Multi-time integration approach for combined pulp and ammonia production and seasonal CO2 management

François Maréchal, Daniel Alexander Florez Orrego, Meire Ellen Gorete Ribeiro Domingos

In this work, the gasification of the black liquor is proposed as an alternative ammonia production route. Due to the seasonal variation of the energy prices, a multi-time integration approach that combines different technologies and energy inputs is used ...

The impact of sorbent geometry on the sulphur adsorption under supercritical water conditions: a numerical study

Christian Ludwig, Andrea Testino

A numerical model to show the impact of the adsorption bed geometry on the desulfurization process of wet biomass under supercritical water (SCW) gasification process has been developed. Three different geometries, straight channels (pipe), sharp-edged cha ...
