摘要： A process for the purification of the low-boiling constituents of a compresed gas mixture, such as a mixture comprising a carbonaceous gas, by cooling to low temperatures in cyclical alternated regenerators to condense high-boiling constituents of the gas mixture comprising (1) passing the gas mixture through a first regenerator from the warm end to the cold end of the same to cool the gas mixture and to condense the high-boiling constituents of the mixture thereby producing a purified gas stream; (2) passing a scavenging gas which is at a lower pressure than said gas mixture in the first regenerator through a second regenerator from the cold end to the warm end of the same to clean this second regenerator and to re-evaporate the high-boiling constituents, (3) passing at least part of the purified gas stream through a third regenerator from the cold end to the warm end of the same to re-cool this third regenerator, preferably to the temperature of the first regenerator, and (4) compressing and recycling at least part of the scavenging gas which has passed through the second regenerator through the first regenerator from the warm end to the cold end and repeating the process as defined above.

摘要： An apparatus is disclosed for cleaning the movable parts of a displacement-type liquid level sensor while the sensor is maintained in continuous service. Alternatively, the sensor may be isolated from the process and cleaned without disassembly. In either use a cleaning fluid is introduced to the housing of the sensor containing the movable parts. The flow of the fluid flushes solid particles off of and away from the movable parts of sensor, thus providing reliable operation for measuring the level of chemical liquids such as Phosam solution (diammonium phosphate), that are likely to form solid materials during processing or storage.
