Biogas Dehydration

Gas Dehydration is an essential step in the upgradation process as it reduces the bulk volume of the gas and allows for an efficient refining process. The gas also has to be dehydrated as moisture is considered an impurity in the process and could damage the molecular sieves and equipment downstream. Therefore, it is essential to choose the correct dehydration technology in order to ensure industrial grade dehydration without significantly increasing the operating cost of the overall system. AtmosPower is one of the few players in the industry that can offer desiccant based dehydration systems operating at extremely low pressure (< 1 Bar G) and yet offer product gas dew points as low as -80 C°. This high level of dehydration prevents any unforeseen moisture build up in the system or downstream pipelines and provides an extremely dry gas at the output. Gas dehydration also known as Gas dehumidification or gas drying is a major business segment by itself for AtmosPower and it also fits in perfectly with Atmos’s Turnkey Biogas Upgradation, Syngas Upgradation & Landfill gas upgradation solutions.

The desiccant based

gas dehydration systems

can help achieve the desired moisture and oil dew point based on the specific requirements of the process and end application of the product gas.

With over 40 years of experience in manufacturing gas upgradation systems, AtmosPower has become an expert in Air, Gas and Solvent Drying Technologies. Along with air applications, AtmosPower’s Dryers are capable of dealing with highly critical Gases & Solvents including:

Apart from the gases and solvents mentioned above, AtmosPower’s R&D department is capable of providing customized solutions for any other gas & solvent drying and dehydration requirements.
