Abstract

The present disclosure relates to a heat exchange arrangement comprising one or more shell and tube heat exchangers having a shell with an inner space, the heat exchanger having a tube-side inlet which enters a tube-side fluid to be heated or cooled in a front head located in between the tube-side inlet and a front tube sheet, from which the tube-side fluid then is distributed to a plurality of tubes which are held in place by tube sheets, and through which the tube-side fluid moves and during the movement is cooled or heated by a first shell-side heating or cooling fluid which moves through a first compartment with a first compartment inlet and a first compartment outlet, and by a second shell-side heating or cooling fluid which moves through a second compartment with a second compartment inlet and a second compartment outlet, whereafter the cooled or heated tube-side fluid is collected in a rear head located between a rear tube sheet and a tube-side outlet through which the cooled process gas leaves the heat exchanger, the tubes further being supported by a first and a second intermediate tube sheet placed between the front tube sheet and the rear tube sheet and between which a buffer compartment is formed with a buffer fluid with a buffer fluid temperature, the buffer fluid not chemically reacting producing insoluble compounds that precipitate as scale and not comprising compounds that chemically react with the shell resulting in corrosion at the buffer fluid temperature, and having a pressure which is higher than the higher one of the pressure of the first shell-side fluid in the first compartment and the second shell-side fluid in the second compartment.
