hi
i need a procedure for SIL & HAZOP study in gas refinery such as definition of nodes, deviation, safe guard and recommendation.
thanks
perhaps
“A Guide to Hazard and Operability Studies”, first edition, 1977, published by Chemical Industry Safety and Health Council of the Chemical Industries Association"
will help?
Following
As a first step, refer to the relevant international standards:
IEC 61882 Hazard and operability studies (HAZOP studies) - Application guide
IEC 61511 Functional safety - Safety instrumented systems for the process industry sector
i want to calculate finite speed thermodynamic analysis with EES or MATLAB
