At the heart of the new Hostalen Advanced Cascade Process (Hostalen ACP) technology are three reactors in cascade, enabling the production of multimodal HDPE resins. Extension of the well-proven, highly regarded Hostalen bimodal process technology to multimodal capability marks another significant milestone in LyondellBasell’s rich history of innovation.
Hostalen ACP process technology manufactures high-performance, multimodal HDPE resins with an industry-leading stiffness/toughness balance, impact resistance, high stress cracking resistance and processing advantages used in film, blow molding and pipe applications.
The success of the technology is reflected in the one million tons of Hostalen ACP capacity in production annually at the company’s wholly-owned and joint venture locations:
- Basell Polyolefine GmbH, Wesseling, Germany – 320 KT per year, start-up 2004
- Basell Orlen Polyolefins SP. z o.o., Plock, Poland – 320 KT per year, start-up 2005
- Saudi Ethylene & Polyethylene Company, Al-Jubail Industrial City, Saudi Arabia – 400 KT per year, start-up March 2009
- Basell Polyolefine GmbH, Münchsmünster, Germany – 250 KT per year, start-up 2010
Technology highlights
- Slurry cascade process with three stirred polymerization reactors in series
- Customized molecular weight distribution design and composition of the final products
- Polymerization conditions can be adjusted independently for each reactor
Design and reliability
- Developed from the leading Hostalen bimodal process technology with demonstrated high reliability
- Single catalyst family of Zielger catalysts, enabling a simpler operation
- Commercially proven at plant capacities of up to 400 KT per year
- Hostalen bimodal process can be expanded to Hostalen ACP technology
