A steam-heated jacket encloses the reactor, and a control system regulates the temperature by throttling in/outflow of the liquid chemical solution inside. The control system also monitors the pressure of the reactor vessel.
At the reactor inlet a mass flow controller restricts the maximum flow, while an electronic pressure transmitter measures and displays the pressure.
Reactors for Sale
Reactor is an essential equipment in chemical industry for conducting chemical reactions. These are mainly used in polymer industries, dyes and pigments industries and pharmaceutical industries. There are various types of reactors available in the market with its application and basic principle. There are four main types of reactors Batch Reactor, Continuous Stirred-Tank Reactor (CSTR), Packed Bed Reactor, and Plug Flow Reactor. The selection of the appropriate type of reactor depends on many factors, including reaction conditions and production capacity. Before buying a new chemical reactor, it is recommended to consult with experienced chemical engineers and conduct detailed engineering analyses to ensure that the chosen reactor meets all process requirements and safety considerations.
In addition to the type of reactor, other important aspects to consider include the size and configuration of inlet and outlet ports, agitation system, insulation, and compatibility with the reaction media and operating conditions. It is also crucial to evaluate the material of construction of the reactor vessel and select a reputable manufacturer that offers quality products, technical support, and warranty coverage.
Bronkhorst has developed a specialized combination of electronic pressure control and thermal mass flow controllers for automated pressure control in chemical reactor vessels. This standard solution can be applied to both low-flow laboratory reactions and high-pressure industrial applications. The VP Series of Metal and Dual Seated Piston Valves features dead space free reactor outlet valves that offer maximum flow performance.
Used Reactors
Reactors are used for chemical processing such as petrochemical, food, paper and pulp, pharmaceutical and plastics. They can operate at low or high pressure and come in various vessel sizes, temperature ranges and power specifications. Whether you need a lab reactor system for research and development or a large industrial reactor for hydrogenation or other process applications, surplusrecord can help you find the right equipment.
We offer a wide selection of used reactors from top manufacturers. You can find both jacketed and non-jacketed tanks in various sizes. The jacketed tank provides an extra layer of insulation and helps to regulate the temperature. If you are looking for something more cost effective, the non-jacketed tank is the perfect solution. It still comes in a variety of sizes and materials such as SS, Hastelloy, Inconel, Monel or carbon steel.
We also stock various types of reactor accessories like baffles, spargers, stirrers and gas control panels. These help to control pH, temperature, foaming and reaction speed. The baffle is designed for a specific operating condition while the sparger distributes gas well into the liquid solution. In gas-liquid reactions, the stirrer is a critical part of the setup that helps in better stirring of the liquid. All these accessories are ideally suited for different operating conditions and can be custom made.
Chemical Reactors
In the chemical industry, there are four types of reactors that can be used for various applications: batch reactors, continuous stirred-tank reactors (CSTRs), packed bed reactors (PBRs), and plug flow reactors (PFRs). Each type of reactor has its own advantages and disadvantages. Choosing the right chemical reactor for your specific application is a complex task. It is important to consider the process requirements, production capacity, and reaction parameters when selecting a reactor. You must also determine the material of construction and corrosion resistance required. buy reactors from surplusrecord.
Larger reactors may require manholes or access ports for inspection, cleaning and maintenance purposes. They can also be fitted with agitators, temperature probes, pH probes, and other instrumentation equipment. These components are crucial to the efficiency of a chemical reaction.
Most chemical reactions require a stirring mechanism. Most stirring systems are comprised of an electromotor, a gearbox, and a shaft seal. The electromotor provides the rotational motion that is transferred to the blades, which then stir the materials. The shaft seal prevents leakage between the shaft and the reaction container. The seal is usually made of PTFE, ceramic or Hastelloy. It is necessary to ensure the seal is a high-quality one, as any leaks can potentially impact the overall performance of the system. Moreover, the sealing material must be compatible with the reaction fluid’s operating conditions and corrosive characteristics.
Valves
There are several different valves that can be used in chemical reactors. These include butterfly valves, gate valves and ball valves. The type of valve that is best depends on the material being processed in the reactor. For example, softer materials like polyethene can be processed with gate valves while more rigid substances require butterfly valves.
Another type of valve that is popular for use in chemical reactors is a plunger valve. This is a type of valve that uses a constant spring force to hold the plunger closed against the bottom of the reactor. It is then opened by air pressure that is supplied through a second regulator. This allows for the automatic draining of liquids and solvents from the reactor.
Plug valves are also used frequently for many chemical reactions. They are a type of quarter-turn valve in which a plug with a cylindrical or conical body rotates inside a larger body to open, close or throttle flow. These are well suited for use with chemicals because they can be made of various materials that resist corrosion.
In addition to the various types of valves that can be used, there are other equipment and supplies that need to be included with a chemical reactor. This includes a variety of instrumentation to monitor and control the reaction online including thermometers, barometers, pressure gauges, level gauges, pH meters and concentration meters. A PLC program can then link these instruments with the appropriate inlet and outlet valves for online control of the reactor.
