Production scheduling of a multi-grade PET resin plant
Computers & Chemical Engineering, 2010We 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.

Natural fiber composites with plant oil-based resin
Composites Science and Technology, 2004Abstract Vacuum-assisted resin transfer molding or resin vacuum infusion process was used to make composite panels out of plant oil-based resin [acrylated epoxidized soybean oil (AESO)] and natural fiber mats made of flax, cellulose, pulp and hemp.

Synthetic Ion-exchange Resins as a Medium for Plant Growth
Nature, 1963SEVERAL authors have examined the utilization of exchange resins as sources of plant nutrients1–5. The method generally used was to provide the required quantity of each nutrient in the exchanger phase without considering the resulting concentrations or ratios of these nutrients in the bulk solution.

Carbon isotope biogeochemistry of plant resins and derived hydrocarbons
Organic Geochemistry, 1998Abstract Hydrocarbons derived from plant resins are major components of some terrigenous oils and bitumens. These compounds are structurally distinct and this makes them useful biomarkers applicable in petroleum exploration as well as sources of biogeochemical information about palaeoenvironment and palaeobotany.

DNA Changes in Tissues Entrapped in Plant Resins (the Precursors of Amber)
Naturwissenschaften, 2000There have been many reports characterizing DNA from amber, which is a fossil version of plant resin. Here we report an investigation of the effects of plant resin (from Pseudotsuga menziesii) and drying conditions on the preservation of DNA in biological tissues.

A Follow-up Study of Workers at a Dye and Resin Manufacturing Plant
Journal of Occupational and Environmental Medicine, 1989A total of 2642 men employed at a dye and resin manufacturing plant in New Jersey were observed from the opening of the plant in 1952 through 1985, and their mortality rates were compared with the rates of United States white men. The workers' mortality experience was related to former employment at the Cincinnati Chemical Works, which had produced or ...

Resinous plants as an economic alternative to bioenergy plantations
Energy, 1985Abstract The resin-producing xerophytic species Grindelia camporum is an economical alternative for bioenergy plantations in arid lands. A hypothetical bioenergy farm consists of the land and agricultural facilities needed to grow, harvest and transport 272, 100 Mg of biomass to the central processing plant, where the plant material is extracted ...

A study on a combined process for the treatment of phenolic resin plant effluents
Journal of Hazardous Materials, 2009The removal of phenol and formaldehyde from phenolic resin plant effluents has been studied by using a combined process. In the first step, phenol was removed from effluent by solvent extraction. Special attention was paid to the effluent with a low content of phenol, which was treated by non-dispersive solvent extraction in hollow fibres. It was found

An Updated Mortality Study of Workers at a Dye and Resin Manufacturing Plant
Journal of Occupational and Environmental Medicine, 2000This investigation evaluated the mortality experience of workers at a dye and resin manufacturing plant in New Jersey. The retrospective follow-up study included 3266 workers employed for at least 6 months at the plant. Plant production areas were South Dyes, where anthraquinone dyes and intermediates were produced; North Dyes, where azo dyes and ...
