fruit juice at 25 ° C containing 5% total solids concentrated via a single effect evaporator. The evaporator is operated in a vacuum at an evaporation temperature of 80 ° C, and 90% quality steam is supplied at 169.06 kPa. The desired concentration of the final product is 40% total solids. The rate of concentrated product leaving the evaporator is 2500 kg / hour. The specific heat of fruit juice is 4.05 kJ / (kg ° C), and the concentrated product is 3,175 kJ / (kg ° C). Calculate the required steam rate and Steam economy if the condensate temperature is released at 90 ° C

Question
fruit juice at 25 ° C containing 5% total solids concentrated via a single effect evaporator. The evaporator is operated in a vacuum at an evaporation temperature of 80 ° C, and 90% quality steam is supplied at 169.06 kPa. The desired concentration of the final product is 40% total solids. The rate of concentrated product leaving the evaporator is 2500 kg / hour. The specific heat of fruit juice is 4.05 kJ / (kg ° C), and the concentrated product is 3,175 kJ / (kg ° C). Calculate the required steam rate and Steam economy if the condensate temperature is released at 90 ° C

Transcribed Image Text:Jus buah pada 25 °C mengandung total padatan 5% dipekatkan melalui evaporator efek tunggal. Evaporator
dioperasikan secara vakum pada suhu evaporasi 80 °C, dan uap dengan kualitas 90% dipasok pada 169.06 kPa.
Konsentrasi yang diinginkan dari produk akhir adalah 40% padatan total. Laju produk pekat yang keluar dari
evaporator adalah 2500 kg/jam. Panas jenis jus buah adalah 4.05 kJ/(kg °C), dan produk pekat 3.175 kJ/(kg
°C). Hitung
a. Laju uap yang dibutuhkan adalah sebesar =
kg/jam.
b. Keekonomian uap (Steam economy) jika suhu kondensat dilepaskan pada 90 °C. =
(kg air
menguap/kg steam)
