PSA Hydrogen Package
For hydrogen recovery/purification applications where the feed stream is at low to intermediate pressure (< 68 barg) and where downstream process requirements require minimum pressure reduction and high purity hydrogen product, Pressure Swing Adsorption (PSA) technology is the process of choice.
We offer PSA unit as modular units, complete with hardware, adsorbents, and controls systems. We do all the engineering, documentation and project management, with fabrication completed by the qualified sub-vendors.
We specialize in fabricating Adsorbers to comply with the ASME Boiler and Pressure Vessel Code, Sect. I, Sect. VIII Div. I.
Fatigue analysis is carried out for all Adsorbers.
The following process parameters influence the design and performance of a PSA unit:
Feed Gas Composition: The PSA process can handle feed gas with a wide variety of impurities including but not limited to water, carbon oxides, methane, nitrogen and hydrocarbons.
Hydrogen Recovery: Recovery is the ratio of the quantity of hydrogen from the feed that is recovered in the product. Recovery is influenced by product purity, feed composition (nature and quantity of impurities) and pressure conditions.
Feed and Tail Gas Pressure: The adsorption pressure can be fixed by either the available feed pressure or the required product pressure.
Product Purity: The product purity requirements influence the recovery, as the difference between 1 or 100 ppm mol. of a controlling impurity (CO, N2, CH4) demands more or less adsorbent utilization during adsorption.
PSA Adsorbents: The zeolites and other adsorbents will be selected from well-known European manufacturers. Adsorbents are suitable to meet the application specific demands and project requirements.
Process Cycle Time: The size of a PSA adsorber is proportional to the amount of impurities to be adsorbed per cycle. PSA adsorber size will increase with increasing impurities flow rate during the adsorption step and decrease with the adsorption time.
PSA Nitrogen Generation Package
Advanced technology nitrogen gas generator for industry leading performance; a source of increased productivity, sustainability and profitability.
The high performance nitrogen adsorption generators are available in various capacities producing nitrogen gas with up to 99.9999% purity. Implementing the most recent technologies, these packages are very energy efficient according to international standards in the oil and gas as well as in the chemical industry.
The nitrogen generation systems continuously produce high purity nitrogen from compressed air and eliminate the inconvenience of a delivered nitrogen supply. A continuous supply of consistent purity is available within minutes of startup.
Installation is very simple and foundation free, pipe in compressed air and pipe out nitrogen. Just connect a standard compressed air line to the inlet of the generator, connect the outlet to your nitrogen line or header and the unit is ready for trouble free operation. The system is designed to operate 24 hours/day, 7 days/week.
An oxygen analyzer monitors to measure the oxygen concentration of the nitrogen stream.
Nitrogen and application
The gaseous nitrogen is inert and makes up 78% (by volume) of the air. It can be used in a wide range of applications.
Oil platform/refineries: Nitrogen can be used for blanketing, purging, inerting of potentially explosive concentrations of oxygen in processes, piping and tank farm storage vessels in oil and gas condensate refineries.
Chemical Processing: Blanketing with gaseous nitrogen, is used to ensure the chemical integrity and maximize safety. Blanketing with gaseous nitrogen controls the oxygen concentration and moisture within the vessel, protecting the product from contamination, degradation, and chemical change. It means the reduced oxygen level minimizes the chance of explosion in chemical processing.
Metal Processing: Using gaseous nitrogen as inert to minimize the contact with oxygen improves final product quality and minimizes rework. Keep the quality and save the money.
Food and Beverage: Using gaseous nitrogen as inert to protect the product against bacterial growth and oxidation, which can compromise product quality and shelf life. Using nitrogen minimizes the levels of oxygen present and significantly improving shelf life.
