The electrostatic coalescence separation process comprises two principles: dehydration and desalting. In the Technomak technology, the high efficiency inlet distributor injects crude just below or between the electrical grids depending on inlet BS&W.

Between the grids the water droplets will attract each other and as a result, they coalesce, grow in size, and then fall out of the upward flowing crude. The treated crude is collected at the top of the vessel while the effluent water is collected at the bottom.

Technomak offers several coalescence technologies, including the following:

• AC technology
• AC/DC technology
• Multiphase volt technology

The applications include:

• Crude oil dehydration and desalting in production facilities
• Refinery inlet desalters
• Condensate / MEG separations

Heater Treater direct or indirect utilises heat and mechanical separation internals such as plate packs, baffles and electrostatic grids to break the crude oil emulsion and achieve up to 0.1 BS&W.

Indirect/direct fired heaters include the following:

• Insulated Heater Shell containing the heat transfer bath
• Heating Coil, immersed in the hot bath, which transfers heat to the process stream
• Firetube Assemblies (single or twin)
• Burner and BMS (Pilot burner, flame arrestor, pressure regulator, pressure gauge, control valves, thermostats etc.) designed to heat the fluid bath
• Flue/Exhaust Stack

The applications include the following:

• Conventional oil
• Heavy oil

Gas dehydration is the process of removing water from the gas stream in order to meet pipeline specifications. In addition to separating oil and condensate from the wet gas stream, it is also necessary to remove most of the associated water.

Most of the liquid, free water associated with extracted natural gas, is collected by oil and gas separators. However, additional water vapour removal is often needed with a dehydration unit using solvents like TEG or molecular sieve.

TEG is used to remove water from gas for corrosion or in order to meet sales gas specification.

Technomak provides customised design for the following:

• High acid gas concentration
• Associated gas
• Retro-condensation
• High BTX content

There is an Environmental Conscience to reduce Environmental emissions by flare gas. Technomak bring vast experience in gas treatment technologies to this segment as well, where the flare gas is recovered with suitable technologies and benefits End User on emission control and energy recovery.

Technomak can evaluate and offer below technologies as standalone or in combination for flare gas recovery;

• Suitable compressor technology to compress and treat the Flare gas for burner application.
• Gas Ejectors can also be utilized when there is small stream of high pressure gas or liquid available to compress the low pressure flare gas and prepare it for further treatment.
• Gas Membrane system to recover valuable hydrocarbon and increase the heating value of Flare gas for further application for burner or mixed with main gas train.
• Refrigeration packages to sub-cool the flare gas and separate the valuable NGL/LPG and treated gas for export.

• Technomak offers a complete range of fuel gas conditioning packages.
• They are designed to deliver clean, treated gas that is necessary for gas-driven equipment such as turbines and generators.

Technomak provides degasser for gas/liquid separation with removal of free and dispersed oil droplets and solid particles from produced water.

It’s often used as the first stage in produced water treatment scheme when there are different source of PW coming from high pressure separators.

• Reliable and robust de-gassing/Flashing of Produced Water
• Primarily designed for degassing, with option to add oil skimming capability for any accumulated oil.
• Based on inlet solid loading, suitable solid flushing arrangement can be added.
• Vertical configuration is also possible for reduced footprint.

Technomak designs and fabricates CPI units that can be quite effective as the primary oil/solids removal device in produced water treatment.

CPI units are designed for either degassed or live process fluids and this affects the mechanical design basis significantly. If CPI units are designed to contain live process liquids, it requires the use of pressure vessels to avoid uncontrolled emissions of hydrocarbon gases or liquids.

CPI units utilise Plate Packs as the primary method of allowing the settling of oil & solids within controlled parameters. The use of Plate Packs is integral to the separation process as they rely on Stokes’ law of settling oil and solids.

Technomak pro­­­­vides deoiling hydrocyclones where the internal geometry of each liner is designed to provide high separation efficiency.

• Multiple liner and vessel arrangement options allow for high flow rate and turndown.
• Robust and resilient to fouling and erosion.
• Compact arrangements available to optimise use of space.

The application includes downstream of a production separator/CPI/degasser /produced water collection vessel.

Technomak provides hydraulically-operated Induced Gas Flotation Units to remove dispersed oil droplets from produced water streams.

HIGF Units separate and recover oil and fine solid particles from water through the creation of fine gas bubbles (typically < 50 microns in diameter), that are dispersed through the incoming produced water.

• Cost-efficient and reliable design
• Capable of reducing dispersed OiW to 10ppmv

The applications include Secondary treatment to remove dispersed oil droplets from produced water and waste water streams and Fine suspended solids from produced and waste water streams.

Technomak provides nutshell filter (NSF) to produced water polishing.

• Pressure vessel with Deep Bed Filters for Oil and Solids removal from produced water
• Capable of reducing dispersed OiW and TSS below 5 ppmv or mg/l
• High efficiency Internal to ensure minimal nutshell damage during backwash

Technomak provides three types of NSF depending on process fluids:

A. Nutshell Filter with Scrubber Pump Design

After filtration cycle, the media is cleaned by re-circulating it through the scrubber pump and internal tubular screen. The pump is a proprietary equipment and specifically designed to handle the nut shell media without attrition of media.

Advantage

Robust design for challenging service - like high viscous oil and high inlet OiW and TSS loading.

B. Nutshell Filter with Internal Agitator

After filtration cycle, the media is cleaned by internal mechanical mixer with impeller. Thus the media is not taken outside the vessel.

The Internal mechanical mixer is specifically designed for nut shell media cleaning service without high attrition of media.

Advantage

The advantage is that they consume less power than Scrubber Pump design.

C. Nutshell Filter with Gas Scouring

After filtration cycle, the media is cleaned by scouring with fuel gas or nitrogen.

Advantage

• No rotating part
• No electrical load or power consumption
• Less media attrition/loss

Technomak Desanding Hydrocyclone (Desander) is a fit-for-purpose solid-liquid cyclone designed to remove sand from produced water streams. This technology is most commonly installed on the outlet of a three-phase or FWKO separator.

Designed primarily for water flow streams, the Desander removes sand to protect downstream oil-water separation equipment (deoiling hydrocyclones, CPIs, flotation cells, or media filters) or prevent solids transport to reinjection wells.

• Compact solids removal and washing technology
• Compact technology suitable for both onshore and offshore
• No rotating parts, no maintenance

The applications include:

• Wellhead desanders
• Removal of fine solids from produced water
