Abstract (en)

[origin: EP0917905A1] The apparatus to give a two-phase compression (10) to carry the energy of a number of fluids, where one is essentially liquid and the other is essentially a gas and at least one can be mixed with another, imparts a given energy value to each. The mixture from the compression stage (10) is in a liquid or essentially liquid form at a set pressure level. The entry and and/or outlet have hydraulic pump systems to move the liquid material. The apparatus has two sections, where the first gives a mixture at a pressure level and the second section converts the mixture into a second pressure level. The sections are sealed from each other such as by a labyrinth passage, and have links for the mixture to be transferred between them, with their hydraulic pump systems back-to-back to minimize the axial forces. A process and/or mixing stage is fed from the compression stage (10). The process/mixing stage has a refrigeration system, and a refrigeration circuit acts at least on part of the two-phase mixture and/or part of the mixture from the two-phase compression (10). A system registers the parameters of the liquid and/or the operation of the compressor, with a unit to calculate the necessary modification to the rotary speed of the two-phase compressor required for the process and/or the refrigeration action and/or the flow of the recirculating refrigeration fluid. A gas feed is between a pump stage and the two-phase compression, to introduce a gas into the pumped liquid, and a further feed passes gas into the mixture from the compressor.
