The resource shortage and environment pollution are more and more severe. The industrial structure adjustment and the energy saving of heat exchangers play an important role in petrochemical industry. Recently, Shaanxi Zhituo has developed the a PCHE prototype for petrochemical industry. This PCHE has the advantages of high working temperature and pressure, small volume and weight, and high Heat transfer coefficient. The production efficiency is increased and the cost is lowered to maximize economic and social benefits by applying the PCHE.
