Carryover Problem

Gas exiting CO2 absorbers carries amine mist and droplets from packing, foam carryover, or high gas velocities. Lost amine costs money and contaminates downstream systems. Outlet separators recover solution returning it to process preventing waste and equipment problems.

Separator Design

Vertical vessel with gas inlet from absorber top, mist eliminator coalescing fine droplets, drain section collecting recovered amine, clean gas outlet, and liquid return line to absorber or circulation system. Compact design mounts directly on absorber outlet.

Mist Elimination

Wire mesh pads capture droplets above 3-10 microns. Vane packs handle higher liquid loads. Multiple stages ensure complete recovery. Separation efficiency 95-99% prevents amine loss to atmosphere or downstream equipment.

Operating Pressure

Matches absorber overhead pressure typically 5-150 psig depending on application. Low pressure drop preserves gas flow. Design accommodates pressure variations during load changes.

Material Selection

Stainless steel construction resists amine corrosion. Mist eliminator materials withstand continuous amine exposure. Design accommodates operating temperature typically 35-50C at absorber outlet.

Amine Recovery

Recovered solution drains by gravity back to absorber or circulation system. Level control manages inventory. Collected amine maintains system balance reducing makeup requirements. Recovery reduces operating costs significantly.

Applications

Power plant CO2 capture systems, natural gas CO2 removal, hydrogen production with carbon capture, industrial gas sweetening, and any absorption process where solvent carryover occurs. Critical for economic carbon capture operation.

Gas Quality

Clean outlet gas meets specifications for compression, sales, or atmospheric discharge. Prevents amine contamination of compressors or pipelines. Eliminates visible plumes from amine aerosols. Meets environmental discharge requirements.

Performance Benefits

Reduces amine makeup costs by recovering carryover. Protects downstream equipment from solvent damage. Prevents environmental releases. Simple passive separation requires minimal maintenance. Fast payback from solvent savings.

Installation

Mounts on absorber vessel or adjacent structure. Drain line gravity-feeds to absorber. Gas outlet connects to downstream system. Minimal plot space. Easy retrofit on existing absorbers showing carryover problems.

Construction Standards

Design per applicable codes for pressure and temperature. Materials suitable for amine service. Mist eliminator sized for gas flow and liquid loading. Complete documentation with separation efficiency calculations.
