Scientists at the Research Institute of Petroleum Industry in cooperation with the National Iranian Gas Company have indigenized solvents used in gas-sweetening units of refineries.
Stressing that Iran has the world’s second largest natural gas reserves, Ali Zoghi, who leads the project, said Tuesday, “To exploit such resources, treatment is necessary. That’s why gas-sweeting units are among the most important parts of natural-gas refineries. The technology covers the formulation of gas-sweetening solvents (Parsisol Solvent), the design of the gas-treating unit based on Parsisol Solvent, the management of solvents, and the recycle of used solvents.”
Among other things, high absorption of acid gases, little corrosion, the possibility of using common alloys in the process, elimination of anti-corrosion material, production of little foam, high heat-retention, and low energy consumption are some of the advantages of Parsisol Solvents.
The results of a field test on an industrial scale in Masjed Soleyman Refinery show that the Iranian product outperforms a Canadian solvent previously used in the refinery, he concluded.
