ABSTRACT:
An apparatus and method for improving the volumetric yield of wellhead gas and the hydrocarbon composition of the liquid condensate from a natural gas well by the use of multiple stages of gas-liquid separation and gas compression including the use of heating means for heating the wellhead gas stream to a predetermined temperature; valve means associated with the heating means for reducing the pressure of the wellhead gas stream in the heating means to a predetermined reduced pressure to produce a reduced pressure and reduced temperature wellhead gas stream; mixing means for mixing the reduced pressure wellhead gas stream with compressed gases and vapors which have been subjected to multiple stages of compression; high pressure gas liquid separation means for separating gases from liquids in the heated, reduced pressure wellhead gas stream that have been mixed with compressed gases and vapors; second gas-liquid separation means operating at a lower pressure than the high pressure gas-liquid separation means for further separation of gases and vapors from the liquid separated by the high pressure gas-liquid separation means to produce flashed gases, vapors and liquid components; and gas compression means for compressing and liquifying the flashed components recovered from the second gas-liquid separation means and means for introducing the compressed flashed components into the reduced pressure wellhead gases in the mixing means.
