Contained Charging for High Potency
Given the trend for ever increasing potency of pharmaceutical powders, project engineers are continually faced with the challenge of upgrading the containment of their charging process to a new or existing reactor.
As a pioneer of containment, Powder Systems Limited (PSL) has refined a complete range of contained vessel charging solutions that will protect both the operator and the product down to nanograms containment level.
Our glovebox isolators are suitable for charging slurry and powder into reactors and other vessels from small-scale synthesis to bulk production. Many aspects have to be taken in consideration prior to design the appropriate charging solution:
- Assessment of powder transfer method and powder handling characteristics
- Evaluation of materials handling including manual or mechanically assisted requirements
- Vessel isolation method
- Assessment of pressures or steam in place requirements
SlurryBox
PSL recently enhanced their SlurryBox to enable charging of highly potent slurry into reactors through pressured vessels. The SlurryBox can be used as a central dispensing and weighing station servicing numerous reactors within the manufacturing site.
The vessels are specifically built for high potent process with CIP spray ring to clean each nozzle and minimum product retention design. The powder is charged safely into the vessel from the SlurryBox, and then liquid is brought in through nozzles to create the slurry. This method presents less risk of contamination with high potent powder as the product is moved within the site in a liquid state. Finally, the slurry is directly transferred from the vessel into the reactor under pressure for a better flow control. This also avoids using valves which involve a more complexes cleaning procedure.
The facilities delivered last year also enables recovery of catalysts and carbon from the bag filter in a contained environment.
Multi-Drum Monocell
The multi-drum monocell is specifically engineered to charge a reactor from different size drums containing potent powder.
The monocell drum hoist is a pneumatic raise and lower system for multiple height adjustment with a 98 degree rotating actuator for a 50kg maximum lift. The docking ring seals the drum chamber to the monocell using inflatable seals. The operator can then safely open the back door and reach into the drum without effort. The enhanced ergonomics allows minimum manual handling from the operator.
The Multi-Drum Monocell achieves an OEL of less than 1 µg/m³ 8 hours Time Weighted Average (TWA).
