新方法降服“油老虎”

Core Viewpoint - The company successfully addressed a significant operational challenge, referred to as the "oil tiger," by implementing innovative solutions that improved wastewater management and enhanced product quality [1][2]. Group 1: Operational Challenges - The "oil tiger" posed a serious issue during the cold coke discharge phase, leading to the generation of large amounts of wastewater and severe oil-water emulsification, which traditional methods could not effectively manage [1]. - The company faced difficulties in maintaining coke quality due to the persistent presence of oil in the coke pool, necessitating manual oil removal [1]. Group 2: Innovative Solutions - The team developed a new approach by adding a diesel washing line to the gas phase of the discharge tower, using diesel as an extraction agent to remove oil from emulsified water [1]. - The precise injection of diesel was critical, requiring careful calibration to avoid waste while ensuring effective oil removal [1]. Group 3: Team Collaboration and Results - The team combined the experience of senior employees with the analytical skills of younger staff to refine their methods, transforming a traditional approach into a more precise and effective process [2]. - As a result of these efforts, the wastewater quality improved significantly, with the chemical oxygen demand (COD) stabilizing and monthly wastewater discharge volumes decreasing substantially [2].
