Assignee:

MARATHON GTF TECHNOLOGY, LTD. - Houston TX
International Classification:

C07C 17/00
C07C 1/00
US Classification:

570255, 585641
Abstract:

Processes and systems for drying liquid bromine utilizing two fractionators to produce a substantially dry liquid bromine stream and a substantially bromine-free water stream. Wet bromine liquid may be conveyed to a first fractionator wherein a substantially dry bromine liquid is produced, while a vapor stream from the first fractionator may be condensed into a first liquid phase comprising bromine saturated with water and a second liquid phase comprising water saturated with bromine. The water saturated with bromine may be conveyed to a second fractionator to produce at least substantially bromine-free water.

US Patent:

20130156681, Jun 20, 2013
Filed:

Dec 4, 2012
Appl. No.:

13/705111
Inventors:

Anand Moodley - Mpumalanga, ZA
Yijun Liu - Houston TX, US
Assignee:

MARATHON GTF TECHNOLOGY, LTD. - Houston TX
International Classification:

C01B 7/09
C07C 1/30
US Classification:

423500, 585310, 422162
Abstract:

Processes and systems that include use of a packed wet oxidation reactor for oxidizing aqueous metal bromide salts in a bromine-based process for converting lower molecular weight alkanes to higher molecular weight hydrocarbons. A stream comprising a dissolved metal bromide salt may be oxidized in a wet oxidation reactor comprising a packed section to produce at least a partially oxidized liquid stream comprising oxidized products of the metal bromide salt and a gaseous bromine stream comprising elemental bromine.

Vaporization Of Liquid Halogen By Contact With A Preheated Gas

US Patent:

20130178675, Jul 11, 2013
Filed:

Jan 3, 2013
Appl. No.:

13/733449
Inventors:

Anand Moodley - Secunda, ZA
Yijun Liu - Houston TX, US
Joseph M. Gondolfe - Magnolia TX, US
John J. Waycuilis - Cypress TX, US
Assignee:

MARATHON GTF TECHNOLOGY, LTD. - Houston TX
International Classification:

C07C 1/30
US Classification:

585310, 25218313, 422649
Abstract:

A method is provided for vaporizing a liquid elemental halogen. A heating gas is preheated in the absence of halogen to a preheat temperature which results in a preheated heating gas. The preheated heating gas is directly contacted with a feed of a liquid elemental halogen and heats the feed to a vaporizing temperature sufficient to vaporize at least a portion of the feed to a quantity of an elemental halogen vapor. A gas mixture results which includes the heating gas and the quantity of the elemental halogen vapor.

Managing Make-Up Gas Composition Variation For A High Pressure Expander Process
view source
US Patent:

20200064061, Feb 27, 2020
Filed:

Jul 30, 2019
Appl. No.:

16/526441
Inventors:

Yijun LIU - Spring TX, US
Fritz PIERRE, JR. - Humble TX, US
International Classification:

F25J 1/00
F25J 1/02
Abstract:

A method for liquefying a feed gas stream. A refrigerant stream is cooled and expanded to produce an expanded, cooled refrigerant stream. Part or all of the expanded, cooled refrigerant stream is mixed with a make-up refrigerant stream in a separator, thereby condensing heavy hydrocarbon components from the make-up refrigerant stream and forming a gaseous expanded, cooled refrigerant stream. The gaseous expanded, cooled refrigerant stream passes through a heat exchanger zone to form a warm refrigerant stream. The feed gas stream is passed through the heat exchanger zone to cool at least part of the feed gas stream by indirect heat exchange with the expanded, cooled refrigerant stream, thereby forming a liquefied gas stream. The warm refrigerant stream is compressed to produce the compressed refrigerant stream.
