PREDICTION TECHNIQUE UPDATE FOR PETROLEUM PRODUCTS LOSSES DUE TO TANK «MINOR BREATHING»

Abstract

Background Reducing the loss of oil products from evaporation is a very urgent task. Therefore, this problem continues to be the focus of attention of researchers. In the process of long-term low innage storage of petroleum products in tanks, excessive losses are often caused by «minor breathing». In addition, the total annual «minor breathing» losses of petroleum products from tanks with a capacity of up to 1000 m3 at a low turnover rate (less than 5) may exceed the total annual “major breathing” losses. This is due to the fact that losses associated with tank gas space temperature changes occur every day, and when tank filling - occasionally. Therefore, a proper assessment of petroleum product losses due to tank «minor breathing» is highly relevant. Aims and Objectives The purpose of this article is to update the methodology for predicting petroleum product losses caused by tank «minor breathing». Results An updated technique for predicting petroleum product losses caused by tank «minor breathing» is proposed, including: - an improved formula for estimating the value of losses; - a refined calculation technique for hydrocarbon concentrations and tank gas space temperature during the day.
