Instrumentation & Control Systems for Chemical Plants

At Changzhou Sanli Tech International Trade Co., Ltd., we recognize that advanced instrumentation and control systems are the central nervous system of any modern chemical plant, enabling safe, efficient, and reliable operation. Our expertise in this critical area is integrated into every project, ensuring that our clients’ plants operate at peak performance. We design and implement comprehensive control architectures, from basic regulatory control to advanced process control (APC) and safety instrumented systems (SIS). For a complex plant like a POM (Polyformaldehyde) Plant, our control system is designed to manage multiple unit operations—from the synthesis of formaldehyde to the final polymer extrusion—with seamless coordination. We select and integrate high-quality instrumentation, including flow meters, pressure transmitters, temperature sensors, and analyzers, to provide accurate, real-time data to the operators. Our systems are built around a robust distributed control system (DCS) platform that provides a single, unified interface for plant operation. We also design and implement emergency shutdown (ESD) and fire and gas (F&G) systems to ensure the highest level of safety. By providing a fully integrated instrumentation and control system, we give our clients the tools they need to operate their plant safely, maintain consistent product quality, and optimize their processes for maximum efficiency and profitability.
