Next generation processes for NGL/LPG recovery

Up to now, Ortloff`s Gas Subcooled Process (GSP) and OverHead Recycle Process (OHR) have been the state-of-the-art for efficient NGL/LPG recovery from natural gas, particularly for those gases containing significant concentrations of carbon dioxide (CO{sub 2}). Ortloff has recently developed new NGL recovery processes that advance the start-of-the-art by offering higher recovery levels, improved efficiency, and even better CO{sub 2} tolerance. The simplicity of the new process designs and the significantly lower gas compression requirements of the new processes reduce the investment and operating costs for gas processing plants. For gas streams containing significant amounts of carbon dioxide, the CO{sub 2} removal equipment upstream of the NGL recovery plant can be smaller or eliminated entirely, reducing both the investment cost and the operating cost for gas processing companies. In addition, the new liquids extraction processes can be designed to efficiently recover or reject ethane, allowing the gas processor to respond quickly to changing market conditions. This next generation of NGL/LPG recovery processes is now being applied to natural gas processing here in the US and abroad. Two of the new plants currently under construction provide practical examples of the benefits of the new processes.
