New to the industry, seeking advice: what are the standards to be referenced in the design of modified asphalt reaction kettles?
Thread Content
A newcomer to the field seeking advice: To which category do modified asphalt reaction kettles belong, and what standards are used for their design and calculation? What type of container is a horizontal continuous production reactor equipped with smoke exhaust (for the reaction fumes inside the reactor), and what standards should be followed for its design? Thank you! ! !

For the design of container-type equipment, the process engineering department should prepare a \"equipment design specification sheet\", which should include the design parameters and requirements for the equipment, a list of connections, specifications for design, manufacturing, inspection, and acceptance, as well as other requirements; it should also contain a schematic diagram of the equipment and a diagram showing the locations of the pipe connections. For example, the pressure of the container (design pressure, operating pressure), temperature (design temperature, operating temperature), medium (name, components, density, properties, flammability, toxicity level, etc.), installation type (upright, horizontal), cross-sectional shape of the container (rectangular, circular), specifications (diameter, length or height), volume (total volume, operating volume), the types and quantities of safety devices installed on the container (safety valves, rupture disks, level gauges, etc.), a schematic diagram of the equipment, a layout diagram of the pipe connections, and so on. 2. Based on the technical specifications outlined in the “Equipment Design Conditions Diagram” for the container, the relevant engineering department is responsible for determining the specific design standards and regulations. 3. When the design pressure of the equipment is not greater than 35 MPa and the design temperature range is between -269°C and 900°C, it shall be designed, manufactured, inspected, and accepted in accordance with GB 150-2011 “Pressure Vessels”. 4. When a device meets all of the following three conditions, it is considered a pressure vessel and must also be subject to the supervision stipulated in TSG 21-2016, \"Safety Technical Supervision Regulations for Fixed Pressure Vessels\". (1) Working pressure greater than or equal to 0.1 MPa ； (2) The volume is 0.03 m3 or more, and the inner diameter is 150 mm or more ； (3) The medium contained is a gas, a liquefied gas, or a liquid whose maximum operating temperature is higher than or equal to its standard boiling point. 5. When the design pressure of the equipment is greater than -0.02 MPa and less than 0.1 MPa, it is considered a atmospheric-pressure vessel, which shall be designed, manufactured, inspected, and accepted in accordance with NB/T 47003.1-2009 \"Steel Welded Atmospheric-Pressure Vessels\". 6. The ones listed above are the main specifications for equipment design and manufacturing; in addition, corresponding technical standards and specifications should be followed based on the technical parameters of the equipment. For example, horizontal containers shall also comply with the provisions of NB/T 47042-2014 \"Horizontal Containers\".
Thank you for the guidance from nj1952!
If the reaction vessel is equipped with a stirring shaft, design should also be carried out in accordance with HG/T20569-2013 \"Stirring Equipment\"
Thank you, Angela, for your excellent guidance! :handshake
