There are numerous corrosion-resistant materials suitable for pickling. Among them, epoxy resins and modified epoxy resins are the best choices. 2. The principle behind stainless steel pickling is that, after pretreatment, an acidic liquid is used to remove the oxide scale from the steel surface and eliminate surface metal ions, thereby achieving a high degree of surface smoothness and cleanliness. 3. Therefore, the selection of corrosion-resistant materials directly affects the performance of the reactor.

Reactor: A brief introduction to the five key components of a reactor

The five key elements of a reaction vessel are: volume, operating pressure, operating temperature, stirring method, and reaction medium. If these features cannot be utilized effectively, it is not advisable to equip the vessel with all of them—doing so would only increase costs and make operation more cumbersome. If sampling is not required, there’s no need to install a sampling tube, no need for particulate catalysts, no need to fit a filter, and no need for high operating pressure. There’s also no need to design for high operating pressure—for instance, if the pressure gauge lacks digital display, the pressure range is limited, the pressure reading is imprecise, the reactor body becomes heavier, and operation becomes less convenient. 1. As the operating pressure increases, the reaction vessel will become correspondingly thicker and heavier. The pressure gauge’s range and safety...

Reactor: The Difference Between Jacketed Reactors and Conventional Reactors

A reactor is a vessel used for chemical reactions. With the growing pool of talent and continuous technological advancements, reactors have gradually evolved from conventional reactors to external coil reactors. Today, I’d like to introduce the differences between external coil reactors and conventional reactors. The external coil reactor boasts strong automatic operation capabilities; it allows pre-setting of speed and enables precise control over several key parameters during the reaction process. External coil reactors operate with low noise levels, exhibit excellent stability, and are easy to clean after use. The equipment can run continuously, facilitating efficient dispersion and mixing of materials. Moreover, the equipment features an outstanding sealing structure—generally, there are no leaks. It also incorporates a built-in discharge system for easy recovery.

Reactor: How to Clean a High-Pressure Reactor

How do you clean a reaction vessel? After purchasing or using it, have you ever cleaned your reaction vessel? I bet not many of you have! Today, our reaction vessel manufacturer is going to show you how to clean an autoclave—let’s take a look! Manual cleaning of a reaction vessel: While low cost is its advantage, before entering the reaction vessel, you’ll need to ventilate it for several hours. Moreover, at any point during the removal process, you must monitor the oxygen concentration inside the vessel, which could pose a risk of hypoxia. At the same time, manual scraping can effectively remove residual traces; however, aside from thorough cleaning, it may also cause the inner walls of the autoclave to become slippery, objectively leaving behind residues.

Reactor: Causes of Reactor Malfunctions

The reaction vessel operates at relatively high pressure. The pressure inside the vessel is either generated by chemical reactions or caused by a rise in temperature. Pressure fluctuations can be significant, sometimes leading to unstable operation. Sudden pressure increases may even exceed the normal pressure several times over. For this reason, most reactors are designed as pressure vessels. Due to the cooling circulation system within the reaction vessel, the sealing requirements are relatively high. However, various factors can occasionally lead to failure. The primary causes of these failures are analyzed below. 1. The main forms of reactor seal failure include: corrosion, thermal loss, wear, and issues arising from installation and operational conditions. Disassembling the high-pressure reactor.

Reactor: How to precisely control the cooling capacity of the reactor?

With societal progress, some industries are placing increasingly higher demands on reaction vessels—particularly those in sectors such as chemical and pharmaceutical manufacturing, where reaction vessels are essential components of the production process. During production, the materials inside the reaction vessel generate significant amounts of heat, which typically need to be cooled using cold water to ensure smooth operations. If the temperature control of a reaction vessel is imbalanced, it can severely affect the reaction process and product quality, leading to substantial waste. In severe cases, the reaction may undergo unintended transformations, resulting in products that are no longer the desired substances. While it’s normal for the temperature of the reaction vessel’s main body to fluctuate during prolonged operation, excessive temperature variations remain a cause for concern.

Reactor: Characteristics and Applications of Reactors

For enterprises, large production capacity is a key advantage: Large-capacity reactors use single-layer reactor walls instead of traditional jacketed reactor walls, eliminating or significantly reducing the external pressure that the reactor must withstand. As a result, these reactors no longer suffer from the heat-transfer limitations inherent in conventional external pressure vessels—limitations caused by excessively thick reactor walls and increased vessel volume. The volume of these reactors can reach 30 m³ or even larger, greatly enhancing the production capacity of each individual reactor. From the perspective of operators and technicians, large-scale autoclaves are easy to maintain: Since the built-in plate-type heat exchangers are detachable, they are simple to clean and repair, helping to reduce operational failures and improve production stability.
