<p>An apparatus and method for improving the volumetric yield of well-head 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 (10) for heating the well-head gas stream to a predetermined temperature; valve means (11) associated with the heating means for reducing the pressure of the well-head gas stream in the heating means (10) to a predetermined reduced pressure to produce a reduced pressure and reduced temperature well-head gas stream; mixing means (5) for mixing the reduced pressure well-head gas stream with compressed gases and vapors wich have been subjected to multiple stages of compression; high pressure gas liquid separation means (20) for separating gases from liquids in the heated, reduced pressure well-head gas stream that have been mixed with compressed gases and vapors; second gas-liquid separation means (30) operating at a lower pressure than the high pressur gas-liquid separation means (20) for further separation of gases and vapors from the liquid separated by the high pressure gas-liquid separation means (20) 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 (92, 94) for introducing the compressed flashed components into the reduced pressure well-head gases in the mixing means.</p> |
