Sirous Peikar said the project
is expected to come online in the second half of the next Iranian calendar year
which begins on March 21.
He said the facility is 60%
complete in engineering, 49.5% in item procurement and 32.1% in construction
Nowadays, gas condensates
sweetening is used solely to prepare them for transportation. Requirements for
mercaptan removal from gas condensate are applied only to light most corrosive
methyl and ethyl mercaptan, total content must not exceed 0.004% wt.
Gas condensates are sweetened
from light (C1-C2) mercaptans by extraction with alkaline solutions and
subsequent regeneration of alkali in the presence of phthalocyanine catalyst
and oxygen. The resulting disulfides are not separated from gas condensate. Thus,
concentration of sulfur compounds in gas condensate remains unchanged.
