Except chemical equipments for industrial corrosion resistant, we are in position to offer a special chemical process know-how systems such as hydrochloric acid synthesis unit, production of HCl gas from hydrochloric acid absorption, exhaust HCl gas absorption unit, Zirconium oxychloride evaporator of outside circulation, acid recovery from metal pickling...

Synthesis of hydrogen chloride by burning hydrogen gas and chlorine gas in graphite HCl acid synthesis equipment has proved to be an economical and reliable operation. This is true particularly in those processes where chlorine gas is produced as a by-product or where hydrogen chloride or hydrochloric acid is required for on-site use. Typical uses occur in brine electrolysis, vinyl chloride manufacture, paper and pulp production and various metallurgical processes

The absorption of hydrogen chloride in water or dilute hydrochloric acid is a central operation in the production of hydrochloric acid. However, this technique is also often used for cleaning waste gases or by-product gas from chemical production plants or waste Incinerator such as Mann-Heim Process potassium sulfate, chloroacetic acid, chlorinated paraffin, which statutorily are not permitted to vent into the atmosphere, and to produce the HCl acid.

With its outstanding heat transfer Properties, Graphite Heat exchanger can be used as an evaporator for evaporating and concentrating Zirconium oxychloride and other chemical. 

High Purity HCl Gas is produced by distillation of hydrochloric acid solutions with a concentration of 25 - 35 % under pressure in a desorption system.

With evaporation and Membrane concentration process, Steel Spent Acid can be recovered to >15% Hydrochloric Acid or 32% Hydrochloric Acid. By-product Solid Ferrous chloride or Ferric chloride can be used for water treatment.
