Resurrection of Independent Cold Hydrogenation Technology——The Development and Application of Hualu's Fifth Generation Cold Hydrogenation Technology and Equipment

At present, the 10,000-ton/year high-purity polysilicon technical transformation project of Xinjiang Xinte Energy Co.

The cold hydrogenation unit is the core unit of polysilicon production, which can convert silicon tetrachloride into trichlorosilane, the raw material for polysilicon production

As a leading enterprise in domestic polysilicon technology research and development and engineering design, Hualu has innovated, explored and iteratively optimized in the field of polysilicon technology development for more than 10 years, changing the passive situation that core technology is controlled by others

As early as 2006, relying on the accumulated experience and technical advantages in the synthesis of organic silicon and trichlorosilane, Hualu successfully developed polysilicon cold hydrogenation technology

"The first-generation cold hydrogenation plant, although the annual processing capacity of silicon tetrachloride is only 10,000 tons, has an important milestone significance and fills a number of technological gaps in the field of polysilicon production in China

According to reports, the diameter of the first-generation cold hydrogenation device reactor was 0.

The development of the reactor is not a smooth road, facing countless attempts, failures, and innovations.

"If the first generation of cold hydrogenation technology solves the problem of yes and no, then every subsequent technological progress, we focus on system optimization and improvement, reduce energy consumption, tap potential and increase efficiency, actively solve customers' difficulties and pain points, and lead the way.

According to reports, Hualu Company is responsible for the engineering design of Xinjiang Xinte polysilicon project, which for the first time has increased the silicon tetrachloride processing capacity of a single cold hydrogenation unit to the world's largest 350,000 tons/year

During the "14th Five-Year Plan" period, Hualu Company clarified the strategic positioning of "focusing on the four major business sectors of engineering, R&D, industry and equipment, and creating an overall solution provider for the realization of the 'double carbon' goal", among which equipment has become a key component of transformation and development.

In recent years, the photovoltaic industry has driven the rapid development of the polysilicon industry

At present, Hualu's fifth-generation cold hydrogenation technology equipment has also been recognized by the industry
