Introduction

In modern industrial production, pipeline systems play a crucial role. Whether it is conveying liquid, gas or solid particles, the efficiency and reliability of the pipeline system directly affect the smoothness and cost control of the entire production process. With the continuous improvement of global energy conservation and environmental protection requirements, how to improve the efficiency of pipeline systems and reduce energy consumption and environmental pollution has become the focus of attention of the industry. As a new chemical additive, triethylenediamine (TEDA) is becoming a new choice to improve the effectiveness of industrial pipeline systems due to its unique properties. This article will explore in detail the application of TEDA in industrial pipeline systems and how it can help achieve the goals of higher efficiency, energy saving and environmental protection.

1. Basic introduction to triethylenediamine (TEDA)

1.1 What is triethylenediamine (TEDA)?

Triethylenediamine (TEDA), with the chemical formula C6H12N2, is a colorless to light yellow liquid with a strong ammonia odor. It is an important organic compound and is widely used in chemical industry, medicine, pesticide and other fields. TEDA has excellent chemical stability and thermal stability, and can maintain its performance in high temperature and high pressure environments.

1.2 Main features of TEDA

High boiling point: TEDA has a higher boiling point and is suitable for use in high temperature environments.
Low Volatility: TEDA has lower volatility, reducing losses in the pipeline system.
Good solubility: TEDA is compatible with a variety of organic and inorganic substances and is easy to disperse in the pipeline system.
Environmentality: TEDA is low in toxicity, is environmentally friendly, and meets the requirements of modern industry for environmental protection.

1.3 Application areas of TEDA

The application of TEDA in industrial pipeline systems is mainly reflected in the following aspects:

Anticorrosion agent: TEDA can effectively prevent corrosion of the inner wall of the pipe and extend the service life of the pipe.
Scale Inhibitor: TEDA can inhibit scaling on the inner wall of the pipe and keep the pipe unobstructed.
Lutrient: TEDA can reduce frictional resistance of fluids in pipes and reduce energy consumption.
StabilizerTEDA can stabilize the chemical properties of fluids in the pipeline and prevent fluid from deteriorating.

2. Application of TEDA in industrial pipeline systems

2.1 Anticorrosion agent

2.1.1 The impact of corrosion on pipeline systems

The corrosion problem of pipeline systems has always been a major challenge facing the industrial community. Corrosion will not only lead to thinning of the pipe wall thickness, reducing the strength and durability of the pipe, but may also cause leakage accidents, causing environmental pollution and property losses. In addition, corrosion products can clog the pipeline, affect the normal delivery of fluid and increase energy consumption.

2.1.2 Anti-corrosion mechanism of TEDA

As an efficient anticorrosion agent, TEDA’s mechanism of action is mainly reflected in the following aspects:

Form a protective film: TEDA can form a dense protective film on the inner wall of the pipe to isolate the contact between the corrosive medium and the metal surface, thereby preventing corrosion.
Neutrifying acidic substances: TEDA is alkaline and can neutralize acidic substances in the fluid in the pipeline and reduce the corrosion rate.
Inhibit electrochemical reactions: TEDA can inhibit electrochemical reactions on metal surfaces, reduce corrosion current, and thus slow down the corrosion process.

2.1.3 Application Cases

The pipeline system of a chemical plant is corroded by acidic media for a long time, resulting in frequent pipeline replacement and increasing production costs. After the introduction of TEDA as an anticorrosion agent, the service life of the pipeline was significantly extended, the corrosion rate was reduced by more than 50%, and the annual maintenance cost was saved by more than 1 million yuan.

2.2 Scale inhibitor

2.2.1 The impact of scaling on pipeline systems

The scaling problem in the inner wall of the pipe cannot be ignored. Scale will reduce the effective circulation area of ??the pipeline, increase the flow resistance of the fluid, and lead to an increase in energy consumption. In addition, scaling will affect the heat transfer efficiency of the fluid and reduce the operating efficiency of the production equipment.

2.2.2 TEDA’s scale inhibition mechanism

As an efficient scale inhibitor, TEDA’s mechanism of action is mainly reflected in the following aspects:

Dispersion: TEDA can disperse solid particles in the fluid in the pipeline to prevent them from depositing on the inner wall of the pipeline.
Chalization: TEDA can form stable chelates with metal ions such as calcium and magnesium in the fluid to prevent them from forming scale.
lattice distortion: TEDA can change the growth of scale crystalsThe long way makes it form a loose crystal structure and is easily taken away by the fluid.

2.2.3 Application Cases

The cooling water pipeline system of a thermal power plant has been plagued by scale for a long time, resulting in a decrease in cooling efficiency and an increase in energy consumption. After the introduction of TEDA as a scale inhibitor, the scale deposit amount on the inner wall of the pipeline was reduced by 80%, the cooling efficiency was improved by 15%, and the annual electricity bill was saved by more than 500,000 yuan.

2.3 Lubricant

2.3.1 The impact of friction on pipeline system

In the flow of fluid in the pipeline, the frictional resistance between the fluid and the inner wall of the pipeline is one of the main sources of energy consumption. The greater the friction resistance, the slower the flow rate of the fluid and the higher the energy consumption. In addition, friction will cause wear on the inner wall of the pipe, shortening the service life of the pipe.

2.3.2 Lubrication mechanism of TEDA

As an efficient lubricant, TEDA’s mechanism of action is mainly reflected in the following aspects:

Reduce surface tension: TEDA can reduce surface tension between the fluid and the inner wall of the pipe and reduce friction resistance.
Formation of lubricating film: TEDA can form a lubricating film on the inner wall of the pipe, reducing direct contact between the fluid and the inner wall of the pipe, thereby reducing friction.
Improving fluid flow: TEDA can improve fluid flow, make it flow smoother in the pipeline and reduce energy consumption.

2.3.3 Application Cases

A certain oil conveying pipeline system has a high fluid viscosity, resulting in a large energy consumption of conveying. After the introduction of TEDA as lubricant, the frictional resistance of the fluid was reduced by 30%, the energy consumption was reduced by 20%, and the annual electricity bill was saved by more than 2 million yuan.

2.4 Stabilizer

2.4.1 Effect of fluid deterioration on pipeline system

The chemical properties of the fluid in the pipeline are unstable, and oxidation, polymerization and other reactions are prone to occur, resulting in the deterioration of the fluid. Deteriorated fluids not only affect the stability of the production process, but may also cause damage to the pipeline system and increase maintenance costs.

2.4.2 Stabilization mechanism of TEDA

As an efficient stabilizer, TEDA’s mechanism of action is mainly reflected in the following aspects:

Antioxidation effect: TEDA can inhibit oxidation reactions in the fluid and prevent the fluid from deteriorating.
Inhibiting polymerization reaction: TEDA can inhibit polymerization reaction in fluids and prevent increased fluid viscosity.
Stable chemical properties: TEDA can stabilize the chemical properties of fluids and keep them stable in the pipeline system for a long time.

2.4.3 Application Cases

The organic solvent delivery pipeline system of a chemical plant is prone to oxidation, causing the solvent to deteriorate and affecting the production quality. After the introduction of TEDA as a stabilizer, the oxidation rate of the solvent was reduced by 70%, the production quality was significantly improved, and the annual cost of solvent replacement was saved by more than 1.5 million yuan.
