Products Introduction
To determine whether a high pressure high temperature reactor can withstand high-pressure and high-temperature conditions, the following considerations and verifications are usually required:
|
◆ Material selection: Choose pressure-resistant materials suitable for working under high pressure and high temperature conditions, such as pressure-resistant steel. For specific reaction conditions, it is necessary to ensure that the material has sufficient tensile strength, heat resistance and corrosion resistance.
◆ Pressure vessel design: Design and calculate the pressure vessel according to the expected maximum pressure and temperature. This includes determining the wall thickness of the container, the support and connection mode of the internal structure of the container, etc. The design process usually follows the relevant international or industrial standards, such as ASME (american society of mechanical engineers) code.
◆ Strength calculation: The strength of the container is evaluated through the calculation of stress and deformation. This includes stress analysis, fatigue life analysis and consideration of thermal expansion effect of different parts. The calculation process can be simulated and verified by engineering software such as finite element analysis (FEA).
◆ Safety valve and protection device: Safety valve is set on the high-pressure laboratory reactor to release excessive pressure, and other protection devices, such as overflow device, temperature sensor and emergency stop device, need to be considered.
◆ Experimental verification: Before the actual operation, a series of experimental verification, such as pressure test, temperature cycle test and safety performance test, are needed to ensure that the high-pressure reactor can work stably and reliably. |

Products Features
Mechanical stirring and magnetic stirring are two common stirring methods, and there are some differences between them in realizing stirring effect and application scenarios.
|
|
◆ Principle: Mechanical stirring is to provide mechanical energy through mechanical equipment (such as stirrers, paddles, etc.), and transfer the energy to the liquid or mixture to make it flow and stir. Magnetic stirring is to use the magnetic field generated by a rotating magneton (magneton) with magnetic force to drive the magneton to rotate in the container through the magnet outside the container, so as to realize the stirring effect. ◆ Stirring mode: Mechanical stirring usually uses rotating stirring devices, such as paddles, scrapers, screws, etc., to shear, stir and mix liquids or mixtures. Magnetic stirring realizes the stirring of liquid by transferring magnetic force through the container wall without direct contact with liquid through magnetic force transfer and eddy current effect. ◆ Operation requirements: Mechanical stirring requires additional mechanical devices and power transmission systems, and usually requires motors or transmission devices to drive the agitator. However, magnetic stirring does not require mechanical parts to enter the liquid, which reduces the pollution and maintenance requirements of the stirred materials. ◆ Application scenario: Mechanical stirring is suitable for most stirring requirements, especially for materials with high viscosity and large particles or reaction processes with certain shear requirements. Magnetic stirring is suitable for environments that require high purity of materials, such as biomedicine, food and cosmetics, because no mechanical parts enter the liquid. |
Knowledge
ASME (american society of mechanical engineers) has formulated a series of specifications and standards, which are applicable to the design, manufacture and operation of high pressure high temperature reactors. The following are some common related specifications:
◆ Asme boiler and pressure vessel code: This code includes many parts, among which Section VIII-Division 1 and Division 2 are usually used for the design of high-pressure and high-temperature reactors. These specifications cover the design, material selection, manufacture, inspection and testing of containers.
◆ Asme b31.3 process piping (ASME b31.3 process piping specification): This specification is applicable to the design and construction of inlet and outlet piping systems of high pressure and high temperature reactors. It includes the calculation of pressure, temperature and other parameters of pipeline system, material selection, welding, supporting and testing.
◆ Asme PCC-1 bolted flange joint assembly: This specification provides guidance for the design, installation, fastening and inspection of bolted flange joints in high pressure and high temperature reactors.
In addition, there are other ASME codes and standards related to high-pressure and high-temperature reactors, including ASME B16.5 (steel flange and flange connection standard), ASME B16.34 (valve specification), ASME PTC 19.3 TW (temperature measurement guide) and so on.
Case Studies
► Case Study 1: Synthetic Diamond Production via HPHT Reactors
Industry: Materials Science
Company: Element Six (De Beers Group)
Objective: Produce industrial-grade diamonds for cutting tools, electronics, and optics.
● Background
Synthetic diamonds are manufactured using HPHT reactors that mimic the geological conditions under which natural diamonds form. Element Six, a leader in superhard materials, employs a belt press reactor design, applying pressures up to 6 GPa and temperatures of 1,400–1,600°C to convert graphite into diamond.
