First commercial transport, coal-gasifier contract awarded

By Scott Jenkins |

A contract for the world’s first commercial transport-gasification facility was awarded to KBR (Houston, www.kbr.com) by Beijing Guoneng Yinghui Clean Energy Engineering Co. for a coal power plant in China’s Guangdong province. The two-phase project will showcase KBR’s transport integrated gasification (TRIG) technology, which is designed specifically for the efficient conversion of low-rank coal to synthesis gas (syngas). The first phase of the project will be a 120-MW integrated gasification combined cycle (IGCC) power plant, scheduled for completion in 2011. That facility will be followed by an 800-MW IGCC plant with TRIG technology, scheduled for completion in 2012. TRIG technology includes a refractory-lined, circulating-bed gasifier that enables economic conversion of low-grade coals, such as lignite, sub-bituminous and high-ash, into syngas. The circulating-bed gasifier uses a dry feed and operates at temperatures below the melting point of ash, so it is suitable for lower-cost fuels with high ash or moisture content, KBR explains. “Coals with up to 50% ash can be processed in the TRIG gasifier,” the company notes. In the riser portion of the gasifier unit, TRIG takes advantage of the reactivity…
