Case Studies

Three Stage Scrubber System for Wastewater Treatment Plant

Air Chem designed Turnkey system which included specified scrubber, fan, pH and ORP control system, skid and all ducting for the project.    

The System is capable of treating 500 ft3/min of air at an inlet concentration of 20 ppm H2S with a scrubbing liquid of NaOH and NaOCl.

Achieved a removal efficiency of 99.99%, with only one stage, well above the requirement

Horizontal Scrubbers for Ammonia Removal

Air Chem designed Horizontal Scrubber for Ammonia Removal, these Scrubbers processed over 50,000 ft3/min of air with inlet concentrations in excess of 100 ppm

Process 7000 ft3/min using only water as the scrubbing liquid

The System achieved over 98% removal efficiency

Stripping Towers for Gorund Water Contamination Removal

Air Chem designed a four-stripper system to separate the 7,800 gallons per minute into four streams of 1950 gpm and achieved an air to water ratio of 60:1 to ensure high removal efficiency

Featuring FRP fan with a 100HP motor, a sound enclosure, and a dual carbon system

Three Stages Unit Solution for Sewage Odor Problem

Air Chem came up with the design of three (3) stages scrubber for 4,000 CFM at 22” WC

Scrubbing liquid is composed of two chemicals, NaOH & NaOCl, removal efficiency of the unit is 99%+ on the H2S gas

Lower pressure drop required a less powerful fan resulting in a 50% savings in operations costs

Single Stage NOx Vertical Scrubber System

Air Chem engineered a vertical single stage NOx scrubber system with a quenching stage.

The pre-quench unit lower the air stream temperature to a maximum 140 degrees Fahrenheit

Process 3000 ft3/min with inlet NOx concentrations of up to 20,000 ppm with removal efficiencies of at least 90%

This unit was packed with 3.5” Lantac high performance packing, 10 ft diameter, and 40 ft high only allowed two (2) minutes dwell time
