The plant began production in January 1945, and was closed in October of the same year. The gunpowder being produced at the plant was being used for navy artillery shells. The smokestacks were for boiling water that was used to manufacture the gunpowder. The large T-Walls were part of solvent recovery houses.
The Alcohol Pulping and Recovery (APR) process treats wood in 3 stages, each using increasingly cleaner solvent. The important process parameters are extraction time, temperature, solvent composition and pH. Pilot plant operation has shown that ethanol pulping produces pulp superior to sulphite pulp at a lower cost.
By the time ICI closed the plant it had a capacity of 100,000 tons per year. [22] In 1975 a company called Solrec Limited (Solrec is abbreviated from solvent recovery) purchased part of the refinery site. [4] The company processed and recycled waste materials. Steam distillation was used to recover solvents.
The plant was used for solvent recovery operations from waste chemicals. Operations ended in 1979, and ownership of the site was retained by Honeywell. Some of the chemical operations had contaminated adjacent soils, groundwater and waterways in the New Jersey Meadowlands .
Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials. [1] [2] Processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy, and molten salt electrometallurgy. Hydrometallurgy is typically divided into three general areas: Leaching
Wastewater from metal mines and ore recovery plants are inevitably contaminated by the minerals present in the native rock formations. Following crushing and extraction of the desirable materials, undesirable materials may enter the wastewater stream. For metal mines, this can include unwanted metals such as zinc and other materials such as ...
The majority of seawater deaeration plants supplied by Eta use vacuum stripping. [91] Koch Modular Process Systems specializes in modular mass transfer systems. Typical applications for these systems include chemical purification, solvent recovery, and liquid-liquid extraction. Koch Modular Process Systems also runs a state-of-the-art pilot ...
PUREX is the de facto standard aqueous nuclear reprocessing method for the recovery of uranium and plutonium from used nuclear fuel (spent nuclear fuel, or irradiated nuclear fuel). It is based on liquid–liquid extraction ion-exchange. [8]
