Happy May Day 2024! Safety first. Let’s give praise and support to the achievements made in China’s chemical technology and equipment sector. **********************【Ten Years of Development in Chemical Equipment】A continuously updated summary post is available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Forum Website) ***************** In September 2014, news came from Tongliao City, Inner Mongolia: the 100,000 tons per year coal-based oxalic acid production project operated by Inner Mongolia Tongliao Jinmei Chemical Co., Ltd. had completed its commissioning tests, with all stages of the oxalic acid production process functioning properly, and qualified oxalic acid products were successfully produced. This marks the successful industrial operation of the world’s first new process plant for producing oxalic acid from coal. 　　It is reported that in order to diversify its product portfolio and extend the coal chemical industry chain, Inner Mongolia Tongliao Jinmei Chemical Co., Ltd. adjusted the original design of its initial project with an annual production capacity of 200,000 tons of ethylene glycol. As a result, it developed a process for producing oxalic acid from coal; this process allows for the production of 100,000 tons of oxalic acid alongside the existing ethylene glycol production. The purity of the oxalic acid produced in pilot tests currently exceeds 99.5%. 　　This facility is the world’s first production line to utilize coal-based oxalic acid technology, covering a total area of 3,000 square meters. The coal-based oxalic acid production technology used by Jinmei Chemical Industry is based on traditional methods; it involves hydrolyzing a portion of the intermediate product, oxalate, at the later stage of coal chemical production to produce oxalic acid and methanol. The methanol involved can further be used to produce methyl nitrite, which is then used to create oxalates, thereby achieving recycling. Oxalic acid produced using this process not only has environmental advantages but also features low costs and high purity.
