The "introduction and development of polysilicon by-product silicon tetrachloride cold hydrogenation technology" established and supported by Urumqi Science and Technology Bureau and undertaken by Xinte Energy Co.
, Ltd.
has recently passed the acceptance
of the expert group.
The project is based on the introduction of GT Solar International Co.
, Ltd.
technology from the United States, after digestion, absorption and research to develop the largest single set of fluidized bed cold hydrogenation production equipment
in China.
This technology solves the problems of silica powder transportation, radiant electric heating, slurry treatment, etc.
, and forms its own characteristic silicon tetrachloride recycling process
.
During the implementation period of the project, 9 national patents were declared, of which 4 were invention patents
.
The successful development of this technology will change the backward situation of polysilicon by-product treatment technology in China, solve the common problems in domestic polysilicon production, and at the same time save 44,244 tons of standard coal for enterprises every year, save 360 million kilowatt-hours of electricity, save 325 million yuan in production costs, and play an outstanding role
in energy saving, emission reduction and efficiency enhancement for enterprises.
