Additives/Extracts

Graver Technologies adsorbent and filtration solutions ensures that additives and extracts for the manufacture of drug (medicinal) products are safe and free of contamination.

Effective Adsorbent and Filtration Technologies for Additives and Extracts

Substances or mixtures of substances used to manufacture drug (medicinal) products may be synthesized or extracted from naturally derived sources. These products often require the removal of reaction by-products, color bodies or deformable solids to produce high quality pharmaceuticals, cosmetics or other healthcare products that meet both consumer expectation and regulatory standards. Adsorbent technologies that provide rapid kinetics of fine particles with excellent filtration characteristics are often a critical part of the process. Subsequent to these processes, the capture of any downstream particles or the critical removal of microbial contamination are necessary prior to packaging or incorporation into the final product.

Frequenty Asked Questions

How often should gas turbine filters be replaced?

This depends on the environment and filter type; however, pre-filters are changed every 3–6 months, while final filters may bechanged once in a year or two. Monitoring pressure drop is key to determiningreplacement timing.

What factors affect the operating life of a gas turbine filter?

Here are some factors:

Ambient dustand pollution levels
Operatinghours and load
Pulse-cleaningfrequency, depending on the type
Humidity andmoisture
Filter mediaand design

How do I know when a filter needs to be changed?

Differential pressure across the filter is animportant aspect in this case. If it increases beyond the set threshold, thefilter may be clogged or need cleaning or replacement.

What is pressure drop and why does it matter?

Pressure drop is the resistance to airflow through afilter. A high-pressure drop reduces turbine efficiency and increases energycosts. Selecting low-resistance filters helps improve performance.
