On October 11, 2024, official media outlets such as Quanzhou Evening News and Quanzhou Economic News reported on the green and energy-saving transformation efforts of the local leading petrochemical companies. One of these initiatives was the ultrasonic descaling project for refining preheaters, which enables the saving of 62,500 tons of high-pressure steam per year, equivalent to 6,112 tons of standard coal in terms of energy savings. ” The ultrasonic scale-inhibition technology used in this refined preheater is not ordinary ultrasonic technology; rather, it is a special type of ultrasonic technology – long-pulse ultrasonics. Compared to conventional ultrasonic technology, this type offers a working time that is 20-30 times longer, and the power of the transducer is 8-10 times greater, which results in better scale inhibition and removal effects. (Technical exchange WeChat: TigerPeng2014) The installation visualization of the equipment is as follows: The manufacturer’s assessment of the energy-saving effects is as follows: The economic benefits are estimated as follows: The value of steam saved is significant – 2.5 tons of high-pressure steam are saved per hour. At a cost of 250 yuan per ton, the monthly savings amount to: 2.5*24*30*250 yuan/ton = 450,000 yuan per month. Calculating on an annual basis with November as the reference point, this can result in savings of 4.95 million per year. The savings in gas costs are as follows: 368.138 m3 of natural gas can be saved per hour. At a cost of 3.2 yuan per m3, the monthly savings amount to 368.138*24*30*3.2 = 848,000 yuan per month. Calculated on an annual basis in November, this can save 9.328 million per year. In summary, by adding the two amounts together, a savings of 1.298 million units per month is achieved in terms of high-pressure steam and natural gas, which translates to approximately 14.278 million units saved per year.
