Recovery strategies

Product Recovery. Comparison of the electrochemical cell to a chemical reactor shows the electrochemical cell to have two general features that impact product recovery. CeU product is usuaUy Uquid, can be aqueous, and is likely to contain electrolyte. In addition, there is a second product from the counter electrode, even if this is only a gas. Electrolyte conservation and purity are usual requirements. Because product separation from the starting material may be difficult, use of reaction to completion is desirable ceUs would be mn batch or plug flow. The water balance over the whole flow sheet needs to be considered, especiaUy for divided ceUs where membranes transport a number of moles of water per Earaday. At the inception of a proposed electroorganic process, the product recovery and refining should be included in the evaluation to determine tme viabUity. Thus early ceU work needs to be carried out with the preferred electrolyte/solvent and conversion. The economic aspects of product recovery strategies have been discussed (89). Some process flow sheets are also available (61).

Determination of transmissivity can be useful in designing LNAPL recovery strategies because the rate of LNAPL recovery is a function of LNAPL transmissivity (Tn). 

An important parameter in understanding LNAPL distribution and development of a recovery strategy in unconsolidated deposits is understanding the sedimentary architecture, as discussed in Chapter 3. Initial development of lithofacies maps is fundamental to this understanding. 

To date, reports have involved palladium catalysts for Suzuki and Sono-gashira coupling reactions [63-66], rhodium catalysts for silylations of alcohols by trialkylsilanes [67,68], and tin-, hafnium-, and scandium-based Lewis acid catalysts for Baeyer-Villiger and Diels-Alder reactions [69]. Regardless of exact mechanism, this recovery strategy represents an important direction for future research and applications development. Finally, a particularly elegant protocol where CO2 pressure is used instead of temperature to desorb a fluorous rhodium hydrogenation catalyst from fluorous silica gel deserves emphasis [28]. 

Second, disaster situations represent real and potential threats to data integrity. Evidence of appropriate preventive action and recovery strategies must be presented, generally in the form of a disaster recovery plan with an annual practice drill. The disaster recovery plan is usually organized aroimd likely problems (flood from broken pipes, fire, electrical failure, etc.) and includes appropriate notifications, substitute activities, and recovery actions. The disaster recovery plan generally interacts with system backup, recovery, and archive SOPs. 

Nurses need to understand how the disaster recovery process can be used to maintain and enhance the quality of life. We need to design recovery strategies for enhancing quality of life, pursue new strategies for improving the quality of life, and institute systems for the ongoing monitoring of the quality of life.

Recent studies by Thermo Electron Corporation have shown that certain forms of waste heat utilization (e.g., recuperators or process steam boilers) provide a better return on investment than that obtainable from bottoming cycle generators. The optimum choice of heat recovery strategy depends, in part, upon the temperature of exhaust heat available.

Only a small number of the investigations summarized in this review addresses the obvious practical concern of mixed plastics waste. Higher performance products with multiple polymeric layers, the use of additives, fillers and colorants, and the expense of sorting individual polymers for subsequent processing all demand resource recovery strategies capable of handling a complex mixture of... 

Airworthiness of civil aircraft depends upon a process by which a team composed of aircraft manufacturers, regulators, and one or more airlines predicts possible system failures. This process. Maintenance Steering Group 3 (MSG-3), considers possible failure pathways (e.g., in structures, controls, avionics) and for each pathway determines a recovery strategy. For structural failure, this may be replacement after a fixed service life, regular inspection to ensure detection, or an indication to crew of the malfunction. The concern here is with the reliability of the primary failure recovery system for aircraft structural inspection regular inspection to ensure detection. 

Healthcare organisations need to have business continuity plans in place and hosting organisations need tried and tested disaster recovery strategies. The existence of these plans and policies can be used to support the safety case.
