Is energy consumption high in the paper industry Try to change the oil to the air compressor

The paper industry is closely related to the national economy and social development, and it is also a large traditional energy consumption and waste discharger. How to significantly reduce the industry's energy consumption and emissions through innovative means is the top priority of the industry's future development. The "Opinions of the China Paper Industry Association on the Development of the Paper Industry during the 13th Five-Year Plan" clearly stated that the paper industry should fully rely on technological progress, innovative development models, and achieve success on key issues related to the healthy development of China's paper industry, such as resources, environment, and structure. Make breakthroughs, implement sustainable development strategies, and improve sustainable development capabilities In recent years, with the continuous improvement of policies and regulations, the paper industry is gradually developing in the direction of energy saving, green and environmental protection, but this has also increased the pressure on many companies. How to achieve energy conservation and emission reduction while ensuring benefits has caused many enterprises to worry and headache. In fact, some adjustments in production links that are often overlooked can also bring huge benefits to enterprises.

　　Take air compressors as an example. Air compressors are equipment commonly used by many manufacturing companies to provide air power for the entire production process. However, air compressors are prone to various wear and failures due to long-term continuous operation. This not only gives engineers a headache, but also often inexplicable is that they often don't know where the problem is. As a large energy consumer, the power consumption of air compressors has always been at a high level in the production energy consumption of enterprises. A company located in Zhangjiagang was faced with these problems, and to their surprise, the solution was so simple.

　　 The "worries" caused by the air compressor

　　 Located in Zhangjiagang, SF Paper Products Co., Ltd. (hereinafter referred to as SF Paper Products) is a professional manufacturer in the field of packaging cartons. With advanced production technology and equipment, its annual production capacity reaches 36 million square meters, and its products are sold at home and abroad.

　　 SF Paper Products Air Compressor Station has three oil-injected twin-screw air compressors. In order to produce the three air compressors, it often takes a long time to operate. After long-term operation, the problem began to surface. The three machines often experienced serious carbon deposits in the oil and gas separator and frequent replacement. This not only caused the shutdown and economic losses caused by the air compressor problem, but also brought additional maintenance costs and Energy expenditure.

　　 On-site investigation by ExxonMobil engineers found that the problem was actually the lubricant of the air compressor. Due to the small capacity of the lubricating oil in the air compressor, the lubricating oil is in the form of mist in the screw cavity and fully contacts the hot air, which requires the lubricating oil to have excellent thermal stability and oxidation resistance. However, since ordinary mineral oil has been used for lubrication before, the exhaust temperature of the three air compressors during normal operation exceeds 90 degrees Celsius, and the maximum exhaust temperature in summer can be close to 100 degrees. Under the action of high-temperature air for a long time, the oil is easily oxidized to form a paint film, and even carbon deposits, which causes the oil and gas separator to block.

　　 In this regard, the engineers of SF Paper Products invited ExxonMobil, an expert in lubrication management, to "see a doctor" for these three air compressors and customize lubrication solutions.

　　 Let the machine regenerate

In response to the above technical problems, ExxonMobil engineers recommended to customers a Mobil Rarus? SHC 1025 synthetic lubricant specially used for screw air compressors, which is not only suitable for working under high temperature and harsh conditions, but also for oil change The long cycle allows customers to save worry and money.

Mobil Rarus? SHC 1025 synthetic lubricating oil is formulated from synthetic base oil (synthetic wax-free hydrocarbon liquid) and additive formula produced by high-tech technology. Its resistance to oxidation and heat cracking surpasses ordinary mineral oil and can effectively reduce Equipment failures can reduce carbon deposits and pollution of downstream components, thereby saving the cost and man-hours of replacing the oil and gas separator.

　　 In addition, Mobil Rarus? SHC 1025 synthetic lubricating oil has a uniform molecular size and has a smaller internal friction compared with ordinary mineral oil, so the traction coefficient is lower, which can effectively reduce friction and reduce energy consumption.

　　 A small drop of oil makes a big difference

After replacing it with Mobil Rarus? SHC 1025 synthetic lubricant, the air compressor of SF Paper Products has been operating without problems for a long time. So far, there has been no problem of carbon accumulation in the oil and gas separator, and the oil change interval has been doubled compared with the original. From twice a year to once a year. Not only that, through on-site comparison of energy consumption tests, engineers found that using Mobil Rarus? SHC 1025 synthetic lubricant instead of mineral oil can save power consumption by about 4.2% [In actual working conditions, use a digital clamp meter to compare a working condition The stable Ingersoll Rand oil-injected twin-screw air compressor (R110IU-W7.5-X) is used to measure the load current when the air compressor uses mineral oil and Mobil Rarus? SHC 1025, respectively, 211A and 201A, the power factor is 0.65. ].

Because of the extension of the oil change interval and the reduction of operating energy consumption, SF Paper products can save a lot of costs and significantly reduce emissions each year. Only three air compressors can save more than RMB 67,000 per year and save more than 67,000 kilowatt-hours (kWhr) of electricity each year. Correspondingly, an annual reduction of 56 tons of carbon dioxide emissions, while reducing the consumption of lubricating oil by 180 liters (L) [The company’s air compressor originally consumes 536,250 kWh per year, which reduces energy consumption per unit by 4.2% and the unit price of electricity is RMB 0.85 According to calculations, an average of at least 0.8356 kg of carbon dioxide is emitted per 1 kWh of power generation; the oil change system has a capacity of 60L, and the annual oil change interval of each unit is doubled; the unit price of the oil and gas separator is 2000 yuan, and the unit price of the filter is 300 yuan. 3 times reduced to once. ]. The customer commented on this: "Unexpectedly, professional lubrication solutions can bring so many benefits. Although its cost is only a small part of the total production cost, it has received many surprises. It not only solves technical problems, but also realizes Energy saving and emission reduction. It's really a small drop of oil, a big difference."
