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 :
Provide evidence of a professional experience of at least 1 month related to the concerned field.
ETHYLENE BEHAVIOR DURING COMPRESSION
-
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.
PRIMARY COMPRESSORS BEHAVIOR & OPERATION
-
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.
HYPERCOMPRESSORS BEHAVIOR & OPERATION
-
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.
TECHNOLOGY OF PRIMARY COMPRESSORS
-
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.
TECHNOLOGY OF HYPERCOMPRESSORS
-
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.
Upon completion of the course, the participants will be able to:
explain how to monitor and optimize the performance of compressors,
identify most common failure modes and corrective measures.
Study of actual cases based on industrial situations.
