Activated Carbon Filter
Activated carbon filter The activated carbon absorbs troublesome organic impurities from the glycol to reduce foam formation. The activated carbon filter should be installed downstream the glycol filter to prevent collection of debris in the activated carbon filter. This can be well treating chemicals, compressor oils or BTEX components. Fouling of the active carbon is based on absorption so the only way to detect the carbon is no longer active is to check that the glycol is still clear.
Glycol filter The glycol filter removes solids from the glycol, that otherwise might collect in the regeneration system. To increase operational uptime glycol filters are generally made redundant. The differential pressure between the inlet and outlet is monitored to indicated saturation levels of the filter element.
Liquid Filtration & Separation
Liquid filtration & separation All contaminants are removed from the oil stream; basket strainers will remove the coarse debris, and coalescing filters will remove the fine solids & water. The strainers and filters can be installed in a 2×100% configuration, integrated switchover valves allow you to switch to the stand-by filter without interrupting the oil flow.
Knock-out vessel For large quantities of contaminants a Knock-out drum can be installed upstream of the filter separator. The knock-out drum removes the majority of debris and liquids from the gas stream. The volume of the knock-out vessel slows down the gas velocity, which allows gravity to pull the contaminants down. Removal of the majority of the contaminents prior to the filter separator helps to prevent premature filter cardridge saturation. Additionally, the knock-out drum removes large quantities of liquids which protects the downstream filter separating section from liquid slugging.
Particulate removal Particulate removal is essential to protecting sensitive equipment downstream. A mesh gas filter with a pore size of 3 to 6 microns disperses the gas stream, causing any fine particulates to drop out.
Final run The final run consists of a series of equipment that form the last line of defense to protect the Gas Turbine from foreign material. The final run section generally includes consumption flow metering, performance heating, filtering and a shutoff valve.
Condesate storage The condensate storage section holds drained material from the filter separator (and/or Knock-out drum) until it can be hauled from site. As elsewhere in our system, we use proven and reliable technology and can customize the design to your exact requirements. The vessel can have an unlimited range of volumes, depending on your specific needs. Options include single-wall tank or double wall for additional containment safety, a vacuum leak detector, condensate unloading pump, various level measurements, and a flame arrestor for maximum safety.
Gas Filtration & Separation
Gas filtration & separation The filter separator removes foreign materials like debris, dust and liquids to prevent them from damaging downstream systems. We monitor any rising differential pressure between inlet- and outlet of the vessel, which indicates that the filter elements should be replaced. We have worked with gas supplies having high acid and salt content, always conditioning the gas to give a clean dry stream to turbines for maximum up-time. Filters are automatically or manually drained, and there are various mounting orientations for easy operation.
Fuel Gas Conditioning
Fuel gas treatment systems must work safely and efficiently at all times. Fuel gas treatment is a critical step to reach optimal performance & efficiency in gas turbine power plants; where even the smallest deviation in power generation efficiency can have huge financial implications over time. Fuel gas conditioning systems, also known as fuel gas treatment systems, are designed to supply clean, treated natural gas according the exact fuel specification required to your gas-driven equipment. Meeting every client’s fuel gas specification consistently is what sets us appart from the competion. We do this by building quality and reliability into our skid-mounted fuel gas conditioning stations right from the start. The complete turnkey fuel gas conditioning system is factory-tested. We QC everything, from the actuators on the fuel gas inlet valves to the filter cartridges inside the final run filters. We ensure that our systems confirm to the highest quality standards and are designed and configured to consistently reach optimum performance on your site. That’s why many of the world’s leading Engineering, Procurement & Construction (EPC) contractors, OEM Turbine manufacturers and end-users turn to Petrogas, for peace of mind. We have successfully supplied gas conditioning systems to some of the world’s largest combined cycle power plants, natural gas distribution networks and gas processing plants. Our turn-key process solutions are tried, tested and proven in the field. Petrogas fuel gas treatment systems are designed and build to provide the fuel quality required to reach optimal performance and maximum lifetime on your gas-driven equipment.
