[Thick Smoke Observed Above Tehran Refinery on Sunday; Officials Say It Was Due to Power and Technical Failure] Golden Finance reported on November 8th, citing Iran's Tasnim News Agency, that thick smoke appeared above the flare system at a Tehran oil refinery on Sunday morning. The refinery's public relations department subsequently stated that due to a power and technical failure, the flare system was activated to comply with safety operating procedures and ensure stable production. The smoke was caused by this safety procedure and emergency gas venting; no fires occurred in any of the refinery's production units. Currently, the situation is under the control of the operations team, and related production processes are gradually returning to normal. Fuel production continues unaffected. Activating the flare system under such circumstances is a normal operation and part of the standard safety mechanisms in the oil refining industry.
