The high-pressure reactor is ushering in a new lease on life.

The high-pressure reactor fundamentally addresses the shaft seal leakage issues that previously could not be overcome by packing seals or mechanical seals, featuring zero leakage and zero contamination. It is currently the most ideal equipment in China for conducting chemical reactions under high temperature and high pressure conditions. Weihai, located at the eastern tip of the Shandong Peninsula and bordered on three sides—north, east, and south—by the Yellow Sea, is one of China’s major production centers for reactors. In particular, Weihai ranks among the nation’s leaders in terms of the scale of high-pressure reactor production, production standards, and manufacturing processes. Weihai Zikong Reactor Co., Ltd. is one of the earliest enterprises in Weihai engaged in the manufacture of reactors and high-pressure reactors, and it boasts its own well-known trademark as well as the world’s most advanced production technology.

Key Considerations for Selecting a Pilot-Scale Hydrogenation Autoclave

The pilot-scale hydrogenation autoclave is a product positioned between laboratory hydrogenation autoclaves and industrial hydrogenation autoclaves. Its key distinguishing feature is its larger volume compared to laboratory autoclaves. Moreover, since hydrogenation or hydriding reactions can be highly exothermic, the pilot-scale hydrogenation/hydriding autoclave is equipped with explosion-proof features for both the stirring motor and the electric heating system. Additionally, due to the increased aperture size, laboratory autoclaves typically feature open-top designs, whereas pilot-scale autoclaves are no longer limited to closed designs. Instead, influenced by factors such as pressure, temperature, and volume, they often adopt closed structures. In terms of converting design pressure into working pressure, hydrogenation autoclaves also differ from conventional autoclaves.

Principles for Selecting Bottom-Discharge Valves for Autoclaves

For high-pressure reactors with larger volumes, customers often request the installation of a valve at the bottom of the reactor to facilitate material discharge or reduce the number of times the reactor lid needs to be opened. For users, selecting the right type of valve is crucial, as using a valve that doesn't match the characteristics of the reaction materials can frequently lead to valve damage or excessive residual material remaining inside the reactor. Generally speaking, there are several types of valves commonly chosen for high-pressure reactors used by customers, with ball valves and gate valves (also known as top-and-bottom valves) being the two main options. Depending on the state of the material being discharged, ball valves are primarily used in reactors handling solid materials such as powders and granules. If the material temperature is too high...

Determinants of the Electric Heating Power of an Autoclave

In the process of determining the technical parameters for electrically heated autoclaves, one particularly important technical parameter is the heating power of the autoclave. Here, the editor will briefly introduce the issue of heating power in electrically heated autoclaves to help readers make informed choices. The factors that determine the heating power of an autoclave include the following: 1. The reaction medium inside the autoclave—especially for autoclaves with high reaction temperature requirements, it’s crucial to understand whether the reaction is exothermic or endothermic. 2. The size of the autoclave’s volume—this is easy to understand: when the autoclave’s volume is small, the required heating power is lower; conversely, a larger volume calls for greater heating power. 3. The pressure level required by the autoclave—for applications that demand high pressure...

The configuration issue of the autoclave vent pipe.

Many customers, when purchasing autoclaves, raise questions about the entry and exit of gases during reactions. Below, we’ll briefly address the issue of setting up the gas inlet pipe on autoclaves, making it easier for customers to select an inlet pipe that’s right for their needs. Generally speaking, gases enter the autoclave via a stainless steel tube connected to both the autoclave and the gas cylinder. There are two types of threaded connections on these stainless steel tubes: one is left-handed thread, primarily used for flammable, explosive, or toxic gases such as hydrogen and oxygen; the other is right-handed thread, mainly suited for ordinary gases like nitrogen and argon—these are inert gases. During use, users...
