Based on the material of EPDM, we develop specialized rubber material for low-temperature multi-effect distillation (LT-MED) conditions. For heat transfer tube and tube sheet connected to the rubber (herein referred as EPDM rubber material) ring are used in the LT-MED desalination equipment, we make regular aging and multivariate synergistic aging test on EPDM. According to the experimental results, we develop an evaluation method applicable to usage of sealing rubber material under LT-MED conditions, and rubber material properties are measured by the changes of mechanical indicators. Finally, we also tested the sealing performance of the sealing rings. The results show that EPDM rubber material can tolerate the LT-MED conditions with the ring boost rate of 0.038kPa/h when the rates of change in Shoer hardness range from-5% to 10%, the rates of change in tensile strength within-20%, the rates of change in elongation at break range from-30% to 10%.

Abstract In order to explore a more reasonable structure and operating parameter, guide the design and improve the gasification of seawater Open Rack Vaporizer (ORV), Research on the rules of seawater that flows and heat transfer in the ORV tube was studied in this paper. By simplifying the model, heat transfer tube model with spoiler lever was obtained and simulated, the distribution of temperature field, gas ratio, velocity field and press field in rib tube were analyzed, and different inlet velocity of LNG, roughness of the tube wall both effected on the overall gasification, the results shows that the actual gasification efficiency from heat transfer tube is higher than normal, small difference of gas ratio outlet, velocity and temperature are both lower, LNG could be easer gasified at operating temperature between -162°C~+3°C than that between -162°C~+0°C.
