What is a h2s scrubber?

What is a h2s scrubber?

hydrogen sulfide scrubber in the Oil and Gas Industry A hydrogen sulfide scrubber is a device for the chemical removal of hydrogen sulfide.

How does a vent gas scrubber work?

It operates on the gravity principle with the liquid directed to the bottom to run out a drain opening while the gas must make a 180 degree change of direction to exit through a top outlet. The unit is sized to allow low gas velocity so that gravity separation can be achieved.

What is a gas scrubber used for?

The Gas Scrubber removes traces of liquid droplets from gas streams to protect downstream equipment from damage and failure. It is typically used upstream of gas treating equipment that contains dry desiccants or mechanical equipment such as compressors.

What is a scrubber in a refinery?

Scrubbers are air pollution control devices that use liquid to remove particulate matter or gases from an industrial exhaust or flue gas stream. This atomized liquid (typically water) entrains particles and pollutant gases in order to effectively wash them out of the gas flow.

How does H2S scrubber work?

In the scrubbing process, sodium hydroxide reacts with H2S dissolved in aqueous solution to form sodium bisulfide (NaHS) and sodium sulfide (Na2S). The extent of reactions 1 and 2 are dependent upon the amount of NaOH that is available relative to the amount of H2S that is scrubbed into the solution.

Does water absorb H2S?

H2S and CO2, both of which are often referred to as “acid gases”, are only sparingly soluble in water at atmospheric pressure. Even at elevated pressure, the solubility of these gases in water is not very high; thus, it is uncommon to use water to absorb these gases in commercial-scale gas treating systems.

Are wet scrubbers expensive?

Scrubbers are commonly thought of as being too expensive. However, in fact, scrubbers themselves are very simple devices and are often the least expensive and most reliable device for removal of particulate from a gas stream.

What are the weaknesses in a using Wet Scrubber?

Some disadvantages of wet scrubbers include corrosion, the need for entrainment separation or mist removal to obtain high efficiencies and the need for treatment or reuse of spent liquid.

What is a H2S removal scrubber?

H2S REMOVAL This popular scrubber system is based on caustic (NaOH) treatment at low capital investment. The system, which initiates the scrubbing immediately, has an almost zero down-time. This quick operation extends its applications to systems where the gases are not available throughout the day allowing for easy on-off operation.

What is a packed tower scrubber and how does it work?

Monroe Environmental was called upon to supply a Packed Tower Scrubber designed to remove 98% of H 2 S fumes from various process operations from the plant’s wastewater treatment system. The system was rated for 30,000 ACFM. Installation was completed in 2016 and the unit passed all required EPA emissions tests.
