LOW-TEMPERATURE CONDENSATION TECHNOLOGY IN FRACTIONATING OIL-ASSOCIATED GAS

摘要

Basic technological processes are considered in refining gaseous hydrocarbon raw material: low-temperature absorption LTA and low-temperature condensation LTC. The scheme for an LTA apparatus is given. The capital and working costs for LTA and LTC with turbine expanders are considered. Extraction coefficients are given for ethane, propane, and heavier hydrocarbon fractions from the use of five forms of LTC scheme.
