    摘要: The present invention relates to a process for treating polyolefin granules in a treatment vessel comprising the steps of: —Providing a bed of granules in liquid in said treatment vessel —Withdrawing a first stream of liquid from said treatment vessel, wherein said first stream of liquid contains hydrocarboneous compounds —introducing a first stream of vapor into said treatment vessel —Withdrawing a second stream of vapor from said treatment vessel wherein said second stream of vapor contains volatile hydrocarboneous compounds —Recovering the granules from said treatment vessel wherein said first stream of vapor has a temperature from Tb to Tb+10° C., wherein Tb is the boiling point of the liquid at the applied pressure, and said first stream of vapor produces an upwards rising vapor stream in said treatment vessel, the superficial vapor velocity of which is no more than 0.2 m/s, and a plant suitable for conducting said process.

    摘要: A Salinity Gradient Solar Pond (SGSP) has saturated salt water in the bottom zone of the pond and nearly fresh water at the top zone, with a gradient zone between the top and bottom. Due to this salinity stratification the upward diffusion of salt is a natural consequence in SGSP's. Controlling the salinity gradient in SGSP systems is vital to their reliable operation. The method for controlling the salinity gradient disclosed in this application, coined the “Pond Rolling Method” by the authors, rapidly drains the pond's non-gradient zones, refurbishes the gradient, and restores the non-gradient zones of the SGSP system, in a manner that minimizes land use, water and heat loss. The salt in the pond is allowed to diffuse upward over time and, on condition as needed to restore the gradient, the Pond Rolling Method is used to completely rebuild the gradient and the SGSP zones.
