Appl. No.:

09/949603

Inventors:

Barry Billig - Irvington NY
James Mann - Brooklyn NY

Assignee:

Scientific Design Company, Inc. - Little Ferry NJ

International Classification:

C07D30132

US Classification:

International Classification:

B01D 59/50
C07D 301/32

US Classification:

55321, 549538

Abstract:

In an ethylene oxide process, the stripping and reabsorption operations, normally carried out in separate vessels, are carried out in a single vessel which is divided by a baffle into separate sections where reabsorption and stripping are carried out.

International Classification:

C07D 301/10

US Classification:

549534, 549536

Abstract:

A method to achieve a controlled start-up temperature of an expoxidation process which exceeds the maximum achievable temperature of the epoxidation reactor relative to using an external heat source. The method of the present invention employs an oxidation reaction within the reactor to bring the temperature of the reactor to a temperature that is suitable for conditioning a high selectivity catalyst. The method of the present invention includes first bringing a reactor including a high selectivity catalyst to a first temperature using the external heat source to the reactor, while staying within the reactor design limitations and maintaining a gas flow to the reactor that is within 25 to 100% of the design rates. Once the reactor has achieved the first temperature, at least an olefin, e. g. , ethylene, and then oxygen are introduced to the reactor feed gas.

Abstract:

This invention relates to a process for reducing the corrosion rate of iron-containing vessels within an ethylene glycol distillation system. The inventive process includes the addition of an additive component of sodium nitrite and sodium hypophosphite into such iron-containing vessels, to thereby react with iron of the inside walls and form a protective coating thereon. This process reduces the corrosion rate in iron-containing vessels of the apparatus, and reduces the catalytic effects of iron corrosion products within the system. Thus, not only is the on-stream time of the vessels extended, but also product quality is improved by reducing the aldehyde content of the final ethylene glycol product.
