Cellulose separation in a pilot plant

The wrong cooking process or uneven chip impregnation can lead to lower pulp quality, reduced yield and higher production costs. Discovering these issues only after full-scale implementation can be both costly and time-consuming to rectify.

RISE has developed a range of innovative pilot methods, capable of simulating all commercial cooking processes and optimising both kraft and sulphite pulping. The utilisation of wood chip and liquor samples in the pilot digester facilitates the recreation of mill environments, thereby supporting biorefinery research.

Key benefits:

• Improved yield and process efficiency
• Cleaner and more sustainable production
• Digitalisation and simulation capabilities
• Optimised separation and purification

Flexible cooking process:

• Time & Temperature: Precise control for optimal cellulose yield
• Cooking Liquors: Adjustable concentrations and flow rates
• Batch & Continuous Cooking: Simulates industrial processes
• Large-Scale Testing: Handles up to 40 kg of wood chips

This advanced separation technology facilitates the efficient extraction of cellulose from a variety of wood species and chip sizes, thereby driving innovation in the pulp and biorefinery industries.

Real-time chip Impregnation pilot

Chip impregnation is important in all chemical pulping processes, whether the aim is to produce paper pulp or dissolving pulp. When cooking chemicals penetrate the wood chips evenly, the process becomes more efficient and the pulp quality more consistent. For mills looking to increase production or resolve process issues, optimising chip impregnation is a key step towards improved performance and profitability.
