The present invention provides, among other things, new processes for separating and purifying C4 fractions from a crude C4 stream. Compared to prior methods, the processes of the present invention simplify the C4 separation processes, afford more possible configurations for separation and purification, and are more cost effective. The processes and systems provided herein can be used as part of a cost-effective and efficient method for synthesizing methyl tertiary-butyl ether.

Methods and systems for separating C4 crude streams

The present disclosure relates to a method for purifying an acid, wherein the method comprises: a) producing a crude product mixture by a partial oxidation reaction, wherein the crude product mixture comprises acrylic acid and acetic acid; b) purifying the crude product mixture by distillation using a high-boiling solvent to purify the acrylic acid; and c) purifying the crude product mixture by distillation using a low-boiling solvent to purify the acetic acid.

Method for the purification of acetic acid and acrylic acid

A reactor and process for removing unsaturated alkynes and diolefinic impurities from olefins and oxygenates.

Hydrogenation reactor and process

Mixed alcohols are produced from syngas. The syngas is provided to a catalyst in a reactor at selected temperatures and pressures. Reactive products, including mixed alcohols, are removed from the reactor. Non-reactive components are removed from the mixed alcohols of their reaction products. At least part of the non-reactive components are reintroduced in the reactor along with syngas. The non-reactive components are a solvent or a supercritical fluid. The nonreactive components can be reintroduced into the reactor with reactive components such as methanol or CO.
