Protea Giving A Training Session At EUEC2024 In Dallas

12th February 2024

Protea will be in attendance with one of our distributors Delta Instruments on booth 623 at EUEC2024 located at the Irving Convention Center in Dallas. We will also be providing a “must attend” training session for experts and operators of CEMs. This training session is part of "Track B" which includes EPA policy and procedures for accurate monitoring, reporting, and auditing of emissions pursuant to Part 75 of the Acid Rain Program & Clean Air Interstate Rule. This will be in Room Room 2 (Track B) Wednesday, February 14, 2024 covering CEMS, Emission Testing, Monitoring, Modeling, Remote Sensing. Come and visit the show and speak to one of the Protea team.

Victoria Brewster from Protea who is Product Leader of Spectroscopic Solutions, will be presenting and stated "The generation of electricity from municipal digesters and landfill is of increasing interest, as the biogas can allow for a form of renewable energy. Organosilicon compounds often find their way into land-fill or digester gases as siloxanes. Siloxanes are low-level hazards to the atmosphere in terms of their emissions, however when they are combusted in gas engines the hard silica that is produced is very harsh to the moving parts of the gas engine. Ultimately this increases maintenance cost and gives a lower energy output, making the generation of power less efficient."

Victoria went on to state "With this ever-growing market, the need for analysis of the siloxane content of the biogas pre-generator is important. A land-fill gas plant operator can determine the amount of siloxane removal of the pre-combustion feed gas. This enables a more cost-effective cleaning system to be employed. They can also determine whether an existing clean-up system is operating effectivelyThere is currently no standard method for gaseous siloxane measurement and to date no on-line gas process monitoring system. The usual method of gas analysis has involved the extraction of a sample gas, via bag or cylinder, and analysis off-plant. Sampling losses of siloxanes inevitably occur, as the sample can be adsorbed onto the sample container walls."

Protea has developed an analytical model for our atmosFIR FTIR gas analyser that allows speciation of siloxanes on-line. The full spectrum technique of FTIR also allows for the measurement of the main gas components, CH₄ , CO₂ , NH₃ etc. providing real time, in-situ full gas composition analysis. In this paper we compare direct readings from a Protea FTIR with offline sampling methods. Comparisons have been made for siloxane calibration standards as well as real world gas data from both landfill and waste water.
