After seven years of technical research, the Liffert team innovatively constructed a "coalescence-separation-filtration" three-dimensional purification system. The core principle is to use the surface tension effect of oil-hydrophobic materials to condense micrometer water droplets into large water droplets visible to the naked eye, and then to achieve oil-water separation through gravity sedimentation and vacuum dehydration technology. This breakthrough design provides three core advantages: micrometer dewatering capacity Emulsified water, which is difficult to handle with conventional centrifugal dewatering equipment, can be compressed to less than 50ppm (ISO 4406) in Lifelter's equipment, which is equivalent to condensing the water in a glass of oil to the size of a grain of rice. The measured data of a refining and chemical enterprise show that after the treatment of the equipment, the service life of the lubricating oil is extended to 4 times the original cycle, and the compressor failure rate is reduced by 85%. Intelligent operation and maintenance system equipment built-in PLC intelligent control module, can real-time monitoring of oil temperature, pressure, water content and other 12 parameters, when the water concentration exceeds the set threshold, the system automatically start the sewage procedure. This "unattended" mode not only reduces the manual inspection workload by 70%, but also enables remote fault warning through the iot module, enabling equipment maintenance to shift from passive response to active prevention. The adaptability of the whole scene is from the extreme cold condition of -40℃ to the high temperature environment of 150℃. The equipment is made of 316L stainless steel and explosion-proof design to ensure stable operation in acid, alkali and corrosive media. For large refining and chemical plants, Lifeldt offers modular parallel solutions with a single unit capacity of 5,000 L/h to meet the continuous purification needs of refineries with a daily capacity of 10,000 tons.

From pain point resolution to value reconstruction In the field of lubricating oil circulation systems, coalescence dehydration technology is reshaping the logic of equipment operation and maintenance. A large compressor manufacturer has aggravated bearing wear due to excessive lubricant water content, and the annual replacement spare parts cost more than 3 million yuan. With the introduction of Liffert equipment, the cleanliness of the oil is improved to NAS Level 5, which not only extends the oil change cycle to 3 years, but also reduces energy consumption by 12% by reducing friction losses. In the fuel oil purification scenario, the technical value is further highlighted. A domestic aviation kerosene supplier uses the equipment to treat the trace water mixed in the storage and transportation process, which increases the combustion efficiency by 8% and reduces the engine carbon deposit by 40%. In the context of stricter environmental protection, this technology has become a "secret weapon" for enterprises to break through emission standards. More socially valuable is the recycling of waste oil. Liffert's coalestion-fine filtration process, developed in collaboration with the China University of Petroleum, can increase the recovery rate of waste oil from 20% to 90%, equivalent to saving the industry millions of tons of crude oil production per year. This technology not only reduces enterprise procurement costs, but also promotes the green transformation of the petrochemical industry by reducing waste oil incineration emissions.

Technology enabling Sustainable development Driven by the "dual carbon" goal, coalidating dehydration technology is becoming a win-win path for petrochemical companies to reduce costs and increase efficiency and environmental compliance. Taking a refining and chemical plant that handles 5,000 tons of lubricating oil a year as an example, after using the equipment, the purchase cost of lubricating oil is directly reduced by 1.5 million yuan, and the equipment maintenance cost is reduced by 60%. The more far-reaching impact is that by reducing waste oil emissions by 80%, the enterprise's carbon emission intensity is reduced by 15%, and the national green factory evaluation standard is reached three years in advance. Industry experts point out that the popularization of this technology will reshape the full life cycle management of petrochemical equipment. Professor Wang, dean of Chemical Equipment Research Institute of Tsinghua University, said: "Agglomeration dehydration technology has shifted oil purification from the traditional 'after-remedy' to 'pre-prevention', which brings not only economic benefits, but also a revolutionary upgrade of equipment management concepts."

When the last drop of water is coalesced and separated, the oil flows through the transparent pipe with a clear color. This is not only a victory of technological innovation, but also the epitome of the transformation of the petrochemical industry to intelligent and green. The Lifelte oil filter carries not only the micron level dehydration accuracy, but also the confidence and strength of Chinese manufacturing to break through the key fields of "jam neck" technology. In this revolution concerning energy security, technology iteration is writing a new chapter of high-quality development in the petrochemical industry at an unprecedented speed.
