The hot blowdown water passes through a self-cleaning vertical heat exchanger coil. Fresh makeup water is the shell side counter flow cooling media. No flash steam is created in these simple heat exchangers. The Type HX is designed for blowdown flows up to 3,500 lbs. per hour from boilers up to 150 psi. ASME 150 psi shell construction.

Fluid catalytic cracking (FCC) is one of the most important conversion processes used in petroleum refineries.It is widely used to convert the high-boiling point, high-molecular weight hydrocarbon fractions of petroleum crude oils into more valuable gasoline, olefinic gases, and other products. Cracking of petroleum hydrocarbons was originally done by thermal cracking, which has been almost

through a pressure reduction orifice chamber, a steam generation system (heat recovery) and finally to an electrostatic precipitator. The precipitator removes any remaining catalyst fines. A power recovery turbo-expander is sometimes included while other locations include a CO Boiler to complete combustion from a partial-burn regenerator.

Depending upon the regeneration process two types of heat recovery (i.e. fired boiler and unfired waste heat boiler) are available: The first solution is common when carbon deposits on catalyst are removed with low excess air. The flue gases are rich in carbon monoxide to be converted to carbon dioxide before its discharge to atmosphere. CO boiler design must take into consideration the three reasons …
