TECHNOLOGIES

Patented Products

Vacuum Membrane Distillation

VMD in AQUA-SEP™

VMD systems utilize a membrane-based separation process for extracting low concentrations of volatile organic compounds (VOCs) from water by partial vaporization through a polymeric membrane. The membrane acts as a selective barrier between the feed in the liquid phase and the permeate in the vapor phase. The customized membrane allows only the selected desired component of the mixture to be transferred through it.

Image of water splashing

VOC-SEP™ (PERVAPORATION & VAPOUR PERMEATION) systems can be developed to utilize either vacuum membrane distillation technology or pervaporation.

Principle of Operation

VOC-SEP™ (PERVAPORATION & VAPOUR PERMEATION) systems utilize modules made from proprietary polymeric hollow fiber membranes. The hydrophobic (water repellent) nature of the membrane prevents the water from entering the pores of the membrane and allows only VOC's to pass through.

VOC-SEP™ (PERVAPORATION & VAPOUR PERMEATION)units can be designed for batch or continuous operation depending on the volume of the process stream to be treated. The degree of separation is controlled by the membrane and fluid proprieties.

In continuous processes, multiple modules in series may be required to achieve the desired degree of separations.

Petrochemicals & Water Filter

A vacuum pump is used to maintain a vacuum on the permeate side of the module. Permeate vapors from the vacuum pump discharge are condensed in a condenser.

Pervaporation or Vapor Permeation

AZEO-SEP™ & VOC-SEP™

AZEO-SEP™ (PERVAPORATION & VAPOUR PERMEATION)systems use pervaporation for separation or purification of various liquid mixtures by partial vaporization through a non-porous membrane.

Principle of Operation

The membrane acts as a selective barrier between the two phases; the liquid phase feed and the vapor phase permeate. It allows the desired component(s) of the liquid feed to transfer through it by vaporization. The separation process is mainly due to polarity difference and not on the volatility difference of the components in the feed.

Limitations of Conventional Distillation

Distillation is a conventional fluid mixture separation technology that can separate components with different volatilities and markedly different boiling points (i.e. Benzene/Toluene mixture).

Pervaporation or Vapor Permeation Graph

However, distillation is extremely complicated when the concentration of the separating components are similar in the liquid and vapor phase, called the azeotropic point (e.g. Ethanol/Water or IPA/Water mixtures).

Distillation alone cannot perform any further separation beyond the azeotropic point.

Commodity Filtration Systems

Microfiltration

Micro-filtration and ultra-filtration are pressure-dependent processes. They remove dissolved solids and other substances from water to a lesser extent than Reverse Osmosis, yet with a high level of purity.

The membranes used in Micro-filtration have with a pore size of 0.1 – 10 micrometers (µm). The membranes used in Ultra-filtration have smaller pores varying in size from 0.001 – 0.1 (µm). This makes Micro-filtration excellent for the pre-treatment of surface water, sea water, and biologically tested municipal effluent.

Examples include:

  • Cold sterilisation of beverages and pharmaceutical
  • Clearing of fruit juice, wines and beer
  • Separation of bacteria from water (biological waste treatment)
  • Effluent Treatment
  • Separation of oil/water emulsions
  • Pre-treatment of water for nano-filtration or Reverse Osmosis
  • Solid-liquid separation for pharmacies or food industries
Ultrafiltration

Ultrafiltration is a membrane process that is most commonly used to remove suspended or dissolved solids from a process liquid. The membranes are selected to remove impurities based on their molecular weight. Ultrafiltration uses hollow fibers of membrane material. The feed can flow either inside the shell, or in the lumen of the fibers.

For more information about ultrafiltration, please contact us at sales@petrosep.com.

Ultrafiltration Industrial Applications

Ultrafiltration is used in industry to separate suspended solids from solution. The particles that are removed vary in size, and their removal is a function of the pore size.

Ultrafiltration is used in:
  • Paint recovery in the automotive industry
  • Protein isolation
  • Removal of colloids
UF Industries

Ultrafiltration is used in many industrial applications, including the power, food, pharmaceutical, biotechnology and semiconductor industries.

Reverse Osmosis

Reverse osmosis is a membrane process used to remove dissolved solids from water. The process is suitable for a wide range of applications, including:

  • Fresh water purification for boiler feed
  • Brackish water desalination
  • Sea water desalination
  • Concentration of impurities

These systems can be supplied in any size, from several cubic meters per day to thousands of cubic meters per day.

Principle of operation

Reverse osmosis uses a high pressure feed to overcome the osmotic pressure of the system. It is this pressure that forces pure water through the membrane, leaving the undesirable impurities behind.

Plant Configuration

The optimum design for a reverse osmosis plant will depend on the application. To find out the best design for your application, we encourage you to: Contact us at sales@petrosep.com

Petro Sep has developed customized solutions for complex separation of fluids for a growing number of industries and applications, including the longstanding mature industries along with new emerging ones, such as municipal or industrial hazardous waste, mining, oil and gas, chemical solvents, water desalination, pharmaceutical industries.

Using its patented and proprietary products and processes, Petro Sep can create bench-scale research units, pilot or large-scale plants that are standalone, hybrid or integrated with existing industrial plants.

INDUSTRIES

Oil & Gas

Oil Shale and Tar Sands have destructive environmental impacts that are also water and energy intensive, such as the industry practice of fracking.

Image for water splashing

Petro Sep can treat the produced water (a result of Oil & Gas extractions) instead of disposing it as a waste, and it can also recycle the water back, eliminating the need for constant new supply of water.

Petro Sep can also develop custom solutions that cater to specific sites and address needs or meet specific targets set by the customers.

For example, produced water from an oil sand can be recycled and reused by Petro Sep and azeotropic mixtures may also be separated (e.g. ethanol/octane) in the process.

INDUSTRIES

Landfills & Municipal Waste

Municipal waste, solid or sewage, and leachate from landfills pose a growing challenge for the future of urbanization.

Landfills & Municipal Waste

Petro Sep systems can process municipal waste and turn it into a business opportunity. It can extract sugar, ethanol (biofuel) from the solid waste, and its technology may also be used to treat and recycle the sewage wastewater as well.

Using its patented and proprietary products and processes, Petro Sep can create bench-scale research units, pilot or large-scale plants that are standalone, hybrid or integrated with existing industrial plants.

INDUSTRIES

Industrial Waste & Solvent Recovery

Industrial plants consume solvents and produce wastewater that is usually discarded and disposed in environmentally disastrous manners.

Industrial Waste & Solvent Recovery image

Petro Sep can treat highly complex fluids and separate them into individual constituents with a possibility of a zero-liquid discharge at the end. This enables the recycling of the input solvents and substantially reduces the by-product waste and its treatment or disposal.

For example, with Petro Sep systems, high value solutes that remain in the waste stream by many industrial processes, such as L-Quebrachitol (rubber), paint (automotive), ink (print), toxic organic solvents (electronics & semiconductor)…etc., may be recovered with virgin-grade quality and ultrapure water (UPW) as a by-product.

INDUSTRIES

Mining

Mining and ore processing consume a substantial amount of water. Many mines also leave barren land behind and a list of short- and long-term environmental impacts that may not be remediable.

Mining industries

Petro Sep can develop custom plants that will be able to extract solutes and reduce the wastewater produced in the process, which also minimize fresh water supply requirements.

For example, lithium mines and ponds can be replaced with Petro Sep units that will eliminate the environmental damage to the land and, in fact, will be able to recover and extract lithium at a much quicker turnaround cycle.

INDUSTRIES
