Economic and environmental implications of the development of UASB reactors in Mexico for sustainable industrial wastewater treatment

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The objective of this work is to demonstrate that the inclusion of an up‐flow anaerobic sludge bed (UASB reactor) within an industrial wastewater treatment plant reduces the plant's investment and operating costs compared to a system based solely on conventional complete‐mix activated sludge (CMAS), operating under the same design principles ...

Hydrogen donor‐assisted visbreaking of Canadian oil sands bitumen

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract High‐viscosity Canadian oil sands bitumen requires processing for efficient transportation and refining. Partial upgrading technologies, primarily based on thermal processing, can effectively reduce, or even eliminate, the use of costly diluent, increase bitumen quality and market value, potentially decrease greenhouse gas (GHG) emissions, and

Individual cylinder air–fuel ratio estimation and control for a large-bore gas fuel engine

International Journal of Distributed Sensor Networks, 2019
For internal combustion engines with multi-cylinders, the differences of fuel injection, air distribution, and even exhaust gas recirculation between cylinders may result in cylinder-to-cylinder imbalance, and then the exhaust emission and engine ...

Ligand Functionalization Regulation in Metal–Organic Frameworks for Waste PET Valorization Coupled With Energy‐Saving Hydrogen Production

EcoEnergy, EarlyView.
Amino‐functionalized Co‐BDC nanosheet arrays on nickel foam oxidize PET‐derived ethylene glycol with high efficiency. Electron‐donating NH2 groups optimize Co electron density, promoting selective C–C cleavage to formate (95.6% Faradaic efficiency) for conversion to potassium diformate.

Numerical Analysis and Optimization of a Continuous‐Flow pH‐TRC for Steady‐State Low‐Grade Waste Heat Recovery

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A steady‐state numerical model is established for a continuous‐flow pH‐TRC for low‐grade waste heat recovery. Based on carbonate and bicarbonate electrolytes, the influences of operating conditions and electrode structure on pH‐driven power generation are clarified.
