Effect of cell retention techniques in Komagataella phaffii lab‐scale continuous processes
Biotechnology Progress, EarlyView.Abstract Perfusion technologies play a growing role in the implementation of continuous processes for biotherapeutics production in mammalian‐based manufacturing. However, their application to alternative production hosts is limited. Cell retention systems are of key importance for the efficiency of perfusion bioreactors.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract NOx emissions from gas boilers severely impact the environment, and flue gas recirculation (FGR) technology can effectively reduce such emissions, yet the effects of different FGR rates on combustion performance and NOx formation remain unclear. This study thus used numerical simulation (via ANSYS Fluent, adopting the realizable k‐ε turbulence

Exhaust Gas Recirculation System
, 2015 It is today undoubted that humans have to reduce their impacton the environment. Internal combustion engines, being the major power source in the transportation sector as well as inindividual transport, play an important role in the man-made emissions. While the mobility in the world is growing, it is important to reduce the emissions that result from ...

Making gas-CCS a commercial reality: The challenges of scaling up [PDF]
, 2017 Significant reductions in CO2 emissions are required to limit the global temperature rise to 2°C. Carbon capture and storage (CCS) is a key enabling technology that can be applied to power generation and industrial processes to lower their carbon ...

Mass Exchange Flow Process in Side Channel Pumps: Effects of Different Geometrical Parameters
Energy Science &Engineering, EarlyView.Figure 1 shows the Mass Flow Exchange (MFE) in the impeller at z = 7.5 × 10−3 m at 1.0 Q/QBEP, operating point for impeller scheme 1 (IMP 1), and impeller scheme 2 (IMP 2). The flow begins to exit the impeller at the outer radius and enters at the inner and central radii. IMP 1 exhibits more flow in and out compared to IMP 2. ABSTRACT The functionality

Energy Science &Engineering, EarlyView.Integration of a steam cycle with an existing gas turbine increased efficiency from 32% to 51%, reducing fuel consumption by 21.4% and CO2 emissions by 18.6%. The modification generated USD 13.9 million annual savings and lowered the Levelized Cost of Energy to 38.7 USD/MWh, with a 3‐year payback.
