Instrumentation & Control Systems for Chemical Plants

The instrumentation and control systems we provide at Changzhou Sanli Tech International Trade Co., Ltd. are meticulously designed to meet the specific demands of each chemical process, ensuring both operational excellence and inherent safety. Our approach is to integrate the control system with the process design from the very beginning, resulting in a plant that is easy to operate and maintain. For a plant in the Ethylene Industry, such as an EO (Ethylene Oxide) Plant where precise temperature and pressure control is critical for safety and selectivity, we implement a sophisticated control strategy that includes multiple layers of protection. We design the logic for the DCS, the SIS, and the burner management system (BMS) to work in harmony. Our scope includes the specification and supply of all field instruments, from simple on/off valves to complex analytical instruments for online product quality monitoring. We also provide the complete cabling, marshalling, and control room infrastructure. For a project like a skid-mounted modular plant, we pre-wire and pre-program all control systems at our fabrication facility, allowing for factory acceptance testing (FAT) that significantly reduces on-site commissioning time. By delivering a fully integrated and tested instrumentation & control system, we ensure that the plant is ready for safe and efficient operation from the moment of start-up.
