Eastman plans a dramatic increase in chemicals production from syngas
By Chemical Engineering |
Eastman Chemical Co. (Kingsport, Tenn.; edlinks.chemengonline.com/6899-534), which has been producing chemicals via coal gasification (flowsheet) since 1983, will build a $l.6-billion plant in Beaumont, Tex., that will roughly quintuple the size of its current production of chemicals from synthesis gas. The company plans to share ownership 50â€“50 with a financial equity investor. Scheduled for startup in 2011, the plant will play a significant role in Eastmanâ€™s plan to increase chemicals production through gasification from 20% to 50% of its total volume.
The plant will gasify 2.4-million ton/yr of petroleum coke to obtain a syngas of hydrogen and carbon monoxide, plus carbon dioxide. It will have the potential to produce up to 70-billion scf/yr of H2, 255,000 ton/yr of ammonia and up to 225-million gal/yr of methanol. About 85â€“90% of the CO2 from gasification will be recovered and sold for enhanced oil recovery. Part of the H2 will be sold to Air Products and Chemicals, Inc. (Allentown, Pa.), which will build and operate an air-separation plant to supply more than 7,000 ton/d of O2 for the gasifier, plus N2 for the ammonia plant. The gasifiers will be licensed from GE Energy (Atlanta, Ga.), which acquired the gasification…
