Table 9.1. Sensors and adjustments for controlling H2SO4 making packed tower. All sensors are placed in ceramic shield tubes to prevent corrosion. Table 9.1. Sensors and adjustments for controlling H2SO4 making packed tower. All sensors are placed in ceramic shield tubes to prevent corrosion.
Output acid temperature is controlled by adjusting the H2SO4 making tower s ... [Pg.105]

Acid circulation through the H2SO4 making tower is continued during plant shutdowns. This maintains controlled corrosion conditions in pipes, pumps, coolers and the H2SO4 making tower. [Pg.106]

Most of the mathematical chapters analyze catalytic S02+ /202—> SO3 oxidation in single and double contact acid plants. The remainder examine temperature control and H2SO4 making. [Pg.118]

These values pave the way for Chapter 22 s examination of catalyst bed and H2SO4 making temperature control. [Pg.235]

The next chapter builds on this information to show how catalyst bed and H2SO4 making input gas temperatures are controlled by bypassing gas around the cooling devices. [Pg.242]

As mentioned in Chapter 5, MnS04 solution can be electrolyzed to Mn02 and H2SO4 in a closed loop cycle and recycled to produce T nra-anisic-aldehyde from PCME. There will be no waste streams in this process and only make up quantities of H2SO4 will be required. However, the oxidation process has to be controlled carefully. [Pg.182]
