英文
subfractionation-
Definition of the multivariable control strategy has been provided in sufficient detail with emphasis on the regenerator control, cracking conversion control, pressure balance control, main fractionator bottom control and cracking yields control
從燒焦控制、裂化苛刻度控制、壓力平衡控制、分餾塔底控制和裂化產率優化控制等五方面詳細論述了反應-再生系統的控制策略。Then, analytical work was carried out as follows : the ultimate analysis and physi - chemical analysis of the pyrolytic oil comprised a sketch of the fuel properties of the oil ; then, through the distillation analysis of the oil, the fraction composition of the " unrefined " oil was known. after that, a general knowledge of the aromaticity and saturation of the hydrocarbons in the oil was provided by the outcome of the ft - ir functional group analysis. also, from the analysis, the form of the polar functional groups and their distribution in different fractions of the oil were learned
文中首先對不同熱解溫度下熱解油產率進行分析討論，然後，針對熱解油品質進行了一系列分析：通過元素組成和理化特性的分析，對熱解油作為燃料特性有了一個大致了解；通過實沸點蒸餾分析，得到熱解油作為一種未提煉油的餾分分佈，並為后續熱解油餾分的細入分析提供了前提；通過對熱解全油和各窄餾分的ft - ir官能團分析，對熱解油的芳香性、不飽和性有了整體的了解，並且清楚了熱解油中的極性官能團存在型式及其在熱解油不同餾分中的分佈。Then, the oil fractions from distillation were further studied
之後，對熱解油按不同餾分進行了更細入的分析。The design model of seawater desalination with the tvc falling - film evaporation process was deduced. the transfer coefficient of falling - film evaporation process was analyzed in detail. and the effect of the parameter change of process steam to the operation of the device was calculated and discussed
本文主要開展tvc壓縮蒸餾海水淡化技術研究，建立了tvc壓縮噴淋降膜蒸餾海水淡化裝置的設計模型，對降膜蒸發過程的傳熱系數進行了詳細的分析，並對工作蒸汽參數變化對裝置運行的影響進行了分析計算。分享友人
