Mass transfer in two‐phase flow in horizontal pipelines

Abstract

Abstract The objective of the present study was to obtain data on the rate of liquid‐phase controlled mass transfer in two‐phase gas‐liquid flow in horizontal pipes. Studies were made on the effect of the mean gas and liquid flow rate, pipe diameter, and pipe orientation on k 𝓁 a , the mean liquid‐phase film mass transfer coefficient. Experimental studies were made on 1 and 4 in. I.D. horizontal pipelines; on 4 in. I.D. 180 deg. vertical short radius bend ( H / D = 2); and on 3/16, 5/16, and 7/16 in I.D. tubes wound in 4‐in. diameter spirals (upflow). A general correlation is presented for k 𝓁 a as a function of the two‐phase frictional energy dissipation, liquid‐phase physical properties, and pipe diameter.
