Inserting an Additional Vortex Finder to Improve the Performance of Cyclones in Series

Separations, Journal Year: 2025, Volume and Issue: 12(3), P. 60 - 60

Published: March 3, 2025

Multiple cyclones working in series are sufficient for heavy separation tasks at the cost of significant energy consumption. The majority researchers conducting optimization studies on multiple have attempted to find best possible compromise between pressure drop and collection efficiency by optimizing geometry cyclones. In a departure from this approach, we report novel design. Using proposed method, exit gas is divided into dirty clean inserting secondary vortex finder (SVF) primary (PVF) previous cyclone. flows succeeding cyclone, whereas passes over cyclone directly device farther behind. Methodologically, performance was tested experimentally, computational fluid dynamics (CFD) simulations were employed. Reynolds Stress Model (RSM) turbulence Discrete Phase (DPM) used simulate turbulent two-phase flow within gas–solid separator, capturing three-dimensional, transient, characteristics flow. Our test results showed that new configuration clearly reduces consumption while not hindering overall efficiency. CFD simulation optimize SVF’s diameter length. indicated having an SVF with optimal dimensions significantly enhances space thus improves addition, equation established describes volume flowing

Comparative Techno-Economic Analysis of Negative Emission Co2 Power Plant vs Ccgt with Ccs

Published: Jan. 1, 2025

A techno-economic analysis is performed on the negative CO2 emission gas power plant (nCO2PP) vs combined cycle turbine (CCGT) with carbon capture and storage (CCS). In nCO2PP it can be distinguished following three islands: fuel preparation, generation separation capture, respectively. The CCGT CCS are modeled in commercial software. amine has been used as reference to represent state-of-the-art technology. Both CAPEX OPEX well incomes from sewage sludge disposal avoided emissions have included analyses. boundary of cost analyses includes plants, processes conditioning. results show that levelized electricity (LCOE) using exhaust gasifier comparable capture. Due high electrical energy consumption equipment cost, LCOE much higher when plasma used. strongly depends income emissions. Further reductions expected for development technology maturity.
