该怎么翻译好呢?工艺设计程序相关? 工艺设计中首先确定工艺流程方案,根据原料基础数据和生产任务确定塔板数和各阶段的工艺参数和原料物性参数,然后根据这些参数确定塔径和塔板的工艺尺寸并完成塔板的流体力学验算和负荷性能图的绘制。 when you design a process, process flow diagram should be fixed first. process conditions at different units and number of trays in the column/tower are determined by physical properties of the raw meterials fed into the column/tower. with these parameters, you can then determine the diameter of the column/tower and dimensions of the tray. calculations regarding the fluid dynamics of the process flow are thus performed. and 负荷性能图 should also be prepared. 负荷性能图是什么?是utility flow diagram么?查看更多
