Advanced Drying of Chlorine/Chlorine Hydrogen, and Technology for Recovering Chlorosilanes and Hydrogen from Polysilicon Off-Gases

In the polysilicon production process, high-purity trichlorosilane is obtained through chemical means, and its synthesis requires the use of high-purity chlorine gas, hydrogen gas, and hydrogen chloride gas (with a water content of ≤10 ppm). Therefore, both commercial chlorine gas (containing 400–1,000 ppm of water) and synthesized hydrogen chloride (containing 1,000–3,000 ppm of water) must undergo thorough drying. In the chlor-alkali industry, dried chlorine gas is used as a raw material for chemical production.

Wet Oxidation Desulfurization Technology

Wet oxidation desulfurization involves the absorption of gaseous hydrogen sulfide by an alkaline solution to form sulfide compounds, followed by further oxidation of these sulfides in the liquid phase in the presence of a catalyst and an oxidant to produce sulfur foam. The sulfur foam is then separated and refined to obtain sulfur as the final product.

MDEA Desulfurization and Decarbonization Technology

MDEA desulfurization and decarbonization technology has been widely used in the energy and chemical industries over the past few decades as a highly selective, low-energy-consumption, and cost-effective process for the efficient removal of hydrogen sulfide and carbon dioxide from natural gas, synthesis gas, refinery gas, coal gas, and other feed streams.

Technology for Recovering and Treating Ammonia-Containing Tail Gas to Produce Concentrated Ammonia Solution

In the production processes of the energy and chemical industries as well as the semiconductor industry, certain gas streams—such as blast furnace gas and the exhaust gases from gallium nitride epitaxy—contain varying amounts of ammonia, necessitating the recovery and treatment of this ammonia.

Volatile Organic Compound (VOC) Treatment Technologies in Industrial Gases

In response to the characteristics of volatile organic compounds (VOCs) generated during the storage and loading/unloading of oil products and chemicals—namely high hydrocarbon concentrations, complex compositional profiles, and significant flow fluctuations—Dakote has developed an integrated condensation-plus-adsorption VOC recovery technology.
