20090062589 | Metathesis Unit Pretreatment Process with Formation of Octene - Disclosed is a process for integrating a butene dimerization process with a metathesis process to remove isobutene from the feed stream to the metathesis reactor. The isobutene is preferentially dimerized in the dimerization process to leave n-butenes for metathesis with ethylene. An upstream selective hydrogenation process also isomerizes 1-butenes to 2-butenes which is the preferred butene reagent in the metathesis process. A common fractionator column for the dimerization and hydrogenation processes is also described. | 03-05-2009 |

20100041936 | MELT-CRYSTALLIZATION SEPARATION AND PURIFICATION PROCESS - Processes for separating a solid from a solids-liquids slurry under conditions that prevent ingress of molecular oxygen are advantageous where the presence of molecular oxygen would otherwise reduce efficiencies, contribute to limited product yields, and potentially compromise safe operation of the process or downstream unit operations. Among the various embodiments disclosed herein, is a process utilizing filter columns as solid-liquid separators in combination with crystallization and reslurry unit operations to recover a product component from an initial feed mixture of miscible components. Embodiments of the disclosed processes may include the separation and purification of a product component using a crystallizer in series with a filter column followed by a chemical reactor, using a reslurry drum in series with a filter column, and using a combination of crystallizers and/or reslurry drums in series with at least one filter column. The use of filter columns in such processes is particularly attractive because these columns, when operated under the conditions disclosed herein, limit the undesirable ingress of molecular oxygen into the various process streams, and further improve process efficiencies related to both product component recovery and operating costs. | 02-18-2010 |
