Economic Performance Indicator Based Optimization for the Air Separation Unit Compressor Trains

Analysis of Screw Compressor Performance Based on Indicator Diagrams

Optimization of Compressor Design Including Economic Factors

A new approach to choosing the optimum design of reciprocating compressors is discussed. Economic criteria ore included together with optimisation procedures which account far thermodynamic criteria of performance, These procedures are applied to a mathematical model of a compressor to produce a "best" design. Such factors as initial cost, interest rates, depreciation, inflation, running costs,...

In this case, hospitals are considered as the important and final stage of health service supply chain. Consequently, quality of health services offered by hospitals has a straight impact on the safety of individuals. Methods: </st...

Application of the Economic Elasticity Concept to Compressor Performance Parameters

Offset-free Nonlinear Model Predictive Control Based on Moving Horizon Estimation for an Air Separation Unit

Air separation units (ASU) pose a classic problem for nonlinear system control. This paper proposes a framework that integrates nonlinear model predictive control (NMPC) and moving horizon estimation (MHE). We prove that the proposed method achieves offset free regulatory behavior, even in the presence of plant-model mismatches. If the plant uncertainty structure is known, the proposed framewor...
