Expansion.

Debottlenecking (to boost production by remedying/removing the problems/constraints withpiece of equipment/process that create more efficient or make it workable).

Modification of the existing plan:-

Thermal duty of heat exchangers.

Compressor for new gas composition = by equipment supplier.

Distillation column trays for new gas/liquid traffic = by equipment supplier.

Verification of:

Suitability of equipment + piping for new tem + pressure conditions.

Hydraulic calculations of pipework given the new flow conditions.

Control valves + pressure relief valves to be checked to have adequate capacity to cover the n

operating requirements.

Change of operating conditions for process equipment -> The duty must be checked for new condi

e.g.

New unit is added to the existing facility = will use some existing facility utilities (fuel gas, electrical

power, cooling medium, instrument air ) = need to verify.

Some require existing facilities to be shut in = to work to minimize.

Some can be done while the plant is in operation.

Connections of the new facilities to the existing plants = tie-in's (pipework, electrical power distrib
