Advanced solution for efficient oil removal from heating medium water in oil processing enterprises
Advanced oil removal technology for heating medium water
Due to the leakage of heat exchangers in refining units, low-temperature heat cycle water (heating medium water) of oil processing enterprises always contains a certain amount of oil matter. Oil that disperses in the water will mix with other suspended matter and is more likely to deposit on the walls of heat exchangers, forming grease dirt that is difficult to clean.
This grease deposition seriously influences the heat exchange efficiency of heat exchangers in refining units and greatly reduces energy utilization efficiency. In severe conditions, it can even cause line clogging. Grease dirt depositing in the low-temperature heat cycle system also brings unexpected difficulty and danger to overhauling of system equipment and pipelines (electrogas welding can cause fire or even explosion).
Traditional filter types (such as sand filters, fiber filters, etc.) are difficult to adapt to the purification of oily sewage. Sometimes they lose efficacy because filtering media is polluted by grease dirt.
Our HY-200DR-X-II type oil-removal purification system effectively addresses these challenges with advanced interception technology.
The HY-200DR-X-II type oil-removal purification system delivers exceptional performance in treating low-temperature thermal circulating water with minimal resource consumption.
