ABSTRACT The recovery of natural gas liquids and the preparation of a merchantable natural gas from hydrocarbon raw natural gas streams from natural gas or oil wells is often carried out using a gas stream refrigeration process to condense liquids out of the raw gas stream and then a fractionation tower to provide a conditioned and stabilized liquid product. Such units are usually assembled of the following individual components or units, 1) Gas-to-gas exchanger 2) Gas chiller 3) Low temperature separator 4) Fractionation column 5) Hydrate inhibitor injection system 6) Hydrate inhibitor removal system 7) Hydrate inhibitor regeneration heating system 8) Hydrate inhibitor pumping system 9) Heat source for fractionator 10) Refrigerant supply system 11) Fractionation column pressure control system 12) Fractionation column gas overhead gas handling system Each of the above are tied together with piping and control instruments to provide a functional unit that will produce a merchantable natural gas and a stabilized liquid product. In the present invention, many of the above functions are contained within one pressure shell instead of many to provide a lower cost and more heat and power efficient natural gas stream Natural Gas Liquids Recovery Unit. - 1 -
