR analysers and software are fully compliant with the requirements of the new standard.

As one of the leading manufacturers of FTIR for stack testing organisations Protea have always provided significant support to our user base. This document benefits not only the customers we support, but also many other stakeholders in the emissions community, from laboratory assessors, to regulators and plant operators who are receiving the reported data from portable FTIR analysers.

5th November 2020 - Flame Ionisation Detector (FID) Total VOC Launched

Protea’s Flame Ionisation Detector (FID) analysers allow for Total VOC analysis from a range of emissions, process, exhaust and ambient air applications. Protea’s Flame Ionisation Detector (FID) analysers are used to give quick, accurate measurement of Total VOC concentration in a range of applications such as emissions and process control and offer MCERTS EN 15267-3 QAL1 certification. Find out more at

Protea’s Flame Ionisation Detector

Within the FID analyser chamber is a Hydrogen (H2) flame burning in an electrical field. The flame is fed by high purity fuel gas (atmosFID can use H2 gas or a H2/He mix) and a hydrocarbon (HC)-free combustion air. The sample gas to be analyzed is then also fed into this flame. The hydrocarbons within the sample gas are "cracked" in the flame and the resulting HC fragments are then ionized. An ion current in the order of 10-14A is generated in the electric field; this electric current is related to a DC amplifier and gives the detection of the HC content.

The measuring method requires that the measuring signal is proportional to the number of non-oxidized carbon atoms in the sample gas. Carbon atoms that are pre-oxidized are only partially measured.

2nd September 2020 - Introducing BetaCap Capillary Gas Divider

Capillary technology offers an improvement in uncertainty of measurement of a gas dilution system over other technologies. The BetaCAP range of blenders offered by Protea has a set number of highly accurate capillaries – 30 or 60 as standard. The unit “switches” in the most suitable capillaries to generate the desired gas concentration, with fine-tuning of the gas delivery being made by pressure compensation.

Introducing BetaCap Capillary Gas Divider

The relative measuring uncertainty is low with this type of blender technology, as it is a function of the measured value of each capillary that is used not the instrument range, as is the case with sonic nozzle or MFC blenders. Blenders are offered in laboratory or field-ready packages, as well 19” rack configurations for installing alongside gas analysis equipment. Find out more at

3rd August 2020 - Introducing the atmosCAL MFC Gas Divider

The accurate calibration of gas analysers is critical, during factory build, routine service but also for on-going field assessment of analyser performance. Protea has developed the atmosCAL Gas Blender to enable dilution of high concentration gas cylinders over lower concentration ranges, in order to calibrate gas analysers - allowing characteristics such as absolute reading, repeatability, reproducibility, linearity and response time to be tested on analysers.

Introducing The atmosCAL MFC Gas Divider

Using multiple Mass Flow Controller (MFC) technology, generating required gas concentration is as simple as typing into the touchscreen the desired concentration and choosing the flow rate. MFC technology operates on the principle of thermal mass, and different gases require compensation. The atmosCAL embedded software is pre-loaded with a range of compensation factors so the majority of gases can be used with the atmosCAL without adjustment. Find out more at

1st March 2020 - Well-prepared Operators Have Ensured a Calm Switch to the IMO 2020 Sulphur Cap

In the past few years, the clarion call has been to delay the introduction of 0.5% low sulphur fuels as the dangers were many: not enough fuel, crew would be hard pressed to understand the changes from one fuel type to another, ships would break down in the middle of the ocean, and so on.

Well-prepared Operators Have Ensured a Calm Switch to the IMO 2020 Sulphur Cap

Quietly, the regulator, the International Maritime Organization (IMO), has maintained its line and finally, when the day of reckoning arrived, the anti-climax was deafening. Not that the introduction of the IMO 2020 sulphur cap has been all plain sailing — far from it. Shortages in some regions and the delays to vessels, of up to three weeks, in Singapore are testament to that.

