Description:

The presence of water vapors in the gas negatively influences the devices and communications of gas refinement and gas transport systems, as the hydrates are formed inside them. To prevent this, gas dehydration is the obligatory process conducted at GPP to prepare gas to the transportation via main pipeline or to processing.

Unit products:

Gas dried complying with IS 51.40-93 or complying with the requirements of the customer. The usage of special adsorbents allows removing methanol and other heavy hydrocarbons from gas.
