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. All according to the temperature such a blow-off, however, may be connected with a more or less pronounced and undesirable blow-off of the condensible gas, and the blow-off is minimized by a blow-off valve being controlled from a differential pressostat, which is influenced partly by the actual pressure in the collector tank and partly by the vapor pressure of from a confined volume of the liquid in its pure state. Thereby, the pressure contribution from the condensible gas in the tank, no matter the temperature, is compensated for, and thereby a more favorable controlling of the blow-off for minimizing the the undesired part of the blow-off product will be achieved.
