Abstract— In this paper we present and explain innovative methods to solve problems cause of plugging a Brazed aluminium plate-fin heat exchanger as a part of the carbon monoxide processing cold box and focused to share the engineering techniques that were applied to figure out the problems and found solutions. Although the deplugging of the Brazed Aluminum Plate Heat Exchanger was not completely done, but with other solutions such as new methods of cleaning, designing and installation a new heat exchanger for pre-cooling Co-Recycle gas and try to modify some process Equipment, we succeeded to solve the problems and furthermore achieve to higher efficiency in Carbon Monoxide production. Conclusions of this paper contain experiences those are useful for Cryogenic industries with cold box problems.
Keywords: Cold box, Brazed Aluminum Plate-fin Heat Exchanger, Gas Dryer, Molecular Sieve, Plugging, Cartridge Filter.
