METHOD AND SYSTEM FOR REMOVAL OF FOULANT PRECURSORS FROM A RECYCLE STREAM OF AN OLEFINS CONVERSION PROCESS |
摘要 |
A post fractionation process for removing heavy hydrocarbons from the C4+ olefins conversion process reactor effluent, which act as foulants when recycled to the C4+ olefins conversion reactor. This simple and effective process improves the run length of the reactor by reducing catalyst fouling, which also improves yields in a C4+ olefins conversion process to light olefins. Essential to present invention is the efficient recycling of a hydrocarbon stream to the reactor, utilizing well proven equipment in a novel way to separate more valuable product from less desirable components in the recycle product stream.
