Facility Siting Study: What a Chemical Process Engineer should know about?
During plant layout evaluation it is important to identify and consider all potential exposures that may affect the location of a new process unit and the impact that it will have around.
hashtagFacility siting study is related to process hazard analysis (PHA) and layout. In a few words, it is an assessment of occupied buildings given potential exposure to an explosion, fire and toxic hazards.
Depending on your process characteristics facility siting study reports may include evaluation to overpressure from vapor cloud explosions, fire radiation, toxic gas infiltration, or flammable gas infiltration.
Guidelines for Consequence Analysis of Chemical Releases (CCPS, 1999), provide information regarding how to evaluate the consequences from various hazards including explosions, flash fires, and toxic releases. Some of the common codes and guidelines referenced in siting studies include API RP 752 and API RP 753, NFPA 30, NFPA 58, NFPA 59A, 49 CFR 193, CSA Z276, EN 1493, API 2510, or IP 9.
Some commercial computer-based models software available are PHAST (DNV), SafeSite3G© (BakerRisk), CANARY (Quest Consultants). For sure there is much more to be said. I invite you to share your comments with us.
