Control and supervision system acetylsalicylic acid production
Reliable Service
Description of the Solution
The client has and obsolete facility where most of the tasks are manually performed and the system supervisión and raw material loading to the reactors is carried out with a Visual Basic application on Windows 95 equipments.
Because of the high risk due to failure in equipments and posible human errors during production, it is strongly adviced to the client a complete update of the system under the following conditions:
- Control hardware update (redundant Siemens PLCs and SCADA are offered).
- Automatic/manual control of all the dispositives and signals from the plant through two SCADA clients minimising required actions on behalf of the personnel.
- Installation of a distributed periphery appropriate for the ATEX zone and deployment of the equipments in different buildings to ensure operation in case of emergency.
- Comply with the norm 21 CFR part 11 of the FDA to keep Data Integrity.
Split the start up in two phases to always have one of the two reactors in operation.
