While process design and equipment specification are usually performed prior to the implementation of the process, optimization of operating conditions is carried out monthly, weekly, daily, hourly, or even eveiy minute. Optimization of plant operations determines the set points for each unit at the temperatures, pressures, and flow rates that are the best in some sense. For example, the selection of the percentage of excess air in a process heater is quite critical and involves a balance on the fuel-air ratio to assure complete combustion and at the same time make the maximum use of the Heating potential of the fuel. Typical day-to-day optimization in a plant minimizes steam consumption or cooling water consumption, optimizes the reflux ratio in a distillation column, or allocates raw materials on an economic basis [Latour, Hydro Proc., 58(6), 73, 1979, and Hydro. Proc., 58(7), 219, 1979].

In Science in Action, Bmno Latour defines an instmment or inscription device as any set-up, no matter what its size, nature and cost, that provides a visual display of any sort in a sdentific text (1987, 68). Instruments, he argues, provide an other world just beneath the text —a world that is invisible as long as there is no controversy (69). Both the instruments and the visual...
