摘要： A process and apparatus reboil a propylene splitter bottoms by heat exchange and/or a deethanizer bottoms stream with a compressed propylene splitter overhead stream. Use of single splitter compressor and operation of the propane-propylene splitter column at lower pressure are enabled, whereas conventionally two splitter compressors and higher splitter pressure were necessary to provide a propylene product stream and a propane recycle stream of equivalent quality.

摘要： Processes for producing olefins include integration of steam cracking with a dual catalyst metathesis process. The processes include steam cracking a hydrocarbon feed to form a cracking reaction effluent containing butenes, separating the cracking reaction effluent to produce a cracking C4 effluent including normal butenes, isobutene, and 1,3 -butadiene, subjecting the cracking C4 effluent to selective hydrogenation to convert 1,3 -butadiene in the cracking C4 effluent to normal butenes, removing isobutene from a hydrogenation effluent to produce a metathesis feed containing normal butenes, and contacting the metathesis feed with a metathesis catalyst and a cracking catalyst directly downstream of the metathesis catalyst to produce a metathesis reaction effluent. Contacting with the metathesis catalyst causes metathesis of normal butenes to produce ethylene, propene, and C5+ olefins, and contacting with the cracking catalyst causes C5+ olefins produced through metathesis to undergo cracking reactions to produce additional propene, ethylene, or both.

摘要： Systems and methods for purifying crude propane streams are provided herein. For example, in some embodiments, methods are provided including passing a crude propane stream to a fixed bed reactor containing a Beta zeolite configured to reduce the propylene oxide content of the crude propane stream and produce a propylene-treated stream and contacting the propylene-treated stream with an acetaldehyde scavenger to produce a treated propane stream. In some embodiments, methods are provided including passing a crude propane stream through a water wash system to provide a treated propane stream having a lower propylene oxide content, a lower acetaldehyde content, or both.
