Total cryogenic processing capacity at Transportadora de Gas del Sur S.A.`s (TGS) Cerri complex in Bahia Blanca, Argentina, is being increased from 22 MMcmd to 40 MMcmd (776 to 1,410 MMcfd) with a future ethane-recovery capacity of 1,900 metric tons/day (mtd; 33,600 b/d) using Ortloff technology. Very high propane recovery can be maintained as the ethane recovery is controlled over a range of 1,000--1,900 mtd as needed to meet local ethane demand. Total NGL recovery can be increased from 2,600 mtd to 4,500 mtd without additional compression. The paper describes current operations, inlet-residue compression, train retrofit, C{sub 3} recovery, C{sub 2} rejection, C{sub 2} recovery, and the final dual-mode design.
