近期,BP公布了两项低成本生产乙酸和乙烯的新技术。“SaaBre”技术的突破性在于它是一种通过合并三步法过程将合成气直接转化为乙酸的工艺,无需提纯一氧化碳或采购甲醇。据悉,该反应过程不含碘化物,还降低了对特殊金属材料的需要。BP称,目前占主导地位的甲醇羰基化工艺已经达到了极限,因此该公司几年前就决定开发新技术,以便从根本上提高规模化生产乙酸的经济性。与甲醇羰基化法技术相比,该“SaaBre”技术有望显著降低乙酸的生 Recently, BP announced two new technologies for low-cost production of acetic acid and ethylene. The breakthrough in Saabre technology is that it is a process that converts syngas directly to acetic acid by a combined three-step process without the need to purify carbon monoxide or procure methanol. It is reported that the reaction process does not contain iodide, but also reduces the need for special metal materials. BP said that the current methanol carbonylation process has reached its limit, so the company decided a few years ago to develop new technologies to radically improve the economics of large-scale production of acetic acid. Compared with methanol carbonylation technology, the “SaaBre” technology is expected to significantly reduce acetic acid
