Foreword

The core of the process design of sulfur acid making plant is the material balance data, the equipment required for the construction of the plant is manufactured according to the material balance data, and the boundary of the process parameters of the late operation of the device is controlled around the material balance. Therefore, the material balance data is related to the economy of the operation of the sulfuric acid plant and the current health state of the reaction device. Let's take a look at how the material balance affects the economy of the operation and the health state of the device.

Economy

1. Material balance plays a crucial role in sulfur acid production process, through the material balance can clearly know:

The correlation of molten sulfur fine sulfur treatment, burned sulfur conversion, dry absorption, waste heat recovery, waste heat recovery, and tail gas treatment in the whole reaction process leads the operator to think systematically about the economy of the operation of the device. Sulfur as a raw material, the input and the final output of sulfuric acid, steam need to reach a boundary balance between the input and output, if the input and output do not meet the expectations, there is a negative deviation, the operator through the material balance calculation and systematic thinking can find the problem in time, as soon as possible through manual intervention to bring the device back to the boundary balance, improve the economy and efficiency of the device.

2. Sulfur acid making device is composed of a plurality of sections, each section is composed of a plurality of equipment, each set of equipment has a corresponding material balance, only so that each equipment in the corresponding amount of material and the corresponding load between the balance, in order to make sulfur acid making device in the best state of operation. If the operating parameters of a device break the material balance, the device may be overloaded or the downstream section overloaded, affecting the normal operation and service life of the device.

3. By comparing the difference between the operating material balance parameters and the design material balance parameters in real time, the process parameters can be adjusted in time, so that each key process parameter is close to the design index, which can not only ensure the stability of the operation of the sulfuric acid plant, but also improve the steam production rate and conversion rate of the plant.

Summary

In summary, material balance plays an important guiding role in sulfur acid production. Through material balance, the production process can be optimized, production efficiency can be improved, production costs can be reduced and the impact on the environment can be reduced, so as to achieve high efficiency, environmental protection and sustainable development of sulfur acid production.

Fault found

Material balance helps to identify potential faults or problems in the sulfuric acid process. Specifically, sulfur.     The material balance of sulfonic acid can be analyzed from the following aspects:

1. There is a significant difference between the sulfur consumption and the theoretical yield of sulfuric acid, which may be due to a decrease in conversion, leakage of heat transfer equipment, or improper process parameter conditions (such as temperature, pressure, catalyst activity, etc.).

2. Sulfur acid process is a high energy consumption process, if the abnormal increase in energy consumption, may be due to reduced equipment efficiency, improper operation or poor process conditions. By comparing actual energy consumption with theoretical energy consumption, these problems can be found in time.

Summary

By calculating the material balance parameters, we can timely find the potential faults or the problems of the operation economy decline in the process of sulfur acid production, and take corresponding measures to optimize and improve, to ensure the stability and safety of the production process. At the same time, regular material balance parameter analysis of the device is also an important means to prevent potential failures, so as to effectively improve the operation cycle and economy of the device. Lilly recognizes the importance of material balance to the operation of sulfur acid plants, and the Digital Sulfuric Acid Research and Development Group is now developing material balance software for use in sulfur acid production.
