Petrochemical plants process hydrocarbon and olefin base feed streams that must go through extensive treatment to produce a variation of products. Hengye’s adsorbents are designed to help remove necessary material to meet required specifications. Impurities that are commonly removed in these streams can range from oxygenates, sulfur compounds, water, and others.
