Duty, changes

Persons who have passed the Medical Representatives Examination whose duties change so as to become those specified in Clause 16.3 as being appropriate to the Generic Sales Representatives Examination are exempt from the need to take that examination. 

In a simplified approach we consider a separation section where all the units are lumped in a black-box. The composition of the outlet streams is constant due to the local control. In practice, this is achieved by manipulating internal flow rates or by heat duties. Changing the flow rate or composition of the inlet streams is reflected by a gradual change of the flow rate of outlet streams. When complete reactant recovery is assumed (z4 = 0), the simple model describing the dynamic behaviour of the recycle consists of a first-order differential equation ... 

The retrofitting of an existing plant is often undertaken as an alternative to installing a new column when the required duty changes. This may call for ... 

Capture the same other information as a paper log (carrier name, date, equipment numbers, duty changes, shipment number, etc.).

This is not to imply that the transition from rear area to forward area operation was easy and uncomplicated. There were lessons to be learned by both the supporting and the supported units and tactics and techniques had to be developed for the rather radical change of arenas. Not the least challenge was the need for smoke troops, whose duties changed almost overnight from rear support to action in the foremost areas of the combat zone, to adapt themselves to their new role. 

Finally we examine the effect of changing the reboiler duty. Table 13.9 summarizes the six simulation results with the reboiler duty changing from 0.14 to 0.19 GJ/h with 0.16 GJ/h as the base case. The compositions of the decanter organic phase, aqueous phase, and the bottom are all the same with the varying of the reboiler duty. The recovery percentages of the acetic acid, water, and the entrainer (vinyl acetate) are also the same, no matter of what reboiler duty is used. As expected, the total batch time decreases as the reboiler duty increases. 

Figures 14.10 and 14.11 show how a number of variables change for disturbances in feed flowrate and feed composition. The output signal from the composition controller (OPCC) changes the setpoints of the temperature controllers on the last three heaters (TC3, TC4, and TC5) and the corresponding heat duties change (Q2, Q3, and Q4). The setpoints of the temperature controllers on the first two heaters (TCI and TC2) are constant at 371 K, but their heat duties change as the load changes. Figure 14.10 shows that none of the last three heat exchangers saturate at zero for the 20% decrease in feed. If only the last two...

In addition to the four-line grid graph and the location of all duty changes the log must also include ...

You must provide hazcom training at the time yoiu employees are initially assigned to their jobs, when a new chemical hazard is introduced into the work area or when the employee s job duties change such that he or she is now exposed to a hazardous chemical.
