IGL was commissioned to review the design and operation of the
Hydrofiner No. 2 plant and the Propane De-Asphalting Unit.
In both cases the method of approach was similar.
Current plant operating performance was determined by conducting plant trials. All
equipment items were evaluated to determine current performance relative to the original
design. The absence of key data for many equipment items and the variance in fluid
compositions from the original design , necessitated a pragmatic approach using sound
engineering judgement rather than definitive engineering design.
Traditional fully detailed de-bottlenecking calculations
were not appropriate. A high level hydraulic and thermal capacity estimate was made
to focus on key limiting equipment items.
Potential increases in plant capacity were identified via
minimum modifications and changes in operation.
Predicted gains were verified by further plant trials
following the completion of minor piping and control system modifications.

forecast increased market demand for specific refinery product streams. The
project objectives were to identify potential changes in operation and minimum
modifications to increase plant capacity.
IGL identified changes
in operation and minor control system modifications to the Hydrofiner plant to increase
product rates by 50%. The payback for the modifications was less than six months.
identified the two main bottlenecks of the Propane De-Asphalting Unit. Product rate
increases of 15% were achieved via changes in operation with no capital expenditure on
