Pilot plant separation system BTPX 305 The key to success in bridging the gap from the laboratory to commercial production is a pilot plant that delivers results that will be relevant when you move into full-scale production. Scaling-up involves compromises that often cannot be predicted in the laboratory. Alfa Laval solves this problem with the versatile BTPX 305 centrifuge. Suitable for feedrates up to 2 000 litres per hour, the BTPX 305 can be delivered in a multitude of configurations and it is therefore adaptable to almost any duty and appplication imaginable. For hazardous duties the centrifuge complies with ATEX requirements for zone 1 or 2 and a skid mounted separation system can be designed for inert gas purging, thus insuring the highest level of safety. For biological hazards the separation system can be designed for steam sterilization and contained operation, which meets the requirements of the NIH guidelines for BLS 2. Furthermore, Alfa Laval´s experience in hygienic equipment design and GMP manufacturing ensure the integrity of valuable biopharmaceuticals. Applications The BTPX 305 is a solids-ejecting centrifuge in clarifier, purifier and concentrator execution, equipped with a well-proven, reliable fixed partial solids discharge, which can be initiated by timer, turbidity and/or totalised flowrate. In the clarifier execution the centrifuge is used for removing suspended solids from a liquid, while in the purifier and concentrator execution it is used for removing suspended solids, while separating two intermixed and immiscible liquid phases of different densities. The solids content in the feed is normally in the range of 0.1 – 10% by volume, but can vary between different duties. Complete separation systems Alfa Laval has over a hundred years experience in the design and supply of separation equipment. Complete systems, customized for specific applications, can be provided in a compact, fully tested, skid-mounted assembly. For process flow equipment, such as valves and instruments as well as control systems, Alfa Laval use only leading subsuppliers. Many options are available and we are willing to discuss specific requirements. Typical example of a BTPX 305 separation system for steam sterilization and contained operation.

Standard centrifuge design The centrifuge consists of a frame that has a horizontal drive shaft, worm gear, lubricating oil bath and vertical bowl spindle in the lower part. The bowl is mounted on top of the spindle, inside the space formed by the upper part of the frame, the ring solids cover, the collecting cover, and the frame hood. The liquid discharge system also rests on this structure. All parts in contact with the process liquid are made of stainless steel. The bowl is of the solids-ejecting disc type with an automatic hydraulic operating system for discharging. It is a so called timer...
