Abstract

The article shows the difference between the present and previous requirements of safety regulations in the field of level control in spherical tanks for storage of liquefied hydrocarbon gases and flammable liquids. The description of two of the most currently used methods of level control is given, their advantages and disadvantages are presented. The design features of the structure of spherical tanks, methods of joining them to the level control sensors are described. The dependence of the density change of the liquid product on the temperature change is shown. The changes in the ambient temperature associated with sharply continental climatic conditions of geographical location of the West Surgut field are described. The article demonstrates the complexity of monitoring the temperature and density of the working fluid in the heat exchange between the liquid and the environment due to the initial temperature differences between them. The quality assessment of level measurement and calculation of product density change in spherical tanks using two methods of level measurement is given. In addition, the method of recalculating the readings of the two principles of level measurement is shown, which makes possible to calculate the density of the liquid, to monitor changes in density, without data on the current values of the liquid temperature.
