摘要

This paper discusses the development and application of a whole plant simulation and control systemfor simultaneous optimization of processes and assets. It overcomes several limitations in DistributedControl Systems (DCS) and SCADA systems, as implemented today in ENR plants for localoptimization of secondary treatment, tertiary treatment and solids handling. It does so by placing awhole plant optimization system that is asset based as an operating layer on top of local optimizationroutines, thereby enabling global optimization of asset usage over time and operation across the wholeplant. The system can be implemented to provide intelligence to DCS to improve and optimize theoperation based on current condition of assets and the availability of tanks in each part of the plant.Additionally, it provides intelligence to asset management software to help prioritize corrective andpreventive maintenance, based on real time computation of risk and risk reduction through redundancyfollowing optimization. The mathematical techniques for solving linear and non-linear partialdifferential equations associated with biochemical and physico-chemical reactions in tanks wereupgraded to improve their accuracy to reflect actual operating conditions as measured with sensors andto improve their speed to run over 100 optimizations of the whole plant within one minute.Implementation of the tools can help the plant improve compliance, especially during periods when theplant is subjected to stresses from wet weather flows and extreme temperatures. In the long run, theUtility is able to manage its plant at lower operating, maintenance and life cycle costs while meeting itspermits.
