Our leadership in supplying large-scale cryogenic oxygen plants to the gasification industry has led to Air Products' position as a premier gasification company. In Jazan, Saudi Arabia, we built six air separation units that will supply over 75,000 tons per day (TPD) of oxygen and nitrogen to an integrated gasification and combined cycle (IGCC) complex. These mega plants are specially designed with the latest technology to safely and reliably supply the IGCC complex with oxygen for gasification and nitrogen as diluent for the combined cycle units.
We also will build two large air separation trains as part of a contract to supply syngas for a multi-billion-dollar mono-ethylene glycol project in Hohhot, China that mark the next generation of oxygen production for gasification. A patent-pending, new process cycle will minimize steam consumption while preserving operating flexibility, and an advanced form of radial flow temperature swing adsorption will purify the air before entering the cryogenic area of the process. This technology delivers lower pressure drop than alternatives, further reducing energy consumption while minimizing footprint.
As the market moves to larger train sizes to supply oxygen to mega gasification projects, Air Products continues to push the boundaries and build on our track record of successful large-scale oxygen plants.
The Netherlands has long sourced natural gas from its domestic Groningen Field, however, that extraction has resulted in seismic activity, which now requires a switch to imported gas. Since imported natural gas is incompatible with the applications currently served by the Groningen source, N.V. Nederlandse Gasunie selected Air Products to supply three specialized nitrogen generator units that will be used to condition imported natural gas.
On-stream in 2021, these nitrogen generators will be among the most energy efficient ever constructed, reducing carbon dioxide emissions an estimated 21,000 tons per year compared to previous technology. This is made possible by a new process design and improvements in compression efficiency. In addition, the air separation units are designed to quickly ramp production from a cold start to closely match gas demand and further reduce energy consumption.
"Our selection points to our record of expertise in air separation," said Paul Hoogeveen, general manager-Rotterdam Tonnage at Air Products. "Time and experience have taught us how to get the best out of the cryogenic air separation process, both in terms of safety and high efficiency."
