Latest Patents

Sophia's latest patents include an **Air Separation System and Method** and an **Air Separation Apparatus**. The Air Separation System details a process for separating air within an air separation plant, focusing on diverting a portion of the compressed, purified air stream. The system is designed to selectively produce either a higher pressure or lower pressure compressed output stream. This innovative approach involves cooling these streams in a main heat exchanger through indirect heat transfer with various product streams from the plant. Furthermore, a secondary portion of the air stream is partially cooled and expanded in a turbo-expander to yield power and an exhaust stream, which contributes additional refrigeration to the distillation column system.

The Air Separation Apparatus provides a method for adjusting production rates of liquid products between high and low levels by manipulating the pressure ratio across a turbo-expander. This invention incorporates a branched flow path equipped with a system of valves that manage the introduction of a refrigerant air stream to either a booster compressor branch or a bypass branch, offering flexibility in operational modes and ensuring continued efficiency during production transitions.