However, as one bunker expert told Clean Shipping International: "The vessel operators were so well prepared that the transition has been very calm."   Even the major issue in Singapore, which saw Pacific International Lines' ships stranded, was not a failure of the fuel supply, but rather the consequence of attempting to supply a number of fuel types with too few bunkering barges. Or, as the expert suggested, once barges had cleaned their tanks they were reticent to “dirty” them again by filling them with high-sulphur fuel again. While events such as these are unwelcome, they are not the catastrophic events that were sometimes alluded to in some shipping circles.

In fact, the conversation has very swiftly moved on to the greater impact of a faltering global economy, which has seen declines in demand for goods and consequent decline in demand for oil, pushing prices for oil downward with the knock-on effect of seeing the price of bunkers also falling.

Added to the general malaise is the coronavirus issue. This is having the effect of stalling parts of the industry with a number of China’s major cities in lock-down and backlogs of cargo building in ports around the world. This was definitely not on the menu when the IMO served up its sulphur cap regulation.

Cost is not the major issue for the shipping industry, however, but the spread between fuel types is significant, that is the price differential between very low sulphur fuel oil (VLSFO) and 380 heavy fuel oil (HFO).

On 7 January, bunker prices stood at US$401/tonne for HFO and $740 for VLSFO. By 10 January, that convergence had already begun with a spread of $326 between VLSFO and HFO, according to figures from the Sweden-based Marine Bunker Exchange (MABUX).

Today, the MABUX index shows a spread of $200/tonne, but the narrowing of the spread has stalled over the past few days. That is good news for shipowners that fitted exhaust gas cleaning systems (EGCS), which can offer cheaper freight rates to those owners that are still operating on VLSFO.

The spread is key for EGCS users to recoup the capital cost of the equipment used to clean the sulphur from exhaust gases, but the next deadline for the maritime industry is 1 March, when all ships that do not have an EGCS will be precluded from bunkering, or storing, HFO. It will herald the end of an era and, as with the nature of such things, the entry into a great new epoch.

For owners with open loop capabilities on their EGCS, the reports on the use of these scrubbers and the discharge of washwater will also be a key factor. However, the question will arise again at IMO at the next Marine Environment Protection Committee meeting, MEPC 75, which will convene for five days from 30 March.

Even so, Armageddon appears to be a long way off for the maritime sector. Its adaptability to new realities is legendary — and it will be tested to the full over the coming decade.

10th February 2020 - Limiting Engine Power to Reduce CO2 From Existing Ships

As the International Maritime Organization works to reduce greenhouse gas emissions from international shipping, technical measures to limit engine power are among the ideas being considered to reduce carbon dioxide (CO2) from the existing fleet. Engine power limitation (EPL) is a semi-permanent, overridable limit on a ship’s maximum power that could reduce fuel use and CO2 emissions if it reduces the operational speeds of affected vessels.

Limiting Engine Power to Reduce CO2 From Existing Ships

This study models the relationship between varying levels of EPL and CO2 emissions based on 2018 real-world ship operations. The authors find that CO2 reductions are not proportional to engine power reductions because ships are already operated well below their maximum speeds and therefore engine powers. EPL scenarios below 30% provide negligible cuts in CO2 for the 2018 fleet, while a 30% EPL is estimated to reduce CO2 by 2% for container ships and oil tankers, and 3% for bulk carriers. Larger, 50%+ EPL could more meaningfully reduce ship CO2 by 8%–19% depending on ship type and size.

Additionally and importantly, benefits diminish over time if EPL is not required for newer ships due to fleet turnover and growth. As illustrated in the figure below, by 2030, EPLs of 30% or less would reduce fuel use and CO2 emissions by 1% or less, while the maximum 60% EPL scenario would cut emissions by about 6%. By comparing a Base scenario with a High Speed scenario, the authors find that EPLs of 30%+ in 2030 could help lock in the fuel savings of existing slow steaming practices by constraining future speed increases.

