摘要： In a system for thermal cracking gaseous feedstocks, the system including a gas cracker for producing an effluent comprising olefins, at least one transfer line exchanger for the recovery of process energy from the effluent and a water quench tower system, a process for extending the range of system feedstocks to include liquid feedstocks that yield tar is provided. The process includes the steps of injecting a first quench fluid downstream of a primary transfer line exchanger to quench the process effluent comprising olefins, separating in a first separation vessel a cracked product and a first byproduct stream comprising tar from the quenched effluent, directing the separated cracked product to a water quench tower system and quenching the separated cracked product with a second quench fluid to produce a cracked gas effluent for recovery and a second byproduct stream comprising tar. An apparatus for carrying out such process is also provided.

摘要： The present invention provides an integrated system for producing ethylene and propylene from an oxygenate to olefin (OTO) reaction system and a steam cracking system. In a preferred embodiment, at least a portion of an effluent stream from a steam cracking furnace is combined with at least a portion of an effluent stream from an OTO reaction system. Preferably the combined effluent stream is processed by one or more quench units, compression units, and/or fractionation columns. By integrating a steam cracking system with an OTO reaction system, equipment count can be reduced at a significant commercial savings. Compressor efficiency per pound of ethylene and propylene can also be advantageously increased over conventional steam cracking systems. Moreover, the amount of pollutants produced per pound of ethylene and propylene produced can be significantly reduced over the amount of pollutants produced per pound of ethylene and propylene produced in a steam cracking system.
摘要翻译：本发明提供了一种用于从含氧物到烯烃（OTO）反应系统和蒸汽裂解系统生产乙烯和丙烯的集成系统。在优选的实施方案中，来自蒸汽裂解炉的至少一部分流出物流与来自OTO反应系统的至少一部分流出物流合并。优选地，组合的流出物流由一个或多个骤冷单元，压缩单元和/或分馏塔进行处理。通过将蒸汽裂解系统与OTO反应系统集成，可以显着降低设备数量。与常规蒸汽裂解系统相比，每磅乙烯和丙烯的压缩机效率也可以有利地提高。此外，生产的乙烯和丙烯每磅产生的污染物的量可以比蒸汽裂解系统中生产的每磅乙烯和丙烯产生的污染物量大大减少。

摘要： The present invention provides new highly-efficient separation processes and systems for separating polymerization-grade ethylene and propylene from an initial effluent stream comprising ethane, ethylene, propylene, dimethyl ether, and one or more of propane, acetylene, methyl acetylene, propadiene, methane, hydrogen, carbon monoxide, carbon dioxide and C4+ components. In one embodiment, the initial effluent stream is provided from a methanol-to-olefin reaction system. It has been discovered that an efficient separation of these components is realized when DME is partially removed in a first separation step comprising methanol and water washing steps, followed by separation of the remaining components in additional separation steps.
