Process Safety Technical Areas

The LNG industry, if not the entire energy industry, may be at a crossroad. Expectation of large shale gas supplies in the United States, with a backdrop of international economies in precarious states, makes more uncertain the promise of major investments in LNG import facilities. Already, a...

The Importance of SAFETY DESIGN On NEW Refinaries- portuguese

While Safety Instrumented Systems (SIS) can be an essential element of process facility design to minimize the potential for process incidents, in some cases they can also be over-applied in the design phases of capital projects where the Safety Instrumented Functions (SIFs) associated with the SIS...

In order to comply with regulation requirements, a refinery needs to perform major revamps to produce different grades of Diesel, namely ULSD, Off-road Grade and Regular Diesel. The existing tankage allocation needs to be changed to accommodate the hydrotreater feed components and the new products...

The advanced software (FAHTS) and (USFOS) enhances the capabilities of risk evaluations and fire simulations regarding survivability of offshore drilling structures. Coupling industry leading 3D Computerized Fluid Dynamic (CFD) software packages with Finite Element Analysis (FEA), permits the...

The formation of a flammable vapor cloud following a spill of cryogenic liquids, such as ammonia and LNG (liquefied natural gas), on a ground or water includes significant toxic, fire or explosion hazards. The ability to predict the consequences of such an event is crucial to perform proper risk...

Layer of Protection Analysis (LOPA) continues to be more and more widely utilized in the Petrochemical and other industries. LOPA is a “simplified” tool, which is true relative to tools such as Quantitative Risk Assessment and Fault Tree Analysis. However, simplified does not mean simple on an...

The discussion of societal risk criteria for the process industry began in the 1970's, led primarily by the Dutch and British governments. Most of the discussion, however, has centered on fixed facilities. The literature on the societal risk of hazardous goods transportation, particularly by...

Learning from experience is one of the four pillars of Risk-Based Process Safety. Incidents that occur at one facility often provide opportunities to strengthen management systems at other facilities. Sharing the technical lessons learned from incidents is morally right and vital to improving...
