TEG Biogas Drying

Biogas usually contains a large amount of water and is typically water-saturated. This water causes several problems for downstream processes and equipment, such as corrosion or freezing in pipelines at relatively high temperatures. Frames has developed a complete range of glycol-based dehydration solutions to handle the most demanding conditions. For biogas installations our team of engineering experts designs, builds, and commissions a complete drying solution to meet the gas demands of the downstream processes.

Glycol-based Gas Dehydration

Minimized energy and glycol consumption

Removing water vapor from gas is an integral part of our gas upgrading roots. The drying of upgraded biogas prior pipeline injection or direct use is a natural extension of these roots. Our glycol-based dehydration technology is capable of drying green gas or bio-methane below a typical dewpoint of -30ºC at 8 bar gas injection pressure, assuring full compliance with most existing regulations for gas injection of bio-methane in local natural grids.

Frames Glycol-based Gas Dehydration Systems use liquid desiccant technology to efficiently remove water from biogas and carbon dioxide. Building on more than 30 years of industry experience, our engineers are able to specify the best glycol system to fit your requirements and optimize field performance. The glycol gas drying is a continuous
process making it superior in performance and more compact then batch-wise operated solid bed dryers.

Our glycol-based dehydration systems include efficient, energy-saving technology such as plate and shell & tube heat exchangers. Moreover, a smart reflux section and the use of high capacity packing ensures very compact equipment and virtually no glycol losses.
