Handley’s latest innovations include the following patents:

1. **Integrated Nitrogen Liquefier for a Nitrogen and Argon Producing Cryogenic Air Separation Unit**

This invention provides a nitrogen liquefier that integrates seamlessly with an argon and nitrogen producing cryogenic air separation unit. It features a method of nitrogen liquefaction that operates in three distinct modes: nil liquid nitrogen mode, low liquid nitrogen mode, and high liquid nitrogen mode. The system is characterized by the use of an oxygen-enriched stream from the lower pressure column of the air separation unit, which serves as a condensing medium for the argon condenser.

2. **Air Separation Unit and Method for Production of Nitrogen and Argon Using a Distillation Column System with an Intermediate Pressure Kettle Column**

This patent presents an air separation unit designed for cryogenic distillation to separate air effectively. The system includes a higher pressure column, a lower pressure column, an intermediate pressure kettle column, and an argon column arrangement. It is particularly effective for producing argon and several nitrogen products, employing a once-through kettle column reboiler and condenser for enhanced operational efficiency.
