摘要： A flushing duct is installed on both sides of a table of the machine tool in a longitudinal direction of the table, a slope duct is inclinedly disposed below the flushing duct toward the coolant tank, each bottom surface of the flushing duct and the slope duct is formed with a V-shaped inclined surface and a streamlined bending portion to make flows of the coolant containing the microchips smooth, and a coolant supply valve is installed at a rear end of the flushing duct to facilitate flows of the coolant being discharged by supplying additional coolant. Further, a coolant tank is installed below the slope duct, a filter is installed in the coolant tank for filtering the microchips in the coolant. The coolant containing the microchips is transported through a return pump to a centrifugal separator device where the microchips contained in the coolant are centrifugally separated. A refined coolant through centrifugal separation is supplied to the machine tool, thereby preventing abnormal wear due to penetration of the microchips into rotating and sliding portions of the machine tool.

摘要： The present system is for simultaneous recovery of purified water and dissolved solids from impure high TDS water (1) which is achieved in a single step and eliminates the use of external thermal energy for making the system significantly efficient. It eliminates the use of boiler, cooling tower that reduces the overall capital cost and continuous requirement of external thermal energy for making system efficient. The simultaneous recovery of the purified water and solids from high TDS input effluent reduce the energy intensity of the system. Said system provides a vacuum system as heat pump which enables the system to be self-sufficient in thermal energy requirements for evaporation process and reduces GHG emissions significantly.

摘要： A sand separation system and method for operating a sand separation system, in which the method includes separating sand from a fluid using a separator. The method includes, signaling for a blowdown unit to blowdown the separator, opening one or more blowdown valves of the blowdown unit coupled to the separator in response to the signaling, so as to blowdown the separator, and receiving the sand from the separator into a sand disposal unit. The sand passes through the one or more blowdown valves that are opened. The method includes measuring a weight of at least some of the sand that was separated in the separator using a load cell of the separator, a load cell of the sand disposal unit, or both, and determining a blowdown interval for subsequent blowdown operations of the separator based in part on the weight of the sand.

摘要： Disclosed herein are systems and methods from processing flue gas desulfurization (FGD) gypsum feedstock and ash feedstocks, either separately or together. FGD gypsum conversion comprises reacting FGD gypsum (calcium sulfate) feedstock or phosphogypsum, in either batch or continuous mode, with ammonium carbonate reagent to produce commercial products comprising ammonium sulfate and calcium carbonate. A process to separate the impurities and convert the calcium carbonate to a pure precipitated calcium carbonate is disclosed. These impurities include a concentrate of valuable Rare Earth Elements, and radioactive thorium and uranium. A process to convert calcium sulfite to calcium sulfate using oxygen and a catalyst is also disclosed. Ash conversion comprises a leach process followed by a sequential precipitation process to selectively precipitate products at predetermined pHs resulting in metal hydroxides which may be converted to oxides or carbonates. The processes may be controlled by use of one or more processors.
