■ Product Overview

This hydrogenation corrosion inhibitor is specially designed for hydrogenation units in refineries, aiming to solve the serious corrosion problems faced during the operation of the units. In the hydrogenation reaction process, the device needs to withstand high temperature and high pressure environments, and come into contact with process fluids containing highly corrosive media such as hydrogen sulfide, ammonia, and hydrogen chloride, which can easily cause equipment corrosion, leakage, damage, and other situations, seriously threatening the safety and stable operation of the device. This corrosion inhibitor utilizes a unique chemical mechanism to construct a strong and dense protective film on the surface of metals, effectively isolating corrosive media from contact with metals, significantly reducing the corrosion rate of equipment, greatly extending the service life of hydrogenation equipment, and effectively ensuring the long-term stable operation of the equipment.

■ Productcharacteristic

Efficient corrosion inhibition: With innovative formulas, it has demonstrated excellent inhibition ability against various types of corrosion commonly found in 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, significantly reduce the number of unplanned shutdowns caused by equipment corrosion, and reduce the risk of production interruption.

Quick film formation: It can quickly undergo chemical adsorption on the metal surface, forming a uniform and dense protective film in a short period of time. Generally, the initial film formation process can be completed within a few 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, quickly responding to protect the equipment.

long-lasting protection: The formed protective film has good adhesion and stability, and can maintain its integrity for a long time under the harsh working conditions of the hydrogenation unit, continuously exerting its corrosion inhibition effect. Even in the face of complex situations such as fluctuations in medium composition and frequent changes in temperature and pressure, it can effectively resist the erosion of corrosive media, ensure that the equipment is in a low corrosion state for a long time, and guarantee the stable operation of the device.

Widely compatible: Fully considering the complex process characteristics of the hydrogenation unit, it has good compatibility with various process media, other additives, and equipment materials inside the unit. 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 without affecting product quality and production efficiency.

Safety and Environmental Protection: Select environmentally friendly raw materials and strictly follow relevant safety and environmental standards for production. During use, it ensures the safety of operators and poses minimal environmental hazards. After use, there will be no residual harmful substances in the device or environment, making it easy to handle and in line with the development concept of green chemistry, helping enterprises achieve sustainable development.

■scope of application

This hydrogenation unit corrosion inhibitor is suitable for hydrogenation units in various refineries, including but not limited to the following key parts:

Hydrogenation reactor: The core equipment of hydrogenation reaction is located in a high-temperature, high-pressure, and highly corrosive environment inside. Corrosion inhibitors can form protective films on the inner walls and surfaces of internal components of reactors, effectively preventing corrosion of equipment by media such as hydrogen sulfide and hydrogen gas, ensuring the safe and stable operation of reactors, and maintaining the efficient progress of hydrogenation reactions.

High pressure heat exchanger: An important equipment used for heat exchange in hydrogenation units. Due to the temperature and pressure changes of the process fluid during heat exchange, as well as the presence of corrosive components, the heat exchanger tube bundles and shells are susceptible to corrosion. Corrosion inhibitors can form a protective film on the surface of equipment, reducing the impact of corrosion on heat transfer efficiency, extending the service life of heat exchangers, and ensuring the stability of heat transfer.

High pressure air cooler: The tube bundles, inlet and outlet pipelines, and separation tanks 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 metal surfaces of these areas, preventing corrosion caused by media such as hydrogen sulfide and ammonium chloride, avoiding problems such as tube bundle leakage and pipeline perforation, and ensuring the normal operation of the air cooling system.

Pipeline system: Connect the raw oil pipelines, hydrogen pipelines, reaction product pipelines, etc. of various equipment in the hydrogenation unit. In pipelines, the high-speed flow of the medium, as well as temperature and pressure changes, can easily 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.

Low pressure separator: The medium inside the low-pressure separator is in a gas-liquid mixture state, containing a certain amount of corrosive components, and the tank wall and internal components are 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 separator, and improving the separation efficiency of the device.
