We have a R1270 refrigeration cycle with Howden oil injected screw compressor and we decided to install a oil reclaimer heat exchanger to recover dissolve oil. On shell side cold liquid refrigerant with dissolved oil is placed and on the tube side hot R1270. The task was to increase the cold side temperature to reach its Dew point and separate oil from Refrigerant. But here comes the problem. Is there any alkylic bond made between oil and refrigerant? (HEX manufacturer claim)
Isn't it true that no bond should be made between compressor lubricant and medium of compressor?
Please advise.
