MILAN, Italy -- Increasing demand for hydrogen in refineries
and its high production cost are making it imperative for
refiners to profitably re-use many hydrogen-rich streams,
executives with Indian Oil said on Wednesday.
Speaking at the IRPC 2012 conference, Debangsu Ray said that
an out-of-the-box approach is key to avoiding the need for
expensive purification technologies.
A major part of the
benefit can be achieved by simple piping changes, Ray
Indian Oil says it is currently saving $15 million per year
at its Panimat refinery from this exercise.
Low-purity hydrogen from process units can effectively
supplement the incremental hydrogen requirement, Ray
Hydrogen management is all about recovering and
re-using low-purity hydrogen, which otherwise would have been
wasted without major investment.
However, a critical review of all of the affected processes
and an understanding of the tradeoffs are essential to
effectively implementing the process, he noted.
For example, careful consideration must be given to have
minimum impact on hydroprocessing objectives.
Indian Oil approaches the problem by identifying sources of
hydrogen-rich streams in terms of both quality and quantity,
while also looking for sinks.
From there, the company customizes its intake of impure
hydrogen, as per the requirement of its consumer units.
In the end, the re-used hydrogen is a critical component of
upgrading facilities used to process heavier
crudes, which are increasingly prevalent in todays
