Gas-to-liquids
Escravos GTL is due to start up in late 2013.
Syntroleum’s proprietary F-T process also uses
air rather than oxygen and the company was evaluating
a number of GTL projects but is currently concentrating
on biomass-to-liquids ventures.
A Japanese consortium has developed a pro cess
that allows natural gas containing CO2 to be used
directly as a feedstock rather than having to be
treated first. Japan GTL was suc cessfully trialled at a
500 b/d demonstration plant in Niigata bet ween
April 2009 and December 2011 by Inpex, Nippon
Oil & Energy, Japan Petroleum Exploration, Cosmo
Oil, Nippon Steel Engineering and Chiyoda in
cooper ation with Japan Oil, Gas and Metals National
Corporation (JOGMEC). Commercial opportunities
are now being sought.
oxygen plant and a GTL plant can be integrated on a
vessel. The capacity of the plant can be adjusted to
match the declining flow of associated gas throughout
the life of an oilfield, with plant modules
being shut down and removed for refurbishment
and/or re-deployed elsewhere.
A modular unit has been tested at the Petrobras
research site in Aracaju and it has been app roved
for commercial deployment.
Growing importance
By late 2013, GTL production will exceed 250,000
b/d. While this is still a small proportion of the
overall market for refined petroleum products, a
high oil price and premium over gas mean the
sector is set to grow in importance.
