NGL PROCESS FOR SEPARATING AND RECOVERING NGLS FROM HYDROCARBON STREAMS

摘要

This process can be used to recover C2 + and NGL hydrocarbons that meet the pipeline specifications without the need for key high cost of demethanating columns that are at the center of the world''s current NGL recovery technology and require nearly 100% Including using a unique treatment of the gas. The process may operate in an ethane extraction or ethane removal mode. The process uses only a heat exchanger, a compression vessel and a simple separation vessel to obtain a specially prepared NGL. The process may include cooling the natural gas, expansion cooling, separating the gas stream and the liquid stream, recirculating the cooled stream to exchange heat, and selectively extracting hydrocarbons, in this case selective extraction of NGL RTI ID = 0.0 recycle /RTI The simplicity and availability of such a process makes the process feasible in applications outside of the country, in addition to running to retrofit, retrofit or remove existing NGL facilities. Many different processes and derivatives are expected to be used therefor
