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...

Abstract Because of the increasing demand for energy in recent period, it has become necessary to intensify study field evaluating performance gas station under first and second laws efficiency. The exergy losses stations are represented by compressor, combustion chamber, turbine. Therefore, this work aims analyze a 55 MW Taza power station. investigation demonstrated that most significant misf...

Wan Carbon capture and sequestration (CCS) is an important option for CO2 mitigation and an optimized CO2 pipeline transport system is necessary for large scale CCS implementation. In the present work, a hydrodynamic ...

The article is dedicated to the analysis of influence seasonally changing ambient temperature on technological parameters compression process at a gas turbine compressor station for transportation natural and associated collected from oil fields by an offshore subsea pipeline. As result analysis, indicators suction discharge pressure, capacity, during summer winter months were each stage multi-...

Management of compressor degradation is often considered from the perspective maintenance compressor, but most frameworks for operation compressors do not take into account. This paper proposes a method that takes account current level in order to manage further degradation. The algorithm can be used planning frameworks, particular if timings activities are fixed. extend lifetime by mitigating ...

The intensive development of gas transport and compressor manufacturing aimed at increasing the unit capacities pumping units, creating high-flow centrifugal compressors, productivity shops has led to appearance fundamentally new problems in diagnosis industrial pipelines. reasons for premature failure piping manifold stations can be associated with both high static voltage pipelines a level vi...
