Enthalpies and enthalpy transfers
Sulfuric Acid Manufacture, 2013Co-Authors: Matthew J. King, William G. Davenport, Michael S. MoatsAbstract:Catalyst Bed Input and output gas enthalpies are readily calculated with this book’s heatup path-equilibrium curve intercept worksheets. These enthalpies are conveniently used to calculate the amount of heat that must be removed to cool a Catalyst Bed’s output gas to a specified temperature. The heat removal quantities (plus first Catalyst Bed feed gas Input rate) are readily used to determine the cooling requirements (MJ/h) of all the acid plant’s gas cooling devices. This information is used ( Chapter 22) to show how Catalyst Bed and H2SO4 making Input gas temperatures can be controlled by bypassing gas around the cooling devices.

Three Catalyst Bed acid plant
Sulfuric Acid Manufacture, 2013Co-Authors: Matthew J. King, William G. Davenport, Michael S. MoatsAbstract:This chapter evaluates how SO3, CO2, SO2, and O2 concentrations in feed gas, Catalyst Bed pressure, and Catalyst Bed Input gas temperature affect maximum catalytic SO2 oxidation efficiency. Only Input gas temperature has a significant effect. Cool Input gas (but warm enough for rapid catalytic SO2 oxidation) gives highly efficient SO2 oxidation. Warmer Input gas gives less efficient oxidation. The chapter also evaluates the book's assumptions. The major assumptions of no heat loss and nonattainment of equilibrium cause small offsetting effects.

Optimum Double Contact Acidmaking
Sulfuric Acid Manufacture, 2013Co-Authors: Matthew J. King, William G. Davenport, Michael S. MoatsAbstract:Double contact acidmaking is more efficient than single contact acidmaking. This has made it the most used industrial process. The reason for its high efficiency is its efficient oxidation of SO2 in its after-H2SO4-making Catalyst Bed(s). The most efficient double contact plants have one Catalyst Bed after H2SO4 making, remainder before. 3-1 plants are more efficient than 2-2 plants. 4-1 plants are more efficient than 2-3 and 3-2 plants. Cool Catalyst Bed Input gas gives high SO2 oxidation efficiency in single and double contact acid plants. Low deactivation temperature cesium Catalyst is beneficial in this respect. Cesium Catalyst is costly, so many acid plants use it in only one Catalyst Bed. From the SO2 oxidation efficiency point of view, it is best used after intermediate H2SO4 making.
