1、 Hydrazine hydrate industry chain

Hydrazine, also known as hydrazine, is the simplest diamine, which can form stable hydrazine hydrate with water. Hydrazine hydrate is a colorless and transparent oily liquid with light ammonia smell. It has strong polarity, reducibility, alkalinity and hygroscopicity. It is an important chemical raw material and chemical raw material

The intermediate is often used in the pharmaceutical industry to produce drugs for anti tuberculosis and anti diabetes. It can be used in the pesticide industry to produce herbicides, plant growth regulators, fungicides, insecticides and rodenticides. It can be used in chemical industry to synthesize various kinds of foaming agents, deoxidizing and deoxidizing carbon dioxide cleaning agents for boiler and reactor, and is often used in the military industry to produce rocket propellants. Rubber additives and fuel cells.

2、 Analysis on the current situation of import and export of hydrazine hydrate in China

Driven by the growing demand in China, the scale of hydrazine hydrate industry continues to expand, and the external dependence of China's hydrazine hydrate market continues to decline. At this stage, China is one of the major exporters of hydrazine hydrate in the world. In 2019, China's exports of hydrazine hydrate surged to 10514.7 tons, a year-on-year increase of 84.8%; Influenced by COVID-19 in 2020, the number of hydrazine hydrate exported to China was 5091.45 tons, down 51.6% from the same period last year. The import volume was 183.81 tons, a year-on-year increase of 10.2%.

In terms of import and export amount, according to statistics, by 2020, the import amount of hydrazine hydrate in China was 591400 US dollars, a year-on-year decrease of 0.9%; The export amount was US $10.8312 million, a year-on-year decrease of 56.5%.

In terms of average import and export price, as of 2020, the average import and export price of hydrazine hydrate in China has shown a downward trend. In 2020, the average import price was US $3217.22/ton, a year-on-year decrease of 10%; The average export price was USD 2127.33/t, a year-on-year decrease of 10.2%.

3、 Analysis on competition pattern of hydrazine hydrate industry in China

At present, there are not many hydrazine hydrate production enterprises in China, mainly including Jiangxi lanhengda, Shandong Weifang Yaxing, Hebei Tangshan CHENHONG chemical, Shanxi Changzhi Huojia chemical, Sichuan Yibin Tianyuan, Xinjiang Xinren chemical, Ningxia Risheng fine chemical and Inner Mongolia Hanjin chemical. Among them, Ningxia Risheng fine chemical has the highest hydrazine hydrate production capacity, accounting for 43% of the production capacity of hydrazine hydrate production enterprises in China.

Yibin Tianyuan Group Co., Ltd. is the only listed enterprise producing hydrazine hydrate. The hydrazine hydrate produced by Tianyuan Co., Ltd. is recognized as a famous trademark in Sichuan Province; From the current situation of enterprise operation, the operating revenue of Tianyuan shares has been increasing since 2012-2019. As of the first three quarters of 2020, the operating revenue of Tianyuan shares was 15.8 billion yuan, a year-on-year decrease of 17.38%, and the net profit was 15 million yuan, a year-on-year decrease of 80.51%.

From the perspective of the production and sales of hydrazine hydrate products of Tianyuan Co., Ltd., the production and sales of hydrazine hydrate products of Tianyuan Co., Ltd. have increased continuously in recent years. As of 2019, the production of hydrazine hydrate of Tianyuan Co., Ltd. was 2.98 tons, a year-on-year increase of 4.9%; The sales volume was 3.08 tons, a year-on-year increase of 12.4%.

4、 Analysis of hydrazine hydrate production process

At present, there are four production processes of hydrazine hydrate: lacI method, urea oxidation method, ketone nitrogen method and dioxygen water method. Most of the foreign countries choose the relatively advanced ketone nitrogen method and dioxygen water method, while most of the domestic enterprises use the relatively backward urea method except a few enterprises use the ketone nitrogen method. The comparison of four hydrazine hydrate production processes is as follows:

Wastewater will be produced during the production of hydrazine hydrate. An enterprise producing hydrazine hydrate by urea method with an annual capacity of 12kt will produce about 3 * 105 cubic meters of wastewater every year. The wastewater produced in the process of producing hydrazine hydrate will inevitably contain a small amount of hydrazine hydrate, acetone, acetone nitrogen, salts, a small amount of biuret dissolved in the wastewater and ammonium ions produced by partially decomposed Azodicarbonamide. When urea method is adopted, the wastewater will also contain urea. These compounds are shown in the form of COD, ammonia nitrogen and salinity during wastewater monitoring, and have certain toxicity. If they enter the water body without effective treatment, they will cause harm to the environment.
