  • 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 Fouling of the active carbon is based on absorption so the only way to detect the carbon is no longer active is to check that the glycol is still clear.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 which might collect in the regeneration system. To increase operational uptime glycol filters might be redundant. The differential pressure between the inlet and outlet is monitored to indicated fouling of the filter element.

  • Gas Filteration & 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.

  • 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.

  • Lean Glycol Cooler

    After being cooled down in the glycol heat exchanger the lean glycol needs to be cooled down to approximately the feed gas temperature before entering the absorber. Depending on the application and client wishes the cooler can use several coolants like e.g. air, water or the gas leaving the contactor. However air coolers are most commonly used.

  • Knock-out

    For large quantities of contaminants a Knock-out drum can be installed upstream of the filter separator. This drum removes the majority of debris and liquids to prevent premature filter saturation and damage to the filters in case of liquid slugging by slowing down the gas velocity and allowing gravity to pull the contaminants down.

  • Analyzing

    The analyzer section can report the composition of gas components and calculate or measure the heat value, dew point and other values. These values can all be needed for custody transfer payments of gas turbine burner control. The sample probe guides a small stream of reduced -pressure gas to the analyzer, which cracks the gas into multiple components and vents waste gas to a safe location.

  • 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.

  • Fuel Oil Conditioning

    Fuel Oil Treatment systems prepare and condition the fuel oil to meet the exact fuel specifications required prior to combustion. Fuel oils are commonly used as a back-up fuel for gas fired power plants or as the main fuel for engine power plants. Our fuel oil treatment systems will be custom engineered for your project and can meet even the most stringent fuel specifications required for gas turbines.

  • Glycol Dehydration & Regeneration

    Natural gas streams produced by the wells or extracted from storage resevoirs often contain large amounts of water (vapour). Removal of this water from the gas stream is necessary to protect equipment further downstream from damage and prevent hydrate formations that may cause complete line blockage and corrosion. Glycol dehydration is the preferred liquid desiccant system that is optimized for the removal of large quantities of water from natural gas and natural gas liquids (NGL). Glycol Dehydration systems are the most common and economical means of water removal from these streams. In practice the glycols: Mono Ethylene Glycol (MEG), Diethylene Glycol (DEG), Triethylene Glycol (TEG), Tetraethylene Glycol (TREG) and Propylene Glycol are commonly used absorbents. TEG is the most frequently used because it offers an attractive balance in initial costs and solvent losses. Water is separated from the gas when the glycol is brought into contact with the gas in the absorber column at an elevated pressure, absorbing the water. The water rich glycol is reconcentrated in the regeneration package by heating the glycol at approximately atmospheric pressure to a temperature high enough to drive off virtually all water and other contaminants. The purified/ lean glycol is then cooled down and recirculated to the Absorber. Saturated/rich glycol is then pumped to the glycol regeneration package. This package strips the absorbed water, salts, and contaminants from the Rich Glycol. The purified/lean Glycol is then ready for reuse in the dehydration process. This combination of a Glycol based Dehydration system with a Glycol Regeneration package creates a closed loop system, minimalizing glycol losses and optimizing efficiency.

  • Buffering

    The buffer consists of a compressor, a buffer volume and an outlet system (usually a heater and pressure reducing system). The goal is to store enough gas to keep the gas turbine running if the gas supply is interrupted. The buffer must provide gas for long enough to allow the turbine control system to perform actions like switching over to backup fuel (usually diesel), start pumps and adjust burner settings. Buffer volume is customized to each project, since each combination of gas pressure, consumption and composition requires a different volume.

  • Pressure Reducing

    This section reduces the gas pressure to a stable level suitable for gas turbines, with the actual pressure being determined by self acting regulator valves. Remote set-point adjustment can fine tune the output pressure for each individual run, or force run switching for even wear on parts. Pressure reducing components vary depending on pressure levels, pressure differences, and allowable pressure drop across the system for low inlet pressures.

  • Heating

    The gas temperature drops significantly when pressure is reduced for gas turbine consumption. This Joule-Thomson-effect is countered by heating up the gas prior to pressure let-down, and prevents liquid dropout from the gas if one of the components passes below its dew point. strategically located sensors and switches monitor the design temperature, water level and pressure, safeguarding the entire system. Any additional results of a risk assessment/hazard and operability study (Hazop) can be implemented in the control philosophy for each project section.

  • Pressure Boosting

    Where needed due to low inlet pressures from the gas supplier, pressure boosting compressors increase the pressure to gas turbine levels and can be installed in parallel with the heating and pressure-reduction sections. The pressure booster is integrated in our control narratives in close cooperation with well-known compressor suppliers and uses proven technology.

  • Gas Metering

    Flow meters let you keep a close eye on the precise amount of gas being consumed. Volumetric or mass-flow meters monitor gas volumes for custody transfer (Sm3/Nm3, energy value in megajoules), gas turbine efficiency monitoring and/or quality control. We can measure flows of 1 million Nm3/h and above with accuracies to within 0.1%. Automatic (hourly, daily, weekly) reporting can include pressure, temperature, and energy value per standard cubic meter for billing.

  • Biogas Conditioning

    Biogas conditioning is a critical process for biogas management. Biogas primarily consists of methane and carbon dioxide, but may contain contaminants such as sulfur, silicon and moisture. Some of these elements can damage downstream equipment and can be dangerous to human health. Biogas Conditioning Systems remove the siloxanes, moisture and other contaminants from the sewage, digester and landfill gas to make it suitable for use.
