57636850, Jun 9, 1998

Filed:

Aug 17, 1995

Appl. No.:

8/516227

Inventors:

Charles Joseph Kruse - Cypress TX
Kyle Lee Preston - Port Arthur TX
Brian Lawrence Benac - Austin TX

Assignee:

Huntsman Specialty Chemicals Corporation - Austin TX

International Classification:

C07C 4100

US Classification:

568698

Abstract:

MTBE is prepared from TBA and MeOH by passing a feed mixture comprising TBA and MeOH through a primary MTBE reaction zone to form a primary reaction product containing MTBE, unreacted TBA, unreacted MeOH, isobutylene and water; the primary reaction product is fractionated to provide a first lighter distillation fraction comprising isobutylene, MeOH and MTBE and a first higher boiling distillation fraction comprising MeOH, TBA and water and the first higher boiling distillation fraction is charged to a second stage MTBE reaction zone to form a second stage reaction product comprising unreacted MeOH, unreacted TBA water, isobutylene and MTBE.

International Classification:

C07C 4109
C07L 4106

US Classification:

568697

Abstract:

Methyl tertiary butyl ether (MTBE) is formed by reaction of methanol with tertiary butyl ether in two catalyst beds. A feedstock mixture comprising methanol and tertiary butyl alcohol in a molar ratio of 2 to 3 moles of methanol per mole of tertiary butyl alcohol is reacted in a first etherification reaction zone at a liquid hourly space velocity of 1 to 10 volumes of feedstock mixture per volume of catalyst per hour. A first reaction product mixture is fractionated to remove unreacted methanol, isobutylene and MTBE overhead. This isobutylene is passed to a second etherification reaction zone at a liquid hourly space velocity of 1 to 10. A second reaction product mixture is fractionated to recover additional MTBE.

Assignee:

Huntsman International LLC - Austin TX

International Classification:

C07C 4109

US Classification:

568697

Abstract:

A method for the preparation of methyl tertiary butyl ether is provided wherein a mixture of methanol and substantially peroxides-free tertiary butyl alcohol are catalytically reacted to form a reaction product comprising unreacted methanol, unreacted tertiary butyl alcohol, water, isobutylene and methyl tertiary butyl ether, that is separated into a substantially anhydrous first lighter distillation fraction comprising isobutylene, methanol and methyl tertiary butyl ether and a second heavier distillation fraction comprising methanol, tertiary butyl alcohol and water, and wherein the isobutylene and methanol in the first distillation fraction are reacted to form an isobutylene conversion product that contains additional methyl tertiary butyl ether that is substantially free from tertiary butyl alcohol.

Assignee:

Texaco Chemical Company - White Plains NY

International Classification:

C07C 4106
C07C 4109
C07C 4134

US Classification:

568697

Abstract:

An isobutylene feed mixture comprising MTBE, isobutylene and methanol is passed through an isobutylene conversion zone to form an isobutylene conversion product comprising unreacted methanol, unreacted isobutylene, dimethyl ether, MTBE and water, then charged to a countercurrent methanol extraction zone and contacting with water to provide an overhead raffinate comprising isobutylene, MTBE and water, and an extract comprising methanol, water, MTBE, isobutylene and dimethyl ether; the extract is distilled to provide a vaporized overhead fraction comprising MTBE, isobutylene, methanol, and dimethyl ether; the vaporized overhead fraction is partially condensed and from about 5 to 10 wt. % of the mixed phase condensate is vented to thereby provide a liquid condensate that is substantially free from dissolved dimethyl ether, and the condensate is recycled to the methanol extraction zone.

A feedstock mixture comprising methanol and tertiary butyl alcohol in a molar ratio of 2 to 3 moles of methanol per mole of tertiary butyl alcohol is reacted in a first etherification reaction zone at a liquid hourly space velocity of 1 to 10 volumes of feedstock mixture per volume of catalyst per hour. A first reaction product mixture is fractionated to remove MTBE as an overhead fraction. The bottoms fraction comprising unreacted methanol and tertiary butyl alcohol is passed to a second etherification reaction zone at a liquid hourly space velocity of 0. 5 to 4. A second reaction product mixture is fractionated to recover additional MTBE.

Assignee:

Bechtel Corporation - Houston TX

International Classification:

C10B 2118
B01D 314
C10G 914

US Classification:

201 29

Abstract:

An improved coker fractionator system which permits withdrawing, from selected ports in the fractionator, streams of selected boiling point ranges for recovery of thermal energy and for altering the liquid vapor loading within the column for more efficient fractionation within the column. The system includes the provision of one or more ports in a fractionation column between the light coker gas oil draw and the heavy coker gas oil draw connected to either a thermal energy recovery pump-around system or a recycle system for returning a stream to the coker furnace feed stream.
