Preface The availability of various design tools and software made process engineering and design simple but also, in some cases, paradoxically led to inadequate design Unfortunately, not only young engineers but also reasonably experienced engineers are becoming more dependent on software tools without having a basic understanding of the design I have seen people using HYSYS® to estimate water boiling... failure on demand 347 ALARP model 348 Determination of SIL 348 Financial 350 Health and safety 351 Environment and asset 351 45423_C000.fm Page xviii Monday, August 27, 2007 11:16 AM xviii Process engineering and design using Visual Basic Programming .353 Program for pressure relief valve 353 Program limitations and notes ...
