Benefits of technology

This patent describes methods and systems for combining multiple product trains into a single facility. This would allow producers to quickly adjust to changes in demand for each product and reduce the need for transporting certain production intermediates, which can be dangerous and reactive. The technical effect of this patent is to streamline production processes and improve efficiency while also improving safety.

Problems solved by technology

Industrial-scale production of most chemicals generally relies upon devoted synthetic precursors, chemical transformations and production plants that cannot easily accommodate or integrate the production of other chemicals.

Abstract

Disclosed are integrated systems and methods for the conversion of epoxides to beta lactones and to multiple C3 products and / or C4 products.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Patent Application No. 62 / 116,234, filed Feb. 13, 2015, which is incorporated herein by reference in its entirety.FIELD[0002]The present disclosure relates generally to the production of chemicals, and more specifically to the conversion of epoxides to various C3 products and / or C4 products, such as acrylic acid and acid anhydrides.BACKGROUND[0003]Industrial-scale production of most chemicals generally relies upon devoted synthetic precursors, chemical transformations and production plants that cannot easily accommodate or integrate the production of other chemicals. For example, production of three-carbon-containing C3 chemicals, such as acrylic acid (AA) and esters thereof, and that of four-carbon-containing C4 chemicals, such as succinic anhydride (SA), generally proceed from distinct precursors via unrelated transformations that require specialized plants and methods.[0004]Acrylic a...
