AROMATICS ALKYLATION PROCESS |
摘要 |
In a process for alkylating an aromatic hydrocarbon feedstock with an olefin feedstock, at least one of the aromatic hydrocarbon and olefin feedstocks is passed through a pretreatment unit containing an adsorbent such that the adsorbent removes impurities contained by the feedstock. Passage of the at least one feedstock through the pretreatment unit is then terminated and a heated inert gas is passed through the pretreatment unit such that the inert gas desorbs impurities from the adsorbent to produce an inert gas effluent stream containing the desorbed impurities. A condensable fluid is added to at least part of the inert gas effluent stream such that at least a portion of the impurities contained therein condense with said fluid to leave a purified inert gas stream, which is recycled to the pretreatment unit. |
