    摘要: Oil reclamation for a flooded screw type compressor is improved by replacing the normal distillation still with a refrigerant vaporizer made from a small diameter pipe conduit and a low temperature heat source such as heat tracing. The system purifies lubricating oil of refrigerant by boiling small batches of collected lubricating oil from the bottom of the chiller. Using a small volume for vaporization of the refrigerant allows a low temperature heat source to effectively vaporize the refrigerant from the circulating lubricating oil without complicated systems for control or pumping. A particular form of the vaporizer is simply a small diameter pipe surrounded by heat tracing tape.

    摘要: The present invention is a process for controlling a sorption cooling or heating process which employs an adsorption zone in fluid communication with a refrigeration circuit to pass desorbed vapor upon heating to a condenser and to adsorb refrigerant vapor from an evaporator when cooled. The process is cyclic and comprises heating the adsorption zone during a desorption step and cooling the adsorption zone during an adsorption step. The heating and cooling of the adsorption zone wherein a heat exchange zone is in intimate indirect thermal contact with the adsorption zone is provided during a cyclic process by alternating the flow of a working fluid at a hot source temperature or a working fluid at a cold source temperature through the heat exchange zone to provide the heating and cooling. It was discovered that by conserving hot working fluid at or above a reference temperature in a hot working medium reservoir, fluctuations in the heating requirements at the hot source can be minimized and significant cost savings could be achieved. The present invention can provide significant benefits in the refining and petrochemical process industry where product streams from catalytic reactions at elevated temperatures must be cooled to ambient conditions for storage or transport.
