The Vaalkop water treatment works (WTW) abstracts water from the Vaalkop Dam, which is situated in the Crocodile West/Marico Water Management Area of South Africa. The bulk of the inflow into the dam is through a canal fed ...

The transport industry is one of the biggest contributors to air pollution, with the major air pollutants being COx, NOx, and SOx. SOx is produced by the combustion of the organic sulphur compound found in fuels, e.g. ...

The thermochemical conversion of waste tires for chemicals and power production is investigated using process synthesis techniques and experimental analysis. Pyrolysis and gasification technologies were evaluated in terms ...

Municipal wastewater pollution in developing countries is a great concern due to partially treated or untreated wastewater. Inflow and Infiltration (I/I) is a challenge in municipalities that receive stormwater as it impacts ...

The aim of this study was to determine the effects of the feedstock composition, such as biomass, polyethylene and their respective blend ratios, -gasifying agents and operating conditions on the product gas composition, ...

Power-to-chemicals processes hold tremendous potential to enable the widespread adoption of renewable sources of energy and to open many avenues to the green hydrogen economy. These processes will play a critical role ...

A 2D pseudo-homogeneous fixed bed reactor model was developed using ANSYS Fluent, based on an actual bench-scale Fischer-Tropsch reactor. The single-tube reactor had a diameter of 0.05m, which is representative of the ...

The industry’s great interest is to intensify the cobalt-based Fischer-Tropsch synthesis (FTS) process by increasing the per-pass conversion and the production of long chain hydrocarbons. To achieve this goal, it is ...

In this study, period four transition metal oxides (Zn, Cr, Mn, Co, Fe, Cu, Ni), acting as intermediate Lewis acids, were supported on activated carbon (AC) and used in the adsorptive desulfurization (ADS) of model and ...

The implications of comminution practices on the planning of a typical open pit mine was investigated in this study by means of computer simulation. The objective was to assess the effects of mining costs as well as ...
