Biolubricants are promising substitutes to
mineral oils or petroleum-based lubricants in many
industrial applications. In the present study, a techno-
economic analysis is carried out for evaluating the
production of Ethylene glycol dioleoyl (EGD)
biolubricant produced from waste cooking oil (WCO)
and from biodiesel directly. Two scenarios of the process
were studied. Scenario I was that the production process
is comprised of two parts: (1) biodiesel production from
WCO; (2) biolubricant production from biodiesel, while
scenario II was only the second part (biolubricant
production from biodiesel).The economic assessment for
the process in Egypt (for both scenarios) was performed
based on the results of process simulations and design
calculations.In
addition, it was found that the biolubricant could be sold
with a very challenging prices and the process would still
be economically feasible and profitable. Despite, both
scenarios are promising, scenario I showed a much lower
cost of manufacturing, selling price and thus, break-even
time. The main reason of this result is that big biodiesel
price compared to WCO price.
