Industrial Capabilities
We perform our custom processing operations in our ISO 9001 and Platinum Ecovadis certified plants in France and United Kingdom.
Introduction
We offer custom processing of a wide range of high purity materials by complex multistep synthesis including filtration, drying, distillation or crystallization.
These materials can be powder or liquid across a large range of scales; from 1 to 100 tonnes for powders and up to multi kilotonnes for liquids.

Catalyst Regeneration
Seqens can give new life to your depleted catalyst.
SEQENS assets include plants with the capability to improve the strength and re-impregnate silica hydrogels and cogels, zeolites and other catalysts supports.
- Wash the silica and other catalyst supports with aqueous or organic solutions
- Add active metal precursors via incipient wetness impregnation
- Dry with hot air/ nitrogen or with a double cone drier
By dissolving the active precursor in an aqueous or organic solution the metal-containing solution is then added to a catalyst support. Capillary action draws the solution into the pores. The catalyst can then be dried to drive off the volatile components within the solution, depositing the metal on the catalyst surface.
Pilot Scale Laboratories
SEQENS R&D and process development teams provide support and expertise from lab to commercial scale operations (including production of validation quantities under strict conditions), relying on our versatile pilot unit with dedicated lab and scale-up workshop.
Kilolabs (1-15L) and pilot units (100L to 2800L) are available at our Seqens’lab research center, close to our R&D and chemical development departments.
For further industrial transfers, as close as possible to the industrial units, our plants also have Kilolab (1-20L) and Pilot 10 -200L enamel and stainless steel units, 50L (1.8m lining) and 100L (1.3m lining) distillers.
