2026 P-13 Bulk Oil Storage Facility Complete Practice Test

Vapor recovery in cone roof storage is all about capturing vapors that form as liquids are heated or displaced and returning them to the storage system. By pulling the vapors back instead of venting them, you reduce emissions of volatile organic compounds and reclaim product that would otherwise be lost. Venting to atmosphere would release pollutants and waste product, which is why that option isn’t the primary purpose. While monitoring vapor pressure is part of tank management, it isn’t the main job of the recovery system, and cooling the product isn’t accomplished by vapor recovery.
