摘要
针对农药等精细化工领域中大多对CO气体需求规模小、不需要H2等特点，从合成气组成、物料消耗、操作费用、投资费用等方面，对适于小规模生产CO气体的小炉型焦炭气化、大炉型焦炭气化、天然气转化、甲醇裂解4种制气工艺路线进行评价并给出选择建议。通过对比认为，两种焦炭气化工艺更加适合于仅需要CO气体的农药领域。
Abstract
Given the small-scale demand for CO gas and zero demand for H2 in the fine chemical industries such as pesticide industry,four gas production processes suitable for small-scale CO gas production,including small furnace type coke gasification,large furnace type coke gasification,natural gas conversion and methanol cracking,are evaluated from the composition of syngas,material consumption,operation cost and investment cost.The suggestions on selection are given.Through comparison,it is concluded that two coke gasification processes are more suitable for the pesticide industry which only needs CO but need not H2.
