Abstract:

The heat exchangers that assure the effluent reactor cooling from the installation Catalytic Reforming installation are built from carbon steel. After a relative short work time, about 2,5 years, it was necessary the beam cleaning and the stuffing of the pipes and after another 1,5 years it was replaced the tubular beam. To the external part of the pipes beam where the carbon steel is in contact with the effluent and to the internal part of the pipes in contact with the recycled water there are point - like deposits and also deposits having aspects of oxide, metal sulphide layers and fouling under which it appears local corrosion forms. In the paper there is studied the behavior of the carbon steel and brass to corrosion in the technological environments from the installation and it may be noticed that the brass presents advantages superior to the carbon steel for the construction of the tubular beam.
