High-Pressure Hydrogenation Reactor

High pressure hydrogenation reactor is a key pressure-bearing equipment for catalytic hydrogenation, hydrogenation reduction and other critical reactions under high temperature and high-pressure hydrogen environment. Its basic principle is to achieve full contact and reaction between hydrogen and organic materials through precise pressure control (0.1–35MPa), temperature control (-20℃ to 400℃) and efficient stirring in a closed kettle, so as to complete unsaturated bond reduction, nitro amination, hydrofining, hydrogenation polymerization and other processes, providing a stable and efficient reaction environment for pharmaceutical intermediates, fine chemicals, high-end materials and energy products Reference: Chem17 – Technical Principle of High Pressure Hydrogenation Reactor. As a source factory of chemical equipment integrating R&D, design, manufacturing, installation, commissioning and general contracting, AIX Boiler focuses on the R&D and manufacturing of high-pressure hydrogenation reactors. We strictly implement GB150 Standardization Administration of China and TSG 21 Specifications for Safety Technology Supervision of Fixed Pressure Vessels, and carry out full-process quality control from material selection, welding forming, non-destructive testing, pressure test to explosion-proof and anti-corrosion treatment, providing highly reliable and safe hydrogenation reaction equipment and overall solutions for global users.

1. Product Overview of AIX Boiler High Pressure Hydrogenation Reactor

AIX Boiler high pressure hydrogenation reactor is mainly made of 316L stainless steel, Hastelloy, titanium and other hydrogen embrittlement resistant materials, suitable for laboratory tests, pilot scale-up and industrial large-scale production. It has core advantages such as high pressure level, excellent sealing performance, explosion-proof safety, precise temperature control and convenient maintenance. We provide customized solutions for different working conditions: 316L stainless steel hydrogenation reactors are selected for conventional hydrogenation scenarios, balancing corrosion resistance and economy; Hastelloy (C-276) or titanium hydrogenation reactors are adopted for strong corrosion or high-purity scenarios, resistant to harsh media such as H₂/H₂S and Cl⁻. At the same time, customized configurations such as explosion-proof type, magnetic seal type and automated PLC/DCS integrated type are supported to meet strict specifications such as pharmaceutical GMP and petrochemical explosion protection. As a source factory, AIX Boiler can customize volume, pressure, temperature, stirring form, heating/cooling method, opening layout, sealing structure and automatic control scheme according to users' process parameters, truly realizing one reactor for one process and one reactor for one scheme.

2. Core Structure and Safety System

AIX Boiler high pressure hydrogenation reactor consists of kettle body, kettle cover, jacket/heat exchange system, magnetic/mechanical sealed stirring system, hydrogen intake distribution system, safety accessories and automatic control system. All systems work together to ensure stable, safe and efficient reaction:

• Kettle Body and Kettle Cover: Made of high-quality hydrogen embrittlement resistant materials by forging or plate rolling and welding. The head is elliptical/spherical structure with uniform pressure and reasonable stress distribution. Welding complies with pressure vessel standards and passes 100% non-destructive testing (RT, UT, PT) to ensure no leakage. The inner wall is electrolytically polished to Ra0.2μm to reduce wall hanging and side reactions;

• Heat Exchange System: Standard jacket/inner coil structure. Heating methods include electric heating, heat conduction oil and steam heating; cooling adopts circulating cooling water with sufficient heat exchange area and temperature control accuracy within ±2℃, suitable for rapid heating and cooling processes;

• Sealing and Stirring System: Magnetic coupling seal is adopted as core configuration to realize non-contact power transmission, completely eliminating shaft seal leakage risk and suitable for high-pressure hydrogen and flammable and explosive media. Propeller, self-priming and turbine three-layer combined blades are optional, with rotating speed up to 1200r/min, forming vacuum hydrogen absorption effect and improving reaction efficiency by more than 35%;

• Hydrogen Intake Distribution System: Built-in gas distributor ensures uniform dispersion of hydrogen in materials and improves gas-liquid mass transfer efficiency. Equipped with high-pressure hydrogen pressure reducing valve, flowmeter, pressure gauge and hydrogen leakage detector to monitor intake pressure and concentration in real time for safety;

• Safety Accessories: Standard safety valve, bursting disc, explosion-proof motor, emergency pressure relief system, dual temperature/pressure interlock protection, explosion-proof grade Ex d IIB T4, to avoid safety accidents caused by overpressure, overtemperature and leakage;

• Opening and Installation: Feed inlet, discharge outlet, manhole, sight glass, temperature measuring port, pressure measuring port, catalyst feeding port, sampling port, etc. can be customized according to process requirements. Support or ear-type structure is adopted to adapt to floor, platform, frame and other installation scenarios.
