High-pressure Reactor

Product Introduction

A high-pressure reactor is a sealed vessel used for chemical reactions, polymerization, and synthetic processes under high pressure. It is generally composed of a reactor body, sealing devices, a stirring system, and heating/cooling systems.

The reactor body is primarily made of 1cr18Ni10Ti stainless steel, and can also be fabricated from titanium (TA2), nickel (Ni6), or composite steel plates according to specific media requirements.

The reactor body structure includes flat covers, convex covers, and closed-type reactor bodies with manholes. Openings on the reactor cover can be designed according to user specifications.

Heating methods include jacketed steam, jacketed hot oil with electric heating, etc., which users can select during ordering.

The inner surface of the reactor body can achieve a mirror-polished finish of [specify level] for applications requiring polishing. For high-viscosity materials, the reactor bottom can be designed as conical to facilitate discharging and cleaning.

Structural Design

Reactor Body

• Usually fabricated from high-strength alloy steel plates or composite steel plates to withstand high pressure.
• The inner side is generally lined with materials resistant to media corrosion.
• The reactor body is a high-pressure cylinder with a thick shell, typically without openings. Pipes, interfaces, and accessories are located on the reactor cover.
• The reactor body is connected to the flange via threads for easy installation and disassembly.

Sealing Devices

• Sealing between the reactor body and cover: Usually, gasket sealing or line-contact sealing forms of conical and arc surfaces are adopted.
• Sealing at the magnetic stirrer: The magnetic stirrer is connected to the reactor cover using a high-pressure flange and screws, with a static seal achieved via metal or non-metal gaskets.
• Shaft sealing devices: Common types include magnetic coupling seals and mechanical seals.

Stirring System

• Driving methods mainly include motor-reducer drives and servo motor drives.
• Stirring blades can be selected according to reaction media and process requirements, such as propeller, turbine, anchor, or ribbon types, to ensure thorough mixing of materials.

Heating/Cooling Systems

• Heating methods can be selected based on user requirements, including steam heating, water-bath circulation heating, thermal oil circulation, thermal oil electric heating, and far-infrared heating.
• Cooling methods: Generally achieved by installing cooling water jackets on the reactor body or stirrer and circulating cooling water.

Technical Parameters

• Heating methods: Jacketed, half-pipe, coil, etc.
• Sealing type: Magnetic seal
• Main materials: Carbon steel, stainless steel, composites, special materials (including titanium, nickel-based alloys, Hastelloy, Monel, etc.)

Application Areas

• Chemical industry: Ammonia synthesis, methanol production, polymer material polymerization, etc.
• Petroleum processing: Hydrogenation reactions, catalytic cracking, etc.
• Pharmaceutical and food industries: High-pressure sterilization, high-pressure synthesis in biopharmaceuticals.
• Research: Experimental studies in materials science, catalytic reactions, etc.

Cleaning Requirements

• Fill the reactor with reaction solvent through the exhaust valve to remove most residues. Then, fill half the reactor with water and stir for 10 minutes before opening the cover for internal cleaning.
• During cleaning, ensure the reactor cover and sampling valve are cleaned. Slightly pressurize with nitrogen when the reactor contains water.
• For reactors not in use, fill 70% of the volume with clean anhydrous ethanol for storage. Do not fully tighten the screws.
