Reaction rates and product yields are closely related to the operating
temperatures at which processing is conducted. As a matter of fact, the accurate
regulation of temperature level has been of great practical importance since the
early days of our industry. The advent of thermal cracking processes made the
close control of relative furnace outlet temperatures a vital matter to refiners.
Further development of such conversion processes tended to an operation at
higher temperatures ...

This is the only correct use of control charts — as a maintenance tool, not as a
problem- solving tool." While Bhote is fundamentally correct, if we are to wait for
all the engineers in the world to design our products and processes with narrow
variation and then for manufacturing and quality personnel to maintain that
variation using control charts, we will never succeed in whittling away the
problems. Fundamentally most industries are so far away from the ideal state that
Bhote uses as a ...

A plant with multiple aeration basins will serve as an example of a stability
problem. A frequent problem when changing air flow to one section of a process,
or when changing the total air flow, is production of an imbalanced air flow. For
example, in many large activated sludge plants, there are parallel aeration
basins. Small differences in influent wastewater or recycled sludge-flow rates can
produce imbalanced DO concentrations; the control system will then attempt to
correct the ...
