Method and apparatus for the reduction of scale, an alkaline in the distillation of water, 2002

摘要

The invention relates to a process and apparatus for reduce the scale in the installations seawater desalination. / p & & p & according to the present invention, use is made of a evaporator 10 comprising a side tube 14 and a dimension envelope, with a compressor of the steam associated 12. The water of the side tube is vaporised by exchange of heat with the steam from the condensation of dimension enveloppede the evaporator 10. The sea water passes through a aerator 42 and is introduced into the evaporator 10, whereas the carbon dioxide is also the evaporator by a device 60, 61, 62. A chemical additive is also contained in saline water for carrying out in combination with other means a prevention of the formation of scale. / p & & p & application to the technique of reduction or elimination of the scale formed on the pieces of equipment, in particular, 2002, seawater desalination.
