Natural gas dehydration device

Our dehydration devices can be divided into constant temperature dew point control systems, methanol and ethylene glycol regeneration devices, energy-saving molecular sieve dehydration devices, and triethylene glycol (TEG) dehydration devices according to different processes.

Technology introduction:

Constant temperature dew point control system

The method of using an external cold source reduces the water dew point of the gas to below -30 ℃, achieving dehydration effect while effectively controlling the hydrocarbon dew point. Suitable for use in complex components such as shale gas, sandstone gas, tight gas, and oilfield associated gas with high water content, mechanical oil, hydrocarbons, salt alkali, etc. Combined with our company's salt alkali separation device, the effect is better. 

Methanol and ethylene glycol regeneration equipment

Regenerate the ethylene glycol or methanol rich solution after absorbing moisture into a recyclable lean solution for recycling and treatment, meeting the standards for environmental protection and economic operation.

Energy saving molecular sieve dehydration device

Using molecular sieves to adsorb and remove saturated water from gas, reducing the water dew point to below -70 ℃. This method has simple operation, small footprint, and good dehydration depth, and is generally divided into two tower process, three tower or multi tower process. The disadvantage of conventional processes is that they consume a lot of energy and are not suitable for conventional high flow gas economy dehydration schemes, except for liquid chemical processes. 

TEG dehydration unit

Use triethylene glycol to absorb and remove saturated water from natural gas, reducing the water dew point to below -15 ℃. The TEG process belongs to the solvent absorption method, which uses ethylene glycol substances as absorbents to fully contact natural gas, allowing water to be transferred to the solvent and achieve dehydration. Glycol contains hydroxyl and ether bonds in its molecular structure, which can form hydrogen bonds with water. It has a strong affinity for water and has a high dehydration depth. Glycerols belong to the category of triglycerides, which are easier to regenerate and have a lean liquid mass fraction of up to 98%~99%. They have lower operating costs and are therefore widely used in large-scale dehydration. If applied to coalbed methane, due to its unique gas quality, the equipment structure and component selection need to be customized according to actual working conditions combined with usage experience.

Features and benefits of TEG solutions：

1. Features a unique exhaust gas treatment patent, widely used and meeting environmental protection requirements, it is more convenient to handle environmental protection procedures.

2. The absorption tower has a function of reducing the amount of ethylene glycol brought in, reducing the foaming or impurities caused by downstream gas, forming a "grinding wheel effect" that washes and thins the pipe wall, causing safety accidents such as explosions.

3. The waste glycerol solution generated during operation can be regenerated and reused using our company's proprietary technology - waste liquid on-site regeneration system, with a yield of 40-68%. 

Our advantages:

Dehydration devices can be categorized into various types based on different processes, mainly including constant temperature dew point control systems, methanol and ethylene glycol regeneration devices, energy-saving molecular sieve dehydration devices, and triethylene glycol (TEG) dehydration devices. The constant temperature dew point control system achieves dehydration by precisely controlling temperature; methanol and ethylene glycol regeneration devices utilize the regenerative cycle of chemical substances to achieve dehydration; the energy-saving molecular sieve dehydration device removes moisture through highly efficient adsorbent materials; while the triethylene glycol dehydration device is widely used in the field of natural gas dehydration, known for its high efficiency and stability. These devices each have their own advantages and are suitable for different industrial needs, effectively improving dehydration efficiency and reducing energy consumption.
