In this paper, a one-port time-domain/frequencydomain based technique using a short-circuited coaxial geometry inserted vertically in a liquid tank is designed and presented as a multi-level storage tank gauge and monitor. For storage tanks of small physical liquid levels, the attenuation inside the coaxial cable sensor may be neglected and both the physical liquid levels and liquid permittivit...

Cylindrical liquid storage tanks are considered as vital structures in industrial complex whose nonlinear dynamic behavior is of crucial importance. Some of these structures around the world have demonstrated poor seismic behavior over the last decades. There are several methods and techniques for rehabilitation and reducing damages in these structures which among them passive control devices, ...

The general context of this work concerns the latent heat storage (cold storage) by encapsulated spherical nodules of 7.7 cm in diameter containing a Phase Change Material (PCM) and filling a cylindrical tank (about 2500 nodules per m3). During the storage process, a cold heat transfer liquid flows through the tank to crystallize the PCM inside the nodules. The stored energy is released when a ...

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...

Background and aims: Process industries are known to be hazardous industries. Chemical Industrial process involves several processes such as drilling and production, storage, transportation, and refining. These activities are different in nature. Also, they are different in job Risks. One of the main and dangerous sections of the process is oil reservoir. Therefore, this study aimed to identify...
