摘要
介绍了大型甲醇和醋酸联合装置的关键生产技术,研究证明,采用大型壳牌煤气化装置以高浓度CO的粗煤气为原料制备甲醇和醋酸,通过选择合适的CO变换率、用CO2替代N2作为煤粉输送气和反吹气、低温甲醇洗配套冷箱技术、提纯CO作为醋酸的原料气等技术,达到联合装置节能、减排、增产、减少设备投资等目的。
The key technique of large scale methanol and acetic acid complex unit are introduced, the study shows, producing methanol and acetic acid with Shell coal gasification plant, using high concentration CO as feedstock we can reach the target of complex unit saving energy, reducing waste, increasing production and reducing equipment investment by some techniques such as, selecting proper CO shift ratio,using CO2 instead of N2 as transportation gas and back gas,low temperature methanol washing depurating CO as feed gas for producing acetic acid corollary equipped with cold -box.
