煤气净化工艺煤气净化工艺synthetic gas clean-up process 普埃托拉诺(Puertollano)IGCC示范电厂中示范运行，脱硫效率较高。 (3)Sulfinol脱硫工艺:属化学吸收法，工艺流程如图4所示.吸收液是环丁矾和烷基醉胺的混合液，运行操作温度为40℃，对HZS和COS都有较强的吸收能力.溶剂无毒，不挥发，易被酸性气体所解析，压力越高越易吸收。其缺点是对煤气中的重烃和芳烃含量限制严格，造价较高。该工艺已应用于荷兰DemkolecIGCC示范电站。闪蔽气 陌.权衬|卜分l︸器︸.器Z，、塔呵11习收-︸却︸.﹃︸积、︸月二回︸吸收塔汽提浴丝叫闪燕糟一气厂‘||l!、一附七，气一净k，护 ‘，顾生上。上热交换器 图4 Sulfinol煤气脱硫工艺流程图 硫回收工艺是从吸收了硫化物的脱硫剂中分离并回收硫的过程。硫回收的方法大致有两种一种是以Clau，装t回收元素硫.另一种方法是将酸性气体送到硫酸厂，以硫酸的形式回收硫。IGCC示范电站多以克劳斯(Claus)装t回收元素硫，硫的纯度可以达到99%以上。 在claus装t中，HZS先被氧化成水和50:，然后在催化反应器中502和HZS反应生成H:O和元素硫，冷却后可得纯度很高的硫。一般要经过2一3级催化反应，才能获得较高的硫回收率。为了提高硫的回收率，有时需在claus装1后再加上荷兰壳牌(Shell)公司开发的Claus硫回收装置(简称SCOT装置)。Claus硫回收工艺流程有部分燃烧法、分硫法和燃硫法三种，前两种用得较多。Claus装里要求人口气体的HZS含量大于25%，小于此值则需补充嫩料进行嫩烧，运行成本提高。 离沮煤气净化工艺指在400~600℃下对煤气中的杂质进行脱除的过程，包括:高温除尘、高温脱硫、高温脱氨、高温脱除孩金属等过程。与低温煤气脱硫工艺相比，其优点是可大幅度减少因煤气冷却造成的热损失，从而使IGCC系统的净热效率提高。 离温煤气净化工艺尚未商业化，高温除尘和高温脱硫处于研究开发和示范阶段，高温除氨和高温除去毅金属的研究起步较晚，目前尚处于实验研究阶段。在高温净化的研究开发方面，美国居世界领先地位。 高温煤气除尘工艺已示范或试验的高温煤气除尘工艺的主要设备是烛状刚性陶瓷过滤器.它可以使净化后的煤气含尘浓度小于5 mg/m3(标)，粉尘粒度小于5拜m，能很好地满足燃气轮机的要求。但仍然存在脆裂、粉尘与陶瓷元件烧结及密封失效等问题，运行的稳定性较差，寿命较短，目前尚未达到商业化。
