Title: John H Blume: Innovator in Gas Treatment and Solvent Recovery
Introduction
John H Blume is a notable inventor based in Chester, NJ (US), recognized for his contributions to the fields of gas treatment and solvent recovery. With a total of 2 patents, Blume has developed innovative processes that enhance the efficiency of industrial operations.
Latest Patents
Blume's latest patents include a method for removing H₂S from gas using recycled NMP extraction solvent. This improved process involves passing hydrofiner tail gas into a scrubbing zone where it is contacted with liquid NMP to effectively remove H₂S. The resulting H₂S-rich NMP solution is then heated and passed into a stripping zone to recover a leaner NMP solution. This method is particularly beneficial for scrubbing H₂S from hydrofiner tail gas, making it suitable for use in lube oil extraction processes.
Another significant patent by Blume is a method of solvent recovery in autorefrigerant and ketone dewaxing processes. This process separates and recovers solvents from dewaxed oil and wax through high and low-pressure flashes followed by steam stripping. The use of a decanter and deketonizer prevents water buildup in the recovered solvent, thereby optimizing the recovery process.
