PSA
The PSA (Pressure Swing Adsorption) process is based on the physical adsorption properties of specially treated molecular sieves. PSA units only need clean, dry air in order to generate N2 cost-effectively and with purities of up to 99.9% (nitrogen). This air is compressed up to 10 bar, purified and then passed through vessels filled with the carbon molecular sieves (CMS). A continuous nitrogensupply is achieved by switching the gas stream: while one vessel is in operation, the other is regenerated by reducing the pressure. The unwanted gas components are released into the atmosphere.
The plant layout is based on the Messer safety and reliability philosophy which has been applied for over 20 years in operating air separation plants for the supply of customers world-wide.
The nitrogen generator has been designed for the ease of operation (under normal conditions) and low maintenance. In order to minimize personnel and operating costs, all equipment and process controls will be operated and monitored by a computer control system.
The plant will be designed according to the latest international rules and regulations.
