Biogas Dehumidification System | SKD
Skid-Mounted Packages for Biogas and Landfill Gas Cooling Applications
คำอธิบาย
Biogas, originating from biomass, sewage plants and landfill sites is gaining increasing worldwide importance as a recognised renewable energy source. Generally, biogas is saturated with water vapour and contains other impurities which, when used as fuel, must be removed to prevent corrosion and damage to equipment and systems and improve cogeneration unit efficiency.
Biogas is primarily composed of methane and carbon dioxide with smaller amounts of hydrogen sulphide and ammonia. Trace amounts of other gases like hydrogen, nitrogen or carbon monoxide are also present in the biogas. Usually the mixed gas is saturated with water vapour and may contain dirt particles.
The selection of effective biogas treatment equipment is therefore particularly important, both in optimising the cogeneration of electrical and thermal energy, making the most of the available renewable energy, and reducing energy consumption and operating costs to a minimum.
Parker’s solution is to dry the gas, firstly by cooling using a water-cooled heat exchanger working with an air-cooled water chiller and secondly, by removing the condensed water with a cyclonic water separator. The cooled gas can then be reheated to reduce the relative humidity and thus meet the technical demands of gas engines, turbines and other downstream equipment such as the Parker PpTek Siloxane Removal System and Biogas Upgrading System components
Features
- The Parker Biogas Dehumidification System is a compact, robust and easy to handle plug & play gas conditioning package ensuring significant cost savings in investment, management and operation
- Available in a wide range of sizes from 50 Nm3/h to 1500 Nm3/h, the Parker system has performances and flow rates aligned with typical biogas plant designs and CHP capacities
- All gas-side components are constructed from stainless steel (AISI304 or AISI316L) with additional pickling and passivation treatment in order to ensure highly reliable and continuous operation even in the harshest site conditions
- Designed using thermodynamic and fluid dynamic principles to ensure a high efficiency heat exchange and separation whilst maintaining low pressure drop
- Flexibility to use a wide range of cooler/ chiller combinations ensures the closest match to customer requirements thus delivering constant dewpoint performance regardless of fluctuations in operating conditions.
