Title: Model development to predict hydrocarbon emissions from crude oil storage and treatment tanks
Principal Investigator / Author(s): Beckman, James R.
Contract Number: A4-045-32
Research Program Area: Emissions Monitoring & Control
Topic Areas: Stationary Sources
A computerized mathematical model was developed to predict hydrocarbon emissions from crude oil storage and treatment tanks. The model predicts emissions from tanks that experience working, breathing and flashing effects. Tanks simulated include wash, lease automatic custody transfer (LACT) and shipping tanks. Sensitivity analysis of all model input variables on emissions was performed along with a comparison of two test cases selected by ARB from 1977 WOGA field test data. One test case involving working and breathing effects showed excellent agreement in hydrocarbon emissions and total off gas values. The other test case dominated by flashing effects showed excellent agreement in total hydrocarbon emissions, but it had 80% more predicted total off gas when compared with WOGA data and propane + emissions were low by 230%.
