摘要

INVENTOR: ARTHUR C. HOMME, JR.INVENTION: IMPROVEMENT IN CONTACT SULFURIC ACID PROCESSEMPLOYING DOUBLE CONVERSION/DOUBLE ABSORPTIONABSTRACT OF THE DISCLOSUREImprovement in the contact sulfuric acid process employingdouble conversion, double absorption using a cold, sulfur dioxide-containing feed gas stream obtained from a wet gas purificationplant, which involves by-passing a portion of the cold feed gasstream around the primary conversion and intermediate absorptionsections, and introducing it directly into the secondary con-version section, results in energy savings by reducing amountof power required to transport the gas through the plant, andby increasing the amount of recoverable heat of reaction fromthe secondary conversion section.
