Continuing July 2022 tip of the month, this tip demonstrates applications of the models developed based on the experimental VLE and VLLE data measurements presented in the Gas Processors Association (GPA) research report RR-242. The models will be used for estimation of solubilities of a mixture consisted of Benzene, Toluene, and Ethylbenzene in loaded amine solution with CO2 and/or H2S. This is important because all BTEX components, both soluble and absorbed, in the contactor will be removed from the solution in the flash drum and regenerator, the emissions will be essentially equal to the amount absorbed. Correctly estimating the quantity of absorbed BTEX and understanding the factors that affect absorption levels is critical to ensure the proper mitigation methods are provided to meet the required emission limits.
