  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • Hydrogen production through chemical looping using NiO/NiAl2O4 as oxygen carrier

    A new autothermal route to produce hydrogen from natural gas via chemical looping technology was investigated. Nowadays, 90% of the worldwide produced hydrogen comes from fossil fuels, the most common process being Steam Methane Reforming (SMR), which produces several kg of CO2 equivalent per kg of hydrogen. In classic SMR technology, most of the greenhouse gases are vented to the atmosphere. ...

  • Graphical exergy analysis of reactive distillation column for biodiesel production

    This paper brings the novelty of the exergy analysis technique using Ex–N–A diagram to a packed reactive distillation (RD) column for biodiesel production. In this study, biodiesel is produced through the esterification of fatty acid with methanol. The simulation of the column was performed based on the non–equilibrium (NEQ) model of a three–phase packed RD system. The graphical Ex–N–A method was ...
