Apparatus For Preparing Polyolefin Products And Methodology For Using The Same

View page
US Patent:
6777506, Aug 17, 2004
Filed:
Jan 15, 2004
Appl. No.:
10/757748
Inventors:
Daniel Herndon - League City TX
James G. Wakeland - Humble TX
Gilbert Valdez - Pearland TX
Assignee:
Texas Petrochemicals, LP - Houston TX
International Classification:
C08F 240
US Classification:
526 64, 526 88, 526133
Abstract:
Apparatus for olefin polymerization includes a plurality of shell and tube olefin polymerization reactors, each of which has an olefin polymerization reaction mixture inlet connection and a crude polyolefin product outlet connection. Each reactor is equipped with a recirculation system including a pump arranged to circulate a reaction mixture through the tube side of the reactor independently of the introduction of olefin polymerization reaction mixture into the reactor. The apparatus also includes an inlet reaction mixture distribution manifold and an outlet polymerization reaction mixture collection manifold interconnecting the reactors for operation in parallel. The apparatus also includes catalyst composition and catalyst modifier inlets for each reactor arranged such that a catalyst modifier to may be introduced into each reactor at a rate which is independent of the introduction of catalyst composition. The apparatus further incorporates a crude polyolefin product catalyst removal and wash system including a plurality of settler vessels, associated piping and an inlet for a catalyst killing agent. This crude polyolefin product catalyst removal and wash system operates to receive crude polyolefin product from the crude polyolefin product outlet and remove residual catalyst therefrom.

International Classification:
C08F 110/10
US Classification:
5263487, 585 18
Abstract:
A relatively low molecular weight, mid-range vinylidene content PIB polymer product and a process for making the same. At least about 90% of the PIB molecules present in the product comprise alpha or beta position isomers. The vinylidene (alpha) isomer content of the product may range from 20% to 70% thereof and the content of tetra-substituted internal double bonds is very low, preferably less than about 5% and ideally less than about 1–2%. The midrange vinylidene content PIB polymer products are prepared by a liquid phase polymerization process conducted in a loop reactor at a temperature of at least 60 F. using a BF/methanol catalyst complex and a contact time of no more than 4 minutes.
