Case Study: Tesnit BA-C in Pharmaceutical Industry
Industry – Pharmaceutical & Fine Chemical Industries
Pharmaceutical companies and related fine chemical industries develop, manufacture and supply worldwide specialty chemicals, drug intermediates, and final active pharma ingredients.
The production of such chemicals calls upon the use of chemical engineering installations, chemical reactor vessels (photo), etc, necessitating the use of sealing elements and gaskets.
Application – Chemical Reactors
Example: Stainless Steel Reactors
Reactor Chemical Content:
– Reaction Medium: a variety of Solvents used Basic or Advanced Starting Chemicals (ex. ketones, esters, alcohols); Acids (ex. Sulphuric Acid, Acetic Acid); Bases (ex. Caustic Soda, Amines).
– Inert Atmospheric Gases (ex. nitrogen, argon); Generated Gases.
Reaction Conditions:
– Temperature: up to 70 °C
– Pressure: up to 1-2 bar
Problem description
Some current designs in-use of Compressed Asbestos Fiber (CAF) (banned in the EU) or Compressed Non-Asbestos Fiber (CNAF) based gaskets have a simple PTFE protective jacket which is in contact with the reactor flanges and its enclosed chemicals. However, these gaskets are prone to chemical attack and degradation within 5-8 operation days, necessitating thus their replacement.
Such poor gasket performance leads to frequent maintenance and extra shut-down production time resulting in increased overall production costs and lower production outcome.
