Turboexpanders aid condensate recovery
Turboexpander plants built by Fluor are operating in 18 locations throughout the world, with the first one having been built in 1963. These plants, plus those under construction, account for a combined gas capacity or more than 4,000 MMscfd. In both gas-processing and cryogenic operations, the turboexpander is gaining wide acceptance in such areas as North and South America, the Middle East, and N. Africa. In a typical plant, feed gas is first dehydrated before being chilled by heat exchange with the gas product from the turboexpander. Condensate liquids are separated from the gas stream which is then expanded. Further condensed liquids resulting from the expansion-cooling effect are separated for fractionation. The degree of expansion can be varied to recover up to 60 to 90% of the ethane contained in the feed gas. The most efficient use of turboexpander refrigeration is dependent upon the product required.
