Description:
This report documents the testing of a new technology that recovers and utilizes vapors from crude oil storage tanks employed in the oil production and processing industry. The COMM Engineering, USA Environmental Vapor Recovery Unit (EVRU) is a non-mechanical eductor, or jet pump, that collects low-pressure vent gas from a site's condensate storage tanks, pressurizes it, and injects it into a natural gas pipeline for sale. It is designed to reduce or eliminate emissions of methane, carbon dioxide, volatile organic compounds, and hazardous air pollutants present in vent gas. The EVRU was tested for 8 days at a gas and condensate exploration and production facility near McAllen, Texas, that handles separation of natural gas and crude oil condensate product, gas compression, and gas dehydration from wells in the area.
The performance verification parameters tested are gas recovery rate, annual gas savings and emission reductions, value of recovered gas, and total installed cost. The unit recovered an average of 177 +/- 39 Mcf of vent gas per barrel of oil processed. It is estimated that 63.9 million scf/yr can be recovered with the EVRU. The value of recovered gas would be $349,318 per year. The total installed cost are estimated to be $107,958.
