摘要： 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.

摘要： Dilute waste sulfuric acid is concentrated by heating it against product acid and then passing it through two contact zones separated by a collection zone. The dilute acid scrubs vapour produced in the collection zone and from a high temperature acid reboiler. In the collection zone acid is drawn off, heated, and recirculated to the collection zone where part of the liquid flashes to vapour. The main heat input is to the more dilute low temperature recirculating acid from the first contact zone rather than to the more concentrated high temperature acid in the reboiler. As a result, less sulfuric acid vapour is generated; the major portion of the heat can be fed to the process at low temperature; and only a single column is required, having a single cool clear water vapour exit stream to dispose of.
