By the end of October, the energy consumption of Jingmen Petrochemical Ketone Heavy Duty Unit dropped to 100kg/t for the first time, hitting the highest level in history, and after the first domestic “positive sequence” process was put into use, energy consumption achieved “three consecutive falls”. .
Jingmen Petrochemical Ketone Benzene Heavy Duty Unit is one of the few refineries that can produce ultra high viscosity index lubricating oil base oil (VHVI) and high viscosity index lubricating oil base oil (HVI), producing HVI120BS, HVI150BS high-grade lubricant base Oil fills the domestic gap. Just two years ago, the keto-benzene heavy-duty unit that created better results was a large energy consumer, and the energy consumption of the unit was always “high” at around 200 kg/day standard oil.
In June 2006, Jingmen Petrochemical Co., Ltd. carried out the adaptation of the lubricants. The device successfully used the first "reverse sequence and ordering" process in China, and the energy consumption of the device was reduced by 80 units. To take this opportunity, they established a “team energy management person in charge” system to decompose the annual energy consumption indicators of the equipment, and each team defined the responsible persons of water, electricity, gas, and fuel, and carried out energy-saving labor in the team. In the competition, there will be inspections, analysis, notifications, assessments and rewards and punishments. Through horizontal and vertical comparisons, the staff can find a good point in the device's energy consumption management network, set a good position, and form a good energy-saving competition atmosphere with “there are indicators in everybody’s heart and shoulder responsibility”.
Since the beginning of this year, they have again seized the energy-saving bottleneck problem of “low yield of high-viscosity base oils” and actively carried out technological research. In the production of processed HVI500N raw materials, by reducing the temperature of the deoiling and crystallization process, a section of filtrate was used for dewaxing for secondary dilution, and the “full filtrate recycling” process was perfected, so that the yield of HVI500N increased by 7.49% year-on-year. Sleeve crystallizer is regularly and extensively defrosted and depressurized to reduce the production fluctuation caused by casing pressure, and strict adjustment is made to the adjustment range of the key process parameters of the squadron, so that the steady rate of the device is kept above 90%. In the first 10 months of this year, under the unfavorable situation of limited production, the energy consumption index of the device continued to decline, not only falling below the integer mark of 100 kg of standard oil/ton, but also decreasing by 17 compared to 2006 and 2007 respectively. Units and 3 units, after the transformation of the device energy consumption "three consecutive down."

Paper Folder

File folders can be made from plastic or paper. When paper is used, it is preferable that it is made from paper pulp with long cellulose fibre, such as kraft paper or manila paper.
Elimination of paper records, and the file folders used to organize these is a goal of the paperless office. Document imaging through document capture software remains a finicky, labor-intensive process and in many circumstances is not yet cost effective compared to traditional paper-based filing systems, especially for archival materials; archival records often end up boxed in Bankers Boxes packed with file folders in secure storage facilities, with a retrieval latency of hours to days.
