How has Adsorption benefited industry?
Over the years, advancements in the field have resulted in substantial cost benefits from and expanded usage of adsorption in a number of industrial settings. One prominent example is in refineries and petrochemical plants where pressure swing adsorption (PSA) has replaced cryogenic distillation as the most economical method for separating hydrogen from various compounds used in these settings. By replacing cryogenic distillation with PSA, refineries and petrochemical plants have been able to reduce costs by anywhere from 60% – 90%. Another example of the cost benefits of adsorption is ARI’s recent development of the Sulfur Dioxide Recovery System (SDRS). In this instance, the SDRS uses PSA techniques pioneered by ARI to enable foundry operators to recover and reuse more than 98% of the sulfur dioxide used in forming cold box molds for metalcasting. According to ARI’s estimates, a mid-size foundry running three shifts a day can expect to save up to 40% of their annual cost of SO2 by us
