PULSATION ANALYSIS OF PIPING NETWORKS The service is provided to gas compression systems and pumping systems manufacturers and is performed by the applications ACUSYS and ACUSCOMP.

Example # 1 – Analysis of the pulsations induced by a screw compressor on its delivery pipeline

DYNAMIC SIMULATION OF NATURAL GAS COMPRESSION AND LNG PLANTS The service is provided to gas compression systems manufacturers and is performed by the application COMPSYS.

Example # 1 – Optimisation of the admittance of a gas compression station hot by-pass line performed by the BFGS algorithm.

Example # 2 – For the emergency shut down of a gas compression train, it is found the flare valve opening sequence which prevents surge conditions and involves a driver coast down time compatible with lubricant oil reserve.

Example # 3 – For the start up of a gas compression train driven by an asynchronous electric driver, it is found the induction voltage sequence that avoids driver torque saturation conditions.

Example # 4 – During the start up procedure of a gas compression station, interferences between the performance controllers and the surge protection systems are highlighted. These are solved by modifying the controllers enabling speed level.
