Electrostatic Desalter

With over a hundred operational installed units world-wide over the past 3 decades, Petro-Techna represents a premier, trusted and well-known brand in the oil desalting field. Our units operate in:

Upstream and Early Production Facilities

• Suited for high water cut (up to 20%) oils with focus on water removal to minimize corrosion issues during storage and transportation
• Ability to handle salt concentrations up to saturation limits (~360,000 ppm)
• Ability to piggyback with mechanical separators (where operations are close to vapor pressures) to ensure flooding

Downstream/Refining Applications

• Suited for precise salt removal in stabilized oils as a precursor to atmospheric distillation
• Salt removal efficiencies exceeding 95% for single stage and 99.5% for two stage units achievable
• Both AC and AC/DC grid systems utilizing three phase power supply with 100% standby spare availability

Separators

We specialize in design, fabrication, and customization for two and three-phase separators with proprietary internals for service in the upstream and early-production facilities.

Static Production Units

• Customized engineered designs for any throughput requirements
• Available options as skid-mounted modular solutions complete with auxiliaries
• Designed for severe services

Mobile Production Testing Units

• Fully mobile skid mounted design catered to local logistical constraints
• Efficient design for ease of transport, deployment, operation, and disassembly
• Weatherized for operations in rugged environments varying from harsh desert to extreme arctic type winter
• Available options to accessorize with supporting utilities including mobile flare stacks
• High accuracy measurements for well testing data
• Fully equipped for short term continuous operation in early-production facilities

Petro-Techna design provides superior performance through incorporation of our specialized vessel internals.

• Inlet Distributor, reduces the momentum of incoming fluid, and it prevents liquid break up and minimizes mist build-up
• Calming Baffle, standard perforated baffle minimizes turbulence inside the vessel. This allows efficient settling of water droplets in the aqueous phase and reduces undesired mixing
• Vane-type Mist Eliminator, efficiently removes mist and liquid droplets from gas stream
• Vortex Breaker, eliminates possible vortex on both Oil and Water outlet nozzles
• Mudwash/Sandjet System, jets water and creates turbulence to remove deposited soft sands/mud at the bottom of separator. It improves the performance of vessel while minimizes possibility of stable emulsions at the interface (due to solid accumulation)

We follow all applicable international design codes and standards including API, ASME and NACE.

Heater Treater

Petro-Techna offers upstream and Early Production Facility solutions for conditioning and stabilizing oil from reservoirs for storage and transport. This is achieved through piggybacking a combination of heating and mechanical separation (gravitational or electrostatically assisted) unit processes.

• Petro-Techna design has addressed the most common concerns associated with the operation of heater treaters. We have optimized our fire tube design to eliminate flame impingements and limit the heat flux which in turn reduces or eliminates local hotspots.
• Minimal footprint through piggybacking unit operations
• Reduced capital investment and higher ROIs for EPFs
• Ideal for lighter crudes and low salt heavy crudes

Direct Fired Heaters

• For a wide range of industrial applications including refinery unit charge heaters, distillation column reboilers, hot oil/glycol packages, regeneration heaters and waste heat trains
• Customized designs following API 560/530 with a range of salient features including rapid cycling abilities and specialized metallurgy
• Low emission high efficiency
• Engineering solutions can be provided for heating requirements of any scale

Indirect Fired Heater

• For applications requiring uniform and well distributed heating
• Ideal for processing fluids susceptible to thermal degrading with self-limiting film temperature
• Outlet temperature limitations based on heat transfer media utilized
• Design solutions for up to 25 MMBTU/hr capacity units

Convective (waste heat recovery type)

• For applications with limited heat flux and controlled film temperature
• Indirect heaters designed to rely solely on “Convective” heat transfer by eliminating radiative heat transfer
• In this design, a recycle stream is established to re-circulate cooler flue gas from the stack, to increase the volumetric flow and associated Nusselt Number which improves the efficiency of the convective heat transfer
• Lower flame and combustion effluent temperatures translate to enhanced heat recovery and potential reduction in emissions
• Increased safety inherently built in through separation of firing chamber from heating coils, which eliminates any hot spots
• Design solution ranging from 1 to 80 MMBTU/hr duty in capacity

We follow all applicable international design codes and standards including API, ASME, and NEFA. Other major international (Europe) and local design codes and standards can be catered to as required.
