58063390, Sep 15, 1998

Filed:

Apr 5, 1996

Appl. No.:

8/628454

Inventors:

David B. Manley - Rolla MO

International Classification:

F25J 302

US Classification:

62631

Abstract:

The present invention is an enhancement of the prior art use of partial effects and component distribution regarding NGL fractionation, especially relating to the separation of propane, isobutane, normal butane and gasoline components. The present invention distributes butanes in two separate columns and integrates the thermodynamic efficiency obtained with partial effects to cascade reboiling duty through as many as four separate columns. The resulting savings in energy are compared with the prior art process of sequential fractionation of NGL.

International Classification:

C08F 464

US Classification:

585814

Abstract:

The method for separating from a mother liquor containing at least two liquids, one of the two liquids including the steps of: (a) forming a precipitatable complex from one of the liquids and a complexing agent; (b) precipitating the precipitatable complex from the method liquor; and (c) recovering the second liquid from the remaining mother liquor. Typically, the two liquid substances are tetrahydrofuran and toluene and the complexing agent is titanium tetrachloride. The precipitatable complex is TiCl. sub. 4. 2C. sub. 4 H. sub. 8 O or TiCl. sub. 4. C. sub. 4 H. sub. 8 O. Preferably, a cooling step is included in the method to enhance the removal of the precipitatabe complex. Superfractionation of the remaining liquor in distillation columns enables one to recover toluene, hexane, titanium tetrachloride and tetrahydrofuran. An apparatus for carrying out the method of recovering solvents in also disclosed.

Inventors:

David B. Manley - Rolla MO

International Classification:

F25J 100

US Classification:

62620

Abstract:

The present invention is an improvement in distillation column interreboiling. Previously, hot bottoms streams could be used to heat interreboilers, although heat recovery was limited by approach temperatures of a stream losing sensible heat to a stream gaining sensible heat and heat of vaporization. The present invention expands the number of stages between the draw and return stages for an interreboiler, thus increasing the heat recovery from the bottom stream and reducing hot utilities to the reboiler, among other important advantages. The present invention is shown for NGL deethanization.

Appl. No.:

8/587238

Inventors:

David B. Manley - Rolla MO

International Classification:

F25J 100

US Classification:

62630

Abstract:

The present invention provides one or more sidedraws, from the stripping section of a column, of a heavy key component in the presence of a desirable heavier than heavy key component. In addition, the present invention provides one or more sidedraws, from the rectification section of a column, of a light key component in the presence of a desirable lighter than light key component. In prior art columns, an inherent remixing of the components to be separated in downstream columns occurs near the top or bottom of refluxed or reboiled columns respectively. In the prior art, a re-separation of the remixed components from an upstream column must be done in downstream columns. The present invention eliminates or reduces, according to desired optimization, the remixing by removal of the heavy or light key components in the sidedraw stream.

Inventors:

David B. Manley - Rolla MO

International Classification:

F25J 302

US Classification:

62630

Abstract:

The present invention is a set of improvements in deethanizing and depropanizing fractionation steps in NGL processing. The several embodiments of the present invention apply component distribution to multiple columns, interreboiling, intercondensing, thermal coupling and "thermo-mechanical" coupling to the commonly practiced deethanizer/depropanizer fractionation sequence of NGL processing.

International Classification:

F25J 300

US Classification:

62 20

Abstract:

A process for recovering CO. sub. 2 from a mixture of light hydrocarbons, e. g. light hydrocarbons produced from a CO. sub. 2 injection enhanced oil recovery. The mixture is distilled in a distributive zone with CO. sub. 2 produced overhead and in the bottoms. The overhead and bottoms produced from the distributive zone are then fed to first and second concentrating distillation zones, respectively. The first concentrating zone produces a bottoms product rich in CO. sub. 2 and an overhead product rich in methane and lean in CO. sub. 2. The second concentrating zone is refluxed with lean oil and produces a CO. sub. 2 distillate and a CO. sub. 2 -lean bottoms product. In various embodiments, at least a section of each of the concentrating zones are placed in a single column, the CO. sub. 2 product streams are taken as a side draw, vapor from the first concentrating zone is used in an open cycle heat pump to heat the second concentrating zone, the distributive zone is thermally coupled with one or both of the concentrating zones, and the distributive zone and certain sections of the concentrating zones are physically integrated into a single column.

International Classification:

B01D 314

US Classification:

202158

Abstract:

An integrated distillation column having a partitioned stripping or absorption section is presented. The integrated stripping/distillation column comprises a single shell housing a refluxed absorption section and a reboiled stripping section. The stripping section is partitioned by a vertical wall into first and second separate portions having upper end in fluid communication the absorption section. The stripping portions include fluid isolated lower ends having separate reboilers. In the integrated absorption/distillation column, the absorption section is partitioned and separate reflux loops are provided for each portion of the absorption section. In such a manner, a two column distillation process can be combined into one for achieving space and equipment savings.

International Classification:

F25J 100

US Classification:

62623

Abstract:

The present invention is a process of high efficiency rectification zone separation of cracked or other ethylene-containing gas chilled primarily by two closed mixed refrigerant loops and at least part of the dephlegmated overhead gas. The composition of the mixed refrigerants is optimally chosen to obtain an extremely close approach between the process condensation temperatures in the high efficiency rectification zone and the temperature of the chilling streams. An approach of about 3. degree. F. to 8. degree. F. can be achieved for the full condensation curve in the high efficiency rectification zone operating with either ethane or naphtha derived cracked gas. Highly reliable and stable operation is obtained by closed refrigeration loops in the present invention, in addition to reducing high efficiency rectification zone design cost.
