Fluor Cryo-Gas Process by Fluor Enterprises, Inc.
The Fluor Cryo-Gas process for natural gas liquids (NGL) recovery is a complete portfolio of patented or patent pending turbo-expander-based NGL recovery processes. It is tailored to meet a wide variety of feed gases and NGL recovery requirements. Description: The Cryo-Gas process presented in the diagram is the vapor reflux absorption process (VRAP). VRAP is a two column process that can achieve 99.9% propane recovery without external refrigeration. It features low capital cost, weight and footprint and has low energy and utility requirements.
Four additional Fluor Cryo-Gas process schemes are: Fluor’s patent pending two columns, high-pressure absorber process (TCHAP) is the most energy efficient NGL recovery process for feed gas pressures exceeding 1,000 psig. TCHAP achieves up to 85% ethane recovery with propane recovery in excess of 99%. Alternately, the process can achieve propane recoveries exceeding 99% while rejecting ethane. It is resistant to carbon dioxide (CO2) freezing and requires 30% less residue gas compression hp than competing processes. TCHAP can produce product quality ethane with
