Lately, the 2500 Nm³/h Hydrogen Recovery from Trichlorosilane Tail Gas Plant of Ningxia Futai Material Technology Co., Ltd. was successfully put into operation at the first test run and passed the Owner's acceptance. DKT Energy undertook the process technology, engineering design, supply of some key equipment and commissioning guidance of this project.

DKT Energy’s domestic leading dechlorination technology at ambient temperature and special adsorbents are adopted to recover high-purity hydrogen, which helps Ningxia Futai to produce new white carbon black products in an environmentally friendly way, further reduce production costs and improve economic benefits.

The successful acceptance of the project is attributed to the meticulous work of each link, which indicates that DKT Energy has taken another solid step in the professional field, and it is also the best proof of DKT Energy's professional technical strength and project management ability. In the future, DKT Energy will take more challenges, pursue excellence and create new achievements!

DKT Energy’s self-developed technology is adopted:

Chlorosilane and Hydrogen Recovery from Polysilicon Tail Gas

Technical features and advantages:

- Advanced and mature technology, simple process flow, stable and reliable operation;

- The special adsorbent for chlorosilane has high separation coefficient and high chlorosilane recovery rate;

- The purity of recovered chloride and hydrogen is high, which can completely meet the production requirements of polysilicon plant;

- Low energy consumption and good economic benefits;

- The plant has a high degree of automation, which can realize remote monitoring and unattended operation;

- Less investment, shorter construction period and smaller land occupation compared with the low-temperature separation method.
