According to the Petroleum Industry Research Institute,
Hamid Ganji, director of the group's technologies for recovery and conversion
of gaseous pollutants, said in sulfur recovery or sulfur recovery processes hydrogen
sulfide is converted and in the sweetening process, hydrogen sulfide is
separated from the existing compounds using an amine solvent.
Referring to the dangers of hydrogen sulfide to the
environment, he added: "Under such conditions, strict environmental laws
are applied to prevent its release. Acid gas produced by refineries is
essentially converted into elemental sulfur in sulfur recycling processes, from
which sulfur can be used in chemical, agricultural and health industries. Doing
so not only eliminates environmental pollution but also has economic value.”
The director of the Department of Recovery Technologies and
Conversion of Gas Pollutants of the Petroleum Industry Research Institute,
emphasizing that the Petroleum Industry Research Institute has been working in
the field of sulfur recycling technology for more than 10 years, said: “These
units were owned by foreign companies, which due to the importance of
environmental issues, the Petroleum Industry Research Institute localized the
technical savvy of the SRU process in its plans.”
He also pointed to the importance of localization of this
process by the Petroleum Industry Research Institute, and said: "The
research institute has not only been able to gain technical knowledge of SRU
process, but also made catalysts related to this process well and technical
knowledge of making these catalysts with the aim of commercialization."
