Digitalization of Oil Refining Process (Fuel Gas Flow Rate for Hydrotreatment)

Oil refining processes require large quantities of fuel gas. For rational consumption of fuel gas, digitalization of fuel gas consumption is required. The object of the study is the hydrotreating process. The subject of the study is digitalization of fuel gas consumption during hydrotreating. Main research methods: analysis, comparison, econometrics methods. The authors considered the process of hydrotreating diesel fuel. The authors applied reliable statistics from the refinery. Box-Jenkins methods were applied to the obtained time series of specific fuel gas consumption to construct a forecast model of fuel gas consumption during hydrotreatment. The obtained fuel gas flow model will allow predicting the fuel gas flow rate depending on the planned load of the hydrotreating unit. Fuel gas flow control will reduce the cost and price of diesel fuel. Accordingly, reducing the transport component will reduce the prices of goods for which transportation is needed. The further direction of the study is to draw up forecast models for fuel gas consumption at other plants of the enterprise.
