近年来埃索公司设立了专门机构开发和改进FCC工艺过程,增强其可靠性。埃索公司的灵活裂化ⅢR型装置集先进的工艺过程和高度可靠的机械设计为一体,抓住了机械设计与工艺过程密切相关的要点,实现了装置运转可靠,低维修的最优设计。 灵活裂化ⅢR型装置优良的机械特性主要有如下几个方面:①取消了催化剂循环线路的膨胀节,从而改善了循环管线的可靠性,减少了设备的维修。②所有设备,催化剂输送管线及滑阀均采用内衬里的冷壁结构。③仅把待生立管上的待生滑阀作为主控阀以调节整个系统的催化剂循环量;其他系统的催化剂循环完全由两器压力和立管及提升管的密度等自身压力平衡来调整,从而有效地
In recent years, Esso set up a special agency to develop and improve the FCC process to enhance its reliability. Esso’s flexible cracking ⅢR-type device set of advanced technology and highly reliable mechanical design as a whole, to grasp the mechanical design and process are closely related to the point, to achieve the device running reliable, low maintenance optimal design. Flexible cracking ⅢR-type device excellent mechanical properties are mainly the following aspects: ① cancel the catalyst circulation line expansion joints, thus improving the reliability of the circulating pipeline, reducing equipment maintenance. ② All equipment, catalyst delivery lines and slide valves are used in the lining of the cold wall structure. ③ only to stand on the tube stand-in spool valve as the main control valve to regulate the entire system of catalyst circulation; other systems, catalyst cycle completely by the two pressure and riser and riser density and other self-balancing pressure to adjust Thus effectively
