4. Holding the probe away from the compo nent interface. The probe must be placed at the proper interface of the component being analyzed. Placing the probe even 1 centimeter from the interface can result in a false reading, indicat ing that the component is not leaking, when in fact it is leaking.

Ammonia Refrigeration

Ammonia is considered a high health hazard because it is corrosive to the skin, eyes, and lungs. Exposure to 300 parts per million (ppm) is immediately dangerous to life and health. Ammonia is also flammable at concentrations of approximately 15% to 28% by volume in air. When mixed with lubricating oils, its flammable concentration range is ...

Process safety management (PSM) ... The management of FPG has since announced that the duty supervisor could have shut down the process in the case of a leak. However, because the potential shutdown losses of ARO-3 are extremely high, with an annual output value of US$2.3 billion, the decision of whether to shut down the …

CEP: Process Safety Beacon

Meeting the Needs of the Water-Energy Nexus. Water is required to produce energy, and energy is required to make use of water — the two are, and always will be, inextricably linked. Engineers must understand the water-energy nexus in order to manage both efficiently and sustainably.

Identifying barriers to a process safety culture

A process safety lagging indicator used in the energy industry is hydrocarbon leak quantification, which measures leak quantity, incident severity, cause and consequence. It considers criteria that would make the incident more severe and adds these up in a weighted fashion to get a severity score for that incident.

Deep Neural Networks for Source Tracking of Chemical

In order to train and validate neural networks, sensor detection database for various leak accident scenarios is needed. However, safety and cost problems are too huge to conduct experiments on various leak accident scenarios for real chemical plants. For this reason, CFD simulations for a real chemical plant geometry were conducted to …
