Sources and strategies

An existing method may have a sufficiently good fit that adaptation is likely to lead to a suitable method. This relies upon professional knowledge and experience. 

For methods that are likely to be widely used, other aspects of suitability need to be considered. 

Can the method be written down sufficiently clearly and concisely to allow ease of transfer  

Can all the critical method parameters be identified and controlled This is particularly important where automated systems are involved. 

Is the equipment readily available to all the likely participants This assumes a special importance for internationally distributed methods and may involve questions of maintenance and support.

Some of the most important document types containing device information include patents, market reports, conference proceedings, analyst reports, venture capital reports, and association publications. The following sections of this chapter will include discussions of specific sources and strategies to address these information challenges.

Both control schemes react in a similar manner to disturbances in process fluid feed rate, feed temperature, feed composition, fuel gas heating value, etc. In fact, if the secondary controller is not properly tuned, the cascade control strategy can actually worsen control performance. Therefore, the key to an effective cascade control strategy is the proper selection of the secondary controlled variable considering the source and impact of particular disturbances and the associated process dynamics.

In the stratification strategy the supply air is used to substitute the outgoing air from the ventilated (in most cases occupied) zone, thus preventing circulation patterns between the zones. The supply air has to be distributed in such a way that the buoyancy flows are not disturbed. Exhaust air openings are to be located downstream in order to avoid reverse currents within the room. The location of the contaminant sources and the heat sources causing density differences must be the same in order to carry out the contaminants with equal or higher density than air. 

Local extract A ventilation strategy whereby heat, steam or contaminants are captured at source and ducted to discharge outside the space. 

Determination of environmental carcinogens is not an end in itself. Although often misunderstood or misinterpreted, the aim of scientific work in this area is to collect data on human exposure, to pinpoint emission and immission sources and to determine the causes of potential health risks to humans. The ultimate aim is always elimination or reduction of human exposure and thereby prevention of human cancer. In view of the slow progress in the treatment of human cancer this approach is an important strategy in the fight against this disease.

The reactivity of Ti02 with alcohols is important in a number of technological applications. For example, alcohols can be used as energy carriers in renewable sources and they are also employed as model pollutants so that environmental cleaning strategies can be tested. 

Current C02 capture technology (first generation) is adapted from gas separation processes already in industrial use. There are several technologies and strategies to capture C02 from stationary sources pre-combustion, post-combustion and oxy-fuel (Figure 2).
