In this paper, the annual and economic performance of an integrated solar combined cycle (ISCC) with indirect energy storage tanks is investigated. The study includes four scenarios, in which the combined cycle performance was studied exclusively in the first scenario. In the second scenario, the integrated solar combined cycle (ISCC) was examined, and the use of supplementary firing instead of...

The distribution of daily requirement of water in multi-storeyed semi-urban residential buildings in India involves pumping from the ground level to a reservoir at the top, and gravity feed to all levels below. String diagrams bring out the scope for reduction of unnecessary movement of water. A modified storage arrangement is proposed resulting in a small saving in energy required for water di...

This paper describes the application of the ACFM technique for weld inspection and focuses on recent experience in both Europe and Central America in the use of the technique for the inspection of steel storage tanks. Inspection of the tank floor is usually conducted using magnetic flux leakage methods but it is recognised that this cannot be applied to the detection of cracking in the welds jo...

Advantages, such as thermal storage improvement, are found when using PCMs (Phase Change Materials) in storage tanks. The inclusion of three different types of materials in a 60 l test tank is studied. Two test methodologies were developed, and four tests were performed following each methodology. A thermal analysis is performed to check the thermal properties of each PCM. The distributions of ...

Cylindrical steel tanks are important components of many industrial plants such as oil refineries and chemical plants. Usually failure of cylindrical tanks leads to serious consequences. During the past earthquakes such as 1964 Alaska and 1999 Turkey seismic performance of cylindrical tanks revealed that tanks are seismically vulnerable. Therefore, evaluation of seismic performance of these str...

This work addresses the large-scale crude oil scheduling problem of China’s SINOPEC Maoming refinery importing various types of crude oil from two terminals via long-distance pipelines. A hierarchical decomposition approach is employed to construct a two-stage MILP model of the practical refinery operations. In the upper level model, storage and charging tanks are aggregated to determine the in...

The grape juice industry has shifted almost entirely from the old method of storing juice in 5-gallon carboys to cool storage in tanks at 22 to 28 F (-5.5 to -2.2 C). Excess tartrates are precipitated during storage. When juice was stored in carboys, the carboys wNere filled at processing temperature, and either spray-cooled or allowed to cool slowly at the cellar storage temperature. For the m...

Research Objective — This project focuses on the development of reliable theoretical and efficient computational descriptions of the chemistry of high-level waste simulants in highly concentrated solution and the experimental validation of this approach. It is an extension of previous work which: a) Determined the mechanism of H2 formation in waste simulants allowing quantitative prediction of ...

A methodology for simulating the dynamics of large industrial fires in the outdoor environment is presented. The large eddy simulation techniques developed by the authors and their collaborators are used to simulate a fire on top of a large oil storage tank adjacent to several neighboring tanks. The governing equations are modified to account for the stratification of the ambient atmosphere. A ...
