Method and device for calculating inventory and available capacity in chemical enterprises

Abstract

The invention relates to a method suitable for calculating the stock and capacity of materials in a chemical industry. The method comprises: a table initializing step, a real-time data acquiring step, an inquiry and determining step, a data table inquiring step, a storage tank stock calculating step, a tank region stock calculating step and a result displaying step. The invention further provides a device suitable for calculating the stock and capacity of the materials in the chemical industry. The device comprises a table initializing module, a storage tank template establishing module, a real-time data acquiring module, an inquiry and determining module, a data table inquiring module, a storage tank stock calculating module, a tank region stock calculating module and a result displaying module. With the adoption of the method and the device, liquid level information of a storage tank of the chemical industry, and the corresponding tank stock and capacity can be accurately calculated and displayed in real time; and accurate data are provided for helping the chemical industry to formulate a purchasing plan of the raw material and a finished-product sales strategy, so that the efficiency and precision are improved; meanwhile, the statistical work amount is reduced and the intensity is alleviated.

Description

technical field [0001] The invention relates to the fields of chemical industry, metallurgy, manufacturing and the like, in particular to a method and device suitable for calculating material inventory and capacity in chemical enterprises. Background technique [0002] For a long time, it has been a very cumbersome and difficult task to check the inventory and capacity of raw materials and finished products in tank farms of chemical enterprises, especially when the density of materials changes with temperature, such as propylene, toluene, etc., the specific workflow It is summarized as follows: the inventory personnel go to the tank area to check the temperature, pressure, liquid level and other data in the tank, and record them; according to the recorded results, by querying the propylene temperature-density comparison table, the density of the material at the specified temperature is obtained, and then use the formula Calculate the tank inventory of the material in the sto...

AI Technical Summary

Problems solved by technology

The method of manually recording the temperature, pressure, liquid level and other data in the storage tank and then querying the corresponding table to obtain the key data required for inventory inventory seriously affects the accuracy and timeliness of the calculation results; the current technology also uses fixed density values The method of automatically calculating the stock of materials in storage tanks, but for materials with characteristics of density changing with temperature, the error caused by this calculation method cannot be accepted by the financial system of the enterprise, so it cannot be applied to the actual situation of chemical enterprises In production and operation
