A system or a method adapted to perform purification of contaminated liquid (4), which system performs at least an evaporation process of the contaminated liquid (4), which evaporation is performed in an under-pressure (15). A mostly perfect purification of contaminated liquid (4) is achieved. A further object is to avoid the formation of foam in the evaporation process. The object can be fulfilled if the system comprises at least one common process enclosure (14, 101), which process enclosure (14, 101) comprises a plurality of technical functions, such as a heater (26), an evaporator (18) and a condenser (20, 105). Hereby a compact system can be achieved in which most of the technical features are placed in the same enclosure (14, 101). This enclosure (14, 101) can then be partly evacuated by a pump (38, 102) so that a common under-pressure (15) is achieved in the enclosure (14, 101). Hereby heater evaporator and condenser can operate at an under¬ pressure (15). |
