Jacketed Reactor: Jacket Cleaning

The jacketed reactor is a device that stirs a certain volume of two or more liquids and liquid and solid or gas materials with the help of a stirrer under a certain pressure and temperature to promote their reaction. The jacket on the jacketed reactor body is mainly used for heating and cooling. Depending on the materials, steam or cooling water is often circulated in the reactor jacket. The reactor jacket is a heat exchange device, so There inevitably are scaling and corrosion problems.

Reasons for cleaning jacketed reactor jacket

What is dirt? Fouling is “the accumulation of unwanted substances on a solid surface, thereby impairing the function of the object”. General chemical enterprises need to use the reactor jacket to cool and heat the materials. If water treatment is not performed, the corrosion and scaling of the reactor jacket will be very serious, and the corrosion and scaling of the reactor jacket will seriously affect the heat exchange effect of the jacketed reactor. The cooling and heating effects of the jacketed reactor are greatly reduced, and the service life of the jacketed reactor will be greatly shortened. Due to the reduced heat exchange and cooling effects of the reactor jacket, the reaction and cooling/heating processes will be prolonged. It will affect the production schedule and product quality.

Jacketed reactor jacket cleaning steps

1. Use GJ-high-efficiency sterilizing slime stripping agent plus penetration enhancer and dispersant for chemical cleaning of the reactor jacket to remove biological slime and soft scale in the reactor jacket;

2. Use GJ-2E rust and scale remover to remove hard scale, soft scale, and rust in the reactor jacket and restore the clean metal surface of the jacket reactor;

3. Passivate the pre-film on the clean metal surface of the reactor jacket after cleaning to form a corrosion-resistant protective layer. After cleaning the scale on the reactor jacket, add a metal pre-film agent to form a passivation film on the metal surface of the reactor jacket to be cleaned. A thin film of insoluble oxide is formed to protect the jacket metal of the clean-jacketed reactor from oxidation reactions. Prevents corrosion of reactor jacket after cleaning. It is characterized by high efficiency of cleaning and descaling of the reactor jacket, low cleaning cost, basically no corrosion on the carbon steel reactor jacket and stainless steel reactor jacket, and is especially suitable for cleaning slime, scale, and hard scale of the reactor jacket Rust cleaning. After the reactor jacket is cleaned, the production reaction time is shortened by more than 30%.

Advantages after reactor jacket cleaning

1. Improve the heat exchange cooling effect and reduce accidents: After cleaning the reactor jacket, the biological slime and soft scale in the jacket can be removed, making the jacket of the jacketed reactor unobstructed and the water quality clear. At the same time, the heat exchange efficiency of the reactor jacket is improved, the cooling effect is improved, and the product process, quality, and energy are saved by more than 10-30% so that the jacketed reactor can operate safely and efficiently;

2. Protect the jacketed reactor and extend its service life: After the reactor jacket is cleaned, it can prevent rust and scaling. Avoid corrosion and damage of the heat exchanger. After adding a corrosion inhibitor, the corrosion rate of the jacketed reactor can be reduced by 90%, and its service life can be doubled;

3. Energy saving, water saving, cost reduction: Reactor jacket cleaning can remove scale, prevent scaling, improve heat exchange efficiency, and reduce power or fuel consumption. The cleaning of the reactor jacket can increase the concentration ratio, reduce the amount of sewage discharge, and improve the utilization rate of circulating water;

4. Save a lot of maintenance costs and eliminate production losses: If the reactor jacket is not cleaned, the jacketed reactor will be clogged, scaled, corroded, and even unable to produce normally during use.

The jacketed reactor is one of the commonly used equipment in the factory, and it is essential to clean the dirt in the jacket. This can reduce the occurrence of accidents, prolong the service life of equipment, save energy and water, reduce costs, save maintenance costs, and stop production losses.
