Use of new containment technology for the low-dust solids filling of carbon nanotubes

Bayer Technology Sercvices (BTS) was able to demonstrate competence in the area of low-dust solids filling at the world’s largest pilot plant for carbon nanotubes (CNTs) with a capacity of 200 tons per annum at CHEMPARK Leverkusen. BTS managed the project and was responsible for the planning, implementation and commissioning of the filling system of the pilot facility, which opened at the end of January 2010.

Carbon nanotubes belong to a new generation of products. The selection of a suitable dust-tight filling system suitable for packaging the finished products and tailored to a spectrum of low-cost disposable container types was a major challenge for the project engineers.   
Together with a plant builder, BTS conceived and designed a combined sealed system for the filling of carbon nanotubes. Starting from a comprehensive concept developed by BTS, the feasibility of various technological solutions available on the market from vendors was assessed and the project costs estimated. Besides the product properties and packaging requirements, a variety of parameters such as explosion protection and cleaning of the system had to be considered.

To ensure compliance with work safety regulations, a filling system that fills 1,000-liter big bags as well as 60- and 210-liter drums under hygienic conditions was designed, realized and successfully brought on stream. Two completely different filling systems were adapted to a bunker discharge system, taking into consideration the heights of the various containers. To ensure protection against contamination, innovative peel-film technology was used for filling the disposable containers. Specially coated polyurethane film hoses are welded onto the inlet nozzle of the big bag. This nozzle can be opened under controlled conditions in such a way that contamination is avoided almost entirely, then resealed after filling.

Workshop

Learn about new solutions for the low-dust handling of big bags in production at a free workshop hosted by Bayer Technology Services GmbH at the Steigenberger Hotel in Hamburg on June 15, 2010. In addition to technology-based solutions for satisfying a wide variety of requirements, you will also find out what is behind the assessment of inhalation hazards in the chemical industry. You will also be given examples of technical, organizational and personal protective measures.
