Sodium hydrosulfide (NaHS) has a wide range of applications and the United States is the world’s largest consumer.

Sodium hydrosulfide is an inorganic compound with the chemical formula NaHS. It appears as a white crystalline powder, has a pungent odor, is easily deliquescent, and is easily soluble in water and alcohol. The aqueous solution is strongly alkaline. Sodium hydrosulfide industrial products are generally liquid, with an orange or yellow liquid appearance and a bitter taste.

There are various production methods for sodium hydrogen sulfide, which can be prepared by caustic soda absorption method, sodium alkoxide hydrogen sulfide reaction method, sodium hydroxide absorption method, etc. Among them, the sodium hydroxide absorption method is one of the main production methods of sodium hydrosulfide at present. It refers to the method of using sodium hydroxide solution as raw material and using an absorber to absorb hydrogen sulfide gas to obtain sodium hydrosulfide.

Sodium hydrosulfide has a wide range of applications. The main application areas include chemistry, medicine, pesticides, dyes, leather production, mining industry, food processing, wastewater treatment, etc. Specifically, in the chemical field, sodium hydrosulfide can be used as a reducing agent to reduce metal ions and other compounds, and as a vulcanizing agent in paper and rubber production scenarios; in the pharmaceutical field, it is used as a diuretic, analgesic, etc. Raw materials required for drug production; in the field of food processing, it can be used in the production of food additives such as preservatives and deoxidizers, as well as seasonings such as MSG and soy sauce; in the field of dyes, it is the raw material for various sulfur dyes; in the mining industry, it Mainly used in copper ore beneficiation scenarios.

According to the “China Sodium Hydrosulfide (NaHS) Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center shows that benefiting from the rapid development of application fields, the global sodium hydrosulfide market continues to expand. The global sodium hydrosulfide market size will be approximately US$1.55 billion in 2022, a year-on-year growth of 3.2%. From the perspective of geographical distribution, the United States is currently the major consumer of sodium hydrosulfide in the world, with a market share of about 45%. The main reason is that the United States is the world’s largest pulp producer. In 2022, U.S. pulp production will exceed 50 million tons. The sulfate method using sodium as raw material is one of the main methods of pulp production in the United States; followed by China, which accounts for more than 20% of the market.

Globally, sodium hydrosulfide production companies mainly include international companies such as Genesis Energy LP in the United States, Nouryon in the Netherlands, Sankyo Chemicals in Japan, Chemical Products Corporation in the United States, and Tessenderlo in Belgium, as well as Vantone Petrochemical, Yamei Technology, Xinle Chemical, Minyu Chemical, Yifeng Biochemical Environmental Protection, Fengshi Chemical, Xinke Environmental Protection, Taiji Petrochemical, Chengyuan Chemical and other Chinese companies.

Industry analysts said that sodium hydrosulfide is an important chemical raw material and pharmaceutical and pesticide intermediate, and can be widely used in chemical, There is broad market demand in water treatment, food, medicine, papermaking, pesticides and other fields. Today, the United States and China are the major consumers of sodium hydrosulfide in the world. my country is also the major producer of sodium hydrosulfide in the world through the increasing number of enterprises and the continuous release of production capacity. At present, my country’s sodium hydrosulfide production technology has become mature, and various high-end products such as high-purity sodium hydrosulfide, anhydrous sodium thiocyanide, and crystalline sodium hydrosulfide have been mass-produced.
