Biogas Purification Solutions

Babcock & Wilcox MEGTEC (B&W MEGTEC) offers biogas

purification equipment for removal of particulate, H2S,

CO2, H2O and siloxanes from your digester, wastewater

treatment, landfill or other biogas stream.

B&W MEGTEC’s skid-mounted systems include a high-

pressure, packed bed, chemical-free water scrubber

and air stripper for removal of CO2 and H2S with

minimal methane loss. The system can achieve up to

98% methane content.

To reduce water usage, the wash water system is

regenerative, as opposed to a single-pass system.

Moisture removal is accomplished via twin column

regenerating desiccant chambers. To minimize energy

usage, heat from the system can be recovered and

reused through a closed loop, glycol heat coil system.

Siloxane removal is accomplished by a vertical

activated carbon vessel (if required).

Systems include 316 stainless steel knockout pots and

flash drum with demister pads for raw gas moisture

removal.

Gas compression is achieved with a two-stage, twin

rotary screw compressor constructed from 304

stainless steel.

Fresh water metering and circulation pumps are

constructed of stainless steel to prevent corrosion.

All system components are factory assembled and

tested to the fullest extent possible to reduce field

installation and start-up time.

Should treatment of the tail gas be required, B&W

MEGTEC can also provide a flameless, regenerative

oxidizer.
