General information
FCPSA plants use two technological accomplishments: the two-valve rotary system and the new-generation structured adsorbent stable to fluidization. This ensures an up to 100-time increase in the cycle speed — up to 50 cycles per minute — as compared with conventional PSA plants and, as a result, a multiple reduction in the required volume of adsorbent. This is why, the dimensions and weight of FCPSA plants offered by Grasys are by an order of magnitude lower than those of conventional PSA plants.
In contrast to modern FCPSA plants all conventional PSA plants so far have used only granular adsorbent. Due to possible loss of such adsorbent, the cycle speed may not be materially increased and varies within 0.05 to 0.5 cycles per minute. In order to provide the required capacity, PSA plants include 4 to 16 large-scale adsorbent beds with a complex system of valves and pipelines. FCPSA plants offered by Grasys have no such deficiencies and are increasingly gaining popularity all over the world.
