Custom processing is Seqens Advanced specialties’ core activity

We are at our best when we can combine our versatile reactors with our excellent distillation capabilities whilst our solvent recovery service can further improve our efficiency by adding increased value to by-product or recycle streams. We are based at two sites in the UK and our range of equipment includes:

  • 9 glass lined and stainless steel reactors from 9 m³ to 25 m³ with reaction temperatures to 230°C
  • 9 distillation units with up to 50 theoretical stages and vacuum capability to 5 mm Hg
  • Wide range of feed and side stream options
  • Solid raw material addition
  • Bulk methyl chloride and other difficult to handle raw materials

With the versatility of our units, we are ideally placed to offer you the right option from start up, through the growth phase and any sudden increases in demand, to mature quantities by our ability to flex the capacity we can make available for your product. Our highly successful track record is based on delivering a global service that provides:
