With the development of sulfur recycling, my country’s dependence on foreign countries for sulfur is expected to gradually decrease

Sulfur, also known as sulfur, colloidal sulfur, and sulfur block, is in the form of light yellow lumpy brittle crystals or light yellow powder. It has a special odor, is insoluble in water, is slightly soluble in alcohol and ether, and is easily soluble in carbon disulfide. In its natural state, it is organic Sulfur, natural sulfur, hydrogen sulfide, sulfate ore, metal sulfide ore and other forms exist. Sulfur can be divided into natural sulfur mines and recycled sulfur according to different sources; according to different uses, it can be divided into industrial grade sulfur, food grade sulfur, etc.; according to different crystal forms, it can be divided into three major categories: monoclinic sulfur, orthorhombic sulfur, and amorphous sulfur. kind.

Sulfur can produce bromine, chloroacetic acid, concentrated/dilute sulfuric acid, copper sulfide, monoammonium phosphate, sulfur hexafluoride, sodium metabisulfite and other products, and is widely used in pesticides, rubber, printing and dyeing, pigments, fertilizers, medicines, explosives, washing Agents, flame retardants, fire extinguishing agents, batteries, insulating materials, photosensitive materials, synthetic resins and other fields.

my country’s sulfur production mainly comes from two ways: natural mining and recycling. my country’s natural sulfur ore resources are scarce, and domestic sulfur output is not high, which cannot meet the huge demand in the sulfur downstream application market. Therefore, recycled sulfur is the main source of my country’s sulfur production, accounting for more than 96.4% of my country’s total sulfur production. Sulfur recovery refers to the process of converting sulfur by-products generated by desulfurization of petroleum, coal, iron ore and other products into elemental sulfur. It can not only recover sulfur resources and provide essential raw materials for industrial development, but also protect the environment and prevent hydrogen sulfide, etc. Toxic gases cause damage to the atmosphere.

According to the “2023-2028 Sulfur Industry Market In-depth Research and Investment Prospects Forecast Analysis Report” released by the Industrial Research Center, in recent years , my country’s sulfur industry is developing well, and sulfur output continues to rise. In 2022, the output will exceed 9.4 million tons. On the one hand, my country is rich in coal resources and is the world’s largest coal producer and consumer. Raw coal recycling is one of the main ways to recover sulfur in my country. As my country’s scientific and technological level continues to rise, domestic desulfurization and sulfur treatment technology has gradually improved, greatly improving the efficiency of sulfur recovery, and the sulfur output of raw coal recovery has gradually increased. On the other hand, under the background of “carbon peak” and “carbon neutrality”, my country’s new energy vehicle industry is developing rapidly, and the output of new energy power batteries is growing rapidly. As one of the main production materials for new energy power batteries, sulfuric acid has seen increasing market demand, further promoting the development of my country’s sulfur industry.

Industrial analysts said that my country is a major importer of sulfur, with an import dependence as high as 60.3%. South Korea, Japan, Iran, Canada, and the United Arab Emirates etc. are the main importing countries of sulfur in my country. Among them, South Korea is my country’s largest sulfur importer, accounting for approximately 15.9% of my country’s sulfur imports. According to Chinese customs data, my country’s sulfur imports in 2022 will be 7.65 million tons, a year-on-year decrease of 10.3%. In the future, as my country’s sulfur recovery technology continues to upgrade and domestic sulfur supply capacity gradually increases, my country’s dependence on external sulfur is expected to further decrease.
