Natural Gas Dehydration
The purpose of natural gas dehydration units (also called natural gas dehydrators) is to remove water from natural gas and natural gas liquids. When produced from a reservoir, natural gas usually contains a large amount of water and is typically completely saturated or at the water dew point.
This water can cause several problems for downstream processes and equipment. At low temperatures, the water can either freeze in piping or, as is more commonly the case, form hydrates with CO2 and hydrocarbons (mainly methane hydrates). Depending on composition, these hydrates can form at relatively high temperatures plugging equipment and piping. (Source: Wikipedia).
AVP also supplies filters and desiccants for natural gas dryers as well as a single-tower pipeline dryer for drying landfill and digester gas.
Natural Gas Dehydrators (Dryers)
Single-Tower Deliquescent Pipeline Dryers
The Van Gas Technologies PLD is a single-tower deliquescent dryer which offers a simple and economical solution for gas dehydration. The dryer vessel has a large claim area, where the gas enters and liquids are separated and collected. The gas then flows up through the deliquescent desiccant tablets, which slowly dissolve as they remove moisture vapor from the gas. More »
