Capacities range from a few hundred Nm³/h to large scale plants with more than 400,000 Nm³/h. The hydrogen product meets every purity requirement up to 99.9999 mol-% and is achieved at highest recovery rates.
Main hydrogen consumers are refineries requiring this valuable gas for example for their hydrocracking, dearomatization or desulphurization processes. As a second group of users in the petrochemical industry has a demand for hydrogen for its methanol and ammonia synthesis, MTBE processes, etc.
The Linde high performance PSA units provide remarkable advantages such as:
Quality: The severe requirements of the PSA process require a selection of special proven plant components (e.g. switching valves and related instruments).
Reliability: The use of selected and suitable plant components implies the high reliability of Linde‘s PSA systems. All components have been tested and approved for suitability in PSA service by Linde.
Availability: The Linde PSA systems are characterized by an outstanding availability of hydrogen supply. With its special features such as operation with reduced number of adsorbers, adsorber group isolation and redundant control system, Linde‘s PSA units achieve virtually 100% on-stream performance and availability.
Flexibility: Excellent flexibility to match actual client‘s needs are achieved with Linde‘s PSA systems as they are capable of providing a high degree of flexibility to cope with feed gas conditions and varying hydrogen demand.
Modular design and prefabricated equipment: Linde‘s high performance PSA systems are prefabricated to a maximum extent. The valve skids containing switching and control valves, instrumentation and interconnecting piping are completely prefabricated, preassembled and tested prior to delivery. This design philosophy reduces time and costs for erection and commissioning on site to and absolute minimum.
Easy maintenance: Maintenance is limited routine actions which can be carried out by the operators on site. Highest attention is given to a proper accessibility of all valves and instruments inside the valve skid. Assistance from Linde is hence normally not required, but is certainly available at any time.
