In petroleum exporting countries, exhaust gas from crude oil tanker through loading operation at offshore terminals is the serious pollutant. A spray absorber, which is not affected by pitching and rolling motions in a floating plant, will be key equipment for the vapor recovery from crude oil ship loading. Because there was no case to apply crude oil sprays for vapor recovery, a series of pilot tests had been conducted to confirm the performance of spray absorber. Crude oil vapor is very complex in nature and it makes the analysis of the pilot test result quite difficult. By focusing on butane, the performance evaluation was easily performed and the possibility to apply the spray absorber was suggested. A simplified model was proposed to trace the phenomena in the absorber, and it was proved that the performance could be simulated by the calculations based on the model.
