Continuous Flow Micro-Reaction Technology "HZSS Body" | Make Chemical Pharmaceuticals More Efficient And Safer

In the chemical pharmaceutical industry, the traditional kettle production method is still the main one, which has disadvantages such as long auxiliary operation time, high labor intensity for workers, difficulty in independent control, and slow mass and heat transfer.

Traditional batch production is prone to uneven temperature and concentration, resulting in low yield and poor product quality stability between batches. Especially when dealing with high temperature, high pressure, strong exothermic reactions and flammable, explosive, toxic, and harmful raw materials or intermediates, the traditional batch reaction process has problems such as difficulty in precise control and great safety hazards.

Continuous flow micro-reaction technology provides a new approach and method to solve the shortcomings and defects of traditional kettle synthesis. This technology can realize multi-step continuous flow automated synthesis and manufacturing from raw materials to API and even preparations through series or parallel reactors, without external intervention in the middle.

Compared with traditional kettle production, microchannel continuous flow skid-mounted equipment has the following advantages:

Higher production efficiency: The microchannel continuous flow skid-mounted equipment adopts a continuous production method. Compared with the intermittent production method of traditional kettle production, it has higher production efficiency and can greatly shorten the production cycle.

Lower energy consumption: The microchannel continuous flow skid-mounted equipment uses microchannel technology to achieve efficient heat and mass transfer, thereby reducing energy consumption and waste generation.

Higher product quality: Microchannel continuous flow skid-mounted equipment can achieve precise temperature and pressure control.

Shenshi Technology's subsidiary Micro-Intelligence has been committed to the design, production and manufacturing of microchannel reactor core process modules, skids and core process equipment for many years. It provides customers with microchannel continuous flow skid-mounted equipment using a one-stop service of modular design + modular construction, which has the following advantages:

1. The delivery date is certain and short (3-4 months), saving a lot of time for customers' project construction;

2. Easy to move and install, and compatible with existing structures on the customer's site;

3. High integration, including automatic control system, SIS safety instrument system, automatic temperature control system and other facilities;

4. Off-site processing, short construction period, safer and more reliable quality.

Micro-Intelligence Project Case 1

Relying on its rich experience in continuous flow projects, Micro Intelligence independently designed and built a fully automatic continuous flow industrial skid-mounted platform for a pharmaceutical company based on its customized design according to the actual situation of the customer. During this period, it overcame many difficulties such as the epidemic and the coming of the Spring Festival. It only took three months from contract signing to equipment delivery, which greatly guaranteed the production needs of customers.

This microchannel continuous flow reaction system adopts a solution of combining a microchannel reactor with a tubular reactor, which solves the safety issues of dangerous chemical processes such as diazo azide and quenching. The system is equipped with a PLC control system to achieve fully automated operation. This device has a high degree of automation and a friendly control interface, which can realize automatic monitoring, control feedback, data collection, real-time alarm, etc. In addition, the PLC control system has high compatibility and can communicate with the user's DCS system, which is convenient for remote monitoring and operation, thereby greatly reducing the number of workers and labor intensity, while effectively reducing human errors, improving production efficiency, and ensuring product quality.
