Auto-Select Control System

Each part of the system has its own feedforward-feedback system. The final concentrating process does not require feed concentration compensaton so that it is only necessary to establish the ratio of steam to feed and adjust the ratio by feedback. Ordinarily, the system is paced by the final concentrator feed signal which is fed to the auto-select system. The final concentrator controller output manipulates the feed to the intermediate process so as to maintain the final concentrator feed at the set point limit.

The median flexibility and control results are presented in Figure 11.8. The operators surveyed rated the system as inflexible for a number of criteria, including the presence of a Redo functionality, the presence of shortcuts, autofiU facilities, manual/ auto select, file naming, and personalization. It should be noted that this usability questionnaire is generic to all software. It is therefore highly reasonable that some of the functionality is correctly omitted from the SCADA system.

The reactions that occur to auto-exhaust emissions when exposed to plasma include oxidation of HCs, carbon monoxide, and partially diesel PM also. Nitric oxide (NO) can be oxidized by plasma to N02. Plasma alone, due to its oxidizing character, is not a viable NO control method. However, combinations of plasma with catalysts, referred to as plasma-assisted catalysts or simply plasma catalysts , have been suggested for NO reduction. The plasma is believed to show potential to improve catalyst selectivity and removal efficiency. Current state-of-the-art plasma catalysts have efficiencies comparable to those of active DeNO systems, removing about 50% of NO at a fuel economy penalty of less than 5% [85],...
