Oil & gas separation 2/3 phases

2 & 3 phase separators remove liquids from natural gas. Vertical separators are ideal in case of space constraints at the well site or gathering station whereas horizontal separators are suitable for large quantities of liquids.Gas-liquid separation parameters vary from one well to another.

Praj has the right equipment to fit your diverse needs. We offer top quality 2 & 3 phase separators in horizontal and vertical designs that can be configured for both low and high-pressure applications.

Gas sweetening – H2S and CO2 removal

Praj offers amine plants for the removal of H2 Sand CO2 from a gas stream. The solvent amine is provided in different specifications depending on the type of contaminant to be removed. Equipment are delivered, packaged and modularized with a view to reduce costs of assembly and installation.

Dehydration – glycol/molecular sieves

Molecular sieve dehydration units provide an effective means to remove water from a natural gas stream.Praj offers monoethylene glycol (MEG) modules used by the gas

dew point adjustment

process to prevent formation of hydrates and clogging of the equipment. This procedure includes - regeneration module, degassing flash separator, filters for removal of hydrocarbons and solids particles, regeneration module and heat exchanger where the MEG transfer is cooled and serves to feed the pump suction. Thus, a water-poor high-pressure glycol stream is delivered to the skid edge, reinjected into the gas treatment plant closing the circuit.

Praj also offers triethylene glycol (TEG) modules for the removal of water in natural gas prior to being sent to a pipeline or entrance of a gas plant. This absorption process is preferably carried out at high pressure and is given inside a tower which allows the water vapor to be absorbed by the liquid TEG. It is then sent to a regeneration module.

Gas conditioning

Gas conditioning process has 2/3 stages

  • Particulate removal– dust, contaminants, rust and slug from pipelines is removed by mechanical separation and filtration
  • Removal of condensables- handling of water and other condensing constituents
  • Provision to superheat or dew point depression

The design approach is based on process simulation to determine the condensing temperature, hydrate formation temperature, water and constituent dew point before deciding the individual stages of cleaning and conditioning.

Dew point adjustment

Praj offers

dew point adjustment

plants for gas is conditioning so it meets the pipeline transportation specifications. This process increases removes the heaviest components, improving the quality and value. The conditioned gas at its dew point improves the detonation point and allows its use as fuel efficiently in engines, turbines, ovens and boilers. This adjustment can be achieved by the Joule-Thompson effect or by mechanical cooling.

Praj also offers and has commendable references in modularisation of chemical plants and industrial gas systems.
