Production processes, product flexibility

When surfactant-coated glass fibers are included to improve product flexibility and reduce thermal expansion, these semibatch processes are termed reinforced reaction injection mol ding (RRIM).

Extend Range of Feedstocks for the Process. Feedstock flexibility can enable maximum advantage to be taken of market fluctuations in the price and availability within the range of feedstocks which can be used. Obviously this is inappropriate in some cases where there is a close chemical link between feedstock and product, e.g. direct oxidation of ethylene to ethylene oxide, but in some processes, e.g. steam-reforming, flexibility is possible and may be advantageous.

In order to enhance production flexibility and to take advantage of different feedstock pricing patterns, chemical plants in some productive segments or product lines are designed to use a variety of alternative process inputs to produce a variety of products. Although economically attractive in a narrow production sense, such... 

It is the author s opinion that the method of oxidation in the oscillation-kinetic mode gives an opportunity to resolve effectively the problem of establishing chemical processes that can be flexible and capable of being adjusted to the manufacture of different products in a very short time. Recently, production flexibility has been associated with flexibility of... 

The modern methods of three dimensional microfabrication have lead to the development of extremely miniaturized chemical and biotechnological systems. These so called microreactors represent novel approaches in respect of production flexibility and chemical reactions not yet applied in chemical processing. This has stimulated world-wide research in this field so that the technical feasibility of such devices has been demonstrated in the laboratory scale. 

The processes are flexible and efficient and the alpha olefin products from the SHOP unit can be reacted in either the SHOP I/D unit or in the hydroformylation process depending on which is most desirable. This then avoids the problem of low value byproducts.

Primers can be used to protect both treated metal and nonmetal substrates after surface treatment. The use of a primer as a shop protectant may increase production costs, but it may also provide enhanced and more consistent adhesive strength. The use of a primer greatly increases production flexibility in bonding operations. Usually primer application can be incorporated as the final step in the surface preparation process. The primer is applied as soon as possible after surface preparation and usually no more than a few hours later. The actual application of the adhesive may then be delayed significantly. 

According to the principle of dynamic adaptation (Likhtenshtein, 1976a), the multi-orbital interaction between a substrate and metal atoms in a bi- or polynuclear center and the consequent chemical conversion require a certain optimum flexibility of metal atoms involved in the catalytic process. Such flexibility would allow the space provision for each step of the consecutive chemical reaction, i.e. complexation, product formation and release. 

Calendering and extrusion lines (Chapter 5) produce film, sheet, and for applying plastic coatings to textiles, paper, or other supporting material. Table 9.1 provides comparison in fabricating PVC film. The extrusion process provides flexibility, when compared to calendering, that includes ease of changing product thicknesses, widths, materials, and provides for short production runs.

The hydroisomerization step features complete C4 acetylenes and butadiene conversion to butenes, maximum 2-butenes production, flexibility to process different feeds, polymer-free product and no residual hydrogen. The second step separates isobutylene either by conventional distillation, or by reacting the isobutylene with methanol to produce MTBE. 

The process is flexible. Ethylene to propylene product weight ratio can be modified between the range of 0.75 to 1.5 by altering reactor operating severity. The total yield of olefins varies slightly throughout this range.

Diffusive and convective transport processes introduce flexibility in the design of catalyst pellets and in the control of FT synthesis selectivity. Transport restrictions lead to the observed effects of pellet size, site density, bed residence time, and hydrocarbon chain size on chain growth probability and olefin content. The restricted removal of reactive olefins also allows the introduction of other intrapellet catalytic functions that convert olefins to other valuable products by exploiting high intrapellet olefin fugacities. Our proposed model also describes the catalytic behavior of more complex Fe-... 

The process flow diagram for an automatic bakery shortening system is shown in Figure 21. The heart of the processing system is a standard A and B unit combination. A C unit can be added after the B unit for additional temperature control, crystal stabilization, and product flexibility. Shortening from the B unit is transferred to and held in agitated, jacketed tempering tanks until properly...
