Abstract
Abstract Characteristics of sulfuric acid solutions encountered in refineries, the types and kinds of containers, piping, valves, heaters and other equipment used to handle it are considered by the authors with respect to their corrosion resistance and certain other related qualities. Materials of construction for construction, fabrication and design details of the various vessels and equipment are discussed with relation to the several concentrations, temperatures, pressures, velocities and other peculiarities of the sulfuric acid solutions encountered in petroleum refineries. Results of field experience and laboratory tests are reported and recommendations are made respecting the selection of materials, optimum design, expected service life, maintenance procedures and economic considerations with respect to many materials. Precautions to be taken with welded and riveted tanks, fabrication and design considerations related to lead and other linings; examples of good and bad service and reasons for failures for containers, pipes, valves, pumps and heater coils are given. Galvanic effects encountered in connection with certain equipment are reported and remedial measures recommended. Figures showing examples of failures and charts and tables of data are included.