3rd January 2020 - Cleaner Air in 2020: 0.5% Sulphur Cap for Ships Enters Into Force Worldwide

From 1 January 2020, the maximum sulphur content of marine fuels is reduced to 0.5% (down from 3.5%) globally – reducing air pollution and protecting health and the environment. Sulphur Oxide (SOx) emissions from ships' combustion engines cause acid rain and generate fine dust that can lead to respiratory and cardiovascular diseases, as well as reduced life expectancy.

Cleaner Air in 2020: 0.5% Sulphur Cap for Ships Enters Into Force Worldwide

Commissioner for Transport Adina Valean said: “Maritime transport is a global business, and reducing its emissions requires global solutions. The entry into force of the global sulphur cap is an important milestone for the entire maritime sector; it will contribute to further reduce emissions of harmful air pollutants, directly benefiting cities and communities around the globe, including important ones on our Southern European shores. It also shows that concerted effort from the EU and the IMO, together with strong commitment from the industry can deliver important benefits to the environment and the health of our citizens.”

Commissioner for the Environment, Oceans and Fisheries Virginijus Sinkevicius added: “The European Green Deal is set to deliver on a zero-pollution ambition for both climate neutrality and a toxic-free environment. This EU ambition protects our citizens' well-being, but also ensures healthy and clean environments, seas and oceans within a carbon-free and sustainable blue economy where all sides jointly engage, including maritime transport. We welcome low sulphur standards globally and in Emission Control Areas so that more EU coastal citizens can breathe clean air.”

EU's low sulphur approach as international example

Since 2012, the EU has taken firm action to reduce the sulphur content of marine fuels through the Sulphur Directive. In 2016, the International Maritime Organization (IMO) maintained 2020 as entry-into-force date of the global 0.5% sulphur cap.

Moreover, in some very fragile ecosystems such as the Baltic Sea and the North Sea – designated as ‘Sulphur Oxides Emissions Control Areas' (SECAs) – the maximum sulphur content has been reduced to 0.10%, already in 2015. Such stricter sulphur limits have more than halved sulphur dioxide concentrations around SECAs, bringing health benefits to people in coastal regions and ports, while the overall economic impacts on the sector remained minimal.

Next steps on sustainability in shipping

Based on the successful implementation of the Emission Control Area (ECA) limits, the introduction of the global sulphur limit is expected to bring similar results. The EU is also actively working in the context of the Barcelona Convention, on the possible future designation by the IMO of ECAs in other EU waters such as in the Mediterranean Sea.

The EU has striven for an active role in tackling maritime emissions more generally, both at home and globally. In 2018, the IMO agreed to reduce greenhouse gas emissions from shipping by at least 50% by 2050. The EU and its Member States played an instrumental role in brokering and securing the deal for the sector, which currently represents 2-3% of global CO2 emissions. Discussions are already ongoing at the IMO to translate this deal into concrete measures.

To tackle plastic pollution within our oceans, the EU adopted new rules on port reception facilities, making sure that waste generated on-board ships or fished at sea is collected and treated in ports.

The EU is also working with the IMO to address concerns regarding discharge waters from after-treatment systems used by ships. The objective is to ensure full sustainability of those systems, possibly by setting stricter and uniform legislative requirements.

In addition, the European Green Deal, presented by the President of the Commission Ursula von der Leyen in December 2019, sets out further action to make shipping more sustainable such as the extension of the European emissions trading to the maritime sector.


Maritime transport has a direct impact on air quality in many European coastal cities. Exhaust gases from ships are a significant source of air pollution, including through sulphur oxide emissions resulting from the burning of fuel oil. Sulphur oxides are harmful to the human respiratory system and make breathing difficult.

Ships traditionally use fuel oils for propulsion, which can have a sulphur content of up to 3.50 %. For comparison, the sulphur content of fuels used in trucks or passenger cars must not exceed 0.001 %. The 2012 Sulphur Directive which was revised in 2016, reduced SOx emissions by setting maximum sulphur content levels for marine fuels and incorporated new standards set by the International Maritime Organisation into EU law both inside regionally protected areas and outside of those.
