摘要： A process for removing substantial quantities of volatile liquid e.g. hydrocarbon from a mixture of polymer and such liquid is provided. This process consists of the initial step of introducing the mixture, and a liquid which is immiscible with the polymer, into a mixing/kneading zone provided with heated heat transfer surfaces having a temperature higher than the boiling point of the lowest boiling liquid component in the mixing/kneading zone. The mixture and the immiscible liquid are subjected to a period of continuous mixing and kneading within the mixing/kneading zone, to bring the mixture into continuously moving contact with the heat transfer surfaces. During this period of continuous mixing/kneading, the heated heat transfer surfaces are repeatedly mechanically cleaned to prevent buildup of solid polymer thereon. Volatilized liquid is vented from the mixing/kneading zone during the period of continuous mixing and kneading, and the polymer and residual liquid is subsequently discharged from the mixing/kneading zone.
摘要翻译：一种除去大量挥发性液体的方法，例如提供了来自聚合物和这种液体的混合物的烃。该方法包括将混合物和与聚合物不混溶的液体引入混合/捏合区域的初始步骤，所述混合/捏合区域设置有温度高于沸点的最低沸点液体组分的沸点的加热的传热表面混合/捏合区。将混合物和不混溶液体在混合/捏合区域内进行连续混合和捏合的时间，使混合物与传热表面连续移动接触。在连续混合/捏合期间，加热的传热表面被反复机械地清洁，以防止固体聚合物在其上积聚。在连续混炼和捏合期间，从混合/捏合区排出挥发液，然后将聚合物和残留液从混合/捏合区排出。
