Challenge	The Siam Cement Group (SCG), the second largest company in Thailand, sought to enhance its existing production capabilities by implementing innovative non-linear Advanced Process Control (APC) software. The focus of this project was on the downstream petrochemical production lines of Thai Polyethylene Co., Ltd. & Thai Polypropylene Co., Ltd. These facilities produce a wide range of polyethylene, polypropylene, and high-value added products. The challenge was to drive enterprise value and maximize return on assets with non-linear APC and enable engineers to gain proficiency and extend APC applications across multiple polyolefin manufacturing units.

About Customer	The Siam Cement Group (SCG) is the second largest company in Thailand, manufacturing and supplying a full range of petrochemical products: upstream, intermediate, and downstream petrochemicals. The focus of this project was on the downstream petrochemical production lines of Thai Polyethylene Co., Ltd. & Thai Polypropylene Co., Ltd. These facilities produce a wide range of polyethylene, polypropylene, and high-value added products. SCG sought to enhance existing production capabilities by implementing innovative non-linear APC software from AspenTech. Read More
Solution	A standardized APC design was applied to all major units to utilize a collaborative implementation scheme to maximize knowledge transfer and replicate success in future developments. The software suite included Aspen Non-linear Controller, Polymer Inferential Properties, Recipe Management, Process Sequencer, and APC Performance Monitoring. SCG staff was intimately involved during development and commissioning, enabling engineers to obtain the skills required to design, maintain, and modify the APC controller when a process changes or new products are developed.
