Case Studies
Coking
PAS300 DCS is applied across all sections of coking operations, including coal preparation, cokemaking, and coke dry quenching. Using a fully redundant architecture of control stations, networks, and operator stations, it performs data acquisition, process interlocking, and automatic regulation, achieving closed-loop control of processes such as coke ovens, coke dry quenching, and hydrogen production. It also integrates monitoring of environmental protection facilities, supporting long-term stable operation of the plant and achieving energy savings and environmental compliance.
Metallurgy
Based on the PAS300 system, we has created an integrated ultra-low emission solution for steel plants targeting waste gas and dust from sintering, cokemaking, and ironmaking processes. It provides real-time monitoring of environmental and process parameters throughout the entire process, enabling coordinated production and treatment, helping enterprises meet ultra-low emission standards while balancing efficiency improvement and pollutant reduction.
Coke Oven Gas to LNG
LNG production faces challenges such as difficult methanation control, high energy consumption in cryogenic liquefaction, and significant safety risks. Chuanyi has built an integrated automation solution covering sensing, control, and actuation. Leveraging high-accuracy instruments, DCS and SIS systems, and high-performance actuators, it achieves fully automatic control of each process, balancing safe and efficient operation while improving economic and environmental benefits.
Waste-to-Energy Plant
The integrated plant-wide project for Phases I, II, and III of a waste-to-energy plant covers grate, utilities, steam turbine, flue gas purification, leachate treatment, and dust collection units. As the automation system supplier, Chuanyi provides a plant-wide integrated control system comprising DCS, ACC, DEH, ETS, TSI, and ECS.
Lithium Hydroxide
A battery-grade lithium hydroxide project adopts the mature sulfuric acid-based ore lithium extraction process, with production focused on conversion roasting, acidification roasting, leaching, and lithium hydroxide units. The DCS covers four workshops, achieving full-process control of the roasting-leaching, lithium hydroxide, and finished product sections. As the project’s MAV, Chuanyi provides field instruments, DCS, and intelligent systems.
