Flavors and fragrances

We have worked on a wide range of streams and by-products from these industry sectors for recovery/toll recovery. Many projects are for repeat customers and we continue to build on relationships we create to offer improved value for our customers.

Selling ethics for recovered solvents

When reselling our recovered solvents, we ensure that duty of care is taken into account and we are very aware of the ethics of using recovered solvents in relation to the industry in which the solvents are then used. We therefore sell the products to our customers on the following understanding.

This product comprises recovered material and should not be used for any tobacco products, medical devices, food, animal or pharmaceutical applications. The buyer shall ensure any onward sale of product or formulation containing product shall be similarly described. By accepting the order, the buyer agrees to these conditions. The buyer is aware that this is a recovered product and takes all responsibility for any claims arising from any onwards sale of the product.

SEQENS can help you reduce costs and waste by regenerating waste solvent streams. Monoethylene Glycol(MEG) & Methanol are widely used in the oil & gas industry to inhibit hydrate formation and prevent pipeline corrosion. To ensure effective operation, there is often a need for the continual injection of MEG or methanol. To reduce both operating and waste costs, SEQENS can offer to regenerate the resultant contaminated stream. The material is processed by us, onshore, and recovered to a purity suitable for recycling back to your process. Our dehydration unit removes water and salt from the material to meet your specification.
