In recent weeks, we’ve successfully delivered three 100L Hastelloy C-276 reactors to clients in the pharmaceutical and new energy sectors—each tackling a unique challenge in highly corrosive chemical synthesis. These projects highlight a growing industry demand: how to achieve stable, high-yield reactions in extreme environments (e.g., concentrated hydrochloric acid, wet chlorine, fluorine-containing solvents) without compromising equipment safety or product purity.

In the fields of chemical engineering, pharmaceuticals, and new materials, highly corrosive reaction media (such as concentrated hydrochloric acid, mixed acids, and chloride-containing salt solutions) impose stringent requirements on the materials of reaction equipment. The 100L Hastelloy reactor introduced in this solution employs Hastelloy as the core material for the reactor vessel and integrates Siemens PLC automation control systems. This ensures long-term stable operation under highly corrosive conditions while achieving precise control of process parameters, traceability of production processes, and informatized data integration.

Design of Hastelloy Reactor Vessel
The effective volume of the reactor body in this equipment is 100L, constructed with Hastelloy, which significantly enhances corrosion resistance compared to commonly used 316L stainless steel. It is primarily designed for highly corrosive media that cannot be handled by stainless steel or non-metallic materials.

Siemens Intelligent Control System
The equipment adopts a Siemens PLC as the central control unit, paired with a Siemens explosion-proof touch screen as the human-machine interface, featuring on-site display and operation functions. Users can perform parameter setting, status monitoring, and equipment start-stop operations via the touch screen. The interface is intuitive and easy to master, while the control system integrates multiple intelligent functions, enabling fully automated control of the reaction process
Temperature control system linkage control: It can display and control the operating status of supporting temperature control equipment in real time, accurately adjust heating and cooling power, support multi-stage temperature program settings, and meet the temperature curve requirements of complex reactions.

Process formula editing: The system supports the function of process formula editing. Users can edit parameters such as mixing speed, temperature, time, and feeding sequence according to different product requirements, and write them as automated formulas that can be called up with one click. When changing production models, simply select the corresponding formula number, and the system will automatically load all parameters, eliminating the risk of human operation deviation and parameter omission.
Production Batch Management: Automatically record production data for each batch, including reaction time, temperature curve, stirring speed, operator information, etc. The data can be exported and archived for production traceability and process optimization.

Fault alarm and automatic diagnosis: The system monitors the real-time operation status of equipment. When abnormal situations such as overheating, overpressure, and motor overload occur, the PLC automatically triggers sound and light alarms, displays fault codes and processing suggestions, and facilitates quick troubleshooting.

RS485 communication function: The device comes standard with an RS485 communication interface, supports Modbus RTU protocol, and can communicate with the upper computer or DCS system to achieve remote monitoring and data transmission, facilitating centralized management in the workshop.

The equipment frame and external structural components are made of stainless steel material, which has good mechanical strength and corrosion resistance, and is suitable for complex environments such as clean, humid, and intermittent contact with acid and alkali splashes in laboratories and pilot workshops. The stainless steel shell is impact resistant, has no risk of coating peeling, is easy to wipe and clean, and can meet the hygiene requirements for equipment appearance in the fields of fine chemicals and pharmaceuticals.

Application scenarios and value realization
Applicable fields: synthesis of new energy battery materials, preparation of special catalysts, synthesis of pharmaceutical APIs, production of corrosive chemicals and other high demand scenarios.
Core values:
Reliability: Hastelloy alloy and explosion-proof design ensure the safety of high-risk processes and reduce equipment failure rates.
Efficiency improvement: Automated control and formula management reduce manual intervention and shorten batch switching time.
Intelligent management: Data traceability and remote monitoring assist in process optimization and quality control.

The 100L Hastelloy Reactor is designed with a Hastelloy body to meet the challenges of highly corrosive media. An intelligent control center is constructed using Siemens PLC and explosion-proof touch screen, and digital and traceable production is achieved through process formulation management, batch management, fault diagnosis, and RS485 communication functions. The stainless steel material of the entire machine meets the requirements of cleanliness and durability in the on-site environment, achieving unity in corrosion resistance, automation level, and data integration capability. It can provide a reliable, efficient, and intelligent equipment platform for research and production in highly corrosive systems.
