Finding the right air compression solution for your xTL process is vital to ensuring a profitable operation from day one. High power, volume and reliability are essential in order to feed the massive volumes of air required for such processes at the gas reforming stage or for the cryogenic separation process used to convert natural gas to syngas.
With its high-power, high-volume compressor trains at the heart of the conversion process, Siemens is not only a prime supplier to many current large-scale xTL projects around the world, but is also already capable of providing new machines for next-generation xTL plants. What’s more, Siemens products and services, all from a single source, help to integrate utilities, run plants at optimal levels of efficiency and ensure maximum availability:
Utilities are of particular concern with regard to the internal energy integration of a plant. For instance when matching the large amounts of heat energy available from the syngas and FT process stages with the plant’s power demand. One of the challenges is to reduce operational expenditure (OPEX) through an overall optimization of energy efficiency.
SASOL’s Secunda CTL plant, Johannesburg, South Africa
Demonstrating technical feasibility and the economies of scale demanded of 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. Scope of Siemens delivery:
all designed, manufactured and installed by Siemens. The unit was built as the most powerful of its kind in the Middle East and numbers among the largest worldwide, supplying some 100,000 cbm/h of oxygen to a petrochemical refining process.
