Product Details
HCL SCRUBBER
Hcl gas is colorless, pervasive and corrosive, mostly emitted from process reactors, Hcl storage tanks while filling and laboratory. Hcl gas emits easily from aqueous solution of concentrated hcl at atmospheric temperature and diluted hcl at higher temperature. The high vapour pressure of hcl tends to emit the fumes.

HCL SCRUBBER
HCL Scrubber
Hcl gas
Hcl gas is colorless, pervasive and corrosive, mostly emitted from process reactors, Hcl storage tanks while filling and laboratory. Hcl gas emits easily from aqueous solution of concentrated hcl at atmospheric temperature and diluted hcl at higher temperature. The high vapour pressure of hcl tends to emit the fumes.
Toxicity of Hcl Fumes
- The concentrated hcl fumes are hazardous to the human health and environment
- The IDLH value of hcl is 50 ppm and Permissible Exposure Limit (PEL) is 5 ppm
Working principle
Hcl Scrubber works on principle of absorption technology. A column in which gas is passed at bottom and liquid is sprayed at opposite direction. Packing material is filled to bring the intimate contact between gas and liquid. There are two things happening here, providing cooling for exhaust gas and removing hcl gas from exhaust.
Apzem provides complete packages from start to end including water level controller using automated solenoid valve, pH controller with dosing system.
- Liquid to Gas (L/G) ratio: Liquid required to cover / wet gas passed through the column. It is determined based on pollutants solubility in (Henry’s law) and solvent.
- Flooding: If the liquid is not sprayed equally in the column, the will pass in one side of the column, this leads to inefficiency of scrubbing. Normally, 60 – 80 % of flooding will be considered as optimum design.
- Selection of packing material: Generally packing material helps to increase the surface area for mass transfer between gas and liquid. This surface area / mass transfer area varies based on the size, shape and material of construction. Smaller the size, higher the efficiency and higher the pressure drop, and vice versa. Improper selection of packing leads to the higher power consumption and fouling in operation, scale formation etc.
- Solvent selection: Normally, water is used to scrub the hcl fumes if the concentration is high, greater than 3000 ppm. This forms the diluted hcl solution, and it can be reused. However, it does not work for lower concentration. NaOH will be used as solvent to increase the absorption efficiency and to scrub continuously.
