Abstract: A method is disclosed by which vapour is cleaned of gaseous impurities during evaporation of polluted liquids. Vapour is conducted via a boiler, a compressor to a heat exchanger (12) in which condensation takes place. In order to clean the vapour, a scrubber (14) is arranged between the boiler (3) and the heat exchanger (12), in which the vapour is scrubbed in several steps (17, 18) at different pH values. Thus, the step (17) is an acid step, whereas the step (18) is an alkaline step. In this manner, the vapour for condensation may be conducted into the heat exchanger and be condensed in order to remove a clean condensate without pollution of acid or alkaline substances.

Abstract: A method of separating water from an aqueous emulsion using a minimum of energy includes heating the aqueous emulsion in a sump, conveying concentrated emulsion from the sump to a heat exchanger so as to pass therethrough back to the sump, circulating water vapor and non-condensable gases from the sump through a compressor to raise its temperature and passing the heated water vapor and non-condensable gases through the heat exchanger to condense and heat the concentrated emulsion therein and evaporate water therefrom, a thermostat filled with water and water vapor, together with first and second pressure switches respectively communicating with the sump and the external atmosphere and the heat exchanger and the external atmosphere, maintaining a temperature differential between 0.5.degree. and 3.degree. C. between the aqueous emulsion in the sump and the temperature of the compressed water vapor and noncondensable gases.

Abstract: In systems or units for collecting volatile liquids, e.g. refrigerants from scrapped refrigeration systems, the liquid may be successively filled into a closed collector tank, inasfar as the vapor of the liquid as collected in the upper space of the tank will be condensed into the liquid as this rises in the tank. However, there will be separated also an amount of non-condensible gas, e.g. atmospheric air, that will cause a steadily increasing pressure in the tank, so that it is necessary to regularly effect a venting of the tank, that is a gas blow-off, by suitably controlling an upper blow-off valve on the tank.

Abstract: An apparatus for the registration of the humidity and acid content of a refrigerant or another non-polar liquid including a capacitive sensing element placed in the refrigerant or liquid and connected to an electrical evaluation circuit, the electrodes of the capacitive sensing element being formed of two different metals having different normal potentials, and the electrical circuit includes circuit elements for determining the resistive loss in the capacitive sensing element and circuit breakers for determining the current delivered by the sensing element.

Each of said containers (1,2) comprises two chambers (20,21);(30,31) for mutual heat exchange. Said discharge container (1) comprises a storage chamber (20) for liquid refrigerant and a suction chamber (21) positioned inside or outside the storage chamber. Said charging container (2) comprises a storage chamber (30) for clean liquid refrigerant and a metering chamber (31) for gaseous refrigerant to be charged to the refrigeration system (42). Said refrigeration system (42) is emptied by means of a compressor (3). Said recharging is effected by heating element (32) which evaporates the refrigerant introduced into the metering chamber (31) as a gaseous refrigerant until a predetermined pressure is established. The metering chamber (31) is recharged a predetermined number of times depending on the capacity of the refrigeration system (42) to be serviced.
