FIELD: control and monitor system for oil product discharge with the use of circulation heating systems, particularly in terminal station of petroleum storage depot.
SUBSTANCE: method involves determining temperature of outer tank car wall by measuring thereof in lower tank car case portion, which is the nearest to tank car bottom; comparing the measured temperature with one estimated from heat calculations performed with the use of control computer. The temperature is calculated from well-known correlations with taking into consideration previously measured temperature of ambient air and wind velocity, technical characteristics of tank cars, physical properties of oil product to be discharged and air.
EFFECT: increased efficiency due to reduced amount of residual oil product and reduced flow rate of heating agent due to determining time point optimal for heater deactivation.
