ABSTRACT:
In fabricating a reverse osmosis spiral wound apparatus for the separation of organic fluid mixtures, especially for the separation of dewaxing solvents containing ketone from dewaxed oil by permeation through a permeable membrane such as pretreated regenerated cellulose or asymmetric polyimide a special epoxy adhesive formulation is used to form the membrane element edge seals which serve to define separate permeate zones and feed stream zones. This special adhesive formulation is characterized by having a relatively long pot life, (i.e. will not set too quickly) permitting it to be easily handled during application to the membrane edges in the course of element fabrication, as well as being flexible (trimable) and of proper viscosity.
