燕山石化公司30×104t/a乙烯装置1994年完成第一次扩能至45×104t/a的改造后,仍存在原料灵活性差、能耗高、与同期建设的乙烯装置比规模偏小等问题。以全面提高技术水平、降低能耗、增加原料灵活性、尽可能扩大生产能力为目标,充分考虑方案的可实施性、实施时的安全性、实施后的可操作性及方案的先进性和经济性,对装置技术改造的方案进行了比选研究。经改造,实现了生产能力扩大到66×104t/a的目标,实际可达71×104t/a,装置能耗明显下降,石脑油、轻柴油、重柴油、加氢裂化尾油均可作为乙烯原料。在世界上,首次在乙烯装置中采用混合冷剂制冷技术和碳三催化精馏加氢技术并获得成功,对世界乙烯工业技术进步有推动作用。

The objective of this study is, to interpret the influence of reinforced concrete walls addition in reinforced concrete frame structures considering behavior laws that reflects the actual behavior of such structures, by means of Castem2000computer code (pushover analysis). A finite element model is proposed in this study, using the TAKEDA modified behavior model with Timoshenko beams elements. This model is validated initially on experimental model. Then the work has focused on the behavior of a RC frame with 3 levels and three bays to better visualize the behavior of plastic hinges. Once the plastic hinge control parameters are identified (plastic rotation, ultimate curvature), a strengthening by introduction of reinforced concrete walls (RC/wall) at the ends of the reinforced concrete frame (RC/frame) has been performed. The results show that these RC walls significantly improve the behavior, by a relocation of efforts towards the central part of the beams.
