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...

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...

Industrial transformers and circuit breakers operate with large voltage differences between current-carrying internal components and the grounded tank walls. A breakdown in the dielectric strength of the insulating oil in the tank due to contamination or other causes can lead to the formation of an...

Increasing the safety and security within the chemical supply chain has been a concern of the US government for several years. Both the Environmental Protection Agency (EPA) and the Department of Homeland Security (DHS) have active efforts to reduce societal risk of a toxic industrial chemical...

The Importance of SAFETY DESIGN On NEW Refinaries- portuguese

An Emergency Block Valves (EBV) is used as a means of isolating flammable or toxic substances in the event of a leak or fire. The installation, and use, of EBV's in many hydrocarbon services will significantly reduce the potential of fire and explosion damages caused by loss of hydrocarbon...

To perform LOPA's, fault tree analysis, SIL verifications and other quantitative likelihood analyses requires data. As much as everyone wants data, it always seems to be elusive or lacking in quality. This paper explores various issues that the authors have experienced when dealing with end user...

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...
