针对高炉煤气羰基硫催化水解和H₂S吸附相结合的燃烧前脱硫工艺，分别应用Aspen Plus和Aspen Adsorption软件进行模拟，探究能耗的关键影响因子温度和压力对总硫脱除和能耗的影响，识别满足减排标准的低能耗脱硫情景。结果表明，水解压力对能耗和总硫含量变化不敏感；吸附压力升高，总硫含量降低，但对能耗变化不敏感；水解温度和吸附温度是影响脱硫和能耗的关键因素，水解温度升高会导致总硫含量降低和能耗升高，吸附温度升高会导致总硫含量升高和能耗降低。

A desulfurization process for blast furnace gas before combustion, which combines the catalytic hydrolysis of carbonyl sulfur and the adsorption of hydrogen sulfide, is proposed.It is simulated respectively by Aspen Plus and Aspen Adsorption software to explore the influences of temperature and pressure on total sulfur removal and the associated energy consumption, and to identify the low energy consumption desulfurization scenario that meets the emission reduction standard.Results show that hydrolysis pressure has not sensitive impact on energy consumption and total sulfur content;When adsorption pressure increases, total sulfur content will decrease, but energy consumption will not be affected obviously;Hydrolysis temperature and adsorption temperature are the key factors affecting desulfurization and energy consumption;The higher hydrolysis temperature will lead to a decrease of total sulfur content and an increase of energy consumption, while the increase of adsorption temperature will lead to an increase of total sulfur content and a decrease of energy consumption.
