The attractively located site was not available for development until recently because the soil and water in the area were contaminated by solvents discharged from a nearby military electronics plant, creating a brownfield.
Experimental results were compared to in situ porewater data in the wetland to better understand the factors controlling daughter product distributions in a chlorinated solvent plume discharging to a freshwater tidal wetland at Aberdeen Proving Ground, Maryland.
The effect of solvent component on the discharge performance of lithium sulfur (Li/S) cell and the optimal composition of ternary electrolyte for the improved discharge performance of the cell have been investigated.
These conditions, combined with the discharge of solvent at elevated temperature following its trip through the hot equipment, would have created the potential for over-exposure.
The effects of cross-membrane solvent transport and self-discharge were also considered.
In this paper we examine the influence of various mixed-solvent electrolytes on the discharge capacity and charge discharge cycle life of coin-type lithium (Li) metal/amorphous (a-) V2O5 P2O5 (95:5 in molar ratio) cells.
Intercalation of PF6− anions with organic carbonate solvents revealed relatively better discharge capacities compared to its anionic counterparts and 0.5 M NaPF6/EC:EMC electrolyte was found to be the most promising mixture among them.
This allowed to point out the importance of the solvent solvation ability on the discharge capacity.
Understanding the solvent's role in the discharge process would conduce to choose appropriate electrolyte for nonaqueous Li O2 batteries.
Examples of important mass targets include minimum consumption of material utilities (solvents, water, etc)., minimum discharge of wastes, minimum purchase of fresh raw materials, minimum production of undesirable byproducts, and maximum sales of desirable products.
This simple procedure will be a useful tool for process engineers to design self-sustained solvent using networks with zero effluent discharge.
