摘　　要：对粉煤加压气化中分别采用CO_2输煤和N_2输煤的两种工艺进行了分析比较,结果表明:采用CO_2输煤比采用N_2输煤的操作费用会降低约4%,投资高3%。并由此总结出了煤化工装置不同产品应选用不同的输煤工艺及适合的流程配置的规律。Analysis and comparison of the C〇2 and N2 as pulverized coal carrier gases in coal gasification process usher the results that compared with the latter, applying the former one can decrease the operating cost by 4% and increase the investment by 3% . A rule is summed up therefrom that different pulverized coal carrier gases and applicable processes shall be selected for different products of coal chemical units.
