    摘要: A power producing system includes a source of geothermally heated fluid having inorganic salts dissolved therein. The fluid is directed through a first direct contact heat exchanger in heat transfer relation with a working fluid of a type insoluble in a liquid including inorganic salts. The vaporous working fluid thus produced is expanded through a prime mover and then directed through a second direct contact heat exchanger. The vaporous fluid is condensed in said second direct contact heat exchanger by passing in heat transfer relation with a relatively cold heat exchange medium comprising a liquid brine solution. The condensed working fluid is thereafter returned to the first direct contact heat exchanger for repeated reuse in the cycle. Inorganic salts are mixed with either the geothermal heated fluid or the relatively cold heat exchange medium to maintain the percentage by weight of inorganic salt in each of the fluids above a predetermined value to prevent the working fluid from being absorbed therein.

    摘要: A modular water quality analysis system for steam electric power generating plants is disclosed which includes a novel single shell multicircuit heat exchanger having means to individually vary the rate of flow of cooling water through each of the multiple circuits therein so that the single heat exchanger can simultaneously cool a plurality of samples entering it at widely differing high inlet temperatures to the same lower range of outlet temperatures. The heat exchanger has a physical construction such that it can be mounted on top of the system rack which contains a plurality of modules of apparatus for accepting water or steam samples from various test points in the power generating system, reducing the pressure and temperature thereof, directing and metering the flow of samples, and performing analyses for such water characteristic as pH, specific or cation conductivity, dissolved oxygen, sodium content and the like. The fact that the single shell heat exchanger can be mounted on top of the system rack and thereby replace a plurality of individually manifolded and valved heat exchangers formerly mounted at the back of the rack makes possible a considerable saving in cost, space and weight, a greater flexibility in system layout design, together with greatly improved access to the system components for adjustment and maintenance purposes, and faster instrument response due to shorter sample tubing runs. This flexibility of design in the modular system also permits the same basic apparatus to be adapted to a large variety of different sizes and types of power generating plants having different analysis requirements thereby providing a custom installation for each plant which nonetheless retains all of the advantages of standardized design and equipment.

    摘要: A media-free filter device for a supercritical fluid process is disclosed. The media-free filter device includes a first pipe section connected in flow communication with a closed-loop system for a supercritical fluid. A y-pipe segment intersects the first pipe section at an intersection joint. The intersection joint intersects at a descending obtuse angle with respect to the first pipe section flow direction. The y-pipe segment is open at the intersection joint and closed opposite the intersection joint, in flow communication with the first pipe section. The y-pipe section induces an eddy current turbulence zone adjacent the intersection joint to remove substantially all contaminants suspended in the supercritical fluid; and the contaminants are deposited in the descending y-pipe segment. An SCO2 process incorporating the media-free filter device is also disclosed.

A fossil-fueled steam generator, steam turbine and condenser are connected to the water-steam circuit. In the cooling water circuit, a cooling tower and condenser are connected such that expanded steam is condensed by the exchange of heat with the cooling water circuit. The flue gas from the generator is cleaned in the flue gas cleaning system, and the cleaning system is supplied with process water. Process wastewater leaves the cleaning system. The cleaning system is connected to the cooling water circuit such that process water required for cleaning system is drawn from the cooling water circuit. To remove contaminated process wastewater, the cleaning system is connected to a wastewater treatment system having an evaporator, where system purified process wastewater is generated.
