Resin plant considerations

Pigment & Resin Technology, 1983
The resin plant user and designer have a joint responsibility to provide reliable process plants, conserve energy and maintain the highest degree of safety. With this in mind Hygrotherm for many years has been designing and building resin plants for installation world‐wide. They have covered a wide range of products and operating conditions.

Production scheduling of a multi-grade PET resin plant

Computers & Chemical Engineering, 2010
We present a discrete-time, Mixed Integer Linear Programming (MILP) model for the production scheduling of a continuous-process multi-grade PET resin plant. The objective is to minimize the cost associated with grade changeovers in order to avoid undesirable variations in base resin properties and process conditions that occur during such changes.

Process computer applications in resin plants

IFAC Proceedings Volumes, 1977
In the chemical industry many resin-type products are manufactured discontinuously in batch reactors. Besides closed loop control of such process variables as temperature and pressure a main control reauirement is time- and event-dependent on-off control through the the sequential processing stapes, fuch processes were formerly controlled using ...

Separation of plant polyphenolics by chromatography on a boronate resin

Journal of Chromatography A, 1981
m-Aminophenylboronic acid attached to polyacrylamide beads by a short aliphatic chain strongly and selectively binds vicinal dihydroxyphenyl substituted compounds at pH 7–8. At lower pH these substances are released quantitatively thus affording a simple and rapid method for separation and purification of catecholic materials.

Resin plant safety: The designer's contribution and conscience

Pigment & Resin Technology, 1977
Ultimate process plant safety is both most vulnerable and most easily attainable at the design stage. Asked bluntly: “Do you want a safe plant or a dangerous one?” nobody would choose danger but the question is rarely put as simply as that. Considerations of cost cloud the basic issues.
