Tozalangan mahsulot tarkibi
Hisoblash. Asosiy ishlab chiqarishning moddiy va issiqlik balanslari. Yillik 2 mlrd m³
Absorberning moddiy balansi
Ushbu hisob kitoblar uchun tabiy gazimiz va tozalangan gazimiz tarkibini bilishimiz muhum hisoblanadi. Shuningdek zavodning yillik unumdorligi kerak bo’ladi
Biz 1soatlik gaz sarfini aniqlaymiz m³/h
V_h=V_y/(24∙335)
Bu yerda V_h –soatlik sarf, V_y –yillik sarf , 24-bir sutkadagi ish vaqti h, 335- bir yildagi ish kuni
V_h=V_y/(24∙335)=2000000000/(24∙335)=250000 m³/h
1.Endi kiruvchi gaz tarkibidagi komponentlar miqdori va hajmiy oqim tezligini aniqlaymiz.
V_i= V_h∙n_i
V_i –gaz aralashmasidagi komponent hajmi m³/h. n_i –komponentning gazdagi ulushi
