This article discusses redesign of major fluid catalytic cracking unit components to allow older units to process heavier feeds at high temperatures with less required maintenance and downtime. Although operating at higher temperatures can dramatically increase the chance of failures in the hardware components of the FCCU, there are negative affects. These are listed in the article and include: reduced load-carrying capability of steels; higher thermal expansion and thermal stresses; reduced abrasion resistance; and higher corrosion rates. The article provides an illustration of an example converter, revamped, to allow operation at temperatures to gain maximum benefit from today's catalyst properties.
