The elimination of impurities from natural gas (water, CO2, H2S, mercaptans) is an obligation: in Europe, a max. of 20 mg/Sm3 in total sulfur (at 15°C and 1 atm) is allowed, as well as 2.5 vol% in CO2. It maximizes the calorific value of delivered g

Mixing efficiency of three Hartridge–Roughton mixers with different geometries is characterized by a segregation index measured via the Villermaux/Dushman test reaction and by Computational Fluid Dynamics. The small values of the segregation index

International audience; Process scale-up remains a considerable challenge for environmental applications of non-thermal plasmas. Undersanding the impact of reactor hydrodynamics in the performance of the process is a key step to overcome this challen

This article focuses on the role of interfaces on lysozyme inactivation and aggregation process in stirred reactor. The first order inactivation constant of this process has found to be proportional not only to the power imparted by the impeller but

Mechanisms of enzyme inactivation and aggregation are still poorly understood. In this work, we are considering the characterisation of both inactivation and aggregation in stirred tank reactor, with lysozyme as the model enzyme. The inactivation kin
