摘要： A trace amount of free chlorine, present along with comparable amounts of ethylene, oxygen and water vapor in the ethylene dichloride (EDC) effluent from a direct chlorination reactor, may be effectively scavenged by exposing the effluent to ultraviolet ("u-v") light having a wavelength less than about 4000.ANG. which is absorbed by the chlorine, but to which both ethylene and EDC are essentially transparent. In this process, contaminant chlorine in substantially pure (99..sup.+ %) EDC is catalytically activated and reacts with EDC to form an unwanted byproduct, namely 1,1,2-trichloroethane ("triane"). The process is effective in either the gaseous phase or the liquid phase.

摘要： A process is disclosed for the economical operation of a commercial ethylene dichloride (EDC) cracking furnace which typically is prone to coking of the tubes through which the EDC is flowed. The EDC cracking furnace is found to be critically sensitive to the presence of trace amounts, 30 ppm or more of FeCl.sub.3 and/or 20 ppm or more of free chlorine, which cause coking of the tubes of the furnace. The coking of the tubes is minimized by maintaining less than 30 ppm by weight of FeCl.sub.3 or less than 20 ppm of free chlorine in the EDC feed to the EDC furnace. In the particular instance where EDC is produced at least in part in a high temperature direct chlorination ("boiling") reactor constructed from mild steel, this goal requires that the chlorine content of the effluent from the boiling reactor be controlled so as not to exceed 20 ppm. But this is to be done without using more than a 2% by weight excess of ethylene over the stoichiometric amount required to produce the EDC in the boiling reactor. The goal is met by controlling the pressure drop and contact time through a polishing reactor, provided the operation of the boiling reactor is also controlled. The requirements are met with a packed bed of catalyst support having a geometry such that the outer surface area per unit volume of packed catalyst is less than 7.8 cm.sup.2 /ml and the catalyst support has a wall thickness of from about 2.5 mm to about 6.5 mm. The polishing reactor removes the FeCl.sub.3 which may be present and also allows the conversion of at least 90% of the free chlorine in the chlorine-rich EDC (100 ppm to about 3000 ppm Cl.sub.2). This results in continuous operation of the EDC furnace for much longer periods than is normal without the use of a polishing reactor.
摘要翻译：公开了一种用于商业二氯乙烷（EDC）裂解炉的经济运行的方法，其通常易于使EDC流过的管的焦化。发现EDC裂解炉对于存在微量的FeCl 3和/或20ppm或更多的游离氯的微量存在，这导致炉的管焦化，这是非常敏感的。通过在EDC炉的EDC进料中保持小于30ppm的FeCl 3或少于20ppm的游离氯，可以使管的焦化最小化。在特定情况下，EDC至少部分由低温直接氯化（“沸腾”）反应器生产，由低碳钢制成，这一目标要求将来自沸腾反应器的流出物的氯含量控制在不超过 20 ppm。但这是在不使用超过2重量％过量乙烯的情况下进行的，而不是在沸腾反应器中生产EDC所需的化学计量量。如果沸腾反应器的操作也受到控制，则通过调整抛光反应器的压降和接触时间来满足目标。满足要求的催化剂载体的填充床具有几何形状，使得每单位体积的填充催化剂的外表面积小于7.8cm 2 / ml，催化剂载体的壁厚为约2.5mm至约6.5mm 。抛光反应器除去可能存在的FeCl 3，并且还允许在富氯EDC（100ppm至约3000ppm Cl 2）中转化至少90％的游离氯。这导致EDC炉在不使用抛光反应器的情况下比正常情况下持续运行更长的时间。

摘要： The operation of a fluid-bed reactor in which the catalyst has a proclivity to stickiness deleterious to efficiently carrying out a reaction of the gaseous components fed to the reactor, is controlled by monitoring the fluctuations in temperature at various locations in the bed, and computing the standard deviation of temperature at predetermined intervals of time. When the fluid-bed consists essentially of a supported catalyst performing at peak efficiency, near which it has a proclivity to "stickiness", slight fluctuations, less than 1.degree. F., of operating temperature are correlatable to the quality of fluidization and the risk of an uncontrollable upset in the reactor.
