Natural Gas Dehydration
Natural gas dehydration involves removing water from the gas stream to meet pipeline specifications. Besides separating oil and some condensate from the wet gas stream, removing most of the associated water is essential. Oil and gas separators, located at or near the wellhead, collect much of the free water associated with extracted natural gas.
However, to further reduce water vapor and meet pipeline standards, a dehydration unit is often necessary. In fact, pipeline specifications typically require water content below 7 lbs./MMSCF.
Water vapor poses several issues, including hydrate formation, oversaturation of natural gas, and equipment corrosion. Hydrates are solid, ice-like crystallized compounds formed from hydrocarbons and water.
Hydrate formation occurs in high-pressure well streams at low temperatures. Interestingly, hydrates may even form at temperatures above freezing when high pressure increases saturation and produces more water vapor.
Hydrates can freeze and block pipelines, valves, and other equipment, halting production. Furthermore, water in natural gas also causes equipment corrosion.
Why Choose HAWK ENERGY for Gas Dehydration?
HAWK ENERGY provides integrated gas dehydration units using either absorption (TEG units) or adsorption (Molecular Sieve).
Glycol dehydration systems offer an economical, liquid desiccant method to remove water from natural gas and natural gas liquids (NGL). Glycols commonly used in the industry include triethylene glycol (TEG), diethylene glycol (DEG), ethylene glycol (MEG), and tetraethylene glycol (TREG).
Among these, TEG is the most widely used due to its efficiency. Additionally, TEG units can remove benzene, toluene, and other volatile organic compounds (VOCs).
Key Advantages of our TEG Unit:
Design can be sized for any flow or inlet process conditions.
Modular, Robust and Scalable Solutions.
Complete integration of the system on single skid
Low operating costs
Mol sieve dehydration units effectively eliminate water vapor from a natural gas stream. The mol sieve design incorporates a silicate compound with very small, precisely uniform pores. These silicate molecules trap water vapor as it flows through.
The basic design consists of two or more identical mol sieve units. In a typical two-unit design, one unit operates in dehydration mode while the other undergoes regeneration. Automatic switching valves alternate between modes, so when the dehydrating unit becomes saturated with water vapor, it switches to regeneration mode while the other unit takes over dehydration. HAWK ENERGY’s mol sieve dehydration units are skid-mounted for straightforward installation and mobility.
