一种饱和热水塔高水气比CO变换工艺
摘要：
本发明涉及到一种饱和热水塔高水气比CO变换工艺，其是将粗煤气气液分离后依次送入饱和塔、第一变换炉、第二变换炉、第三变换炉和热水塔，最后经与热水塔内的工艺循环水、净化工艺冷凝液和中压锅炉水进行传热传质后得到符合要求的变换气。本发明所提供的CO变换工艺创造性地将饱和塔和热水塔引入到高浓度高水气比CO变换系统中，并且对现有的热水塔结构做了改进，在热水塔的中部增加了喷淋入口。本发明所提供的饱和热水塔高水气比CO变换工艺解决了现有技术中蒸汽消耗大、能耗高，预变换催化剂使用寿命短、失活快、更换频繁等问题。
摘要（英）：

The invention relates to a saturated hot water tower high-water-steam-ratio CO transformation process, which comprises the following steps of: performing gas-liquid separation on raw gas, and feeding into a saturated tower, a first transformation furnace, a second transformation furnace, a third transformation furnace and a hot water tower in sequence; and performing heat transfer and mass transfer with process circulating water, purified process condensate and medium-pressure boiler water in the hot water tower to obtain qualified transformed gas. In the CO transformation process provided bythe invention, the saturated tower and the hot water tower are creatively introduced into a high-concentration high-water-steam-ratio CO transformation system, the structure of the conventional hot water tower is improved, and the middle part of the hot water tower is additionally provided with a spray inlet. By adopting the saturated hot water tower high-water-steam-ratio CO transformation process provided by the invention, the problems of high steam consumption, high energy consumption, short service life of pre-transformation catalyst, quick deactivation, frequent replacement and the like existing in the prior art are solved.
