Where reliability is essential, Howden products can be trusted

The low vibration, low noise and compact design of Howden systems allow them to be integrated into a wide range of ancillary equipment ready for installation in remote and difficult locations. This makes them a uniquely efficient choice for process gas compression on offshore and FPSOs.  

 

Comprehensive, Customized Services

Oil and gas exploration and extraction often takes place in extreme climatic conditions, including hot, dry desert, sand and salty atmospheres. Our equipment supports operations in remote and hard to access locations.

Bespoke Packages

Howden offers a set of fluid handling technologies covering ventilation, compression and heat transfer. We provide solutions to many specific challenges met in oil extraction site and processes.

In-House Expertise

Howden engineering teams and field engineers have access to over 160 years of knowledge, meaning we can offer our expertise at every step of the process from product selection to ongoing support. Our worldwide organisation provides local responsive support to end users and customers.

Oil production map

  • Oil production/EOR Enhanced Oil Recovery

    Reinjection of gas (natural or CO2). Used within wellhead facilities to increase gas pressure for injection into the well. Howden has experience in Screw oil-injected solutions for Pre-Dehydration booster for the application.

    • Oil injected screw compressors, API618, Centrifugal compressor

  • Oil production/Sour gas injection

    Centrifugal compressors typically have dry gas seals to prevent the process gas from escaping. However, the seals leak small amounts of gas that in some cases must be contained.

    • API618, Diaphragm

  • Process cooling

    Site utilities/Cooling ACHE Air Cooled Heat Exchanger.

    • Cooling fans

  • Oil production/VRU, Vent gas compressor

    Crude oil is stored in pressurized tanks which causes evaporation to occur in the tank. The vapour is vented from the tank and can be recovered by compressing and processing for use in the fuel system or NGL recovery.

    • Oil injected screw compressors, Oil free screw compressors

  • Oil production/FPSO CO2 Gas drying for injection

    PSA mole sieve bed regeneration compressor. Regeneration compressors of gas drying units are integrated in FPSO ships. Periflow® Compressors ideally integrate gas drying units to regenerate molecular sieve beds (adsorption). Howden solutions are designed to handle various gas mixtures from different wells. Periflow® compressor solutions are compact, simple, versatile, and robust. Equipments can be started under process pressure and have very limited operations in its maintenance planning.

    • Peripheral

  • Oil treatment/GOSP Gas-Oil Separation Plant

    The separation of oil, condensate and gas is an initial stage of processing oil. The pressure of the gas flashed from the high pressure separator is likely to be sufficient for further processing, however gas flashed from lower pressure separators is likely to require compression to increase the pressure for recovery to other uses.

    • Oil injected screw compressors, Oil free screw compressors

  • Site utilities/Flare gas recovery

    Compression of corrosive gas. Recover off gas streams that are to be flared. A flare gas recovery unit (FGRU) may also be located at the GOSP to reduce flaring. Compression solutions are delivered with compatible materials and designed with protection level according area classification.

    • Screw compressors

  • Site utilities/Aeration and fumes extractions in offshore

    At emergency evacuation points, axial and centrifugal fans provide reliable ventilation in crisis situations. Living quarters overpressure to protect rooms and staircases from hazardous fumes.

    • Centrifugal fans, Axial fans

  • Site utilities/Electricity-Fuel gas

    Gas turbines used for power and compressor drivers can suffer from decreased power output as ambient temperatures increase.  A heat exchanger can be used to cool the inlet air down to the desired temperature via a mechanical refrigeration cycle.  The liquid refrigerant used is expanded at low pressure in an evaporator and the vapour is then compressed. Heat from the compressed refrigerant is then transferred through condensers back to the evaporator in a continuous cycle.

    • Oil injected screw compressors

  • Oil production/Injection CCS (CO2, and other gases)

    CO2 is used to ‘flood’ reservoirs by injection into the wellbore of existing and new wells. Screw compressor increase the pressure of CO2 prior to dehydration and injection. Howden has experience in oil-injected solutions for the application.
