Digital Sulfuric acid APP

System Introduction

Background

The chemical industry is by far the largest oil and gas industry, consuming 13 million barrels of oil and 305 billion cubic meters of gas per day. By 2050, global demand for chemicals will be 50% higher than in 2020, and even under a net-zero emissions scenario, the International Energy Agency (IEA) believes that oil will continue to be the primary feedstock for the production of chemicals. Then sulfuric acid, as a basic chemical raw material, also occupies an important position in the chemical industry. It is estimated that 65 million tons of sulfur are produced globally each year, while 250 million tons of sulfuric acid are consumed globally each year for the production of energy and health-related products. Since sulfur resources are non-renewable, the annual shortage of 17 million tons of sulfur requires the extraction of sulfur resources from other sulfides. The popularity of new energy sources and the continuous growth of the population have made the utilization of sulfuric acid resources and the goal of achieving net zero emissions a complex dual challenge. In order to make the sulfuric acid industry healthy and sustainable development, Lilly is redefining the sulfuric acid production and management methods, namely digital transformation.

Target User

Software Main Function

Digital sulfuric acid provides users with parameter query, digital sulfuric acid information, material balance, process training, consulting services and other functions. The parameter query function of digital sulfuric acid APP is to query the physical property parameters of sulfuric acid, such as molar mass, density, specific volume, specific enthalpy, specific entropy, vapor pressure, boiling point, latent heat of vaporization, thermal conductivity, etc., which can provide a scientific basis for the production, storage, transportation and use of sulfuric acid. These parameters are the basis for understanding and controlling the physical and chemical properties of sulfuric acid and are essential for ensuring the stability and safety of the production process. For example, by adjusting the temperature, pressure and other conditions, the vapor pressure and boiling point of sulfuric acid can be controlled, thereby optimizing the efficiency of distillation, rectification and other processes. In addition, the parameter query function of the digital sulfuric acid APP facilitates the research and development of sulfuric acid industry technology. Technicians can use the APP to query various physical parameters of sulfuric acid to support their research work. For example, when studying the reaction mechanism between sulfuric acid and other substances, it is necessary to understand the physical property parameters of sulfuric acid to build reasonable reaction conditions, provide data support for technicians, and help them verify the accuracy and reliability of experimental results. In the material balance, the system uses the material balance algorithm to calculate according to the user's input data. The algorithm will consider the measurement relationship of chemical reaction, material loss, conversion rate and other factors. The calculation results will be displayed on the front interface in real time, including the temperature, flow rate, pressure, concentration and other information that each reaction vessel should have. Material balance is a key step to ensure that the quantity and quality of various raw materials and products in the production process of sulfuric acid meet the established standards, which helps to monitor and control the production process to ensure the quality and efficiency of the product.

Parameter Query

In the parameter query function, users can query data for different types of substances. Our convenient sulfuric acid data parameter query function enables users to quickly check the relevant parameters of sulfuric acid, including but not limited to the density and solubility of sulfur dioxide aqueous solution, as well as the density of fuming sulfuric acid at different concentrations and concentrations at different temperatures. In the sulfuric acid production industry, in order to improve production efficiency, ensure product quality and strengthen safety management, an application program that can query production parameters in real time and accurately is urgently needed. The parameter query function of the Digital Sulfuric Acid APP is designed to meet the following core requirements:

The physical property parameters of gases commonly used in sulfur acid production (oxygen, nitrogen, hydrogen, water vapor, sulfur dioxide, sulfur trioxide, carbon monoxide, carbon dioxide, nitrogen oxide, ammonia, fluorine, hydrogen fluoride) can be quickly queried. The parameter query of sulfur involves saturated vapor density of sulfur, thermal type of sulfur, physical property parameters of liquid sulfur. Sulfuric acid parameter query includes: The density of niacin (15-45 ° C), the concentration of niacin solution (20 ° C), the viscosity of niacin at 15-50 ° C, the heat capacity of niacin at 30 ° C, the density of sulfuric acid (0-100 ° C), the heat capacity of sulfuric acid (-20-150 ° C), the enthalpy of sulfuric acid (20-250 ° C), the thermal conductivity of sulfuric acid, the conductivity of sulfuric acid. The parameter query of water and water vapor includes: the viscosity of water, the physical property parameters of saturated water, and the physical property parameters of saturated water vapor. The implementation cases are as follows:

Example 1: In the digital sulfuric acid APP parameter query function module, the types of commonly used gases can be selected, such as nitrogen oxide, the query result shows the basic information of nitrogen oxide including: gas name: nitrogen oxide, molecular formula: NO, relative molecular mass: 30.01, density: 1.340 (Kg/m3), gas constant: K (28.26 (Kg• m/(Kg• ℃), melting point: -161.0℃, melting heat: 18.4 (× 4.19 J/g), boiling point: -151℃ (101.3KPa), latent heat of vaporization: (106.6 (× 4.19 KJ/Kg) (101.3KPa)), specific heat of Cp per kg: (0.23 (15) (20℃, 101.3KPa)), critical temperature: -94℃, thermal conductivity: 0.019 (× 1.163 W/(m• K)(standard condition), viscosity: η =187.6 (20) (μ Pa• s).
