Integration of Bio-refinery Concepts in Oil Refineries

open access: yes, 2017
In this work, the systematic integration of bio-refineries within oil refineries is considered. This is particularly relevant due to the lack of adaptation of existing refineries to diminishing oil supply. Moreover, the integration of oil and bio-refineries has a massively positive effect on the reduction of CO2 emissions.

Thermogravimetric monitoring of oil refinery sludge [PDF]

open access: yesJournal of Analytical and Applied Pyrolysis, 2014
The present work has two dimensions: analytical and environmental. On the one hand we proved that thermogravimetric analysis can be used to perform fast characterization of oil refinery sludge. To this end, thermogravimetric curves were deconvoluted by using autocatalytic kinetics to take into account acceleratory phases in a thermal degradation ...
