Jasim, Ali Abdul-Rahman	تأثير اضافة الكحولات وسرعة الغاز على زمن احتجاز الغاز ومعامل انتقال الكتلة في العمود الفقاعي ذو الانبوب الداخلي	2009	10	.pdf	application/pdf	3393	180	67	The liquid phase flow pattern in bubble column was qualitatively described by Kawagoe K, (1976) and by Schumpe A, and Grund, G.R. (1986), who identified the existence of two streams in the column: one heading upwards driven by the buoyancy of gas bubbles and the other carrying the liquid down. The study includes the effect of gas velocity and the addition of alcohols on gas hold-up and mass transfer coefficient in bubble column with draught tube when the length of the column is 1.5m and the ratio of the draught tube diameter to the column diameter equals 0.5 and the air dispersion into the base of the draught tube using a multi hole tuyere is equivalent to a diameter of 0.15 mm and has a free sectional distributor area of 61%.	cache/alkej-555.pdf	txt/alkej-555.txt
