Instrumentation & Control Systems for Chemical Plants

The instrumentation and control systems engineered by Changzhou Sanli Tech International Trade Co., Ltd. are a critical component of our turnkey plant delivery, ensuring that every facility we build is a model of safety, efficiency, and reliability. We design these systems to provide complete visibility and control over the entire production process, from raw material receiving to finished product storage. For a plant like a Polysulfone Plant, which involves high-temperature polymerization and solvent handling, our control system includes sophisticated safety interlocks to prevent hazardous conditions. We utilize a hierarchical control structure, with a plant-wide DCS that oversees the entire operation, integrated with independent SIS for critical safety functions. Our scope includes the provision of all instrumentation, from smart transmitters to control valves with advanced diagnostics, as well as the design of the electrical and control room layouts. We also provide comprehensive training to the client’s engineers and operators on the operation of the control system. Our project team ensures that all control systems are thoroughly tested, first through a factory acceptance test (FAT) and then through a site acceptance test (SAT), to guarantee their flawless operation. By delivering a world-class instrumentation and control system, we provide our clients with the ultimate tool to manage their chemical plant safely and efficiently throughout its entire operational life.
