2019-1-9Inorganic fluorides. About 3 kg (6.5 lb) of metspar grade fluorite, added directly to the batch, are used for every metric ton of steel made. The fluoride ions from CaF 2 lower the melt''s temperature and viscosity (make the liquid runnier). The calcium content has a tangential benefit in removing sulfur and phosphorus, but other additives such as lime are still needed.

Emissions trading - Wikipedia

2019-1-9Emissions trading, or cap and trade, is a market-based approach to controlling pollution by providing economic incentives for achieving reductions in the emissions of pollutants.[1] In contrast to command-and-control environmental regulations such as best available technology (BAT) standards and government subsidies, cap and trade (

Recent advances in vapor intrusion site investigations

The standard conceptual model for vapor intrusion consists of i) partitioning from groundwater or soil into soil gas, ii) diffusion through the vadose zone from the source area to the immediate vicinity of the building and iii) advection and/or diffusion through the building foundation (USEPA, 2015a, Fig. 1).Once vapors have entered a building, the indoor air containing these vapors is usually
