C09K 3/00

US Classification:

560241, 252372

Abstract:

The present invention provides an integrated, optimized process for the production of ethylene, carbon monoxide and acetic acid from an ethane feed, including reacting ethane with oxygen in the presence of a catalyst to produce ethylene, carbon monoxide and acetic acid in a reactor, wherein the catalyst comprises the elements Mo, Pd, X, and Y in the gram-atomic ratios MOPdXY, and the oxygen partial pressure in the reactor is about 15 psia to about 50 psia. The partial pressure of ethane in the reactor is about 50 psia to about 150 psia.

C10G 2/00

Abstract:

Disclosed herein is a modular process plant structural system which includes numerous modules, all ISO-certified under ISO 1496 and capable of holding within the entire module at least one chemical (or non-chemical) production plant piece of equipment, capable of individually being shipped or transported. The modules can be stacked vertically, horizontally, or mixed (both vertical and horizontal arrangement). The modules are pre-fabricated offsite, built with the desired equipment within the module, pre-plumbed with piping, instrumentation, and electrical wiring, and then the multiple modules are shipped multimodally as ISO 1496 containers to the desired location and assembled to form a plant. Generally, two or more modules are connected together to form a complete plant. The plant can be of any type, e.g., chemical, mechanical/production, thermal, and the like, or of any size, e.g., production, small, micro, or pilot plant scale. When no longer needed, the plant may be disassembled and reused at another site or facility.
