Wet eig shear reactor ,oil recovery from oily lakes

  1. 1. Shear Reactor + Ionizer for recovery of Turkmen Oil Lakes Process Summary: The system consists of a heated barge collector that pumps into a screening box to remove debris before being sheared with ionized water and a small quantity of proprietary reactant to crack and hydrate the sludge and thereby recover the crude oil. It is then clarified and filtered further as it passes through a weir system of conical vats, sand falling out the bottom while recovered crude and diluents flow out the top. Finally the liquids are spun through a series of cyclones to separate the crude oil from the diluents and to remove any last remaining sand. The diluents are recycled, the sand cleaned for disposal while the recovered crude oil exits to the end-product storage tanks. The system is rugged and easily scalable wherein all parts of the process have been used commercially to clean tank bottoms, sludge pits, drilling mud pits and fly ash ponds, etc. System Detail: Collection barge / heat-pad  Remote controlled, floating frame barge with heaters, fast flow pumps and insulated collection pipe to the shoreline processing facility  Heat supplied by 150kw generator powering a plasma arc to molten salt which circulates around the frame of the barge and around each of the pump inlets.  Ideal temperature ~140°F (60°C) to liquefy sludge while preventing volatiles from evaporating  Pump inlets have grate over them to keep out debris  If an object gets sucked against the grate, the operator will notice a decrease in flow, so reverses the pump to flush it out. (Each pump controlled separately)  Barge is modular with 4 pumps per section. Increasing capacity requires only snapping on a new section  While not at its limit, the longest distance already covered in the field by this system (pump + insulated pipeline) has been 900m. Screening Equipment  Grizzly Screen o Traps large & heavy objects, requires picking objects out by hand o Sits over the an insulated collection bin that is roughly the size of a railway box car  Note: Photo is not the actual screen, just representative of the equipment Page 1 of 4
  2. 2.  Shaker Tables inside insulated Collection Bin o The heated sludge drips through the Grizzly onto shaker tables o Solids bumped up the incline and over the back of the tables for removal from the sides while liquids flow to the center of the bin into the Hopper (described below) o Note: this system was developed and is already in use for removing drill-cuttings from drilling mud before recycling  This photo is just representative of the equipment Liquid Shear Reaction  A source of pressurized fluid (e.g., a firehose) is connected to a chamber which is open on one end, and leads to an exhaust hose on the other end. The pressurized fluid is forced through tapered nozzles (called eductor jets) mounted axially on the inside of the pump chamber, pointed in the direction of the exhaust hose. The passage of the pressurized fluid through the chamber and into the exhaust hose creates a suction on the open end of the chamber via the Venturi effect, such that any fluid open to the pump chamber will be drawn into the chamber and thence into the exhaust hose along with the fluid from the eductor jet nozzles.  As the fluid passes through a tapered jet, kinetic energy increases and pressure decreases drawing fluid from the suction into the flow stream. In this case the energy from the diluent (be it water, diesel or already lightened crude oil) is transferred to the sludge. Since the sludge is effectively ripped out of the eductor valve, it is sheared or cracked. Page 2 of 4
  3. 3. o The patented Turbo Shearing Eductors are purposed designed for this application where all wear surfaces exposed to high velocity flow is coated with DURALAN1.  Injecting a small amount (~1%) of a proprietary, non-toxic and biodegradable chemical – Synergen – to the diluent, enhances the cracking effect on the sludge.  Meanwhile, ionizing the diluent via the Ionizer frees hydrogen which then hydrates the cracked hydrocarbon molecules of the sludge which is thereby lightened.  Force is caused by a Fast Flow Pump o The Fast Flow pump has a unique double suction design that takes suction from both sides of the impeller eliminates thrust load problems associated with other centrifugal pumps. In fact the impeller has no contact with the housing. o It is reliable, because it has no wear plates, no mechanical seals, internal bearings, bushings, gears, or rubber impellers, i.e., none of the pump parts that create friction, wear, and pump failure. Shear, Weir and Turbo Separator After being screened by the Grizzly and passing over the shaker tables sludge is introduced into a hopper where the liquid level and chemistry is monitored and maintained. At the bottom of the hopper the sludge is sheared while being flushed with a dilute solution ionized water and Synergen. The feed rate into the 3 cell weir system is set to correspond to the capacity of flow through the process and the amount of sludge and liquid in all of the cells. 1 DURLAN products and coatings are specially formulated metallic alloyed hybrid polymers (MAHPs) that offer superior wear resistance, outstanding release characteristics, excellent tolerance for temperatures and chemical resistance. MAHPs were first developed as spray coatings. These coatings had properties similar to polyurethane but, unlike polyurethanes, could withstand temperatures up to 350°F and possessed significantly enhanced mechanical and chemical properties. MAHPs are based on a reaction of an amine polymer under specific catalyzed conditions that link particular metallic additives into the polymer chain. These components will react very rapidly (typically in less than 30 seconds) without the aid of an additional conventional catalyst. Page 3 of 4
  4. 4. Cell 1 Cell 2 Hopper Cell 3 Cells 4-6 The hopper is fitted with a patent-pending high shear eductor arranged below a proprietary rotary feeder. The speed of the feeder controls the feed rate into the next cell. The patented motive Fast Flow The pump operates at a rate of 660 gallons per minute taking a suction on cell three, pumping the liquid slurry mixture through the eductor and discharging the sand slurry to cell two. The sand is extracted from cell two and cell three as a clean, hydrocarbon-free material. Over flow from cell three into cell four is 98% oil. A variable speed pump is arranged on cell four that pumps at high velocity cyclone for a liquid/liquid separation in cell five. Here the hydrocarbon and any remaining liquid are separated into two flow streams while residual sand drops out. A pump in cell five uses a level control system to maintain a balanced return of the chemical and water, discharging into cell one and two assuring a zero-discharge of contaminants to the environment.
