IGCC粗煤气高温脱硫技术的研究进展
|
摘要
整体煤气化联合循环(IGCC)是洁净煤发电技术的重要发展方向。煤气化产生的粗煤气一般含有大量的H2S,进入燃气轮机内会对叶片造成腐蚀,影响汽轮机寿命。传统低温脱硫技术先将高温煤气冷却,待H_2S被液体吸收后再重新加热煤气,造成极大的能量损失。采用固体可再生吸附剂高温脱硫可省去冷却和再加热的步骤,提高热效率,简化净化设备。金属氧化物是高温煤气脱硫剂研究的主要方向,复合金属氧化物因其具有很高的硫容且与H_2S有很强的亲和力而大大提高了脱硫性能,具有良好的脱硫效果,应用前景广阔。
Integrated Gasification Combined Cycle( IGCC) power generation technology is an important direction of clean coal power generation technology. The crude gas produced by coal gasification generally contains a large amount of H_2S,and its entrance into the gas turbine will cause corrosion on the blades and affect the service life of the steam turbine. In the traditional low-temperature desulfurization technology,high-temperature gas is cooled down at first,and then the gas is re-heated after H_2S solution absorption,which causes great energy losses. Using solid renew-able adsorbents for high temperature desulfurization can dispense with cooling and re-heating steps,improve thermal efficiency and simplify the purification equipment. Metal oxides are the main research direction of high temperature gas desulfurizers. Because of their high sulfur content and strong affinity with H_2S,which can greatly improve the desulfurization performance,the composite metal oxides have good desulfurization performance and broad application prospects.
