Molecular Sieve Drying System
Hydrochloric Acid Desorption & Calcium Chloride Concentration System
Hydrochloric Acid Evaporation & Concentration System
Sulfuric Acid & Material Concentration System
Application Background Sulfuric acid is widely adopted as raw material in smelting, titanium dioxide and other industries, and dilute sulfuric acid with low concentration is generated after reaction. Evaporation concentration
Titanium Dioxide Waste Acid Treatment System
Application Background China’s total titanium dioxide production capacity reaches 3.5 million tons, and the sulfate process dominates domestic TiO₂ manufacturing. Large volumes of waste acid and wastewater are generated during
Sulfuric Acid Dilution and Cooling System
Application Background Sulfuric acid is a versatile industrial raw material. Commercially supplied sulfuric acid is normally 98% concentrated sulfuric acid, which generally requires dilution to different concentrations to satisfy various
Two-in-One Hydrogen Chloride Synthesis System
The two-in-one hydrogen chloride synthesis furnace mainly integrates the synthesis section and cooling section. Hydrogen and chlorine are mixed and combusted to produce hydrogen chloride gas. After cooling, the gas
Three-in-One Hydrochloric Acid Synthesis System
The three-in-one hydrochloric acid synthesis furnace is mainly used for hydrochloric acid production. It integrates the synthesis section, cooling section and absorption section as an integrated unit, yet a supporting
Conventional Hydrochloric Acid Desorption System
Heating hydrochloric acid with steam to desorb hydrogen chloride gas is another widely adopted method for HCl production, apart from the synthesis reaction of hydrogen and chlorine. In the process,
Hydrochloric Acid Extractive Distillation System
This system is applicable to hydrochloric acid of any concentration. An extractant calcium chloride (CaCl₂) is added into the acid to break the chemical equilibrium, so that hydrogen chloride gas
Differential Pressure Distillation System
This process produces hydrogen chloride gas by taking advantage of the property that the azeotropic concentration of hydrochloric acid varies with pressure. Hydrochloric acid is concentrated under negative pressure, and
Waste Acid Treatment Evaporation System
Evaporation Evaporation technology ranks among the primary core technologies widely applied in the environmental protection industry. Evaporation systems are commonly used to remove impurities from waste acid. Hydrogen chloride and
HCl Drying System
Our molecular sieve drying system has been proven to be the ideal unit for hydrogen chloride gas drying. Three adsorption towers operate alternately in adsorption and regeneration cycles to achieve
