HCl Hydrochloride Gas Generator-Calcium Chloride Route
Method Of Hcl Gas Generator CaCl2 RouteSeveral methods have been adopted by industries for HCL Gas Generator. But generation by Sulphuric Acid Route and Boiling Route are commonly practiced. We offer Calcium Chloride Route for HCL Gas Generator.Hydrochloric acid and water form a maximum boiling point azeotrope at 11OC corresponding to a concentration of 20.24%; HCl. By adding concentrated CaCl2 solution to commercial hydrochloric acid; azeotrope point is eliminated and. the entire HCl becomes available for liberation by distillation.Anhydrous HCl gas generation through Calcium Chloride Route is the most environmental friendly technique.
Process DescriptionThe above principle- is achieved in practice by feeding metered quantities of commercial HCl and CaCl2 -solution to a stripping column with a steam heated re-boiler at the bottom. The effluent from the bottom of the column is a dilute acidic calcium chloride solution which is concentrated to desired Concentration in a evaporator and re-used. The vapor leaving is condensed stage wise with cooling water and chilled brine as a coolant. The relatively dry gas passes through a mist eliminator and to the point of consumption.

Aqueous Hydrochloric acid is a mixture of Hydrochloride and Water. As Hydrochloride is highly soluble in water, Aq, Hydrochloric acid at 25 0c, available in strength up to 30 % Hydrochloric acid Large Quantity of Hydrochloric acid is used in Metal Processing industry, where dilute acid is generated. It is necessary to recycle Hydrochloric acid to cut costs due to neutralization and environment.UD technologies offer solutions for this problem and offer Hydrochloric acid Concentration plants. We choose appropriate technology and Material of Construction depending on capacity Hydrogen chloride/water displays a maximum azeotrope at a boiling temperature of 108.6°C, for a system pressure of 1 bar and an HCl concentration of 20.2wt%.
If the acid concentration is lower than the azeotrope mixture, the acid can be concentrated only up to the azeotrope point. Further concentration needs special procedures.
We have considered the most economical contemporary technology “Azeotropic distillation & Absorption Technology”. This is an economical technology. The azeotrope point is suppressed as best as possible and increases the relative volatility of HCl. The relative volatility may be impacted by the change of the activity coefficients. This is achieved by the addition of a third ingredient, which knocks out water and displays strong hygroscopic properties. Conc. HCL & HCl gas is produced at the head of the Azeotropic distillation and Absorption column depending upon the choice of an appropriate extraction agent. In the column, the extraction agent is diluted with water, which is extracted in a selective fashion from the inflowing mixture. Subsequently, the extractive agent is recycled and concentrated and fed into the Azeotrope Distillation process. Sulphuric acid and aqueous solutions of CaCl2 are appropriate extraction agents for the concentration of hydrochloric acid.

Features:
Concentration of Weak Sulphuric Acid from 20 % to 70 %
UD Technologies offer sulphuric Acid concentration plants from 20% to 70% .
Sulfuric acid is one of the worlds most widely used chemicals and finds numerous applications as the production of fertilizers, explosives, plastic as e.g. polyurethanes, esterification of intermediates, dyes and also the iron and steel industries.
In most chemical processes contamination and dilution of concentrated sulfuric acid occurs producing huge waste streams of contaminated spent sulfuric acid.
70% Sulphuric acid can be reused .Also Concentration up to 70% , during evaporation, Sulphuric acid vapors evolved is nearly nil.Concentrating sulfuric acid from 20 to 70wt% involves evaporation of large amount of water out of the sulfuric acid. Single- or multi stage natural circulation evaporators, Themosyohon or Forced circulation evaporators in Multi stage are used to minimize the required amount of heating steam. Multi stage evaporators uses vapor arising from previous or next evaporator using boiling point difference and pressure difference.
The number of stages and the type of heating system for each stage are governed by the concentration of the waste acid and the available heating media. Account must also be taken to the behavior of the acid during the concentration process such as the generation of gases possibly leading to foams and the precipitation or evaporation of products present in the waste sulfuric acid.

Advantages of the product
Hydrogen chloride is produced as a by-product or waste gas by a variety of processes like chlorination of Organic chemicals within the process industries. In many countries there are strict maximum emission levels for hydrogen chloride which mean that it must be removed from waste gas streams. This may be done simply by scrubbing it out of the waste gas, or where the quantities are large enough, by absorbing it to produce a hydrochloric acid product.
Hydrogen chloride has a great affinity for water and the absorption can be easily accomplished as long as a suitable method is found to contact the gas and the water. The absorption of hydrogen chloride into water causes a great deal of heat to be evolved which has to be removed from the system. The theoretical maximum concentration achievable is dependent on the temperature and the partial pressure of HCI in the exhaust gas entering the plant.
The most appropriate HCI absorption process for any particular application depends on the nature of the feedstock and on the product required. The three basic types are batch-wise operated HCI scrubbers or continuously operated adiabatic and isothermal absorbers.
Hydrogen chloride and hydrochloric acid are very corrosive materials and will attack many materials of construction commonly used in the chemical process industries. Borosilicate glass is the ideal material of construction, being suitable for handling hydrogen chloride gas, hydrochloric acid, and any impurities present with the exception of hydrofluoric acidHydrogen chloride eventually generated in reaction along with SO2, Unreacted chlorine or organic vapors.T o absorb Hydrogen chloride with such additional chemicals, need s different designs and required expertise
The Adiabatic absorber is the simplest form of HCl absorber, which can be operated continuously. Under the normal operating procedure, Adiabatic Hydrogen Chloride Absorber produces 30 % HCl. Adiabatic Absorber is a vertically mounted Packed Column. The standard configuration of the adiabatic absorber consists of a suitable Glass Packed Column with internals, coil type condenser & cooler with the necessary drain outlet for the acid. The Hydrogen Chloride Gas enters at the bottom of the column & Water flows from the top of the column & flows down through the column.
Heat generated by the dilution of Hydrochloric acid gas with water. It vaporizes @30% water and other non-soluble components of the gas stream. Condensed stream together with make up water is returned to the packed tower and discharged from the bottom of the column after cooling by cooling water.
Falling Film Absorber Capacity:10 Kg/hr to 900 Kg/Hr Incoming 100%HCl gas Process Description Hydrogen Chloride gas is produced from the variety of process industries & mainly from chlorination operation. This must be scrubbed before venting to the atmosphere. Hydrogen chloride has a great affinity of water and easily absorbed in water. The absorption of Hydrogen Chloride gas in to water cause large amount of heat, due to exothermicity which has to be removed by means of suitable device. The remaining un-absorbed gas along with other inserts from the bottom of the absorber is entering in to Secondary Process water is circulated through Secondary Scrubber to absorb the HCl gas and form dilute acid. The advantage of providing Tail Scrubber is to get scrubbed Unscubbed 5% gases. This dilute acid is circulated through Falling Film Absorber to absorb HCl gas as explained above.
Salient Features : High absorption efficiency. High acid concentration achievable. Safe Operation due to low isothermal temperature. Handle a wide range of gas loading with minimum liquid flow rates to maintain full tube wetting. Variation in Hydrogen Chloride Gas flow rates or Composition causes no operation problem.
