Pressure Swing Adsorption

With the HP process, gases with a considerable content of hydrogen are purified into high purity hydrogen by pressure swing adsorption (PSA). The HP process is designed for hydrogen production at highest efficiency from various raw gases within different industries, eg. refining, (petro)chemical, oil and food, fatty acids or steel-making.

Within Caloric HP process the PSA can be designed either with 4, 5 or 6 adsorber vessels, depending on customer requirements and their focus on optimisation for process efficiency, on-stream time, investment and operational costs.

The PSA will be designed according to Caloric's well established skid mounted, modular design (Design-Concept). The PSA will be pre-manufactured in Caloric's workshop and tested before delivery. Such design and manufacturing approach will secure shortest re-erection at site and savings in reduced time and costs required on-site to put the plant into operation, compared to "loose item" delivery.
