This design uses in lowtemperature series transformation process, and the process of various materials and equipment, material balance can be calculated for selection of equipment. In the selection of equipment for low temperature shift in the main furnace calculated: low shift catalyst dosage, the selection and calculation of furnace temperature transform technology dimensions.Keywords: synthetic ammonia, transform, catalyst, calculation and selection四川理工學(xué)院畢業(yè)設(shè)計(jì)（論文） 目錄 ⅰ 目錄 言.................................................................................................1 工藝原理 .......................................................................................................................................1 變換工藝流程確定 ......................................................................................................................1 變換工藝參數(shù)的確定 ..................................................................................................................2 壓力 .......................................................................................................................................2 溫度 .......................................................................................................................................2 汽氣比 ...................................................................................................................................2 主要設(shè)備的選擇說(shuō)明 .................................................................................................................3.....................................................................4 變換爐物料衡算及熱量衡算 .....................................................................................................4 已知轉(zhuǎn)化氣組成 ..................................................................................................................4 本設(shè)計(jì)的計(jì)算基準(zhǔn) ..............................................................................................................4 工藝條件的確定 ..................................................................................................................4 ............................................................................................4 變換爐催化床層的熱量衡算 .............................................................................................6 變換爐催化劑平衡曲線 .....................................................................................................7 最佳溫度曲線的計(jì)算 ..........................................................................................................8 操作線計(jì)算 ..........................................................................................................................8 ...................................................................10 飽和塔的物料與熱量衡算 ........................................................................................................10．熱水塔物料與熱量衡算 .........................................................................................................12 ...........................................................................................................13 ...............................................................................................................14 ...........................................................................................................15 物料匯總表 .................................................................................................................................17 熱量匯總表 .................................................................................................................................18 ................................................................................................20............................................................................................................................20............................................................................................................................23............................................................................................................................27 ...................................................................................................................30 ...................................................................................................................36 ................................................................................................................................43 ............................................................................................................................................43四川理工學(xué)院畢業(yè)設(shè)計(jì)（論文） 言 ⅱ ............................................................................................................................................44 .............................................................................................................................
