利用aspenplus進(jìn)行物性參數(shù)的估算講解

1、1純組分物性常數(shù)的估算1.1、乙基2-乙氧基乙醇物性的輸入由于Aspen Plus軟件自帶的物性數(shù)據(jù)庫中很難查乙基 2-乙氧基乙醇的物性參數(shù), 使模擬分離、確定工藝條件的過程中遇到困難，所以采用物性估算的功能對乙基 2-乙氧 基乙醇計(jì)算。已知：最簡式：（C6H4O）分子式：（CHCH-O-CH-CH-O-CH-CH-OH）沸點(diǎn)：195C1.2、具體模擬計(jì)算過程乙基2-乙氧基乙醇為非庫組分，其臨界溫度、臨界壓力、臨界體積和臨界壓縮因子 及理想狀態(tài)的標(biāo)準(zhǔn)吉布斯自由能、標(biāo)準(zhǔn)吉生成熱、蒸汽壓、偏心因子等一些參數(shù)都很難 查詢到，根據(jù)的已知標(biāo)準(zhǔn)沸點(diǎn) TB,可以使用aspen plus軟件的Estimati

2、on In put Pure Component（估計(jì)輸入純組分）對純組分物性的這些參數(shù)進(jìn)行估計(jì)。為估計(jì)純組分物性參數(shù)，則需1. 在Data （數(shù)據(jù)）菜單中選擇Properties（性質(zhì)）2. 在Data Browser Menu（數(shù)據(jù)瀏覽菜單）左屏選擇 Estimation（估計(jì)）然后選 Input（輸入）3. 在 Setup（設(shè)置）表中選擇 Estimation（估計(jì)）選項(xiàng)，Identifying Parameters to be Estimated（識別估計(jì)參數(shù)）4. 單擊Pure Component（純組分）頁5. 在Pure Component頁中選擇要用Parameter（參數(shù)）列

3、表框估計(jì)的參數(shù)6. 在Component（組分）列表框中選擇要估計(jì)所選物性的組分如果要為多組分估計(jì)選擇物性可單獨(dú)選擇附加組分或選擇 All（所有）估計(jì)所有組分的物性7. 在每個組分的Method（方法）列表框中選擇要使用的估計(jì)方法可以規(guī)定一個以上 的方法。具體操作過程如下：1打開一個新的運(yùn)行，點(diǎn)擊Date/Setup母 Special ions|aT 71 oll N*|iet990口豈co 豈1ira-fr“ Q EL fflSpecificationsSimulation OptionsStream ClassSubstreamsUnits-SetsCustom UnitsReport O
