CS-16 Calculating Liquid Level in Horizontal Shellside Condensers

2012

HTRI’s current method for calculating the liquid level in a horizontal shellside condenser predicts unreasonable variations, particularly in the gravity-controlled regime. This report presents an improved gravity drainage model that features a smooth transition between the shear- and gravity-controlled regimes. The proposed method can increase or decrease the condensate slope in the gravity-controlled regime so that the calculated variations in the liquid level are reasonable.
