The filter plays a vital role in protecting Pump 15011-P and controlling iron levels in Unit 110.
According to the company’s public relations office, the filter was jointly developed by Arvand’s Maintenance and Technical Services Department and Petro Pooshesh Alborz Company over a four-month period. The domestically built unit has now fully replaced the imported model, preventing foreign currency outflow, improving production stability, and significantly reducing operational costs.
The 15003-FT filter prevents solid particles from entering Pump 15011-P. Under normal operating conditions, it is fed by Vessel 15009-V. When the filter is out of service, the system is forced into bypass mode, which can raise iron levels in Unit 110’s reactor and disrupt the SOW system — a risk that may lead to production interruptions and negatively impact EDC unit performance.
In response to this challenge, Arvand’s specialists leveraged internal technical expertise and collaborated closely with Petro Pooshesh Alborz to design and manufacture a domestic replacement. The initial prototype was produced within 60 working days and included several engineering upgrades over the imported version. The final production model was then fabricated using PTFE instead of PFA, providing significantly enhanced chemical resistance and extending equipment lifespan under operational conditions.
The cost of local manufacturing is substantially lower than that of the imported filter, and the domestic solution eliminates long production stoppages previously caused by extended foreign procurement lead times.
