Operators Kappa

All clinically used opiates have the same pharmacology since they all act on the mu receptor with the exception of the kappa agonist, pentazocine. Opiates are used to relieve moderate to severe pain whatever the cause (accidents, post-operative pain, cancer, etc.) and are used pre-, intra- and post-operatively. The mu opiates differ only in potency and pharmacokinetics. Examples are ... 

The long warm up period contributes little to the H factor because reaetion kinetics dictate that the rate of delignification more than doubles for every 10°C rise in temperature. The equation is useful as it allows mill operators to determine when to stop the cook even though the operating temperatures have differed from normal, for example because of fluctuations in steam supply to the digesters. Operators merely have to ensure that they cook to a constant H factor (Figure 13.12b), as pulps eooked to the same H factor have essentially the same properties, i.e. yield, lignin eontent (kappa number). Results can be compared provided the initial alkali and sulphidity eoneentrations are the same. 

Considerable interest has been shown in the use of anthraquinone in wood pulping operations. The optimal yield of pulp and pulp viscosity at a given Kappa number was obtained with 0.25 M-NaOH. The rate of delignification was... 

It is clear that only the adaptive scheme achieved to drive the system to the desired set point, while the non-adaptive scheme became unstable, obviously due to the inadequacy of the non-adaptive model to approximate successfully the kappa number dynamic behaviour in the new operating region. A second test case was then examined, where the the R coefficient matrix was set equal to [3 3]. The responses of both closed loop systems are shown in figure 3b. Though this time the performance of the non-adaptive MFC was substantially improved, the superiority of the adaptive scheme is still clear, since it reaches the desired set-point in much sorter time.

Where a contractor operates a facility dedicated to Kappa, the standard shall apply to ... 

In-mill Mixing Assessment. Mixing assessment in mill operations must be done in a manner that does not upset the process or compromise pulp quality. Past techniques have used mixing quality indices (i.e., pulp brightness, kappa number, etc.) (Atkinson and Partridge, 1966 Elliott and Farr, 1973 Abercrombie, 1986 Cameron, 1987), residual chemical profiles (Paterson and...
