“…Therefore, the change of the output of flowmeter and the change of the output of pressure sensor are all complex, and each signal appears as a complex superimposed signal, which is an irregular signal. The essence of EMD is to decompose an irregular frequency wave into multiple residual waves with single frequency [11] . Since most of the data to be analyzed does not always conform to intrinsic mode function, and the data may contain multiple fluctuation patterns at time [12] .…”

Extra uncertainty is introduced to the result of flowmeter calibration by flow fluctuations in the flow standard facility. Identifying sources of fluctuations is important for the location and elimination of the fluctuation sources in the flow standard facility, however it is difficult to diagnose the direction of fluctuation source when multiple sources exist. A correlation analysis method based on Empirical Mode Decomposition (EMD) utilizing the signals of pressure sensor and flowmeter is proposed to diagnose the directions of different fluctuation sources. The proposed method could separate the superposition signal of multiple fluctuation sources and effectively diagnose the directions of multiple fluctuation sources at one time and provide accurate information for the location and elimination of the fluctuation sources. Experiment platform was built based on a water flow standard facility and the direction diagnosis experiment of double fluctuation sources was conducted to verify the effectiveness of the proposed method. The experiment results shows that the directions of multiple fluctuation sources could be accurately diagnosed by the proposed method.

“…RTD is a probability distribution model that predicts how long a fluid element stays in a reactor. It aids in reactor troubleshooting and describes the flow and mixing within reactors [101,102]. RTD is vital in evaluating the design of the continuous operating chemical process system and optimizing its working parameters.…”

“…The concept of radiotracers in troubleshooting investigation and process optimization in numerous industries has attracted technologists and scientists because they allow small quantities of a radioisotope to be precisely evaluated [98]. They offer many benefits, including the best detection sensitivity and the ability to offer real-time measurements [101,102]. The RTD is a frequently used concept for characterizing flow in chemical reactors and determining the MRT of process fluid [104].…”

The extraction of useful minerals or geological materials from the Earth’s crust, most typically from various sources, is crucial to a country’s development and progress. Mineral-rich countries use these resources to transform their economies and propel them toward long-term prosperity. There is an urgent need for the world to increase mineral exploration efforts, improve the recycling of important metal-containing resources, and extract them using upgraded hydrometallurgical procedures with high recovery efficiency. This review paper highlights the importance of strategic and critical metals in the economy and the role of nuclear techniques in the analysis, process optimization, and remediation of metals using solvent extraction, adsorption, and chromatographic resins. Radiotracer analysis, X-Ray Fluorescence spectrometry (XRF), Neutron Activation Analysis (NAA), and X-Ray Diffraction (XRD) are appropriate for improving laboratory-based hydrometallurgical processes, with future technical and economic benefits. The development and installation of novel instruments to provide the real-time control of mining and mineral processing plants for improved control have the potential to aid in the recovery of a broad range of metals.
