this process comprises using unconventional processing of hydrocarbons , e . g . natural gas , for recovering c2 + and ngl hydrocarbons that meet pipeline specifications , without the core high capital cost requirement of a demethanizer column , which is central to and required by almost 100 % of the world &# 39 ; s current ngl recovery technologies . it can operate in ethane extraction or ethane rejection modes . the process uses only heat exchangers , compression and simple separation vessels to achieve specification ready ngl . the process utilizes cooling the natural gas , expansion cooling , separating the gas and liquid streams , recycling the cooled streams to exchange heat and recycling selective composition bearing streams to achieve selective extraction of hydrocarbons , in this instance being ngls . the compactness and utility of this process makes it feasible in offshore applications as well as to implementation to retrofit / revamp or unload existing ngl facilities . many disparate processes and derivatives are anticipated for its use .
