Hydrogenation Reactor Safety Guidelines

The hydrogenation reactor is suitable for the production of xylitol, maltitol, and similar substances. During operation, strictly follow the instructions in the product manual regarding cooling, lubrication, heating, and other procedures to ensure proper equipment maintenance and care. Operate the reactor strictly according to the working pressure and temperature specified on the high-pressure reactor nameplate to avoid potential hazards. When using any valves, slowly rotate the valve stem to tightly seal the sealing surface, ensuring effective sealing of the high-pressure reactor. Avoid excessive force when closing valves to prevent damage to the sealing surfaces. Electrical control instruments should be operated by designated personnel only.

Hydrogenation Reactor Safety Guidelines

1. The hydrogenation reactor must be operated by designated personnel, and operations require two or more people simultaneously. Only full-time staff qualified in this field may serve as operators; temporary workers may only perform auxiliary tasks and are not permitted to independently carry out hydrogen charging or discharging operations.

2. Operators must fully understand the chemical structure and physical-chemical properties of the reactants involved in the hydrogenation process; otherwise, they have the right to refuse the experiment. They must also be thoroughly familiar with the performance and handling requirements of the catalysts used, and must not arbitrarily increase catalyst dosage. Solvents used must be of analytical purity or higher; solvents below industrial grade that may contain oxides or peroxides are strictly prohibited.

3. Operations must strictly follow the high-pressure hydrogenation reactor operating procedures, with each step performed carefully and meticulously. Experiments exceeding the technical specifications of the reactor—such as ultra-high temperature, ultra-high pressure, ultra-high viscosity, excessive volume, or rapid heating/cooling—are strictly forbidden. Solvents that corrode or damage the reactor (e.g., strong acids) must not be used. Any violation of operational regulations must be immediately stopped by the designated operator.

4. Before entering the high-pressure hydrogenation reactor experimental area at the beginning and end of each workday, ventilation fans must be turned on for air exchange. Forced ventilation must be activated during hydrogen charging and discharging operations, and ventilation fans should be periodically operated throughout the work period. At the end of the workday and on holidays, all power and water sources in the operation zone must be shut off. Confirm that hydrogen cylinder valves are properly closed and functioning normally, close doors and windows, and activate the hydrogen leak pre-alarm system.

5. Smoking is strictly prohibited within the high-pressure hydrogenation reactor experimental area. All activities that could produce open flames or sparks are forbidden, including wearing leather shoes with metal nails, wearing synthetic fiber clothing prone to sparking, and bringing mobile communication devices into explosion-proof operation rooms.

6. Ordinary electrical plugs and switches must not be installed or used in explosion-proof operation rooms or hydrogen storage areas. If temporary electrical use is necessary, the power cord must first be securely connected before turning on the explosion-proof switch.
