H2S REMOVAL - SULFATREAT

ENERGY

Flargent offers fuel gas treatment solutions for electric power generation with engine generators or gas turbines. Fuel gas streams require this specific treatment to protect the facilities and maximize machine performance.

The conditioning heavy hydrocarbon content present in a fuel gas stream must be carried out in accordance with the specifications of the engine manufacturer. The methane number (MN) is the most commonly established parameter.

GAS CONDITIONING UNITS

For instances where certain components of natural gas need to be removed, Flargent manufactures gas conditioning modules, which may include hydrocarbon dew point adjustment or other conditioning. If natural gas is conditioned at its dew point, it has a higher detonation point and can be used as an efficient fuel in engines, turbines, furnaces and boilers. Once treated, the gas meets the required specifications, and potentially valuable condensed liquids are obtained.

BASED ON MECHANICAL REFRIGERATION

Flargent manufactures mechanical refrigeration gas conditioning modules to adjust the dew point of a fluid, from which its heaviest components are removed by cooling, depending on certain specifications. The gas to be conditioned enters the unit at high pressure through a separator vessel where entrained liquids are separated by gravity. Conditioning is performed by cooling the flow, which takes place in a closed propane refrigeration circuit.

BASED ON THE JOULE-THOMSON EFFECT

Flargent manufactures Joule-Thomson effect gas conditioning modules to adjust the dew point of a fluid, from which its heaviest components are removed by depressurization. The gas to be conditioned enters the unit at high pressure through a separator vessel where the liquids entrained by the gas are separated by gravity. The gas then flows through a heat exchanger where it is cooled by a flow of cold gas from the discharge. The gas is then throttled through a depressurizing valve which cools it even further. Thus, the heavier hydrocarbons are liquefied, and are sent to another separator using high efficiency internals. Finally, the gas flows through a gas-gas heat exchanger, cooling the inlet gas.

FUEL GAS CONDITIONING

Flargent supplies a variety of treatments for the conditioning of fuel gas streams to be used in motor generators, turbines, and other generation systems.

The solutions are customizable and include the adjustment of the methane number (MN), pressure regulation, and removal of contaminants.

ANTI-ICING UNITS

To inhibit the formation of ice in turbines in low-temperature environments, Flargent supplies anti-icing units that heat intake air indirectly. These fully packaged, modular units include a direct heater that heats a mixture of glycol and water that is circulated through a coil at the inlet of gas turbines used to generate electrical power.

This equipment, essential to protect turbines in winter, has moving parts that rotate at high speeds and includes a pumping system, an expansion tank, as well as a safety and control system and a motor control center (MCC).
