Oil Treatment

Oil process solutions you can depend on.

ProSep's onshore and offshore oil process solutions offer designs based on more than hsalf a century of oil treating project and operations experience. Whether you decide on individual treating units or fully integrated process trains, ProSep's experience ensures the solution will be right on. To meet your specific treating requirements, our seasoned know-how provides you with the best-fit technology and, as required, new concepts to customize established designs.


Typical Crude Oil Production Train

Note: The oil train shown in this diagram represents generally accepted equipment available to treat produced oil to product specifications. This does not mean that all of this equipment would be necessary for every application.

Modular Design

In order to provide the flexibility demanded by today's oil & gas industry, ProSep utilizes a modular design system to develop equipment that can accommodate multiple treating issues.

Horizontal Flow Regime

Our separation technology provides the distinct advantages of a horizontal flow regime, such as the ability to incorporate a vertical electrostatic grid system. As the oil phase progresses downstream through the vessel, the oil can be exposed to multiple stages of electrostatic fields of varying potentials. Built-in adjustability allows these fields to match the water content remaining in the oil phase, thus ensuring complete and efficient dehydration while optimally using energy.

Stemming from this is the facility to incorporate mechanical coalescers in combination with the electrostatic grids. These coalescers can be placed in the vessel's process stream to provide either bulk or polished coalescence.

Additional Design Advantages

In addition, ProSep's FWKO designs are based on empirical data developed over 30 years of practical experience, and our thermal treaters combine both heating and coalescing capabilities in one efficient process unit.

Applications

  • Process Liquid Stabilization (Degassing)
  • Bulk Free Water Removal
  • Pipeline Sales Oil Dehydration and Desalting
  • Optimized Energy Utilization (Preferential Crude Oil Heating, Not Bulk Fluid)
  • Optimized Fresh Dilution Water Utilization (Proprietary Mass Transfer Devices)

This just scratches the surface. Contact an office near you to explore the possibilities of partnering with us to address your oil processing needs.

Enhanced Desalting

Desalting is a crucial step for crude oil downstream refining processes since both the free water and emulsified water contain salt, which can cause corrosion, leading to failure of critical process equipment, i.e. hydrocracker.

ProSep's efficient injection and mixing technology holds the key to effective salt content removal, efficient utilization of wash water and chemicals, and improved crude-water separability. Besides increased treatment capacity, the technology allows reduced wash water requirements, reduction in oil in water content, and low installation costs and thus high returns on investment.

The injector mixer system generates a homogeneous phase flow over the pipe cross-section in combination with a pressure drop that is significantly lower than conventional mixing methods, while controlling shear forces. This achieves an improved oil-water separation, with less emulsion.

ProSep's Desalting System has demonstrated operational benefits for most crude oil wash water flow rated over a wide range of specified pressure drops.

Benefits

  • Reduced wash-water consumption
  • Reduced residence time in coalescer separator
  • Reduced pressure drop
  • Improved oil-water separation
  • High turn down
  • Easy process modification - low installation cost
  • Reduced chemical consumption
  • Robust flanged - unit - no operator involvement required
  • Maintenance free

C100 Injection Mixer

ProSep's patented C100 injection mixer is designed to achieve efficient mass transfer for both liquid-liquid and gas-liquid flows.

Technology

The mixer produces a homogeneous droplet distribution by secondary droplet break-up, maximizing the contact surface of the injected chemicals and the oil flow. The C100's design principle consists in establishing a high local dynamic pressure by accelerating the oil and transferring the high momentum to the liquid.

Features

ProSep's compact injection and mixing technology can easily be installed independently of pipeline orientation and has no upstream pipe requirement. TheC100 is supplied as spool pieces for installation between RF/RTJ flanges and has no moving parts. The large oil-liquid exposure area which is generated due to the secondary droplet break-up is another advantageous feature of the C100.

Benefits

  • High degree of mixing at a low pressure drop (around 0.2 bar (2.9 psi))
  • Reduced chemical consumption
  • Reduced environmental footprint
  • Efficient in high flow variation situations
