According to Arvand Petrochemical’s Public Relations Office, the in-house manufacturing of model 42E-15010 graphite plate heat exchanger was completed in collaboration with a knowledge-based Iranian company, under the supervision of Arvand’s engineering department. The first unit, after passing comprehensive performance and pressure tests, has now been installed and commissioned in the production line.
This specialized exchanger plays a crucial role in cooling 10% hydrochloric acid during the vinyl chloride monomer (VCM) purification process. Following international sanctions and the withdrawal of Germany’s SGL Technik GmbH from supplying the equipment, Arvand Petrochemical localized the technology using domestic expertise and applied technical know-how.
The project involved identifying and sourcing materials such as graphite, specialized resins, and custom compounds, which were tested under operational conditions using hydrochloric acid and various solvents. The innovation lies in reinforcing the exchanger plates with carbon fiber to enhance mechanical strength and reduce fragility—a common issue in imported models.
Another breakthrough was the redesign of the gaskets, using a nano-graphite and resin blend, which improved sealing performance, reduced leakage risks, cut production costs, and simplified maintenance.
After full assembly, the unit underwent rigorous pressure and leak tests, with flawless performance confirmed.
This achievement demonstrates Iran’s growing capacity for industrial self-sufficiency and highlights the country’s ability to reduce reliance on foreign suppliers while opening new horizons for localizing strategic technologies.
