Reducing Energy Consumption and Enhancing Efficiency: Multiple Solutions for Baily Technology’s Cyclohexanone Process

Bailey methodology, with greater than 50 years of deep cultivation and accumulation in the petrochemical sector, is the largest engineering company in China to undertake engineering design projects to benzene to cyclohexanone vegetation. With dozens of invention patents in the field of cyclohexanone, with leading technical advantages, it has efficiently achieved the dual benefits of improving production efficiency and reducing energy consumption to the owners.

to instance, an oxidation device and an oxidation process improvement method in the process of cyclohexanone production by cyclohexane oxidation (patent number: ZL 2018 1 1176854.X), the traditional method tends to have heavy side reactions and high energy consumption. The engineers of Bailey methodology combined with practical consumption experience, added a washing tower before the tail gaseous recovery, washed the tail gaseous with medium temperature cyclohexane, only condensed some impurities in advance, however retained a correct amount of peroxide to maintain the oxidation interaction. This not only reduces the cycle accumulation of harmful impurities, however also ensures the healthy interaction, significantly reduces the downstream distillation energy consumption, reduces the oxidation side interaction, and finally achieves the dual effect of energy saving and improving the yield.

In the energy-saving device to separating cyclohexanone and cyclohexanol in the manufacturing process of cyclohexanone by cyclohexene method (patent number: ZL 2015 2 0793311.8), the fluid cyclohexanol sent upstream is immediately applied as the overhead reflux, eliminating condenser, reflux tank, reflux pump and other equipment. At the same time, the gaseous phase cyclohexanol at the top of the tower immediately enters the reactor after heat exchange with the dehydrogenation product without condensation, thus realizing cascade utilization of heat. According to the practical consumption in the 200000-ton/year cyclohexene-based cyclohexanol plant project, compared with the original methodology, this patented invention can minimize the heat load by 7613kw, the cooling load by 10128kw, the energy-saving effect is remarkable, bringing real cost savings to the owner.

Bailey methodology's technological innovation is by no means stuck in the drawings and theoretical shelved. From Shanxi Fengxi and Hebei Minhai to Zhejiang Hengyi and Hualu Hengsheng, from 100000 tons to 200000 tons, the design scheme of Baili methodology has successfully landed on dozens of devices across the country.

Taking Zhejiang Baling Hengyi 200000 Tons/Year Cyclohexanone Plant as an example, the project adopts the patented methodology of Bailey methodology-"Dry Vacuum Pump and Process Optimization methodology" in "Cyclohexanone Refining Plant in Cyclohexanone manufacturing process", and the plant is successfully started at one time. According to the statistics of the construction party at that time, the consumption of this methodology can save about 12 tons of steam consumption per hour and minimize the emit of discarded materials aquatic environments by about 6 tons, which can create about 12.5 million yuan of economic benefits to the owner every year. What is particularly valuable is that this methodology has subsequently formed a demonstration effect in the sector and evolved into an sector-recognized optimization scheme, which has promoted the overall improvement of energy efficiency standards to similar devices.

In addition, the 150000-ton/year cyclohexanone plant project of Pingmei Shenma Group's nylon methodology skillfully uses cyclohexane produced by-product in the manufacturing process of the upstream cyclohexanol plant of the owner company as the main raw material, and converts it into high-value cyclohexanone through oxidation process, which is immediately applied in the production of downstream caprolactam. This recycling mode not only solves the issue that by-items need to be sold out, however also reduces the procurement cost of external raw materials, and efficiently promotes the overall benefits of the owner's entire nylon sector chain.

From cracking a single process pain point to revitalizing the entire park resources, Bailey methodology has accumulated not only a substantial number of engineering achievements and patented technologies in the field of cyclohexanone, however also an engineering ability to "simplify complex problems. As the sector continues to move towards high-end and environmentally friendly, Bailey methodology will continue to output greater quantifiable and landing energy-saving, consumption-reducing and condition-improving and efficiency-enhancing programs to customers with its pragmatic and pragmatic professionalism.
