Unique corrosion conditions in oil refining processes lead to the necessity of using passive and active protection systems, aimed at preventing from damages and ensuring the correct operating conditions of machines. To prevent from the development of corrosion processes on the internal surfaces of horizontal settlers, sacrificial protection is used. Before installing such a protection, they usually calculate the number of protectors to be installed in parallel. Some inputs are stochastic by their nature, which should be considered in assessing the risk of non-achieving the required protection level. The probabilistic model proposed to calculate the parameters of sacrificial tank protection that allows performing an exploratory design based on considering various environmental aspects to decide on the efficiency of sacrificial protection and to assess the achievement of the required protection level.

AbstractDeacidification is one of the key steps in oil-refining processes. This study reported a simple approach for upgrading high-acid adlay bran oil by supercritical carbon dioxide (SC-CO2) extraction. The high-acid adlay bran oil was obtained by three-stage countercurrent ethanol extraction of adlay bran, with high free fatty acids (34 % FFAs). The FFA content in adlay bran oil reduced to 10.6 % by SC-CO2extraction under optimized conditions. Interestingly, the SC-CO2deacidification process also markedly reduced oil color value from 11.5 (Red) to 0.3 (Red) and acetone-insoluble matters in the oil from 1.56 % to 0.17 %. The results indicated solvent extraction combined with SC-CO2deacidification method could be a feasible approach to significantly upgrade high-acid adlay bran oil and simplify refining process of adlay bran oil.
