Steam jet thermocompressors or steam boosters are used to boost or raise the pressure of low pressure steam to a pressure intermediate bettveen this and the pressure of the motive high pressure steam. These are useful and economical when the steam balance allows the use of the necessary pressure levels. The reuse of exhaust steam from turbines is frequently encountered. The principle of operation is the same as for other ejectors. The position of the nozzle with respect to the diffuser is critical, and care must be used to properly posidon all gaskets, etc. The thermal efficiency is high as the only heat loss is due to radiation [5]. 

Many materials are suitable for refrigerant purposes, and each usually has some special characteristics that allow it to serve a particular application better than some of the others. Before selecting a refrigerant, it is important to evaluate its flammability and toxicity data, pressure-temperature-volume relationships, enthalpy, density, molecular weight, boiling and freezing points, and various effects on gaskets, metals, oils, etc. ... 

Each Nestpak module in the BiChlor electrolyser is sealed along its perimeter by a combination of a bolted flange and gaskets. This allows the sealing pressure to be controlled around all of the perimeter of each individual Nestpak. In a large-area bipolar filter-press electrolyser, sealing is only achieved with massive compression equipment and even then a variable sealing pressure is likely to exist around the module perimeter.
