Molecular Sieve Dehydration Unit
Molecular sieve dehydration by molecular sieve, silica gel and active alumina adsorbent for solid, removal from natural gas, synthetic natural gas or coal gas in the water (H2O), so as to achieve the purpose of purification of gases, reducing gas water dew point.
Application
Molecular sieve dehydration unit includes molecular sieve absorber, front-mounted coalescing filter, rear filter, gas heating furnace (or heat exchanger), gas air coolers, gas separator, gas water dew point Analyzer, automatic switch valve, computer automatic control system and other equipment and meets a filling quantity of molecular sieve selected.
In a typical surface processing train the sequence is: Wellhead → Separation → Treating → Metering → Pipeline.
Scope of supply
- 1, our company provides optimum design, equipment manufacture of prefabricated, valves, instrumentation and computer control system Assembly, software programming, on-site construction of production technical services, technical training, and a package solution, until the device calibration was successful.
- Is also responsible for the provision of long-term technical advisory services.
- 2, based on the underlying data and user requirements through optimized process solutions, provides heating such as step-down heating regeneration, regeneration, and blood pressure normal regeneration of three matching techniques.
- 3, our company provides unique regeneration technology and equipment, with regenerative gas does not need to be compressed, high rate of gas products, regeneration compared to absorption tower and its fatigue resistance strong, good safety performance, long service life, low investment, low energy consumption.
- 4, absorber operation of automatic monitoring and control system by computer according to the temperature curve required analog control, effective protection of the molecular sieve absorber and reduces volatility and avoid dust phenomena and improve life, and enhanced security.
Capacity, design conditions and scope of supply are confirmed per project.
