Dehydration of Natural Gas, water in CNG CNG fueling
This water vapor must be removed from the gas stream in order to prevent the formation of solid ice like crystals called hydrates. Hydrates can block pipelines, valves and other process equipment. The dehydration of natural gas must begin at the source of the gas in order to protect the transmission system.

Dehydration of Natural Gas is the removal of the water that is associated with natural gases in vapor form. The natural gas industry has recognized that dehydration is
CNG Filling Stations Products Compex
Natural gas from a pipeline is cleaned from mechanical impurities by filter system and then goes to a compressor, where it's compressed. After condensed moisture has been separated in a dehydration unit, gas is pumped into refillable gas storage under the pressure of 20 25 MP. Treated gas is used for fuel vehicles using CNG dispensers.

Natural Gas Dehydration Unit Dehydration of Natural Gas
Membrane Dehydration. In GENERON ® membrane gas dehydration systems, the feed gas is filtered to remove any trapped liquids and aerosols. The gas then enters the GENERON ® membrane filters, where the H 2 O, CO 2 and H 2 S permeate through the membrane. The non permeated gas, mainly CH 4, remains at process pressure and becomes the product gas.. Membrane Dehydration
CNG Mother Station Compressor
A mother station will always be located near a natural gas pipeline. Mobile storage allows transportation of natural gas to a site that does not have access to a natural gas pipeline.Typical applications where mother stations are used are to supply gas to: daughter CNG stations, industries and city gas distribution systems.

NATURAL GAS DEHYDRATION WITH TRIETHYLENE
This work studies the dehydration of natural gas using Triethylene Glycol (TEG)” as the dehydrating agent or absorbent to examine the water content of the natural gas stream when the dehydrating agent and the gas flows in counter current manner in an absorption column and to determine hydrate formation temperature and prevent its occurrence.
Dehydration of Natural Gas, water in CNG CNG fueling
This statement, now known as Dalton’s Law of Partial Pressures, allows us to compute the maximum volume of water vapor that natural gas can hold for a given temperature and pressure. The wet inlet gas temperature and supply pressures are the most important factors in the accurate design of a gas dehydration system.
Natural Gas Dehydrators & Dryers
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.
