Analysis of Compressor Control Structures and Algorithms for Compressor Drives for Automobile Gas Filling Compressor Stations

Geothermal Energy for Natural Gas Compressor Stations; an Environmental and Economical Assessment

Iran’s environmental condition is critical, since it is experiencing desertification, unsustainable development and overpopulation. The objective of this study is power source replacement in natural gas stations that operate with natural gas compressors, through using electrical motors, which can be fed by a 160 MW geothermal power plant, as an alternative to gas turbines. Application of such a...

Compressor Noise Control

Scheduling of Gas Turbine Compressor Washing

This paper describes an estimation method for gas turbine compressor degradation and an economical optimisation model for determining the optimal compressor washing cycles. The optimisation model aims at minimising fuel consumption and emissions in combined-cycle power plants. The results presented are of significant importance for power plants operators that have the possibility of frequently ...

Surge Avoidance for Compressor Systems

This tutorial explains the surge phenomenon as well as the precursors of surge and the damage that surge can cause to the equipment. Then, methods to keep the compressor system from surge, i.e., modern surge control systems, are discussed. This includes the necessary instruments, algorithms used, as well as the piping layout required. Sizing considerations for valves and other system components...

QRFXFreeze: Queryable Compressor for RFX

The verbose nature of XML has been mulled over again and again and many compression techniques for XML data have been excogitated over the years. Some of the techniques incorporate support for querying the XML database in its compressed format while others have to be decompressed before they can be queried. XML compression in which querying is directly supported instantaneously with no compromi...
