■ Product Overview

This high-pressure air cooling corrosion inhibitor is specially developed for the high-pressure air cooling system of hydrogenation units, aiming to effectively address the serious corrosion problems in the system. During the operation of the hydrogenation unit, the high-pressure air cooler faces a complex environment of high temperature, high pressure, and corrosive media such as hydrogen sulfide, ammonia, and hydrogen chloride, which can easily cause equipment corrosion, leading to equipment leakage and damage, and affecting the safe and stable operation of the unit. This corrosion inhibitor can form a tough and dense protective film on the metal surface through a unique chemical adsorption and film formation mechanism, effectively preventing corrosive media from contacting the metal, thereby significantly reducing the corrosion rate of equipment, extending the service life of high-pressure air cooling equipment, and ensuring the long-term stable operation of hydrogenation units.

■ Productcharacteristic

Efficient corrosion inhibition: The unique formula enables it to have excellent inhibitory ability against common corrosion types in high-pressure air cooling systems of hydrogenation units, such as hydrogen sulfide corrosion, ammonium chloride corrosion, electrochemical corrosion, etc. It can significantly reduce the corrosion rate of equipment, control the corrosion rate at an extremely low level, effectively extend the maintenance cycle of equipment, and reduce the number of unplanned shutdowns caused by equipment corrosion.

Quick film formation: It can quickly undergo chemical adsorption on the metal surface, forming a uniform and dense protective film. Generally, the initial film formation process can be completed in a short period of time (usually several hours), providing timely and effective protection for the equipment, especially suitable for the start-up and shutdown stages of the device and working conditions with sudden increase in corrosion risk.

long-lasting protection: The formed protective film has good adhesion and stability, and can maintain integrity for a long time under harsh working conditions of high-pressure air cooling systems, continuously playing a role in corrosion inhibition. Even in complex situations such as medium fluctuations, temperature and pressure changes, it can effectively resist the erosion of corrosive media, ensuring that the equipment remains in a low corrosion state for a long time.

Strong compatibility: Fully considering the process characteristics of the hydrogenation unit, it has good compatibility with the process medium, other additives, and equipment materials in the high-pressure air cooling system. It will not interfere with the normal hydrogenation reaction process, nor will it have adverse reactions with other chemicals, ensuring the safe and stable operation of the device.

Safety and Environmental Protection: Select environmentally friendly raw materials that comply with relevant safety and environmental standards. During use, it ensures the safety of operators and poses minimal environmental hazards. After use, harmful substances will not remain in the device or environment, making it easy to handle and in line with the development concept of green chemistry.

■ Scope of application

This high-pressure air cooling corrosion inhibitor is suitable for high-pressure air cooling systems in various refinery hydrogenation units, specifically covering the following key parts:

High pressure air cooler bundle: The core components of high-pressure air coolers come into direct contact with corrosive media, posing a high risk of corrosion. Corrosion inhibitors can form a protective film on the surface of the tube bundle, effectively preventing corrosive media such as hydrogen sulfide and ammonium chloride from corroding the tube bundle, extending its service life, and avoiding device shutdown caused by tube bundle corrosion leakage.

High pressure air cooler inlet and outlet pipelines: In import and export pipelines, due to the high-speed flow of the medium and changes in temperature and pressure, it is easy to cause erosion corrosion and corrosion under scale. Corrosion inhibitors can form a protective film on the inner wall of pipelines, reducing the erosion of media on pipelines, ensuring the safe operation of pipelines, and guaranteeing the smooth transportation of materials.

High pressure air cooler separator tank: The medium inside the separation tank is in a gas-liquid mixed state and contains a large amount of corrosive components, making the tank wall and internal components susceptible to corrosion. The addition of corrosion inhibitors can form a protective film on the surface of the tank wall and internal components, preventing corrosion, ensuring the normal operation of the separation tank, and improving the separation efficiency of the device.
