With the ensuing changes, the question must be asked, “Do Lang factors still present a realistic approximation of capital cost today?”http://www.hydrocarbonprocessing.com/Article/3475529/An-update-on-Lang-factors.htmlSat, 01 Aug 2015 00:00:00 GMTConsider Zone 0 vertical pumps for slop pitsOver the past several decades, a leading overseas HPI corporation experienced a disturbing number of explosions in its belowground hydrocarbon sump pits.http://www.hydrocarbonprocessing.com/Article/3475560/Consider-Zone-0-vertical-pumps-for-slop-pits.htmlSat, 01 Aug 2015 00:00:00 GMTConsultant: Managers need long-term focus to find downstream sustainabilityTop industry management should consider profits over the long term to make the business case for more sustainability, with a particular focus on results in the four-to-five-year range rather than on the initial year or two.http://www.hydrocarbonprocessing.com/Article/3475523/Consultant-Managers-need-long-term-focus-to-find-downstream-sustainability.htmlSat, 01 Aug 2015 00:00:00 GMTMust devices be certified for use in safety instrumented systems?For decades, process industries have used different forms of safety control based on what was available in the market. The simple answer to the question of whether SIS devices need to be certified is, "No," but operators and the industry as a whole continue to ask for certification anyway. Why is this? http://www.hydrocarbonprocessing.com/Article/3475537/Must-devices-be-certified-for-use-in-safety-instrumented-systems.htmlSat, 01 Aug 2015 00:00:00 GMTWetted surface area calculations for fire-relief sizing in ASME pressure vesselsAlthough individual operating facilities take many steps to protect plants from fire, pressure vessels within a fire zone must be protected by a pressure safety valve (PSV). Proper calculation of the vessel’s wetted surface area is a crucial step in properly sizing a PSV.http://www.hydrocarbonprocessing.com/Article/3475561/Wetted-surface-area-calculations-for-fire-relief-sizing-in-ASME-pressure-vessels.htmlSat, 01 Aug 2015 00:00:00 GMT
