Dear Members,
For a Process Engineer, what is the ideal way of carrying out hydraulics (line sizing, Control Valve sizing, Compressor circuit sizing, pump circuit sizing etc). What is the best and time efficient sequence of doing this? Please see below:
Line sizing referring to PFD
1. Start line sizing referring to PFD (without using any line lengths) to get an initial estimate of line sizes based on recommended pressure drop and velocity considerations. So, we will be ready with initial estimate of line sizes.
Next w.r.t. to P&IDs (considering total equivalent pipe lengths)
2. Do control valve sizing, pump circuit hydraulics, Compressor circuit hydraulics to finalize the line sizes.This will cover most of the piping in a unit.
3. Then for remaining lines (which do not come under above circuits), check and finalize the line size based on equivalent lengths.
Is the above an ideal way of carrying out hydraulics to fix line sizes.
Request your suggestions/comments on above.
As a Process Engineer, one have to carry out activities like Process Simulation, preparing H&MB, P&IDs, Equipment sizing, line sizing etc. My concern is to get a way to do the things in proper sequence so as to remove any rework etc. Since, the project schedules are very tight.
So, I have raised above question w.r.t. sequence of hydraulics only. Request members to focus on that only otherwise the discussion may lead to numerous directions without satisfying the response to question in principal
Regards,
PKS
