Experimental device and experimental method for heat and mass transfer process of floating roof crude oil storage tank

Abstract

The present invention relates to an experimental device for the heat and mass transfer process of a floating roof crude oil storage tank and an experimental method thereof, wherein the experimental device for the heat and mass transfer process of a floating roof crude oil storage tank includes an experimental tank, the experimental tank is a floating roof storage tank, and the experimental tank There is a temperature-controlled water bath interlayer on the outside of the tank wall and floating roof, and a tank wall temperature sensor is installed in the water bath interlayer; there is an electric heating film on the outer wall of the tank bottom, and a temperature sensor is installed on the inner wall of the tank bottom. Both the electric heating film and the temperature sensor are connected to the data acquisition control system The test tube extends into the tank through the test hole of the floating roof, a plurality of thermocouples are packaged in the test tube, the test tube is connected with the data acquisition control system, and the data acquisition control system is connected with the computer; the inner wall of the floating roof, the inner wall of the tank wall, the tank There are multiple heat flow sensors on the inner wall of the bottom, and the heat flow sensors on the tank wall are arranged correspondingly to the thermocouples; the test holes are arranged in sequence along the radial direction, and the test holes correspond to the heat flow sensors on the inner wall of the tank bottom; sampling holes are also arranged on the test tube , the experimental tank is connected to the preheating tank. The invention has rich test data and accurate measurement results.

Description

technical field [0001] The invention relates to experimental research on the heat and mass transfer law of crude oil stored in a floating roof storage tank, sending and receiving oil and putting into production, in particular to an experimental device and an experimental method for the heat and mass transfer process of a floating roof crude oil storage tank. Background technique [0002] In recent years, in order to cope with the world's oil situation, my country has successively carried out the construction of strategic oil reserves and built many large oil reserves. Due to the advantages of low evaporation loss and good economy, floating roof storage tanks have become the preferred storage tank type. In the storage process of crude oil, its temperature change law has always been a concern in production. Knowing the oil temperature distribution and change law of storage tanks under different working conditions is the key to formulating storage tank operation management plan...
