<p>A gas mixture separation plant e.g. for separation of air by cryogenic distillation, comprises at least one compression unit (1), a purification unit (2) and a separation unit (3). At least one of the units is equipped with a cabin (A,B,C) containing a control and command system, and/or an analysis system and/or an electrical distribution system necessary for the functioning of the plant. The plant can preferably be arranged so that each of the units has its own control, analysis and distribution cabin, all the cabins can be connected to a central supervision room which receives information from all of them. Cabin A preferably contains low tension outputs for compressors, refrigeration water temperature analysers, and compressor sensors and actuators. Cabin B preferably contains control and analysis systems for the compressed air purifiers, and cabin C has similar equipment for the distillation unit.</p> |
