Case Study 8 - Chemical Plant

Waste Heat Recovery from hot gases exhausted by Exothermic Chemical Process

System Description

Initial Situation

• Heat liberated in exothermic process of sulfonation is dissipated with the help of radiators
• The hot air from radiators is exhausted to the atmosphere through stack

Challenges

• The system must be integrated with the process plant
• Reutilize the waste heat to fulfill heat energy requirements of the plant

Solution Provided

• Waste Heat Recovery Boiler on process exhaust gases
• Once through finned tube cross flow type boiler
• Generation of steam for process use
• Reduces overall fuel consumption
