["본 게시글은 reelove가 2-21-1-11-11:18까지 편집했습니다. 가연화反应器反应器尺寸的设计，我们用油品的体积流量Q除以空速SV催化剂的装填量，然后留出瓷球、保护剂和其他设备空间，得出反应器的总体积V. 现在想问下大家在计算Q的时候，密度选择操作工况下的值还是常温下的值，谢谢！"

"주로要看空速测定条件，尽管空速单位是时间的倒数，但实际是介质体积流量除以催化剂体积，故要看这个体积流量是什么。在气固相反应中更明显，一般气固相的空速都是以标准状况计的。所以这个数要与催化剂厂家落实。"

"이를 결정하는 데는 공速是怎样定义的很重要。常用的空速有两种状态，一种是标态，一种是反应器入口状态。空速数据指的是哪种状态的，那你的体积流量就对应取同一状态"
