Welcome to this presentation
It will show you, on a practical case, how the process design of a typical Oil & Gas facility, an Oil & Gas production (Upstream) facility is done
Process design bases identification
Process scheme selection
Process simulations
Sizing of Process Equipment
Specification of Mechanical Equipment
Comments are most welcome ([email protected]), which I will incorporate for the benefit of all.

Process Design case study
Some equipment are designed and some other are specified by Process. Remember which ones?
Equipment performing a process function, e.g., separation, are
designed by Process.
Equipment performing a mechanical function, e.g., pumps, compressors as well as heat exchangers, are specified
by Process.
