• Sulfur trioxide is mixed with water to produce sulfuric acid

• The process is highly exothermic and requires careful temperature control

• The final product is a highly corrosive and useful industrial chemical

Heat exchangers are devices used to transfer heat between two or more fluids.

• Shell and tube heat exchangers

• Plate heat exchangers

• Double pipe heat exchangers

• Spiral heat exchangers

• Air-cooled heat exchangers
