Petrochemical and fine chemical production involves explosive gas atmospheres, corrosive process media and strict requirements for process control accuracy and production safety. Our solution complies with international intrinsic safety explosion protection standards.
- Intrinsic safety interface protection: Isolated intrinsic safety barriers are installed on the control room side to strictly limit the electrical energy delivered to field hazardous areas below the ignition threshold of explosive mixtures, complying with IECEx standards for Zone 0/1/2 explosive gas environments. They also provide triple galvanic isolation to eliminate ground loop interference and protect control system hardware.
- High-precision process control: DCS control cabinets paired with intelligent valve positioners, pressure transmitters and temperature transmitters realize high-precision closed-loop regulation of reactor temperature, pressure and feed flow. The system supports full process data recording, trend analysis and fault alarm functions, improving production consistency and operational safety.
- Reliable on-site power distribution: Medium-voltage ring main units and corrosion-resistant distribution equipment provide stable power supply for production areas. Wetted parts of field instruments can be configured with 316L stainless steel or PTFE lining to adapt to corrosive chemical media.
This solution is widely used in oil refining, pesticide production, pharmaceutical intermediate and fine chemical projects, balancing high control accuracy and essential production safety.
