Abstract
A major independent oil and gas producer (Producer) with operations located on the Outer Continental Shelf of the Gulf of Mexico had several facilities damaged by Hurricane Ike. As a part of restoring operations, one of the offshore platforms was refurbishment included upgrading the production train to handle additional oil and gas production from other nearby production platforms. The additional production to the platform required a vapor recovery system to recover facility flash project team chose the scroll compressor vapor recovery unit (VRU) to recover and recompress the flash gas. The project was the first application of scroll compression technology for vapor recovery in an offshore environment.
The Producer installed the VRU allowing the facility to recover flash gas from the oil storage tanks and excess unused flash gas from the oil treater. The average volume recovered was approximately 58,000 standard cubic feet of natural gas per day during the initial phase of the project. The methane content of the recovered natural gas was approximately 69 percent by volume. The estimated methane recovered was US tons per day and the estimated recovery of greenhouse gases were US tons per day CO2e. Volatile organic compounds (VOC) recovered were US tons per day. The scroll compressor VRU met the regulatory requirements of the U
