Alcan Achieves Early Start Up with AMS
Alcan had a tight schedule to expand its bauxite to alumina mineral processing refinery from 2.2 to 3.8 million tons. Alcan’s challenge included balancing the capital cost, minimizing the number of construction personnel on-site, integrate the green-field and brown-field facilities without affecting current operating facilities whilst achieving project budget, schedule and quality.

Alcan decided to expand using a Pre-Assembled Module (PAM) concept which enabled all modules to be built offsite in Thailand and Vietnam. By using Emerson's DeltaV and AMS Device Manager to pre-commission FOUNDATION fieldbus devices, Alcan significantly reduced man-hours and experienced cost savings.

- USE CASES
Process Control & OptimizationProcess control and optimization (PCO) is the discipline of adjusting a process to maintain or optimize a specified set of parameters without violating process constraints. The PCO market is being driven by rising demand for energy-efficient production processes, safety and security concerns, and the development of IoT systems that can reliably predict process deviations. Fundamentally, there are three parameters that can be adjusted to affect optimal performance. - Equipment optimization: The first step is to verify that the existing equipment is being used to its fullest advantage by examining operating data to identify equipment bottlenecks. - Operating procedures: Operating procedures may vary widely from person-to-person or from shift-to-shift. Automation of the plant can help significantly. But automation will be of no help if the operators take control and run the plant in manual. - Control optimization: In a typical processing plant, such as a chemical plant or oil refinery, there are hundreds or even thousands of control loops. Each control loop is responsible for controlling one part of the process, such as maintaining a temperature, level, or flow. If the control loop is not properly designed and tuned, the process runs below its optimum. The process will be more expensive to operate, and equipment will wear out prematurely. For each control loop to run optimally, identification of sensor, valve, and tuning problems is important. It has been well documented that over 35% of control loops typically have problems. The process of continuously monitoring and optimizing the entire plant is sometimes called performance supervision.
