Benzene is a clear, volatile liquid made up of six carbon atoms and six hydrogen atoms arranged in a ring shape. It is an important intermediate chemical that can be commercially used to manufacture many popular end products. The Chemical Design Benzene removal system is designed to remove and recover benzene from HCl, hydrogen and natural gas. It employs an arrangement that allows electric heater size and therefore maximum instantaneous heat demand to be cut in half. This arrangement not only saves the customer energy costs but allows a more continuous return of recovered benzene. A typical HCl purification system is shown here.
