ABSTRACT:
A heat exchanger for use in a sulphuric acid manufacturing plant to effect heat transfer between desired gas streams selected from air, sulphur dioxide and sulphur trioxide. The exchanger provides for hot or cold split flow gas streams through the exchanger shell with either mixing or splitting into two or more streams to provide for reduced condensible material condensation, corrosion, metal thermal differential stress and capital equipment cost. A preferred exchanger is used in combination with a sulphur burning furnace to provide an improved preheater.
