摘要

传统酸气净化技术存在能耗高、羰基硫（COS）及硫化氢（H

S）净化不达标等问题。利用Aspen工艺流程模拟软件，对添加了羰基硫催化水解装置的净化单元（醇胺法）进行优化，考察了溶液循环量、溶液进塔温度、吸收压力和填料高度等操作参数对气体净化效果和能耗的影响。结果表明，一定程度降低溶液循环量、溶液进塔温度、吸收压力和填料高度可以减少CO

吸收，从而提高商品气产率。在优化条件（溶液循环量262 m

/h、溶液进塔温度40 ℃、吸收压力4.5 MPa和填料高度15.5 m）下，可实现酸气中H

S完全脱除，出口净化气体中CO

含量（物质的量分数）降至2.95%，再生能耗控制在3.4 GJ/t，年节约低压蒸汽28.8 × 10

t，能耗显著降低。

Abstract

Traditional acid gas purification technologies face issues such as high energy consumption and failure to meet the purification standards for carbonyl sulfide (COS) and hydrogen sulfide (H

S). Using Aspen process flow simulation software

a purification unit (alkanolamine process) that incorporates a carbonyl sulfide catalytic hydrolysis device was optimized. The effects of operating parameters such as solution circulation rate

solution inlet temperature

absorption pressure and packing height on gas purification efficiency and energy consumption were investigated. The results show that appropriately reducing the solution circulation rate

solution inlet temperature

absorption pressure and packing height can decrease CO

absorption

thereby improving the yield of the purified gas. Under optimized conditions (solution circulation rate of 262 m

solution inlet temperature of 40 ℃

absorption pressure of 4.5 MPa and packing height of 15.5 m)

complete removal of H

S from acid gas was achie

ved. The CO

content (mole fraction) in the purified gas can be reduced to 2.95%

and the regeneration energy consumption can be controlled at 3.4 GJ/t. The annual savings in low-pressure steam amounted to 28.8 × 10

leading to a significant reduction in energy consumption.
