The Eagle Power Explosion-Proof Industry Alliance has developed explosion-proof elevators for customers in the petrochemical industry.
Taking the ethylene project in the petrochemical industry as an example, the petrochemical base includes: ethylene unit and butadiene extraction unit, cracking gasoline hydrogenation unit, aromatics extraction unit, EO/EG unit, gas phase mLLDPE unit, LAO (α-olefin) unit, ID isomerization and disproportionation unit, SHF hydroformylation unit, PAO (poly α-olefin) unit, PP (polypropylene) unit, ethylbenzene unit, SMPO (styrene-propylene oxide) unit, POD unit-DMC method polyether polyol, POD unit-DMC-based polymer polyol, MTBE/butene-1 unit and other 16 production units, as well as supporting public works and storage and transportation systems including raw material tank area, intermediate product tank area, product tank area, power station, air compressor, circulating water field, power supply system, fire protection system, explosion-proof elevator, etc.; auxiliary supporting facilities include sewage treatment, flare system, chemical warehouse, central control room, comprehensive production office building, etc. The off-site supporting projects include raw material and product docks, inter-plant pipelines, and external power supply access to external lines. The company will build a bisphenol A unit (including the bisphenol A intermediate tank area), a diphenyl carbonate unit (including the DPC intermediate tank area), and a polycarbonate unit (including PC product packaging and warehouse), and provide supporting public works and auxiliary facilities, including a newly built circulating water field, high-salt wastewater treatment facilities, storage and transportation facilities, a joint control room, etc.
