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 great affinity of water and easily absorbed in water. The absorption of Hydrogen Chloride gas in to water cause large amount of heat, which has to be removed by means of suitable device.
The falling film absorber is the simplest form of HCL absorber, HCL Gas Absorber which can be operated continuously. Falling Film Absorber is a vertically mounted shell and tube heat exchanger. The standard configuration of the falling film absorber consists of a suitable shell and tube heat exchanger with the necessary drain outlet for the acid. The Hydrogen Chloride Gas enters at the top of the absorber and flows concurrently with water/Dilute HCL.

Process Description :Cooling Water is circulated through shell side of the Falling Film absorber to absorb the heat generated by the dilution of Hydrochloric acid gas with water. Due to its unique design and construction, the heat of absorption is efficiently removed at the zone of absorption, thereby making the absorber extra efficient. Thus the higher concentration of acid is produced due to low absorbing temperature.

Capacity Range : 10Kg/hr. to 900 Kg/hr.
Available up to 600mm dia.

Salient Features :

• High absorption efficiency.
• High acid concentration achievable.
• Low outlet temperature.
• Easy operation and maintenance.
• Safe Operation due to low isothermal temperature.
• Handle a wide range of gas loading with minimum liquid flow rates to maintain full tube wetting.
• All the wetted parts of the falling film absorber are corrosion resistant to all the aggressive gases even at elevated temperatures.
• Variation in Hydrogen Chloride Gas flow rates or Composition causes no operation problem.

The column is constructed with a series of packed sections, a gas introduction point below that, a condenser on the top, and a cooler at the bottom. Make water is sprayed from the top and acid is collected from the bottom.
HCL absorption columns are available in 80DN to 300DN diameter (for the gas rate 10 Kgs/hr to 300 Kgs/hr approx).

The acid should be added slowly to cold water to limit the buildup of heat. If water is added to the concentrated acid, enough heat can be released at once to boil the water and spatter the acid. Sulphuric Acid reacts with water to form hydrates with distinct properties.

The feed is acidified with 30% HCI acid and acidified feed is fed to the scrubber by pump to Scrub uncondensed chlorine from Vent Condenser and return back to the reaction column. In some cases the part feed is preheated using effluent from the reaction column prior to the entry of reaction column and part feed is fed to the scrubber to conserve energy. Chlorine and Steam are also fed to the reaction Column.
In the reaction column the feed is reacted with chlorine gas & bromine is liberated Instantly. This liberated bromine is stripped out of the solution by live steam. The bromine and water vapour stream leaves the top of the column and enters the condenser. Condensate falls into the Phase Separator where it forms two phases, the light aqueous phase (Water) being returned to the Column , while the heavy phase(Bromine) being feed the purification column. Industrial Bromine Recovery Plant, Bromine Recovery Plant, Cooling Water & Chilled Water is used as cooling media in heat exchanger provided at the top of the column to condense water vapour & Bromine.
Purification of the Bromine is achieved by distillation. Heat being introduced into the column through the reboiler. Bromine and Chlorine vapour leave the top of the Column and enter the Condenser .The Bromine gets condensed in the Condenser and falls back into the column while uncondensed chlorine vapour along with traces of Bromine escapes from the Condenser and enter into the Vent Condenser, where remaining Bromine gets condensed and back to the crude Bromine receiver. Pure bromine is cooled in a product cooler and goes to Product receivers. Guard condenser is also provided at the top of the receiver to prevent escape of bromine. Bromine is then collected in glass bottles.

• The units are available in vessel sizes of 20, 50, 100, 200 & 300 Ltr. and is suitable for operation under atmospheric pressure and full vacuum.

Specifications :

• HCL absorption columns are used for absorption of Hydrochloric gas, which statutorily are not permitted to vent into the atmosphere, and to produce the HCl acid.
• The column is constructed with a series of packed sections, a gas introduction point below that, a condenser on the top, and a cooler at the bottom. Make water is sprayed from the top and acid is collected from the bottom.
• HCL absorption columns are available in 80DN to 300DN diameter (for the gas rate 10 Kgs/hr to 300 Kgs/hr approx).
• HCl gas can be economically absorbed forming Hydrochloric acid of 30% (w/w) concentration which can be re-used in the main process. Thus this absorption is a pollution abatement as well as a recovery process.

The absorption can be done by two different methods :

• Adiabatic Absorption: This method is suitable when the inerts like air, phenolic compounds etc are substantial.
• Isothermal Absorption: This method is suitable when inerts like air phenolic compounds, etc ar negligible.

Description :

• This is essentially a compact batch-type fractional distillation unit in which the re-boiler consists of a vessel mounted in a heating bath and with a packed column above. The vapors from top is condensed and can be refluxed as per requirement.
• The top product is sub-cooled and collected in receivers. The bottom product is finally drained from the re-boiler through a drain valve. The units are available in vessel sizes of 20, 50, 100 & 200L, and 300Ltr. is suitable for operation under atmospheric pressure and full vacuum.

Any kind of distilling Unit normally includes a heating source such as a hot plate, heating mantle, or Bunsen burner to heat the mixture. Ring stands support the components, which are clamped in place on the stand by clamps or clips. A thermometer provides temperature readings and fits into the top of the distilling adapter. Tubing supplies water to the condenser.
