The purity of n-butane produced as a by-product of alkylation is 98%
Thread Content
The n-butane produced as a by-product of alkylation is usually treated as fuel gas, because its purity is not sufficient; does it need to be processed again to achieve 98% purity for use in the production of maleic anhydride? Is it also because the quantity is small, making it more convenient to sell it along with the by-produced natural gas? Which are the major domestic alkylation companies? I mainly want to know which are the major n-butane companies? It was found that Zhejiang Haiyue New Materials has a production capacity of 160,000 tons per year for butane; in 2015, its butane production was 20,000 tons. Are there any other companies with larger capacities?
Based on the data from the sulfuric acid alkylation process, the yield of n-butane produced as a by-product of the alkylation reaction is 13% of the total feed material; for a feed volume of 200,000 tons, this amounts to approximately 26,000 tons. The purity is generally not less than 98%. As one of the leading domestic suppliers of sulfate-based alkylation units, Zibo Junda Chemical Technology Co., Ltd. has constructed alkylation units for projects such as Linyi Jinyu, Anhui Haidé, Anhui Huiyu, and Sichuan Zhongteng. The scale of alkylation units is generally 200,000–400,000 tons. At present, over 90% of the units in China use the medium-temperature (7°C) sulfuric acid alkylation process (Zibo Junda), a small number employ low-temperature (-3°C) sulfuric acid alkylation (Lums), and only a very small fraction use other processes such as solid acid (KBR).
High-purity n-butane is difficult to buy and sell; maleic anhydride is a good business opportunity
We are developing solid acid molecular sieve catalysts. C4 alkylation to produce high-octane gasoline.
Just like stocks, this thing also exhibits wave-like trends; a device cannot keep making money or keep losing money. First, optimize the industrial structure and complete the industrial chain, and once it’s time to make profits, earnings will come in quickly
