[] [Font size] [] Technology Daily Beijing November 17th (Reporter Qijian) China Petrochemical Announcement However, the crude oil can be directly converted to chemicals such as ethylene, propylene (ie "oil conversion"), realizing nearly 50% of the domestic industrial application of crude oil steam cracking technology, chemical product yield, and significantly shortening production processes, reducing production costs , Emission reduction of carbon dioxide. Sinopec, the crude oil steam cracking technology to achieve industrialized application is one of the "oil transformation" routes. It "skip" traditional crude oil refining process, directly converting crude oil into chemicals such as ethylene, propylene, equivalent to wheat province Go to the middle link of the flour, do it directly into a bread. This will greatly shorten the production process, reduce production costs, and significantly reduce energy consumption and carbon emissions. At present, the world is only Exxon Mobil, and China’s petrochemical success has achieved the industrial application of this technology.

　　The technology was completed by the Beijing Institute of Chemical Engineering, China Petrochemicals, Engineering Construction Co., Ltd., And launched industrial experiments in Tianjin Petrochemical. At present, 45 Chinese invention patents have been applied, 1 international invention patent.

After calculating, the technology can be applied for each 100,000 tons of crude oil, can produce nearly 500,000 tons of chemicals, of which high value products such as ethylene, propylene, light aromatics and hydrogen are nearly 400,000 tons, and the overall technology is internationally advanced, economic value huge. It is reported that ethylene is known as the "mother of petrochemical industry", which is an important sign to measure a national petrochemical development level. And usually the raw materials required for ethylene and propylene production need to be refined from the crude oil refining process of the refinery, the production process is long, and only 30% of the crude oil is used to produce chemical raw materials.

　　In April 2021, China’s Petrochemical Research Institute was developed by the Petrochemical Sciences Research Institute, which was developed by the Petrochemical Science Research Institute. Leader. As with the crude oil vapor cracking technology, the production of chemicals produced is around 50%.

The above two techniques are expected to increase the total amount of chemicals produced by crude oil to more than 70%, which will become a possible technology route for the future "oil conversion" economy.

　　Wang Zongzong, deputy chief engineer of Petrochemical, revealed that next China Petrochemical is prepared to carry out millions of tons of crude oil steam cracking from Xinjiang Tower River, and build an "oil conversion" industry demonstration device. (Editor: Sun Dan).

Skill training enhancement skills "’mud mousse’ transfiguration expert" with shovel to mix the concrete uniform, then load into the bucket, then fill the load column template in the bucket … 6 in the morning, Longyan, Fujian Shanghang County Tongxian TownMason Zou Wenhao has started working for a day."The concrete column that is poured is most strong!" Engaged in construction industry for more than 30 years, Zou Wenhao summed up a set of methods, "How to match different ingredients, how much water, how to pour, how to make a good condition, any problem, willAffect the quality of the load column, which in turn destroys the stability of the house. "For a while, Longyan City launched a rural construction craftsman training course, inviting college experts, professional construction engineers, rural planners, etc. to class.Zou Wenhao also entered the training class.

Construction map reading, engineering instrument, rural people’s site site … Zou Wenhao thumbs up: "After so many years of house, the first truly understand this is." Wu Yingxiong, Professor, Civil Engineering, Fuzhou University, is this training A team of teachers in the class.

"The rural craftsman has a craft, but lacks system study, and it is necessary to carry out a good country’s craftsman training." Wu Yingxiong said.

In recent years, similar training activities have been carried out from all over the world: It is understood that since 2014, Hainan Province has accumulated the provincial construction craftsman training class 146; in recent years, Linyi City, Shandong Province has trained nearly 90,000 artisans, distributed " Village and Town Architecture Craftsman Continuentary Education Certificate; 10,000 copies in Jiangxi Province have also begun to promote the training of rural architecture craftsmen in the province, nearly 400 in advance training … In the new project project in progress, Zou Wenhao has replaced the professional drawings drawn by advance planning. Common sketch, use the level to reduce the error from the centimeter level to millimeter level, and use the new learning knowledge to use the new studies … How many years of construction partners will look at Zou Wenhao’s changes in the eyes, laugh, lamented: "This ‘muddyard’ transformed expert!" "" Carrying out a rural construction craftsman training, learning technology is only one aspect, more importantly, the training of planning awareness. "Associate Professor, Fuzhou University Building and Urban-Rural Planning College, first-class registered architect Ji Hong Said, "To enhance the overall consciousness of the craftsman in planning construction, put your own project into the beautiful village blueprint of the construction of ecological livable," Renovation of the old house "," more confident, good days ", walk into Shandong Linyi The villagers of the Madun Cliff Village, Xuezhuang Town, Feixian Xuezhuang, and the courtyard clean, and the house was light and bright. The flowers in front of the house were blooming.

