AI Overview
Automatic control in industrial sulphonation processes (used for manufacturing surfactants like LAS and SLES) is crucial for managing highly exothermic reactions, ensuring product quality, and maintaining safety. Modern plants utilize fully automated Programmable Logic Controller (PLC) and Distributed Control System (DCS) setups to monitor and adjust key parameters in real-time, often minimizing operator interaction.
Key Aspects of Sulphonation Automatic Control:
- Process Parameter Control: Automatic systems manage the precise molar ratio of sulfur trioxide () to organic feed, controlling the degree of sulfonation and minimizing side reactions.
- Temperature Management: Advanced cooling systems, such as in Multitube Falling Film Reactors (MTFR), independently manage temperature across multiple cooling zones, responding to PLC logic to maintain optimal reaction temperatures.
- Feed Control: Automatic systems control the flow of reactants, such as using frequency converters on organic feed pumps to match the required flow based on gas density.
- Automatic Shutdown/Safety: Automated systems include safety interlocks for emergency shutdowns (e.g., if cooling fails or pressures exceed limits).
- Instrumentation: Key sensors used include mass flow meters (Emerson), dew point meters (Michelle), pH meters (Mettler Toledo), and various transmitters (Yokogawa).
Common Automated Technologies:
- Ballestra SULPHONEXT Reactors: Utilize automated technology for superior heat transfer and energy efficiency in detergent surfactant production.
- Marsina Engineering Systems: Feature fully automatic PLC control for sulfonating LAB, fatty alcohols, and SLES production, including multi-stage de-dioxanization units.
- Nanjing Qino A.C.E. Systems: Utilize PLC controls for managing continuous falling film sulfonation reactors.
These control systems are generally built by international automation brands, including Siemens, ABB, Supcon, Hollysys, and Honeywell.
