Exergy and environmental analysis of black liquor upgraded gasification in an integrated kraft pulp and ammonia production plant

Daniel Alexander Florez Orrego, Meire Ellen Gorete Ribeiro Domingos

Some byproducts of the Kraft pulp mills, such as the black liquor (1.4 t/t ADpulp, 15% solids), still contain more than half of the exergy content of the total wood fed to the digester. This residue represents a key supply of renewable energy to the pulp a ...

Design and demonstration of a prototype 1.5 kWth hybrid solar/autothermal steam gasifier

Sophia Haussener, Iacopo Guscetti

A 1.5 kWth hybrid solar/autothermal steam gasifier was designed and tested for continuously producing synthesis gas. Time-averaged responses to a series of inlet flow conditions were examined in a high-flux solar simulator. The gasifier consisted of a SiC ...

Syngas Production with Thermo-Chemically Recuperated Gas Expansion Systems: An Exergy Analysis and Energy Integration Study

Daniel Alexander Florez Orrego

In spite of the large degree of energy integration in the modern syngas production units, the highly endothermic reactions of steam methane reforming and the combined steam and power generation still require a huge amount of energy that is typically suppli ...

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 ...

Catalytic supercritical water gasification: Interaction of sulfur with ZnO and the ruthenium catalyst

Christian Ludwig, Frédéric Vogel, Gaël Peng

Continuous catalytic supercritical water gasification (CSCWG; 400 degrees C, 28 MPa) of microalgal biomass (Chlorella vulgaris) was carried out at the microalgae production site of ZHAW in Wadenswil (Switzerland) non-stop over a period of 100 h. Characteri ...

Online Detection of Selenium and Its Retention in Reducing Gasification Atmosphere

Christian Ludwig, Andrea Testino, Mohamed Tarik, Adrian Hess

The emission of selenium from coal gasification processes can cause harm to the environment and downstream equipment. With upcoming legislation, reliable detection as well as control of such gas species become crucial. This study therefore addresses the de ...
