[...]... understanding of the basic design This will improve the selfconfidence of the user The programs have been developed in Visual Basic to avoid limitations of other programming tools, e.g., Excel All programs have been developed to use both the International System of Units (SI) and English units (the xxi 45423_C000.fm Page xxii Monday, August 27, 2007 11:16 AM xxii Process engineering and design using Visual. .. 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 ... Datta, principal process engineer working with WorleyParsons, has twenty-seven years’ experience in the field of process engineering and design He holds a master’s degree in chemical engineering from the Indian Institute of Technology, Delhi, and has worked with several process consultancy organizations in both India and Australia Arun has been a consultant for a large number of process engineering organizations... organizations including refineries, oil and gas industries, fine chemicals, and pharmaceuticals His fields of expertise include heat and mass transfer, process simulations, exchanger design, pressure vessel design, design of safety systems, and design of control systems Some of his clients include BP Refinery, Caltex Refinery, Santos, ExxonMobil, ONGC, Indian Oil, Incitec, and Oil Search Arun is a chartered... also failed to recognize the limitations of Excel spreadsheets and develop something that does not produce the intended output In spite of different procedures and design tools, we sometimes come across some typical design requirements that are not covered by any known procedure Some understanding of basic mathematics and fundamental process engineering can solve a large number of problems without much... 11:16 AM xiv Process engineering and design using Visual Basic Pressure drop through the vane pack 218 General dimensions and setting of levels .219 The horizontal separator 219 Boot 221 Vertical separator .222 Separator internals 223 The inlet nozzle 223 The vortex breaker 224 Separator control .224 Pressure and flow... valve .264 Rupture disk .265 PRV installation and line sizing .265 Compressors and pumps 265 Fired heaters .266 Heat exchangers 267 Piping 267 Pressure vessels 267 45423_C000.fm Page xvi Monday, August 27, 2007 11:16 AM xvi Process engineering and design using Visual Basic PRV isolation valves 268 Inlet piping to PRVs... self-confidence is the key factor for inappropriate process design in many cases As everything in process design can’t be covered by software tools like HYSYS®, HTRI®, etc., most design/ consulting groups have developed their own design tools mostly using Excel® spreadsheets Excel spreadsheets are extremely easy to develop and easy to corrupt through cut -and- paste modifications as well as with attempts to... a and b are the lengths of the sides, h the height, and α the angle between the sides See Figure 1.1 Rhombus (equilateral parallelogram) Area = 1/2 ab (1.4) where a and b are lengths of diagonals Trapezoid (four sides, two parallel) Area = 1/2(a + b)h where the lengths of parallel sides are a and b and h = height (1.5) 45423_book.fm Page 4 Monday, August 27, 2007 12:44 PM 4 Process engineering and design . business Boca Raton London New York ARUN DATTA PROCESS ENGINEERING and DESIGN USING VISUAL BASIC ® 45423_C000.fm Page iii Monday, August 27, 2007 11:16 AM Visual Basic and Excel are registered trademarks. trademarks, and are used only for identification and explanation without intent to infringe.
