The Challenges of Retrofitting Upstream Facilities For Tank Venting To Flare

Written and Presented by Tucker Payne

Abstract:

Over the last decade volatile organic compound (VOC) emissions from onshore production pads have come under closer scrutiny with passing of Code of Federal Regulations 40 Part 60 Subpart OOOO and OOOOa (commonly referred to as “Quad O” and “Quad Oa”) regulations. Facilities constructed prior to Aug. 23, 2011 are exempt from these regulations unless a well or facility is “modified”. Modified facilities with existing tanks expected to emit over 6 tons of VOCs per year fall under the regulation and are therefore required to reduce VOC emissions by 95%. This paper details the process for designing and implementing a tank vent capture system and examines the challenges recently encountered during a retrofit of 50+ existing modified facilities in the Williston Basin. These challenges often include high capital costs for older facilities/wells, limitations of existing equipment, and non-optimized process flow, creating higher potential to emit at tanks. Utilizing the lessons learned from these retrofits can save time and costs on future modified facilities as well as help avoid these issues in the design phase of new facilities.
