Anhydrous HCL Gas generation unit

UD Technologies is a leading manufacturer,Supplier and Exporter of  Anhydrous HCL Gas generation ( from Hydrochloric Acid) unit in Vadodara,Gujarat,India.

Dry HCl Gas Generator produces Hydrogen Chloride Gas from Hydrochloric acid .

Hydrogen Chloride Gas is used in

  • Hydro-chlorination reaction. This reaction uses HCl to Organic Chemical to form Water soluble Hydrogen chloride salts.
  • Hydro-chlorination of Rubber
  • Production of vinyl and alkyl chlorides
  • In the semiconductor industry, it is used to both etch semiconductor crystals

Generally, for Lab scale, Hydrogen Chloride gas makes available through cylinders. But for industrial production, it becomes very costly .In addition , during passing in the reactor; the chemist faces Operating problems

UD Technologies offer Dry HCl gas generator  from 10 kg/hr to 300 Kg/hr

With assistance from highly qualified and experienced professionals, UD Technologies manufacture and supply a huge range of  Anhydrous HCl Gas Generation Unit.

Our units are recognized for its indispensable features.

Due to wide demand in  numerous industries, Our team designs HCl gas generator systems using superior quality material and cutting edge technology.

Further, Our quality inspectors strictly inspect HCl gas generator system.

This unit also has use in  the production of  IPA HCl and Methanol-HCl for API Industries

Considering capacity ; UD technologies offer for three different routes.

  1. By Sulfuric Acid route
  2. By Boiling route
  3. By Calcium Chloride route

One can choose Dry HCl Gas generator through various routes depending on size,Effluent like 21% HCl re usability,cost and  Strictly near zero effluents

Similar Unit is also used for HCl Concentration for Feed HCl above Azeotropic Point

Dry HCL  Gas Generation Unit by Calcium Chloride Route

Hydrochloride gas is useful for Several Applications such as hydrochlorination of the Bulk drug to make product water soluble.

It also requires in the anhydrous state for critical reactions where moisture cannot be tolerated.

Calcium chloride route has cheapest in working cost due to little neutralization cost. Whereas in other routes, a large amount of  acid  generates whose neutralization cost and handling cost is much more

UD Technologies are Leading manufacturer and supplier for  HCL Gas Generation systems by Calcium chloride route

Principle:

Hydrochloric acid and water form a maximum boiling point azeotrope at 11O°C corresponding to a concentration of 20.24%; HCl.

By adding concentrated calcium chloride solution to commercial hydrochloric acid; azeotrope point is eliminated. As a result, the entire HCl becomes available for liberation by distillation.
HCl gas generation through Calcium Chloride Route is the most environmentally friendly technique .

PROCESS DESCRIPTION:

hcl gas generator cacl2
Anhydrous HCl Gas Generator

Metered quantities of HCl acid and CaCl2 solution pumps to stripping column. Due to this mixes in required quantities. Also, a steam heated re-boiler provided at the bottom  supplies heat to keep the solution hot.

The effluent from the bottom of the column is a dilute acidic calcium chloride solution. So, this solution concentrates to the desired concentration in an evaporator. After concentration, a concentrated solution recycles in Hydrogen chloride generator column.

The vapor leaving Hydrogen chloride Generator condenses stage wise with firstly, cooling water and secondly chilled brine as a coolant. Therefore this condensation helps to achieve dryness in  HCl Gas. However, Brine can be used for better results and lower consumption of Sulfuric Acid in Trap

For further drying, HCl gas passes through a mist eliminator and washes out in sulfuric acid. As a result, Gas is completely dry.

After that, Gas leaves to the point of consumption.

SALIENT FEATURES:

  • Designed Considering operation and maintenance problem
  • A proven design that is a combination of different MOC most suitable for application
  • Turn down ratio of 30%
  • Simple operation makes system operation and maintenance Friendly(Less Pump and Instrumentation)
  • ·Nearly zero Effluent system which makes payback period fast over other systems. This is due to Higher raw Material costs and handling and neutralization cost of Effluents in other routes
  • Supplied by an experienced team of Engineers in this field
