The Co unit production capacity is 140 kt/y of Carbon Monoxide,the feed of
which is natural gas received from the National Iranian Gas Company at the rate
of 87927 T/Y.
The feed is mixed with steam after desulphurization and flow through the pre
reformer at which higher hydrocarbons are broken to methane,CO,CO2 and Hydrogen
and then passes through the reformer where sysngas is formed from the
endothermic reaction of methane with steam .The reformer outlet steam is cooled
to condensate and separate water ,then its CO2 content is separated by amine
solution and returned to the reformer and discharged H2&CO are separated in
a cold box to produce pure carbon monoxide product.
The project cost was 37 million USD for the grant of license ,BEP,EP and
technical services during construction and erection. The total project cost was
346 billion Rial at the time of project execution .
License was granted by Haldor Topsoe from Denmark and EP carried out jointly
