| 20120097341 | EVAPORATION ASSEMBLY MODULE, ELEMENTS AND METHOD OF CONSTRUCTION THEREOF - A method of assembly of an evaporation assembly module. The evaporation assembly module comprises an evaporation element, a pipe having at least one fluid outlet and configured for wetting at least a portion of the evaporation element by passing fluid through the fluid outlet, and a support structure configured for holding the evaporation element in a suspended position. The method includes connecting the pipe to the evaporation element and subsequently suspending the pipe and the connected evaporation element to the support structure, in a suspended position | 04-26-2012 |
| 20140041811 | COMPACT WASTEWATER CONCENTRATOR USING WASTE HEAT - A compact and portable liquid concentrator includes a gas inlet, a gas exit and a flow corridor connecting the gas inlet and the gas exit, wherein the flow corridor includes a narrowed portion that accelerates the gas through the flow corridor. A liquid inlet injects liquid into the gas stream at a point prior to the narrowed portion so that the gas-liquid mixture is thoroughly mixed within the flow corridor, causing a portion of the liquid to be evaporated. A demister or fluid scrubber downstream of the narrowed portion removes entrained liquid droplets from the gas stream and re-circulates the removed liquid to the liquid inlet through a re-circulating circuit. Fresh liquid to be concentrated is also introduced into the re-circulating circuit at a rate sufficient to offset the amount of liquid evaporated in the flow corridor. | 02-13-2014 |
| 20150136333 | PROCESS AND PLANT FOR PRODUCING A SOLID PRODUCT - The present invention concerns a process for producing a solid product and a liquid product, comprising the steps of a. heating by direct steam injection a finely divided starting material, b. separating the heated starting material in the solid product and an aqueous liquid, c. heating and pressurizing the aqueous liquid, and d. reducing the pressure of the aqueous liquid thereby generating steam and the liquid product, wherein the steam generated in step d is returned to step a for injection into the finely divided starting material. The process suggests a solution for extracting the additional water appearing in the aqueous liquid due to condensed steam. | 05-21-2015 |

| 20150314214 | REVERSING MAPLE SYRUP EVAPORATOR - An apparatus for reversing flow of partially evaporated maple syrup in at least one evaporating pan includes a transfer line having an inlet for connected to a heating and pan for receiving partially evaporated maple syrup from the heating pan. A first sub-line extends from the transfer line and can connect to a first port of the evaporating pan(s). A second sub-line extends from the transfer line and can connected to a second port of the evaporating pan(s). A first outlet line extends from the transfer line or the first sub-line. A second outlet line extends from the transfer line or the second sub-line. When the first and second sub-lines are connected to the first and second ports respectively, the transfer line is positioned at a height no higher than the heights of the first and second ports. The first and second outlet lines are positioned at a height no higher than the transfer line. When fluid exits the evaporating pan(s) via the first or second ports, the fluid reaches the first or second outlet lines prior to reaching the transfer line. | 11-05-2015 |
| 20120247687 | Polymer Melt Distributor Header Design - A vessel header comprising a plurality of lateral flow tubes arranged in a parallel configuration and entering the vessel header through alternating header penetrations with a single header penetration per lateral flow tube. A method of increasing the throughput of a polymerization reaction comprising conducting the polymerization reaction in a reaction vessel comprising a plurality of lateral flow tubes arranged in a parallel configuration and entering the vessel header through alternating header penetrations with a single header penetration per lateral flow tube wherein the polymerization reaction displays an increase in throughput of 10% and a decrease in volatiles of from 5% to 10% when compared to a polymerization reaction carried out in a reaction vessel lacking a plurality of lateral flow tubes arranged in a parallel configuration and entering the vessel header through alternating header penetrations with a single header penetration per lateral flow tube. | 10-04-2012 |
| 20140041810 | SYSTEM FOR REMOVING HIGH PURITY SALT FROM A BRINE - A system for removing high purity salt from a brine. One system includes a first evaporator configured to receive a brine stream, to produce a first output comprising a sodium chloride slurry, and to produce a first intermediate output. The system also includes a second evaporator fluidly coupled to the first evaporator and configured to receive the first intermediate output, to produce a first recovery output, and to produce a second intermediate output. The system includes a third evaporator fluidly coupled to the second evaporator and configured to receive the second intermediate output and to produce a second recovery output. The first recovery output and the second recovery output are used to produce the brine stream received by the first evaporator. | 02-13-2014 |
| 20140069590 | METHOD AND SYSTEM FOR APPLICATION OF VACUUM EVAPORATION TO THE THICKENING AND DRYING OF TAILINGS IN OILSANDS AND MINERAL MINING OPERATIONS - A method and system for dewatering tailings from oilsands or other mining operations using vacuum evaporation. The method comprises i) providing one or more vacuum chambers and means for delivering the tailings to the one or more vacuum chambers; ii) delivering the tailings to one or more vacuum chambers in sufficient volume to partially fill the one or more vacuum chambers; iii) reducing the pressure in each of the one or more vacuum chambers; iii) applying heat to the tailings before, and/or after and/or during such pressure reduction to thereby dewater the tailings; iv) measuring the density or moisture content of the dewatered tailings and withdrawing the tailings from the one or more vacuum chambers when a predetermined density or moisture content of the tailings in that vacuum chamber has been reached. A number of vacuum chambers in series can be used. | 03-13-2014 |
