Development of automated balance flow-sheets in refinery commodity and feedstock depots

Abstract

Objective. Development of automated balance flow-sheets in commodity and feedstock depots. Methods. Methods for modelling balance flow-sheets of commodity and feedstock depots, taking into account petroleum products movement and shipping plans, were applied. Results. Examples of automated balance flow-sheets of commodity and feedstock depots specific to refineries are given with the description of technological processes or oil product shipment processes. Rail, road, water, and pipelines shipment automation processes are shown. Operational and daily summaries of balance objects, such as a tank or a group of tanks (commodity group), are graphically shown. An example of an automated dispatch sheet formed on the basis of corresponding automated balance flow-sheets is given. Conclusion. The implementation of automated flow-sheets for all significant production facilities at a refinery, in particular for commodity and feedstock depots, will ensure the visibility and transparency of information on balance objects, which is subsequently used to close a balance sheet for the enterprise as a whole.
