Capacity adjustment

Tactical planning lays out a step by step approach for the implementation of the strategic objectives with a time horizon of 1 to 3 years. Typical decisions include the launch or discontinuation of specific products, production capacity adjustments and product transfers within the existing production network. 

Commercial plants Twenty-three reaction lines with different capacities, adjusted to the market conditions, are in operation or under construction. Nearly 2.9 million tpa of HDPE are produced with the Hostalen technology.

The ability of suppliers to have a portfolio of customers enables flexibility of the supply base to absorb downturns in individual OEM volumes, thus providing the capacity adjustment flexibility for the OEMs. In addition, the ability for the base of smaller companies to easily adjust their production capacity by working longer hours and so on provides the ability to rapidly adjust upwards to demand increases. 

As is the case for the pH level and buffer capacity, adjustment of osmotic value to physiological conditions is advisable. Sodium chloride or glucose are mostly used to adjust tonicity of parenterals. Sometimes deviating medical requirements are to be met. For example, hyperbaric solutions of local anaesthetics are used in spinal anaesthesia (see Sect. 13.2.4). Hyperbaricity in comparison to the cerebrospinal fluid is achieved by a high glucose concentration (7.5 %) which is also a hyperosmolar. 

The value of decision parameters is not greater than the upper bounds and not smaller than O. Thus, in this study, the feasibility has been checked based on the productivity and raw materials inventory capacities. Adjust each solution in the offspring set Qto make it feasible. For example, all decision parameters must be nonnegative and within the boundaries. If the solution is infeasible, the solution has to be re-thought, for example, force the parameter to take the upper bound or the lower bound of the feasible interval. 

With heat capacity adjustment for T change may apply to N62. 

In order to carry out a distillation, the apparatus is completely assembled, the water pump turned on to its maximum capacity, and the screw clip on the capillary tube in the Claisen flask adjusted so that a gentle stream of air bubbles through the liquid (see Section 11,19 for details of the preparation of the capillary tube). The barometric pressure is read, and if the resulting vacuum deter mined from the reading on the mano meter is satisfactory (as estimated from the temperature of the tap water), the flask may be heated in an air (Fig. II,... 

One of the simplest ways to improve resolution is to adjust the capacity factor for solute B. If all other terms in equation 12.21 remain constant, increasing k improves resolution. As shown in Figure 12.11, however, the effect is greatest when the... 

Adjusting the capacity factor to improve resolution between one pair of solutes may lead to an unacceptably long retention time for other solutes. For example, improving resolution for solutes with short retention times by increasing... 

Assemblies of small disks are rotated in a planetary movement around a central screw conveyor. The disks are mounted on six hoUow axles and the axles revolve on overhanging bearings from the gearbox at one end of the vessel where they are driven, via a drive shaft, by an electric motor. The filtrate is collected from the disks via the hoUow shafts and a filter valve into a large collecting pipe. The hoUow shafts also collect the water and air from the dewatering process, in another part of the rotational cycle. The number of disks mounted on the shafts can be adjusted for different materials, depending on the required capacity and the cake thickness to be used. 

Reciproca.ting Piston Meters. In positive-displacement meters of the reciprocating piston type, one or more pistons similar to those in an internal-combustion engine are used to convey the fluid. Capacity per cycle can be adjusted by changing the piston stroke. 

A homogenize is a high pressure positive pump with three, five, or seven pistons, that is driven by a motor and equipped with an adjustable homogenizing valve. Smoother flow and greater capacity are obtained with more pistons, which force the product iato a chamber that feeds the valve. In design and operation, it is desirable to minimize the power requirements for obtaining an acceptable level of homogenization. At 17.2 MPa (2500 psi) and a volume of 0.91 t/h (2000 lb/h), a 56-kW (75-hp) motor is required.
