Energy Efficient Process For Producing High Purity Paraxylene

View page
US Patent:
6565653, May 20, 2003
Filed:
Dec 18, 2001
Appl. No.:
10/025153
Inventors:
Richard A. Wilsak - Naperville IL
Assignee:
BP Corporation North America Inc. - Chicago IL
International Classification:
C30B 700
US Classification:
117 68, 4222451, 585412
Abstract:
The invention is a novel energy efficient process to produce high purity paraxylene from a feed comprising at least 55 to 60 wt % paraxylene, wherein a first portion of high purity paraxylene product is obtained in a first crystallization step at about 10Â F. to about 55Â F. without the need for further reslurry and recrystallization, and wherein another portion of the high purity paraxylene product is obtained following a reslurry step which warms crystalline paraxylene obtained from subsequent lower temperature crystallizations to yield a slurry at a temperature of about 10Â F. to about 55Â F. without the need for further refrigeration.

Para-Xylene Production Process Integrating Pressure Swing Adsorption And Crystallization

View page
US Patent:
6600083, Jul 29, 2003
Filed:
Jul 10, 2001
Appl. No.:
09/901735
Inventors:
Ruth Ann Doyle - Oswego IL
Jeffrey T. Miller - Naperville IL
Richard A. Wilsak - Naperville IL
Scott A. Roberts - Naperville IL
Giorgio Zoia - Chicago IL
Assignee:
BP Corporation North America Inc. - Warrenville IL
International Classification:
C07C 714
US Classification:
585828, 585812, 585813, 585814, 585815, 585820, 585825, 585847
Abstract:
A pressure swing adsorption process to separate para-xylene and ethylbenzene from C aromatics which uses a para-selective, non-acidic, medium pore molecular sieve of the MFI structure type and is operated isothermally in the vapor phase at elevated temperatures and pressures is integrated with crystallization to produce para-xylene product. A fixed bed of adsorbent is saturated with pX and EB, which are preferentially adsorbed, the feed is stopped, and lowering the partial pressure desorbs the pX and EB. The process effluent, which is rich in pX and EB, is crystallized to obtain para-xylene product.

US Patent:
8211319, Jul 3, 2012
Filed:
Sep 16, 2003
Appl. No.:
10/663918
Inventors:
Richard A. Wilsak - Naperville IL, US
Scott A. Roberts - Naperville IL, US
Dean B. Comstock - Batavia IL, US
Ronald Stefanski - Aurora IL, US
George A. Huff - Naperville IL, US
Assignee:
BP Corporation North America Inc. - Houston TX
International Classification:
B01D 37/00
C07C 7/14
US Classification:
210767, 210808, 585812, 585814
Abstract:
A process for separating solids from liquids in a filtration zone defined by a higher concentration zone and a lower concentration zone separated by a filter. The process includes the steps of directing a slurry feed comprising a liquid and solids into the higher concentration zone, directing a displacement fluid to the higher concentration zone and passing at least a portion of the liquid through a filter to the filtrate zone, producing a filtrate.

Melt-Crystallization Separation And Purification Process

View page
US Patent:
8530716, Sep 10, 2013
Filed:
Aug 14, 2008
Appl. No.:
12/191745
Inventors:
Richard A. Wilsak - Naperville IL, US
Scott A. Roberts - Naperville IL, US
Rose M. Janulis - Oak Brook IL, US
Assignee:
BP Corporation North America Inc. - Houston TX
International Classification:
C07C 7/14
US Classification:
585812, 585815, 585814
Abstract:
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.

Olefin Purification By Adsorption Of Acetylenics And Regeneration Of Adsorbent

View page
US Patent:
61245178, Sep 26, 2000
Filed:
May 21, 1998
Appl. No.:
9/082707
Inventors:
Mark P. Kaminsky - Winfield IL
Shiyou Pei - Naperville IL
Richard A. Wilsak - Naperville IL
Robert C. Whittaker - Villa Park IL
Assignee:
BP Amoco Corporation - Chicago IL
International Classification:
C07C 700
C07C 712
US Classification:
585829
Abstract:
Processes using heterogeneous adsorbents are disclosed for purification of relatively impure unsaturated hydrocarbons such as olefins, which are typically produced by thermal cracking of suitable hydrocarbon feedstocks, by passing a feed stream, containing acetylenic impurities, and, optionally, saturated hydrocarbon gases, through a particulate bed predominantly comprising a support material having high a surface area on which is dispersed at least one metallic element. Adsorption is carried out in an essentially dihydrogen-free atmosphere within the bed, effecting selective and reversible adsorption and/or complexing of the contained acetylenic contaminants with the adsorbent, thereby obtaining purified effluent which contains less than a predetermined level of the acetylenic impurities. Selective and reversible adsorption and/or complexing of the contained acetylenic impurities with the adsorbent is continued until levels of acetylenic impurities in the effluent stream increase to a predetermined level. Thereafter, the resulting bed of adsorbent is regenerated in the presence of a reducing gas containing dihydrogen to effect release of the contained acetylenic impurities from the adsorbent.

International Classification:

C07C 712
US Classification:
585829
Abstract:
Processes using heterogeneous adsorbents are disclosed for purification of olefins such as are typically produced by thermal cracking of suitable hydrocarbon feedstocks, by passing a stream of olefin having from 2 to about 8 carbon atoms, containing acetylenic impurities having the same or similar carbon content, and optionally saturated hydrocarbon gases, through a particulate bed of predominantly a support material having high surface area on which is dispersed at least one metallic element. Adsorption is carried out in an essentially dihydrogen-free atmosphere within the bed, selective and reversible adsorption and/or complexing of the contained acetylenic contaminants with the adsorbent, and thereby obtain purified effluent which contains less than a predetermined level of the acetylenic impurities. Selective and reversible adsorption and/or complexing of the contained acetylenic impurities with the adsorbent is continued until levels of acetylenic impurities in the effluent stream increase to a predetermined level. Thereafter the resulting bed of adsorbent is regenerated in the presence of a reducing gas containing dihydrogen to effect release of the contained acetylenic impurities from the adsorbent.
