Plant Integration

TYPE	Description
Hints	Sequence: Block Diagrams-->Schematics-->PFDs-->P&IDs NOT after you have designed your individual Unit Op
What to do after Sem 1	Review Block Diagrams, Process Schematics, PFDs and P&IDs Check for mistakes/deficiencies as per "Common Mistakes" You may have opportunity to revise PFDs and P&IDs for your individual Unit Op in line with Block Dia / Schematics / PFDs / P&IDs
Examples	Perform Pinch Analysis to minimise external heating and cooling requirements Develop Heat Exchanger Networks where one unit is not sufficient Mass Exchange: Pay attention to "feed from" and "to" streams: Ensure correct stream specifications (pressure/temperature/composition) to next Unit Op Add recycle stream(s) to optimise yields Add waste / vent / flare streams Show required control (final control devices and control loops) for combined/integrated process - eliminate unnecessary/conflicting process control loops Show planned future equipment/systems/unit ops e.g. compression facilities in offshore O&G Production to cater for declining reservoir pressure Show OSBL (Outside Battery Limits) in addition to ISBL (Inside Battery Limits) facilities where appropriate
