This course provides a comprehensive understanding of ethylene compression related to compressors technology, operation and efficiency.
Public :
Engineers and technical staff (operation, maintenance and/or engineering) interested or involved in ethylene compression.
Level : Skilled
Prerequisite :
To fulfill at least one of the following criteria:
to have a proven professional experience of 1 year related to the operation of an ethylene polymerization unit,
or to be in the process of moving towards a technical position related to the operation of a PE unit.
Duration : 1 Day
Ideal gas equation and implementation; isentropic compression; mass and volume capacity. Supercritical gas behavior. Practical compression laws: discharge temperature, power of compression. Pressure-enthalpy diagram for ethylene: for primary compressors and hypercompressors. Main limitations: risks of condensation, overheating, decomposition, grease deposits. Case studies: ethylene compression from 1 to 3000 bar.
Duration : 1 Day
Indicator diagram for ideal and actual cases. Influence of process temperatures and pressures. Dead volume: impact on the intake of the machine. Capacity control: different methods. Power, efficiency. Behavior of multistage reciprocating compressors. Typical troubleshooting. Operation: start-up and shutdown difficulties. Cases studies: industrial ethylene compression, troubleshooting.
Duration : 1 Day
Compression ratio limitation due to axial loads on the crankshaft. Interstage pressure control, risk of rods overbendings or plunger/seals breaks. Discharge temperature limitation due to decomposition and oligomer deposits. Lubrication operation and survey: crankshaft, oil seal and cooling. Criticity of the oil type. Machine safety - PROGNOST™ type monitoring: axial vibrations, rod drop, oil temperatures and pressures, process temperatures and pressures. Typical defaults, solutions and diagnosis. Cases studies: various cases of troubleshooting.
Duration : 0.5 Day
Main components: frame, cylinders, piston, piston rings, piston rod, crankhead, crankshaft, distance pieces, valves, rod seals. Auxiliaries: pulsation dampeners, crankshaft, seals and cylinder lubrication systems, cooling systems, safety devices. Capacity control technology: main components (unloaders, clearance pockets). Application: various compressor parts demonstrations.
Duration : 0.5 Day
Main differences with classical reciprocating compressors. Hypercompressor description: valves, cylinders, seals. Auxiliaries: Construction and survey. Crankshaft lubrication. Rod seal lubrication. Oil seal and cooling. Drains.
Attendees will be able to implement the following skills:
Recognize ethylene compressor and hypercompressor technology,
Explain the compression of gases in hypercritical mode and the method of pre-dimensioning these machines,
List the monitoring points provided on these machines and the related operations,
Identify the typical failure modes of these machines, their causes, and associated remedies.
Study of actual cases based on industrial situations.
