Regeneration Gas Heaters

Natural gas flowing from production wells or underground storage requires dehydration to protect the distribution system from corrosion and hydrate formation. In the commonly used solid desiccant absorption dehydration process, wet gas flows through a pressure vessel tower filled with solid desiccant. The moisture is absorbed on to the surface of the desiccant and the gas leaves the tower dry. When the desiccant is saturated with moisture, the gas flow is switched to another tower having dry desiccant. A regeneration gas heater is used to heat regeneration gas for drying out the desiccant in the wet tower. This process usually occurs cyclically or repetitively.
