BIOGAS CLEANING
Biogas is a gas mixture formed primarily of CH4, C02, water vapour and traces of other components (H2S, siloxanes, NH3, hydrocarbons and others). In order for it to be used within the CHP system, its moisture content needs to be reduced and all harmful compounds must be removed to ensure the durability of the equipment involved in its use as a biofuel.
BIOGAS DRYING
This technology combines cooling and condensation techniques which allow an elimination efficiency of over 95% to be achieved, depending on the working temperature, while also offering low operating costs. This can include a recoverer-washer, which in addition to minimizing the energy needs of the operation, allows the biogas to be washed with its own condensates producing a partial reduction of H2S and NH3.
BIOGAS UPGRADING
CO2 removal and biomethane production. This is performed by chemical absorption. The biogas is washed with a suitable chemical solvent (alkanolamine) to remove up to 100% of CO2 from this stream, as well as possible traces of H2S that can be found in biogas. As a result of the process, a biogas stream with a high level of CH4, similar to natural gas is obtained.
FOAM REMOVAL
The removal of foam and solids from the biogas is accomplished through two different techniques. First directing the biogas stream into a baffle that is located in an oversized chamber. Secondly, the gas is subjected to an extended exposure of continuous water spray. As a result, the foam is broken down and removed through the drain located in the lower part of the equipment.
