Recently, Jinan Refining and Chemical Company successfully developed YU18D, a special material for geotextile polypropylene (PP), which is used as the raw material for the world's first 6-meter ultra-wide PP filament geotextile production line, which can replace similar imported products.

It is understood that the ultra-wide PP filament geotextile is resistant to acid and alkali corrosion, and has high tear strength and tensile strength. The construction technology and the reduction of construction costs are mainly used in key areas of national economy and people's livelihood such as water conservancy and hydropower, aerospace, sponge city and so on.

At present, domestic ultra-wide geotextile PP raw materials rely on a relatively high proportion of imports.

To this end, Jinan Refining and Chemical Co., Ltd., in conjunction with Beijing Chemical Research Institute and Sinopec Chemical Sales North China Branch, paid close attention to customers' needs for special raw materials, targeted key production plans, repeatedly adjusted process conditions, tracked trial results in real time, and optimized and improved product performance. Produce special materials with both spinnability and mechanical properties, excellent tensile strength and burst strength.

At present, YU18D product quality is stable, customer demand is stable, and efficiency is obvious.

Jinan Refinery has 31 sets of main production units such as atmospheric and vacuum, catalytic cracking, diesel hydrogenation, countercurrent continuous reforming, lubricating oil series, and polypropylene.

The one-time crude oil processing capacity is 7.5 million tons/year, and it mainly produces more than 50 kinds of products such as gasoline, aviation kerosene, diesel, liquefied gas, road asphalt, polypropylene, lubricating base oil, etc.

The company has more than 1,900 on-the-job employees, including 7 professionals with senior professional titles, 211 with senior professional titles, and 289 with intermediate professional titles. In the skilled operation team, 21 people have obtained the professional qualifications of senior technicians, and 129 people have obtained the professional qualifications of technicians.

Over the years, Jinan Refinery has successively built Sinopec's first heavy base oil bright stock production base and environmentally friendly rubber filler oil production base, and put into operation the world's first 600,000-ton/year countercurrent moving bed continuous reforming unit, striving to build " Safe, reliable, clean and environmentally friendly” model of urban refinery, the quality and efficiency of enterprise development have been continuously improved.
