MRJ Engineering provides consulting, design and engineering services for mechanical equipment for Fluidized Catalytic Cracking Units.
Robert Junier holds 14 patents, demonstrating "MRJ Engineering" expertise and innovative design of the  main process control valves, such as slide valves and plug valves, for the FCC, orifice chambers for the FCC and the main control butterfly valves for the Power Recovery Train.
MRJ Engineering has developed novel ideas to improve catalyst withdrawal operations. Catalyst withdrawal operations will require more attention, now and in the future, since more frequent withdrawals will improve the efficiency of the cracking process, reduce the particle emissions and NOX emissions. More frequent withdrawal operations will also increase the wear on the withdrawal equipment, valves, piping and storage vessel. Consequently, more attention needs to be paid to the details of catalyst withdrawal operations. Valves will require automation and better erosion resistance, along with additional features to reduce the overall wear of the system. Storage vessel and piping needs to be evaluated, along with improving the valve operation. MRJ Engineering is ready to assist with your projects to improve catalyst withdrawal operations.
