HAS.CO packed bed scrubbers are multipurpose, reliable systems that serve the widest variety of processes. They are used and specified worldwide.

HAS.CO packed scrubbers are highly recommended for the efficient removal of inorganic gases, odors and fumes, and are particularly appropriate where gas streams have extreme ph.

Optimum system performance is achieved with systems that combine intimate gas/liquid mixing and low pressure drop.

Design option:

Single-Stage Vertical Flow:
These units are applied to inorganic scrubbing .This includes a multitude of chemical processes, metal finishing and Semiconductor applications. This also includes certain odor control systems (such as light inputs of ammonia or Sulfur-based compounds) that are accommodated with a single-stage process.

Two-Stage Vertical Flow:
These systems use two independent columns, operating in series. Columns can operate with identical chemistry, or more typically, use two different chemical processes. An example is ammonia combined with other acids, which requires one stage for primary removal using sulfuric acid, and a second stage operating as a caustic scrubber.
This design can be used in many other applications that require dual chemistries to destroy contaminants.

Multi-Stage Scrubbers (NOx):
In this equipment design, HSA includes three or more scrubber stages.
This design, which handles NOx, (NO+NO2) in any ratio. The primary application of this the removal of NOx from gas streams where other contaminants co-mingle with NOx.

HAS.CO manufactures wet scrubbers for flow volumes from 1,000 m³ to 200,000 m³ per hour.

As standard, we equip our round wet scrubbers with three different systems to discharge sludge. We can, however, also design special solution
