Customized solutions for NCG handling

Customized solutions for NCG handling

Valmet offers collection and handling systems both for Concentrated Non Condensable Gas (CNCG) as well as for Diluted Non Condensable Gas (DNCG). Our solutions provide you with an extremely high oxidation rate and superior system availability, resulting in additional savings through reduced maintenance time and increased production time.

A further benefit is the recovery of sulfur. Sulfur can be recovered back into the pulp mill’s chemical cycle in a recovery boiler or from the flue gases as sodium bisulfite or SO2 water. If required, lime scrubbing can be used to completely remove excess sulfur from the chemical balance.

In addition to CNCG and DNCG systems, Valmet’s product portfolio also includes Stripper Off Gas (SOG) Handling Systems and Recovery Boiler Dissolving Tank Vent Gas Handling Systems (DTVGS).
