Gas-to-Liquids (GTL), Coal-to-Liquids (CTL) - Secunda
Proving technical feasibility and the economies of scale required
from commercially viable GTL/CTL front-end technology, this
electric-motor driven compressor delivers approx. 700,000 cbm/h of
air to the air separation unit of SASOL’s Secunda CTL plant near
Johannesburg, South Africa, the largest of its kind worldwide.

Project - Air Seperation - Gulf regionSiemens has been contracted to supply a large-scale compression
solution for an air separation plant in the Gulf region. At the
heart of the solution will be a 700,000- cbm/h main air compressor
(STC-SR) and an integrally geared booster air compressor (STC-GV),
both powered by a double-ended 81-megawatt (MW) steam turbine — all
designed, manufactured and installed by Siemens. Scheduled for
start-up in the fourth quarter of 2007, the unit will be the most
powerful of its kind in the Middle East and range among the largest
worldwide, supplying some 100,000 cbm/h of oxygen to a petrochemical
refining process.
