Catalytic Cracking Unit Steam Generators And Waste Heat Boilers With Desulfurization & Denitrification System

Waste Heat Boiler (WHB) is a kind of boiler to produce hot water or steam by means of recovery of heat energy containing in the high temperature exhaust flue gas or liquid generated from the industrial process.

SMDERI has been engaged in research and development on waste heat boiler for catalytic cracking unit in oil refinery industries for more than 40 years and obtained numbers of patents. Based on his strong R&D ability and engineering experience, SMDERI provides design, fabrication, engineering, technical supervision and EPC contract service for the new-built project & upgrade reconstruction of various types of waste heat boilers.

Advantage: Produce superheated steam without fuel consumption, reduce emission of SOx, NOx and catalyst dust, so as to realize energy saving & clean emission.

Available Service: project design, equipment fabrication & installation, system testing & commissioning for new-built project / upgrade reconstruction of old boiler system.

Waste Heat Boiler for catalytic cracking unit with desulfurization & denitrification system
◇ This type of waste heat boiler is specially designed for the catalytic cracking unit with

desulfurization and denitrification device to match the requirement of latest

environmental protection regulation, which greatly reduces the emissions of NOx, SOx

and the catalyst dust.

◇ Various types of waste heat boiler are developed based on the research and study on

such key technologies and structures as positive pressure incineration of regenerated

flue gas containing CO, pressure sustained by the boiler body, arrangement of module

for ammonia spraying denitrification.

◇ The ANSYS software is applied to analysis the stress, calculate the strength and

deformation so as to design a proper seal structure and ensure the pressure at flue

gas side to be over 12Kpa and a long service life.
