: Ochilova D.U. Tajribani material balansini tuzish Tajriba yakunlangandan so’ng byuretkadagi xomashyo sahti, gaz soati ko’rsatishi va gaz o’lchagichdagi gaz hajmi qayd etiladi. Yig’gichlar va absorber o’lchanadi, distillyat massasi va uning absorberdagi o’sishi aniqlanadi. Reaktor sovutishdan so’ng tizimdan ajratiladi, qopqoq olinib, hosil bo’lgan barcha koks ehtiyotlik bilan olinadi va uning massasi o’lchanadi. Tajriba material balansini tuzishda gaz o’lchagichdan olingan gaz zichligi aniqlanadi. Tajriba material balansi quyidagi qismlarda tuziladi: Kiritilgan g % Xomashyo ............................................................. 100 Olingan Distillyat................................................................. Koks....................................................................... Absorber massasi ko’payishi............................. Gaz (hajmi x zichlik)........................................... Yo’qotish............................................................... Kokslashda hosil bo’lgan distillyatlar qolonkali kolbada atmosferali va Klyayzen tipidagi kolbada vakuumli haydashdan o’tkaziladi va quyidagilar olinadi: benzin (q.b.-200 ℃), yengil gazoyl (200-350℃), og’ir gazoyl (350- 450 ℃), qoldiq (450℃ dan yuqori). Haydashlar yakunlarini umumlashtirib, yo’qotishlarni hisobga olgan holda jarayonning kengaytirilgan material balansi tuziladi: Kiritilgan g, % Xomashyo................................................................................... 100 Olingan Kokslash benzini 200 ℃ gacha (absorber massasi ko’payishi bilan birgalikda) ................................................................. Engil gazoyl (200-350 ℃)..................................................................... Og’ir gazoyl (350-450 ℃) .................................................................... Qoldiq (450 ℃ dan yuqori)................................................................... Koks..................................................................................................... Gaz....................................................................................................... Yo’qotishlar tajribada.............................................................................................. haydashda........................................................................................... ______________________________________________________________ № hujjat ҳ O`z.
