Beijing Oriental Chemical Plant was founded in 1978, covering an area of 1.28 million㎡. It had 1,847 employees and the original value of fixed assets is 4.8 billion RMB. With the upgrading of Beijing's industries and the construction of Beijing's urban sub-center, it has become part of the "two belts, one ring, one center" greening layout. The project was completed in October 2017.
The plant covers an area of 50 hectares. On September 16, 2018, the company entered the construction site, with the aim of building a world-class ice and snow sports training base，carrying out demolition construction and resourceful disposal of demolition waste. The company's efforts in environmental protection and integrated technology of "intelligent demolition and waste resource disposal" have been unanimously recognized and praised by the State General Administration of Sports and the industry.
Yanshan Petrochemical Company, which belongs to Sinopec Group, was founded in 1967 and has 63 sets of production units. It is one of the 12 10-million-ton refineries and 10 large-scale ethylene units of Sinopec. By the end of 2020, the company had processed 356 million tons of crude oil and produced 24,255,800 tons of ethylene. This project dismantles a total of more than 4,000 tons of copper benzene unit and 900 tons of propane unit.
The whole plant covers an area of 180,000㎡. The facilities that have been demolished includes: finished product tank area, new PO tank area, EO tank area, new nitrogen station and other large area plant supporting facilities and main buildings. The construction period was 130 days, and the entire demolition project was fully handled with intelligence, which improved the efficiency of the construction and personnel safety.
On February 26, 2019, the project utilized an advanced intelligent command platform to carry out intelligent demolition construction of gas cabinets and vapor extraction units in the old plant area. The application of the firefighting robot not only greatly reduces the workload of personnel, but also independently determines the actual dangerous situation source for data collection, processing, transmission feedback and fire extinguishing through its self-contained functions.