Two years ago, Quan Zhan also lived in the vintage hub house left by the ancestors. An old photo left the old house: the sloping hull wall, the broken roof can only cover the rain with wild grass … Lu Ziyou’s construction team, which took the initiative to take the dangerous house transformation of Yan Zhulan.

At first, Yan Xianglan did not want to implement the transformation, Lu Ziyou and the workers patiently explained the safety knowledge of houses, and took out the design drawings. At the painting, listening to the plan, I met the Lan to change my idea, and a family bid farewell to the hub room.

As of the end of 2020, Linyi City has implemented thousands of rural dilapidated houses.

"Safeguarding the renovation of rural dilapidated houses to practice, achieved effectiveness, causing the country to build a craftsman.

Li Aijun, deputy director of Linyi City and Rural Construction Service Center, said.

In Longtang Town, Haiyou Qiongshan District, Hainan Province, villagers, houses, lanes, production utensils, mostly used local volcanic stone. However, due to the lack of funds and skills, the residential buildings have been built by a slightly constructed stone.

Du Xiui, a villager of Dragon New Village Committee, Longtang Town, said: "The previous old house has been spent for decades, and the east is leaking, the west is the wind, and the typhoon day is most worker.

"In recent years, Hainan Province combines poverty to the poverty to the rural dilapidated house, re-adjustment, improved the village plan." The drawings, funds and government transformed in dangerous houses, I only need peace of mind. "Local craftsman Wu Jiacai said, under the guidance of the government, he and the workers actively assume the renovation task in the village in the village." Live in a new house, more confident, good days.

Du Xiui took a reporter, looked out of the new house, and the simple smile has been hanging on the face. Today’s village is clean and beautiful, the foot is the village road in the volcanic stone, the porous volcanic stone is almost one Grinding is shining; the road is a ten-meter-high flood flood building. The first floor does not have a wall, the ventilation is excellent. The old people in the village will be cool downstairs … Xiaoqiao ancient road beautiful home "countryside should be beautiful, there is a creative" Mengshan hinterland, Liujiazhai Village, Xuezhuang Town, Linyi County, Shandong is situated in this. In the past, the village is a gravel, native pile, road potholes uneven, pedestrians are inconvenient. Please have a group of construction craftsmen to participate in environmental remediation, Flat road, cover new building, village village show new color.

"The country is beautiful, but also have creativity. We will pick it up, abandoned the grinding disc, the foreign wood paved the bridge, picked up the stone tablets and put it out, the cost is not high, and there is a feature.

"Lu Ziyou introduced," the people have a new look of housing, we have to keep up with the times. "

The beauty is drunk tourist, the people are rich in pockets.

In recent years, Liu Jiazhai Village not only comes to the provincial-level beautiful rural demonstration villages, but also planned to build a special tourism project. Visitors will come to experience, and the B & B is often full.

"From program design to later maintenance management, rural construction craftsmen are both a ‘architect’, and they have got a ‘designer’ ‘manager’, and even participated in the entire planning and construction of the country.

Gu Jachang, Associate Professor, Associate Professor of the Architecture Department of Shandong University, and cultivated the rural construction of a craftsman, to a certain extent, and revitalize the revitalization of rural cultures and the revitalization of the industry.

These years, Lu Ziyou participated in many cultural squares of the village, the construction of a rural stage, scenic spot.

"We often go to the field to study, you are in the eyes, remembering, looking for a lot of inspiration.

He smiled and said, "Headed at the village is beautiful, there are more tourists, everyone laughs, I am happy!" "" Come here, like walking into history books, it is really worthless. "

"Ms. Liu, who came to Haikou City, Samou Town, Sanmeng Town, Liantang Ancient Village, looked at the unicorn gray sculptures on the screen wall. Three years ago, in order to repair the ancient buildings in the village, Wu Jiacai tested a good job.

"Before dismantling the ancient buildings, we must first take care of its structure, divide the ancient buildings into hundreds of small items, and numbered one by one. If the item that is removed, if the item is also in line with the standard, it is necessary to recover one by one.

"Wu Jiacai said," The repair of ancient buildings is not one-time, in addition to large-scale repairs, we must often repair the small repair on weekdays.

"" Most of the rural construction craftsmen is the village. They are both a village builder, and the beneficiary of beautiful rural areas, with very strong endurance.

"Yang Wei, deputy secretary general of the Hainan Provincial Civil Engineering Society," Painting the painting of beautiful villages, can’t help the rural construction craftsman.
