T504常温水解保护技术在CO造气工序脱硫系统的应用

Use of T504 Normal Temperature Hydrolysis Protection Technology in Desulfurization System of CO Gasification Step

介绍了一种常温水解保护新技术.该技术的侧流试验和1年的工业运行情况表明,可较好地解决高CO、高COS的水解脱硫难题.其脱硫效果好,在进口COS体积分数0.1%～0.2%的情况下,出口H2S和COS体积分数分别＜0.01%,操作温度低（50～70℃）,使用周期长（大于12个月）,操作费用低,并可耐受高COS的冲击.

An introduction is given to the new technology for the protection of normal temperature hydrolysis. The side-stream experiment of this technology and industrial operation for a year show that the difficult problem of high CO, high COS hydrolysis desulfurization can be satisfactorily solved. Its desulfurization results are good, at COS 0.1% -0.2% in the inlet, the exit has H2S 〈 0.01% COS 〈 0.01%, its operating temperature is low （50 - 70 ℃ ）, its service life is long （ longer than 12 months）, its operating cost is low, and it can resist high COS impact.
