Optimizing Product Quality Performance

The goal is to continually provide product quality that meets customer needs and expectations at a price they are willing to pay and a manufacturing cost/unit that generates maximum economic return.

Optimize product quality performance to generate maximum economic return... 

One important possibility to examine, analyze, and improve machining processes is the modeling and simulation. Using this technique the performance of cutting processes and characteristics of manufactured components can be predicted and planned in order to optimize productivity, quality, and cost (Tapoglou and Antoniadis 2012 van Luttervelt et al. 1998). 

The maximum economic return from a distillation column can be achieved by minimizing variability and optimizing the quality performance between the distillate and bottoms streams (Figure 7.6). The optimum DNS for a product being sold is usually in the range of 3.0 to 3.5o. The optimum DNS for a stream that is being recycled back in the process is usually in the range of 1.5 to 2.0o. 

Characterizing FCC feed provides quantitative and qualitative csti mates of the FCC unit s performance. Process modeling uses the feed properties to predict FCC yields and product qualities. The process model should be used in daily unit monitoring, catalyst evaluations, optimization, and process studies. 

Contrary to the commodity chemical business, the key to win in the specialty products market does not lie in squeezing out profits by means of economies of scale or process optimization. Rather, it lies in the ability for fast new product launches in order to capture the largest market share as soon as possible. Since superior product quality and performance is what really differentiates one specialty product from another, the product properties need to be adjusted as required by business needs. For example, the ability to manipulate functional chemicals in detergent products such as enzymes and zeolites, as well as backbone chemicals like surfactants, is often the key to success for both the detergent manufacturers and chemical suppliers [3], This trend has created an urgent need for an efficient and effective product and process development for these products. 

Like all other animals, poultry require five components in their diet as a source of nutrients energy, protein, minerals, vitamins and water. A nutrient shortage or imbalance in relation to other nutrients will affect performance adversely. Poultry need a well-balanced and easily digested diet for optimal production of eggs and meat and are very sensitive to dietary quality because they grow quickly and make relatively little use of fibrous, bulky feeds such as lucerne hay or pasture, since they are non-ruminants (have a simple stomach compartment). 

Control objectives for a chemical process originate from certain regulation tasks (i.e. product quality control, material balance control, safety, environmental regulations, etc.) and economic objectives (i.e. optimizing the economic performance). Such a classification of control objectives automatically formulates the different design activities for the regulatory and optimizing control structures. 

The use of composite catalyst fillings is the industrial standard when treating resids in a modem refinery. The grading can be made both with respect to size, shape and catalyst properties in order to optimize the performance, obtain the desired product quality and the longest catalyst life. The optimization is often a careful balancing of catalyst deactivation and performance, and it is therefore important to understand the mechanisms of deactivation. For this reason, a brief introduction to the various aspects of catalyst deactivation will be given what deactivates the catalysts and how is catalyst deactivation generally tied in with catalyst properties ... 

Aquaculture in ponds and other enclosures, and mariculture in enclosures in seawater, produce shellfish, crustaceans and fish for human consumption. It is therefore of vital importance (for the organisms and for the consumers) that the water quality is optimal, and regular testing is essential to prove that pollution is absent. BEWS are very suitable to carry out this task, as several test organisms belong to the same group as the cultured species mussels, oysters, clams and fish. There seems no reason why other BEWS could not perform in freshwater aquaculture systems as well. BEWS not only monitor the quality of the ambient water in aquaculture farms, but may also be used to optimize production. Stressed animals are less productive in terms of e.g. growth...
