Optimization of compressor stations

Computational optimization of gas compressor stations: MINLP models versus continuous reformulations

When considering cost-optimal operation of gas transport networks, compressor stations play the most important role. Proper modeling of these stations leads to complicated mixed-integer nonlinear and nonconvex optimization problems. In this article, we give an isothermal and stationary description of compressor stations, state MINLP and GDP models for operating a single station, and discuss sev...

Optimization Of A Rotaprocating Compressor

Optimization Of Screw Compressor Design

An optimisation procedure for twin screw compressor design is described, which is based on an analytical algorithm for rotor profile generation combined with a differential model of the fluid flow and thermodynamic processes within the machine. Rotor profiles are generated from a rack which have both stronger female rotor lobes and higher displacement. Compressors thus designed have higher deli...

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,...

Aerostructural Optimization of a Transonic Compressor Rotor

This paper presents a framework for multi-objective and multidisciplinary design optimization using highfidelity analysis tools. In this framework the aerodynamic performance is evaluated based on a Navier–Stokes equation solver, and the structure dynamics is computed using commercially available finite element software. We employ a genetic algorithm as a robust design optimization tool to faci...
