The Geel plant of Janssen Pharmaceutica is a chemical synthesis plant which makes primary API's. This is done through use of an extensive number of solvents. In order to load the batch reactors with the right quantity of solvent, there was a need for highly precise mass flow meters. Even though this customer had no experience with RotaMASS, we succeeded in selling 18 pieces.
Janssen Pharmaceutica is part of Johnson & Johnson, the largest company in the world in the field of healthcare. The company has three facilities in Belgium. The facility in Geel is known for the production of active substances (called API or Active Pharmaceutical Ingredients) for the medicines that are manufactured in the facility in Beerse. The facility in Olen only provides quality research.
Four production plants
The facility in Geel has four production plants in which various multipurpose plants.
The process generally consists of the following components:
For the final products, the story hasn't finished yet. In order to be able to measure these powders correctly and add them to medicines in small quantities they have to have the right consistency and grain size. To that end, the facility in Geel has a separate department, the powder unit, where the active substances are ground and sifted.
Yokogawa RotaMASS
A Yokogawa RotaMASS is used to precisely measure the recuperated solvents that are pumped from the tanks to the various reactors. RotaMASS is a mass flow meter based on the Coriolis effect.
The reasons why a Coriolis mass flow meter was chosen speak for themselves:
•Working with weight measurements and/or differential pressure transmitters for extremely accurate measurements, from tanks of 10,000 up to 16,000l with a product density variation of between 0.7 kg/l and 1.5 kg/l, is very difficult.
•The customer recognized the following advantages: reliability, accuracy, guaranteed draining system, easily cleaned system, no moving parts, directly built into the pipelines, low pressure losses.
The advantages of Yokogawa on top of the arguments mentioned above were:
RotaMASS
In the meantime, the meters have already been operating for several months to the great satisfaction of the users.

ROTAMASS is the integral and remote type Coriolis Mass Flow Meter. Both types have highly refined digital signal processing electronics, so that accurate and stable mass flow measurement is achieved.
The Variable Area Flowmeter is one of the oldest and mature principles in flow measurement with its simple design: a float rises inside a conically shaped glass tube as the flow increases and its position on a scale can be read off as the flow rate. Since this measuring method is purely mechanic, it as simple as it is reliable.
