Dynamic
Simulation of a Gas Liquifying Unit |
KOC/SKEC |
A
compressor system with 3 stage groups is used to compress evaporated gas from
a tank system and separate most of the hydrocarbons into liquid form. Due to
changes between summer and winter and property of the gas, the molecular
weight can vary in wide ranges. Opening of the compressor anti-surge valve
changes the molecular weight of the HP compressor instantaneously. Advanced
control strategies had to be developed to cope with this operation |

|
Dynamic
Simulation of a multi stage group axial flow compressor system |
Sasol |
A three
stage group axial flow compressor with two intercoolers is dynamically
simulated. The aim of this model is to compare measured performance data
versus simulated data and identify performance degradation from this
comparison. |

Air separation unit |

A full
air separation unit, consisting of Main Air Compressor, Booster Air
Compressor, Driver Steam Turbine, Coolers, Cold Box, Expansion turbine and
Booster Compressor along with other process equipment are dynamically
simulated to prove stable operation under normal operation and upset conditions.

Ethylen compressor system |
MAN TURBO |
A three

refrigeration process is dynamically simulated.. |
|
|
|
Gas Gathering station |
SKEC/ADCO |
Gas is
collected from a number of trunk lines and compressed in a compressor station
comprising of three compressors and then forwarded to a number of trunk lines
for further treatment. Basic process requirement is that the ratio of outlet
trunk flows is the same as inlet trunk flows. The
entire station including incoming and outgoing trunk lines was simulated.
First simulation runs showed that the overall control concept included a basic error. A modified
control concept was developed by Dr.-Ing. Blotenber Turboservice and
introduced to SKEC and ADCO. This modified control concept was then
implemented. |

Repeat
of a Dynamic Simulation of a Compressor Train with Steam Turbine and
Generator and Axial Flow Compressor feeding a chemical plant |
BASF |
This simulation study was originally made in 2002.
Process conditions have changed by 2010. Thus this study was repeated. In a
first phase, several process upsets which the plant has been exposed to were repeated. In a second phase, the control sequence was
updated and and the simulation runs were repeated
with the modified control concept. The operation of the plant was significantly
changed through this improvement. |
