*Contract License and Basic Engineering of the First Large-scale Plant
for Production of DME*
Lyngby, June 16 2004
Petrochemical Research & Technology Company (NPC-RT) of Iran and Haldor
Topsoe A/S of Denmark have been, under a collaboration agreement signed
two years ago, engaged in a joint effort to demonstrate new technologies
for the petrochemical industry. It is with a great pleasure to announce
that this collaboration has now resulted in a contract with Zagros
Petrochemical Company to license technology, provide engineering and
supply catalyst for a dimethyl ether (DME) plant.
The plant which is to be constructed at Bandar Assaluyeh, Iran with a
capacity of 800,000 MTPY of DME, is based on technology and catalyst
developed by Haldor Topsoe A/S for dehydration of methanol and made
available in Iran by joint scientific and technical collaboration with
NPC-RT.
The implementation of this project will result in a world-wide increase
in DME production of more than 200% and represents a breakthrough for
the application of DME as a green fuel.
For further information on the project, please contact Haldor Topsoe A/S
at: jep at topsoe.dk <mailto:jep at topsoe.dk> and NPC-RT at: info at npc-rt.ir

International DME Association homepage: www.aboutdme.org

On the subject of conversion and densification I would like to note the
recent
development of a catalyst by Haldor Topsoe which converts syngas (H/CO) to
DME (dimethyl ether). It uses a slurry bubble column to convert syngas to
methanol to DME in a single pass with efficiencies approaching 90%.
This is at the commercialization stage in Japan and they already have
demonstration vehicles in service. DME is very similar to LPG and a lot
of research is currently focused on it's use as a Diesel substitute because
of it's cetane rating of 55. A standard dual fuel propane conversion
kit will
get you on the road without the development time. I think a portable wood
chip gasifier and DME production system at the biomass source is one
solution for site conversion to a portable fuel.
