What is the difference between scavenging and supercharging?
Close the discharge ESD valve. The suction ESD valve shall remain in open position. The blowdown ESD valve shall remain in closed position. The antisurge valves and capacity control valve goes to open position.
The motor stops and the compressor settle out to suction pressure. The auxiliaries keep running.
Generally initiated on trips on process parameters. Enables faster start-up compared to ESD Emergency shutdown: The external seal gas supply shall be isolated by the ESD valve on the seal gas line.
The compressor blowdown valves shall open and depressurise the gas to flare. The suction, inter-stage s and discharge scrubbers low low level closes liquid outlet ESD valves. The inter-stage s and After-cooler fan high vibration shall trip the respective fan.
Low Low temperature at the after cooler outlet shall trip the first working fan at 30 deg C and the next at 20 deg C. External seal gas high high pressure downstream of external seal gas pressure letdown valve for LP casing shall close the external seal gas supply ESD valve.MECHANICAL ENGINEERING Interview Questions and Answers PDF free download for freshers Basic technical unit wise 2mark important lab viva class lecture notes.
Isentropic Expansion – Isentropic Compression for Ideal Gases An isentropic process is a thermodynamic process, in which the entropy of the fluid or gas remains constant.
It means the isentropic process is a special case of an adiabatic process in which there is . In thermodynamics, an isentropic process is an idealized thermodynamic process that is both adiabatic and reversible.
The work transfers of the system are frictionless, and there is no transfer of heat or matter. Such an idealized process is useful in engineering as a model of and basis of comparison for real processes.
The word "isentropic" is . The Thermodynamics of State IDEAL GAS The deﬁning equation for a ideal gas is Pv T An Isentropic Process for an Ideal Gas Given: Isentropic Ideal Gas, Compression/Expansion Isentropic implies a reversible and adiabatic process where s = constant. With an ideal gas.
Isentropic Expansion – Isentropic Compression for Ideal Gases. An isentropic process is a thermodynamic process, in which the entropy of the fluid or gas remains constant.
It means the isentropic process is a special case of an adiabatic process in which there is no transfer of heat or matter. Process Datasheet: Defines the suction and discharge conditions (P,T, Flowrate) and gas composition.
Main input to the compressor vendor. Define all possible options of suction and discharge conditions and gas compositions, present and future.
