我厂甲酸装置 1 994年建成投产 ,设计能力50 0 0 t/ a。工艺是利用精炼再生气 ( CO含量≥60 % )与碱液 ( Na OH浓度≥ 2 0 % )反应生成固体甲酸钠 ,再与浓硫酸反应而制得。由于原料烧碱中氯离子含量较高 ,使成品甲酸中氯含量高 ,产品品位不高。与采用羰基合成法生产的甲酸相比
Our plant formic acid plant was put into operation in 1949, with a design capacity of 50 0 t / a. Process is the use of refined renewable gas (CO content ≥ 60%) and lye (Na OH concentration ≥ 20%) to form solid sodium formate, and then with the reaction of concentrated sulfuric acid. Due to the high content of chloride ion in the raw material caustic soda, the chloride content in finished formic acid is high, and the grade of the product is not high. Compared with formic acid produced by the oxo process
