Glycol dehydrators are used in the natural gas industry to remove water from natural gas to prevent the formation of hydrates, corrosion and maximize pipeline efficiency. Using amine treatment to remove acid gases results in water-saturated gas that must be dehydrated before entering the pipeline. Water vapor is one of the most common impurities found in a natural gas stream. We custom design and fabricate glycol regeneration and dehydration packages to remove water from natural gas and recondition glycol used for processes such as hydrate inhibition and gas dehydration. In this example, the water dewpoint spec for the dry gas is -20C (- 4F) at 6200 kPa (900 psia). With stripping gas, dew point depressions up to 150F are .

High-energy recovery and low-glycol loss is achieved by our dehydration packages and modules, which are compact, low in weight, and small in footprint. TEG dehydration units lower the water dew point, allowing the water vapor to condense to a liquid at a lower temperature. Escher Process Modules has built up a worldwide reputation in the oil and gas industry for the design, fabrication, installation and commissioning of Oil & Gas Treatment Systems. Mrs. Snow-McGregor has been active in the gas processing / midstream industry for many years and is on the Board of Directors for the GPSA. If structured packing is used here it should be designed for a maximum Fs of 2.8. This is why filters are typically used to remove the impurities. Raw natural gas or wet gas can have varying degrees of water content, aerosols, and droplet sizes, so our TEG gas dehydration system reduces the water dewpoint and removes solids from the gas.

Once in hand, share this with everyone on every crew and develop a plan to optimize the equipment. TEG dehydration is the most commonly used natural gas dehydration process, often used in compressor stations to prevent hydrates from forming in gathering systems, and in-plant facilities to meet a pipeline water dew point specification. What Is a TEG Gas Dehydration Unit? Flow diagram of a typical Schlumberger glycol dehydration unit. 9, 10 The dehydration process with TEG consists of two major steps: absorption of water in wet gas through absorption column and desorption. Triethylene Glycol (TEG) Dehydration units remove water vapor from natural gas streams. The Frames TEG package also included a lift gas contactor and gas/glycol heat exchangers. This water causes several problems for downstream processes and equipment, such as corrosion or freezing in pipelines at relatively high temperatures. These units range in size from 1.0 mmscfd (28.3 103m3/d) to over 120 mmscfd (3,398 103m3/d). A glycol dehydration unit is comprised of two major components: the contact tower, and the regeneration skid.

This process has already been implemented and is industrially proven on CO 2 dehydration applications even in the presence of other acid gases such as H 2 S. Proven instructional design methodology and advanced web technology provide effective knowledge transfer for learners. Water escapes as steam, and the purified glycol returns to the tower where it again contacts wet gas. TEG acts as a desiccant to absorb water vapor from the natural gas stream. TEG comes out of the surge tank at 375 degrees and as seen here, has burned the paint off the piping. We have manufactured TEG dehydration units for field gas gathering units, gas processing plants, and off-shore production units. Alco can provide a custom designed unit or for a quick delivery we have a stock program for the more common 16 (406 mm) to 36 (914 mm) glycol contactor sizes.

QBJ glycol dehydration units GUARANTEE outlet gas dewpoints and unit performance. Dehydration Package. When gas comes into contact with triethylene glycol, the water vapors entrained in the gas are absorbed in the TEG. Most product specifications require the maximum quantity of water in the gas to be 4 to 7 lbm/MMcf. The glycol-based gas dehydration system uses liquid desiccant technology to remove water from natural gas or carbon dioxide streams, thus preventing corrosion problems in downstream processes and equipment. The DEXPro team provides all necessary training for the operation and maintenance of the system. A dehydration unit is used to remove water vapor from natural gas streams to meet an outlet pipeline specification, which is normally 7lb/MMSCF or less.
