| A cooling circuit and an independent heat recovery circuit are associated with an internal combustion engine. A coolant is circulated a pump in a first and a second cooling sub-circuit. An increase in pressure in a work medium is achieved within the heat recovery circuit by a pump. This work medium is changed from liquid aggregate state to vaporous aggregate state and back to the liquid aggregate state in heat exchangers. This work medium is divided after the pump into two parallel partial flows and is changed into vaporous state in a first parallel branch in an EGR heat exchanger through which recycle exhaust gas flows and in a second parallel branch in an exhaust gas heat exchanger through flow exhaust gas downstream of the low-pressure turbine flows. This vaporous work medium is then fed to an expander and is then conducted through a cooled condenser and, liquefied again. | ||||||

| A process and apparatus for desalinating seawater or brine and purifying water which contains minerals, salts, and other dissolved solids while simultaneously generating power. The salinous water is heated in a boiler to form steam and a concentrated brine. The concentrated brine is removed from the boiler, the steam produced in the boiler is washed with fresh water to remove trace salts and inorganic materials, and water bearing trace salts and inorganic materials are returned to the boiler. The washed steam is expanded across a turbine to generate electrical or mechanical power which is utilized as a product. The steam exhausted from the turbine is collected and condensed, and one portion of the condensed water is utilized as a fresh water product and another portion of the condensed water is used as the wash water to wash the steam produced in the boiler. Energy efficiency is improved by heat exchanging the hot concentrated brine against the salinous feed water or by flashing the brine to produce steam. Boiler scaling and corrosion may be controlled by feed water pretreatment. By utilizing distillation combined with power generation, demand for fresh water and power can be satisfied simultaneously. Efficiency is further improved by utilizing a low pressure boiler at lower temperatures for desalination in conjunction with a high pressure boiler for producing power. | ||||||

| A method of and an installation for utilizing a thermal cycle by means of which a less volatile fluid can be compressed by the expansion of a more volatile fluid, is characterized in that, in the course of said cycle a less volatile fluid available in a fractionated separation zone working under a low pressure is put into liquid-vapour equilibrium in counter-flow in said separation zone at said low pressure, with one or more light fractions at most as volatile as said more volatile fluid, so as to obtain, under said low pressure, the more volatile fluid and one or more heavy fractions at least as volatile as said less volatile fluid, and in that, after compression of said heavy fraction from said low pressure to a high pressure, the more volatile fluid available in a fractionated mixture zone working under said high pressure is put into liquid-vapour equilibrium in counter-flow in said mixture zone under said high pressure with one or more heavy fractions so as to obtain said less volatile fluid at said high pressure. The invention is applicable to various technical fields including the distillation of mixtures of several constituents and provides a means of recovery in the form of mechanical energy, refrigeration and the like, of a substantial portion of the excess energy consumed in the primary process. | ||||||

| 217 | Method and means for generating electricity and vaporizing a liquid in a thermal power station | US3681920D | 1970-01-19 | US3681920A | 1972-08-08 | MARGEN PETER HEINRICH ERWIN |
| A thermal power plant operates with a varying production of electric power. Simultaneously, the heat generated in the plant is used for evaporating a liquid in a multi-stage vaporizing process. When the plant operates at low electric power the excess heat capacity of the plant is accumulated in a heat-accumulator. When the plant operates at high electric power, said accumulated heat is used for evaporating the liquid in the vaporizing process. In this way the vaporizing process can be operated continuously and steadily, independent of the variations in the production of electric power.

| 1,248,436. Steam turbine power plant. SALINE WATER CONVERSION CORP. Oct.23, 1968 [Oct.27, 1967], No. 50323/68. Heading F1Q. [Also in Division B1] Salt water, e.g. sea water, is pumped through line 42 and the tubes 46 of condenser 36 in which the steam exhaust from low-pressure turbine 12 is condensed; and the steam-condensate is pumped from line 38 through nozzles 68 into a multi-stage flash evaporator wherein it contacts and condenses the vapours evolved from heated salt water flowing through narrow downflow channels 62. Part of the fresh water withdrawn from the top condenser region 66a is passed through line 80, de-aerating tank 26 and heater 22 to the boiler 16 which supplies steam to high-pressure turbine 10. The remainder of the fresh water from condenser region 66a is withdrawn from the system as product. Before being introduced into the flash evaporator, the salt water from tubes 46 is further heated in heaters 48, 50, 52 by steam tapped from low-pressure turbine 12, and the heated water is passed through de-aerator 54 and then introduced into the top-most flash channels 62a. The condensate formed in heaters 48, 50, 52 is passed to condenser 36. Residual brine is discharged from the lower end of the multi-stage evaporator. The exhaust from the H.P. turbine 10 is passed through moisture separator 30 and re-heater 32, and is then introduced in L.P. turbine 12. Re-heater 32 is supplied with steam from boiler 16, and this steam then flows to heater 22 which is also heated by steam tapped from turbine 10. The steam from heater 22 and the moisture from separator 30 are passed into the de-aerating tank 26. | ||||||

Liquid, e.g. sea water, is evaporated in a series of stages 15 . . . 18, the first of which is heated by steam supplied by pipes 8, 9, 10 from a turbine system 1 . . . 4 generating electric energy, the vapour from stage 18 is expanded in turbine 20 and brings about the compression of vapour withdrawn from stage 17 into compressor 21, and some of the compressed vapour is used as heating-medium in stage 16. The remainder of the compressed vapour is condensed in heat-exchanger 26. Stages 16, 17 and 18 are operated in multipleeffect. Sea water is supplied to the system through pipe 7. The distillate, salt-free water, formed in the heating-elements of stages 16, 17, 18, and in heat-exchanger 26, is withdrawn from the system via heat-exchanger 24. Brine is withdrawn from stage 18 and heatexchanger 25. The sea water feed to stage 15 is preheated in heat-exchangers 24, 25, 26. Water withdrawn from the heating-element of stage 15 is returned by pipe 19 to the boiler for the steam-turbine. The shut-off devices in pipes 8, 9, 10 may be controlled by a device 14 sensitive to the output of distilled water. | ||||||
