Hydrate Formation in Chevron Mabee Unit for NGL Recovery and CO2 Purification for EOR
In the early 1990's, Chevron installed a new process to recover natural gas liquids (NGLs) from recycled CO2 in their Rangely Weber Sand Unit. The facility was designed based on a patent issued in June of 1988 (U.S. Patent # 4,753,666). The process, as claimed in the patent, used a refluxed distillation tower to produce an overhead stream virtually free of n-butane and heavier components and a bottoms stream containing the majority of the heavier components. Based on the success of the Rangley plant's operation, a similar facility was designed and fabricated by Dickson Process Systems and installed in Chevron's Mabee field near Midland, Texas.
