Screening of chemical pulp, revisiting technology options, and the state‐of‐the‐art equipment—A critical review

The Canadian Journal of Chemical Engineering, Volume 101, Issue 10, Page 5643-5655, October 2023., 2023
Abstract Screening of pulp can be expressed as a process where solid contaminants are removed from a pulp slurry without an excessive loss of fibres of acceptable quality. The impurities originate from the feedstock, or they are generated during the transport, handling, storage, or pulping process.

Computational Fluid Dynamics Simulation Assessment of Inlet Configuration Influence on Enhancing Swirl Flow Microbubble Generator Performance

Journal of Engineering, Volume 2023, Issue 1, 2023., 2023
In this study, a CFD simulation analysis was used to predict the characteristics of a swirl flow as a reference to optimize a new design of microbubble generator. To examine the impact of the inlet design, three different configurations of the inlet type were applied, namely single inlet, double inlet, and tangent‐circle inlet.

Study on the Solution of Sand Slabbing in the Tailing Sand Bin of Huanggang Iron Ore Mine

Advances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022
In order to improve the tailings utilization rate and realize full tailings’ filling in Huanggang iron mine in Inner Mongolia, a flocculation settlement system was added, which resulted in silting and consolidation of tailings in sand silts. Based on this, the reason for the deposition and caking of tailings was obtained through analysis, and a set of ...

Upgradation of Iron Ore Fines and Slime by Selective Flocculation Using Surface‐Active Agents, Settling Study, and Characterization of the Beneficiation Waste for Value Addition

Journal of Chemistry, Volume 2022, Issue 1, 2022., 2022
Washing of iron ore fines and slime (10% and 25% w/v, slurry concentrations) with two types of surface‐active agents (sodium humate (synthesized) and AD 200 (commercial)) at varying concentrations at pH 8 was conducted for ascertaining the efficacy of dispersants in beneficiating the low‐grade iron ores. The beneficiation process follows the “selective

Simulation of Separation of Salt Solution from Crude Oil in a Hydrocyclone

Journal of Engineering, Volume 2022, Issue 1, 2022., 2022
In this study, separating water from oil is studied numerically. In this simulation, the Reynolds Stress Model and the mixture multiphase model are used for coupling the velocity and pressure equations using the SIMPLE algorithm. The simulated geometry is taken from an experimental setup.

Photocatalytic membrane filtration and its advantages over conventional approaches in the treatment of oily wastewater: A review

Asia-Pacific Journal of Chemical Engineering, Volume 15, Issue 5, September/October 2020., 2020
ABSTRACT Clean water supply has become one of the biggest challenges of the 21st century; therefore, water source protection is of increasing importance. Beyond environmental protection reasons, economic concerns—derived from increasing costs of processing water and wastewater discharge—also prompt industries to use advanced wastewater treatment ...

Adaptive Hybrid Soft‐Sensor Model of Grinding Process Based on Regularized Extreme Learning Machine and Least Squares Support Vector Machine Optimized by Golden Sine Harris Hawk Optimization Algorithm

Complexity, Volume 2020, Issue 1, 2020., 2020
Soft‐sensor technology plays a vital role in tracking and monitoring the key production indicators of the grinding and classifying process. Least squares support vector machine (LSSVM), as a soft‐sensor model with strong generalization ability, can be used to predict key production indicators in complex grinding processes.
