3.2 Material balans
Material balans
Xomashyo materiallarini va ishlab chiqarish mahsulotlarini material balansini hisoblaymiz. Yiliga 180 000 t polistirol ishlab chiqartishda tayyor xomashyodagi yo‘qotilish-0.5%:
180000----100%
X --- 0.5%
X=180000*0.5/100=900t
X=180000+900=180900t
Qadoqlashdagi yo‘qotilish-3%
180900----100%
X1 --- 3%
X1=180900*3/100=5427t
X1=180900+5427=186327t
Sintez kolonnada-3%
186327----100%
X2 --- 3%
X2=186327*3/100=5589t
X2=186327+5589=191917t
Reaktorda yo‘qotilish – 5%
191917----100%
X3 --- 5%
X3=191917*5/100=9596t X3=191917+9596=201513t
Purkagichda – 4%
201513---100%
X4 --- 4%
X4=201513*4/100=8061t
X4=201513+8061=209574t
Kondensator -3%
X5=209574*3/100=6287t
X5=215861t 27
Xulosa
Menga “Polistirol ishlab chiqarish texnologiyasi ” mavzusi bo`yicha kurs ishi topshirildi. Shu topshiriqni bajarish uchun dastlab adabiyotlardan etilenglikol va xomashyolar haqida, uni qayerlarda ishlatilishi va qanday usulda olinishini o’rganib chiqdim. Kurs ishini ishlash natijasida sintez jarayonlari va texnologik uskunalar, ishlash prinsplarini, hisoblash jarayonlarini o`rgandim.
Material balans hisoblash ishlarini dastlab, tayyor mahsulotning yo’qotilishini hisoblab topishdan boshladim va har bir jarayondagi yo’qotilishlarni hisoblab nazariy tahlil va sanoatdagi ko’p yillik natijalar asosida, har bir jarayondagi xomashyo sarfi miqdorini aniqladim. Bundan tashqari jarayonning issiqlik balansini tuzib hisoblab chiqdim.
