The Sandlogic DS1 is a 4 phase separator designed to reduce costs associated with the disposal of Frack Flow back during the drill out phase of the Well Completion of unconventional wells. The objective of the DS1 is to separate sand from the flow back propane, so no super sucker truck is required to clean out the tank at the end of the job saving the Operator both time and money. The DS1 also gives Operators the opportunity to flare or even tie into gas lines to ensure there is no methane vented into the atmosphere resulting in a far more environmentally friendly process
The DS1 tank consists of a V-bottom frack tank divided into 3 sections: The hopper section, the fines recovery section, and the working section. The hopper section consists of a hopper spec’d to receive a maximum of 1,000 gpm, and 73 cuft/hr of sand. The hopper will have an adjustable weir window to allow water to flow to the fines recovery section while the solids settle into the trough of the screw conveyor. The screw conveyor is designed to convey all the sand out of the tank rendering cheaper disposal costs for the Operator. Once water and fine sediment enter the fines recovery section, they are circulated via a centrifugal pump plumbed into a sump of the V.
The DS1 process begins by utilizing a proprietary 2 phase separator (called the Extractor) to de-gas the well back flow from the well, leaving liquids/solids to flow into the DS1 tank. The Extractor is vented to an approximately 8” flare line to a condensate knock out (scrubber), then to a flare stack OR in the future to a compressor to tie directly into the gathering system. The Extractor will have a P or S type trap at the bottom dump to maintain a hydrostatic level appropriate to keep a “gas lock” and not let entrained gas escape out of the bottom of the vessel. The vessel will be approximately 3’ diameter by approximately 10’ tall. It will be mounted on top of the DS1 tank and use hydraulic cylinders to lift the vessel into the vertical position for operation and horizontal position for transport. To avoid the Thompson Group patents the Inlet(s) will be in the TOP of the vessel not the side and the outlet will be out of the side not the top. There will be a 6” dump valve positioned towards the top of the vessel in the event the vessel became packed off at the bottom dump as a precautionary measure.The bottom portion of the vessel will have a port to receive circulated fine sediment and water from the“FRS”(fines recovery system)to prevent packing off. The bottom dump will go through the P or S trap prior to dumping to the hopper in the DS1 tank.The vessel will be able to handle 1,000 gpm max and 2MM CUFT/day of gas
