ABSTRACT:
Gaseous hydrocarbon streams such as natural gas streams are acid gas depleted and reduced to pipeline specification moisture content using a single absorbent: a particular amino ethyl ether; in two steps providing in sequence, counter-current multi-stage absorption and at least one dehydrating contact stage with fresh absorbent at low temperature, to effect moisture removal down to 4 pounds of water per MMSCF of gas and even lower water content. The use of a single chemical as absorbent rather than two absorbents means lower capital investment and operating expense than heretofore required to get pipeline specification gas.
