\"Energy-saving Tips\" for the Air-Cooled Condenser System at WeiHua – Author/Source: WeiHua Group; Date: 2022-05-26; Clicks: 12. In 2022, WeiHua Company further improved its green and low-carbon circular economic model. To increase the use of renewable energy, the ethylene glycol production facility carried out upgrades to create a green and intelligent factory by focusing on improving the efficiency of mechanical equipment, optimizing the process systems, and providing training for skilled operators. Among them, the air-cooled condenser system, which reduces the temperature of the tube bundle by drawing in cold air to achieve cooling through circulation and is regarded as the heart of the process system, makes a particularly significant contribution to energy savings. Since Binzhou is located in a dry plateau and gully area with insufficient annual precipitation and uneven distribution of rainfall, Xinnmin Town features a terrain that is higher in the north and lower in the south, with a combination of slopes and plateaus, numerous gullies, and inadequate water management facilities; it is therefore a typical area facing water shortages. From the initial stages of project planning, an air-cooled condenser system was chosen for cooling, primarily because air-cooled fans have a simple structure, excellent water-saving properties, cause little environmental pollution, and offer good heat exchange efficiency. Striving for excellence: optimizing processes and improving efficiency. \"In the past, we could only control energy consumption and ensure the proper operation of the units by optimizing pipeline design, conducting regular inspections to prevent leaks, and having operators manually adjust the exhaust pressure.\" Now, through precise scientific calculations based on the ambient temperature, we indirectly start and stop the fans to keep the units running, which not only saves labor and effort and reduces hassle but also contributes to energy conservation and reduced consumption at the level of basic operations. ”Chen Yongqiang, who was a complete novice just a couple of years ago but has now grown into a key member of the team, said this while staring intently at the screen. “Here, in spring, willow fluff floats in the air, and in summer dust accumulates. Additionally, the strong ultraviolet radiation and high temperatures during summer in these areas affect the cooling effect; as a result, the cooling capacity of the air-cooling fans is reduced, which leads to an increase in exhaust pressure and may cause the unit to shut down. In severe cases, this can even result in the explosion-proof membrane breaking, affecting the safety and economic efficiency of the unit. However, with the continuous improvement of these devices, air-cooled cleaning systems are also being developed more rapidly, which enables external assistance to be utilized for controlling energy consumption and thus ensuring the stable operation of the units. ”Speaking of these, shift leader Wang Xudong grew excited, his eyes filled with endless optimism for the project’s future development. Tailored solutions for energy efficiency in equipment: The power consumption of air-cooled condenser systems affects a company’s production costs and investment returns. By optimizing the design of these systems, as well as improving their operation management and maintenance, significant improvements in operational efficiency can be achieved. “Wu Zaike, please calculate now whether, if we shut down two fans, the current weather conditions will still be sufficient to meet the normal demand. ”“The operating speed of one fan is 1500 r/min, with an exhaust pressure of around 15 KPa; this not only meets the requirements but also leaves some headroom. But theory ultimately needs to be put into practice; I’ll start by trying to shut down one unit first, and then adjust the frequency. ”Wu Zaike returned to the office, out of breath, and began to calculate intensively. “This 15KW fan saves approximately 360 kWh of electricity per day; together with nearly a hundred other fans such as those used in the CO compressor, H2 compressor, and DMO distillation units, as well as losses related to power transmission and distribution, this results in savings of over 100,000 yuan per month. This represents a significant amount of money saved for the company. ”Every time Yao Junping, the deputy director of the workshop’s equipment department, comes for discussions, one of the main topics is how to improve the infrastructure in order to make a modest contribution to helping the company save energy and reduce consumption. He often says that the facilities are now operating stably at a basic level, and what the workshop can do is to adopt a meticulous and thorough approach, striving for perfection, in order to enhance operational efficiency. To date, the ethylene glycol production plant has for 3 months now consumed less electricity than the company’s set targets, while continuing to operate at high capacity and high output levels; its daily production exceeds 1,000 tons, thus exceeding the monthly production targets. Without taking small steps, one cannot reach a thousand miles. Without the accumulation of small amounts, rivers and seas cannot be formed; the ethylene glycol production plant will surely strive to save every unit of coal used and make the most of every kilowatt-hour of electricity consumed. It will accelerate efforts to control energy consumption, implement the plans for state-owned enterprise reform, and contribute new strength at the grassroots level to energy conservation and reduction.
