The invention is a heat integrated distillation column with a new method to control and cooling the distillation process. Also included is a method to optimize distillation columns, which are 'state of the art'.
The heat integrated column can be coupled with a solar thermal power plant, to build for example, an autonomous seawater desalination plant. Description including main features/advantages The distillation process is cooled internally in counter current, to win the process energy back. The energy content of the cooling medium is increased by the heat integration to a utilizable size. For the purpose of treatment of water are two stages as a middle size plant ( 500 m³/d ) suitable. Innovative aspects The inventions can reduce the energy consumption from 30% till 95 %. For this a Patent Cooperation Treaty (PCT)-application ( WO 2009/010250 A2 ) is filed. Current and potential industrial users/domains of application Chemical industry, seawater desalination, cleaning waste water, energy supply companies Current state of development Two technologies are tested in the production ( Fatty alcohol distillation plants ), but the heat integrated distillation column must be developed.
