Membrane Purification

Membrane Purification

With the HPM process, gases with a considerable content of valuable gas are purified by using highly selective membranes. The HPM process is designed for gas 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 HPM process the membranes can be designed using as many membranes in parallel as required by customers requirement related to gas purity and as many stages as required by customers requirement to the systems gas recovering efficiency. The unit will be designed depending on customer requirements and their focus on optimisation for process efficiency, on-stream time, investment and operational costs.
The membrane unit will be designed according to CALORIC’s well established skid mounted, modular design (design concept). The unit 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.
