醋酸原料的变更与生产醋酸工艺路线的优选

The Variation of Acetic Acid Feedstock and Optimization Selection of Produce Acetic Acid Process

分析国内外乙炔、乙醇、丁烷、石脑油、乙烯、甲醇等原料生产醋酸工艺路线的历史过程和发展趋势并优选醋酸原料。采用煤或天然气产品甲醇作为醋酸原料的比重愈来愈高。低压甲醇羰基合成法生产醋酸工艺流程先进、产品收率高、综合能耗低,该技术代表当前醋酸生产的最新工艺和发展方向。由于新金属材料的出现,仪表控制水平的提高,低压甲醇羰基合成生产醋酸的技术已日臻完善。随着大型醋酸装置的投产,我国醋酸市场将出现供大于求的态势。

Analyse history course and development trend of produce acetic acid process from feedstock of acetylene, ethanol, butane, naphtha, ethylene, methanol etc. and find more and more produce acetic acid for methanol feedstock from coal or natural gas product. The low pressure methanol carbonylation produce acetic acid process is advanced process, higher product yield, lower specific energy consumption. So low pressure methanol carbonylation process is best currently produce acetic acid process. The low pressure methanol carbonylation process is most perfection now after has discovered new metal material and has improved instrument control level. The national acetic acid market will supply exceed demand when large scale acetic acid plant put into production.
