Alkoxylation Complete Set of Equipment

Alkoxylation products are important chemical intermediates and fine chemical products in industrial applications, serving as indispensable high‑tech materials in today’s world. The alkoxylation reactors manufactured by Shanghai Yanzheng are also known as ethoxylation units, propoxylation units, EO/PO polyether units, polyether reaction units, and alkylation reaction units. These reactors are small-scale experimental units for polyether production based on EO/PO as the primary raw materials, and they operate as batch reactors.

Ethylene Slurry and Propylene Liquid-Phase Bulk Polymerization Unit

Ethylene slurry and propylene liquid-phase bulk polymerization units are industrial equipment used to produce polymeric materials. These units typically comprise reaction vessels, heating systems, agitation devices, feed units, vacuum systems, and purging units, among other components. They can carry out continuous reactions under high-temperature and high-pressure conditions, making them suitable for producing high‑quality polymeric products. Ethylene slurry and propylene liquid-phase bulk polymerization units are primarily used in fields such as healthcare, environmental protection, food processing, chemical engineering, and biotechnology. Through these units, ethylene and propylene can undergo polymerization reactions to produce high‑density polyethylene (HDPE) and other polymeric materials.

Ethylene Polymerization Evaluation Unit

The ethylene polymerization evaluation unit is laboratory equipment used to study and assess ethylene polymerization processes. It typically includes a reactor for carrying out ethylene polymerization reactions, as well as supporting systems such as heating, cooling, stirring, and pressure control. These units can simulate industrial production conditions, helping researchers optimize polymerization processes and improve product quality and production efficiency.

Small-scale experimental polyester reactor

The pilot-scale polyester reactor is a piece of equipment specifically designed for laboratory‑scale polyester synthesis research. It typically features a small capacity and can simulate the polymerization reaction conditions found in industrial production processes, enabling researchers to conduct small‑scale experiments and studies. These reactors are usually equipped with precise temperature control systems, stirring devices, and essential safety measures to ensure smooth experimentation and personnel safety.

Microbubble Fixed Bed

Microbubble process intensification in fixed beds is a technological approach with significant applications in fields such as chemical engineering and environmental science. By employing specialized equipment or methods, gas is dispersed into tiny bubbles, typically on the micrometer scale. These microbubbles possess a large specific surface area, providing an increased gas–liquid interfacial area. This dramatically enhances gas–liquid mass transfer efficiency; for processes that are mass-transfer–limited—such as gas absorption and liquid-phase oxidation—it can significantly accelerate reaction rates and improve production efficiency. Moreover, due to the enhanced mass transfer efficiency, the volume of fixed bed required for processing the same amount of material is relatively small, resulting in a compact footprint for the equipment and facilitating plant layout and construction.

Polyester Polymerization Reactor

The polyester polymerization reactor is a reaction vessel used for synthesizing polymeric compounds. It primarily involves two key steps: esterification and polycondensation. Esterification refers to the reaction between alcohols and carboxylic acids or inorganic oxygen‑containing acids, which occurs under specific temperature and pressure conditions to produce esters and water. Polycondensation, on the other hand, is a reaction in which one or more monomers undergo condensation to form polymers, with the main product being known as a polycondensate. During this process, the alcohol produced by the reaction is discharged from the reactor and collected via condensation, ultimately yielding the polycondensation product within the reactor.

Automated Reactor

The fully automatic stirred-bed reactor test setup is a critical component in the high‑throughput stirred‑bed evaluation of catalysts within the intelligent hydrothermal synthesis material preparation system. It serves as the pivotal link connecting front‑end catalyst synthesis with back‑end analysis and testing, with a primary focus on efficiently enhancing the fully automated evaluation of catalysts and the experimentation of process parameters, thereby improving the efficiency of catalyst evaluation in stirred‑bed processes.

Fully Automatic Hydrogenation Instrument

Fully automatic hydrogenation system, designed for a maximum temperature of 500°C and a maximum pressure of 20 MPa. The feed system is equipped with a weight‑based closed‑loop control module to optimize and ensure precise high‑pressure HPLC sample delivery. The system’s total volume is less than 100 ml, enabling safe hydrogenation. The discharge section features a 1 ml quantitative loop for collecting fresh samples, while the gas–liquid separation volume module is designed to be less than 10 ml. Coupled with an automatic drain valve, this configuration achieves pressure‑stable, high‑pressure automated discharge without pressure fluctuations. The system’s pressure is automatically controlled, and the entire system is equipped with sequential control workflow software, enabling fully automated process operation around the clock with no human supervision.

Fully Automatic Fischer–Tropsch Synthesis Apparatus

The fully automatic fixed-bed reactor operates at a temperature range of RT–1000℃ for gas‑phase reactions with 6 gases and 2 liquids, employing a process control system (sequence control). It is constructed from quartz and 316L 625 reactor materials, with the entire system undergoing passivation treatment. Three-stage condensation ensures automatic discharge of condensates (wax, water, gasoline) without pressure fluctuations, while pressure is automatically controlled. The system features robust safety protection mechanisms at the hardware level, including safety relief valves, to ensure safe operation even in the event of emergencies such as power outages or gas supply interruptions.

Scalable Agitated Baffle Reactor

The Scalable Agitated Baffle Reactor is a scalable stirred baffle reactor capable of performing continuous stirred-tank reactors (CSTRs). The scalable agitated baffle reactor is ideal for laboratory use within flow chemistry technology platforms—it’s a scalable stirred baffle reactor designed for continuous stirred-tank operation (CSTR). It can be used for continuous reactions involving liquids, gases, and solids, and is widely applied in fields such as fragrances, food supplements, cosmetics, and pharmaceutical intermediates. By combining the advantages of batch reactors and continuous flow reactors, it is suitable for a wide range of applications and can be easily scaled up. With its high performance, it delivers superior product quality, accelerates development timelines, and boosts production output.
