Biogas production from Opuntia stricta Haw.: microbial diversity and solid load influence on sludge recycle systems

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The search for alternative and sustainable energy sources becomes urgent as energy demand increases and fossil fuels become less available, especially in water‐scarce regions such as the Brazilian semi‐arid region, where current projections of global warming and the expansion of arid and semi‐arid zones point to a future of desertification ...

Influence of the single EGR valve usability on development of the charge directed to individual cylinders of an internal combustion engine

E3S Web of Conferences, 2017
Exhaust gas recirculation systems (EGR), aside to a catalytic converters, are nowadays widely used in piston internal combustion engines to reduce nitrogen oxides (NOx) in the exhaust gas.

A Method for Optical Quantification of Local Oxygen Limitations in Multiphase Bioreactors

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Spatial oxygen limitation is a major source of physiological stress and metabolic, scale‐dependent heterogeneity in aerobic bioprocesses. In gas‐liquid stirred tank reactors, oxygen availability is governed by hydrodynamics and mass transfer and is therefore inherently non‐uniform.

A General Workflow for Tangential Flow Filtration Perfusion Scale‐Up

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Tangential flow filtration (TFF) perfusion using hollow‐fiber modules offers substantial advantages over other mammalian cell retention technologies. Recently, increased awareness of Starling flow has helped to enhance filtration performance to similar, or even higher levels compared to alternative technologies.

Selective exhaust gas recirculation in combined cycle gas turbine power plants with post-combustion carbon capture [PDF]

, 2017
Selective Exhaust Gas Recirculation (S-EGR) consists of selectively transferring CO₂ from the exhaust gas stream of a gas-fired power plant into the air stream entering the gas turbine compressor.

Methanol With Increased Water Content in Internal Combustion Engines

Chemie Ingenieur Technik, EarlyView.
This study investigates the potential to improve overall Well‐to‐Wheel efficiency by using low‐purity methanol from synthesis of hydrogen and furnace gas as CO2‐source. Combustion efficiency is comparable to pure methanol, while distillation energy could be saved.
