4. Electrolysis     When electric current passes through electrolytic solution or molten electrolyte, the chemical change caused on two poles is called electrolysis. Electrolysis has a wide range of functions in industry. The smelting of many non-ferrous metals (sodium, potassium, magnesium, lead, etc.) and rare metals (zirconium, hafnium, etc.), the refining of metal copper, zinc, aluminum, etc., as well as the preparation and electroplating, electropolishing, anodic oxidation, etc. of many basic chemical industry products (Hydrogen, oxygen, chlorine, caustic soda, potassium chlorate, hydrogen peroxide, etc.) are all realized by electrolysis.     Such as salt water electrolysis production sodium hydroxide, hydrogen, chlorine, electrolysis water production, etc. Risk analysis and fire prevention points in the

1. Oxidation Such as ammonia oxidation to nitric acid, toluene oxidation to benzoic acid, ethylene oxidation to ethylene oxide, etc.     (1) Fire risk of oxidation     ①Oxidation reaction requires heating, but heat will also be released during the reaction, especially the catalytic gas phase reaction. Generally, the oxidation reaction will be carried out at a high temperature of 250-600 ℃. If the heat generated by the reaction is not removed in time, the temperature will rise rapidly or even explode.     ② For some oxidations, such as the oxidation of ammonia, ethylene and methanol vapor in the air, the material ratio is close to the lower explosion limit. If the ratio is out of

At the end of August, 1,200 cylinders of argon gas from Suzhou JinHong Gas were exported to Bolivia. This shipment is the first batch of goods exported by JinHong Gas to South America. From communicating with customers in the early stage to confirming the order, receiving the last payment, the time span is almost half a year. It has experienced the price increase of steel cylinders due to the huge price increase in steel, as well as the stage of skyrocketing ocean freight caused by the COVID-19, our customer initially used the FOB trade term, but his forwarder couldn’t confirm booking containers for a very long time, eventually led to the cargo was stuck in the

  According to the statistics of China Coal Processing and Utilization Association, both the production and consumption of hydrogen energy in China have exceeded 25 million tons in 2020，making China the world’s largest hydrogen producer. The foreign gas giants started early and established a strong competitive position in the production technology of hydrogen field. China’s local high-purity hydrogen enterprises mainly compete in the retail hydrogen supply market, and most customers are various electronic companies and non-ferrous metal deep processing enterprises, etc., which is a typical market of “large number of customers but small amount of individual consumption”.     As an important gas supplier in China, JinHong Gas has a hydrogen production capacity of 44.6
