recommends improvements and modifications to the model to refine the predictions Copyright American Petroleum Institute Provided by IHS under license with API No reproduction or networking permitted without license from IHS Not for Resale SECTION INTRODUCTION The implementation of the 1990 Clean Air Act Amendments ( C U ) in the United States has caused the need for a reliable method to estimate and report hydrocarbon emissions from amine `,,-`-`,,`,,`,`,,` - based sour gas and natural gas liquid (NGL)sweetening units.To address this need, a software simulation package, called Amine Unit Air Emission Model (AMINECalc Version 1.0) was developed for the American Petroleum Institute (MI) by DB Robinson Research Ltd (DBRR) Many of the amine units in the field are fitted with sulfur recovery units (SRUs)to control hydrogen sulfide (H2S) andor carbon dioxide (C02) and not release volatile organic compounds (VOCs) and hazardous air pollutants (HAPS) to the atmosphere However, some amine units not have SRUs because they are used primarily to remove only CO2 fi-om natural gas without H2S;consequently some amine regenerators have the potential to release H A P s and VOCs to the atmosphere The AMINECalc model was developed primarily for those units having the potential to emit VOCs and HAPs to the atmosphere The calculation algorithm of this package is based on AMSIM, a commercial software package developed by DBRR Equipped with a rigorous non-equilibrium stage model and the PengRobinson equation of state, AMSIM was designed to provide accurate and reliable solutions for sow gas and liquefied petroleum gas processes The emphasis of this commercial software package was on acid gas (H2S and C02) removal, and its predictions have been constantly verified by actual plant data The objective of the current project is to develop a PC-based emission model to predict HAPS and VOCs fi-omflash tanks and solvent regenerators of a natural gas sweetening unit The AMINECalc model was re-engineered from AMSIM and enhanced to accommodate three types of calculations: mass balance calculation, gas process simulation, and NGL process simulation The emphasis is on HAPs which include benzene, toluene, ethylbenzene and xylenes (BTEX), as well as VOCs emitted from amine units Copyright American Petroleum Institute Provided by IHS under license with API No reproduction or networking permitted without license from IHS Not for Resale `,,-`-`,,`,,`,`,,` -
