Aim. Accidents at oil and gas facilities are among the main causes of environmental pollution loss life. In interests solving problem ensuring safety facilities, a review state in republic Yemen was carried out, statistical data on accidents were analysed, defined events that cause fire hazardous situations build scenarios for occurrence development fires through study an accident Aden refinery...

The purpose of this research was to introduce and describe a model for Fire Quantitative Risk Assessment of in petroleum Storage Tanks. A novel model was designed to determine the risk of a fire occurrence using of Loss Causation and Swiss cheese models. Then, based on FTA, model and its integration with our initial proposed model, the final model was obtained for fire hazard determination in h...

With all the real waste lying about, it might seem strange for chemists to create artificial waste. But that's exactly what's being done as part of the effort to ameliorate the seemingly intractable problem of radioactive contamination at Hanford Nuclear Site in southeastern Washington State. Cleaning up 55 million gallons of radioactive waste stored in tanks is a key task at the Hanford site, ...

In a molten-salt solar power tower, liquid salt at 290oC (554oF) is pumped from a ‘cold’ storage tank through the receiver where it is heated to 565oC (1,049oF) and then on to a ‘hot’ tank for storage. When power is needed from the plant, hot salt is pumped to a steam generating system that produces superheated steam for a conventional Rankinecycle turbine/generator system. From the steam gener...

Thermal performance of a solar water heater mainly depends on the thermal stratification. Thermal stratification in solar water tanks is essential for a better performance of energy storage systems where these tanks are integrated. In this research work, the performance of a solar water heater with a mantle heat exchanger is investigated experimentally. The heat exchanger is assessed for a rang...
