Hydrofluoric acid is an irritant to the mucosa of the upper and lower portions of the respiratory tract. As in ocular tissues, concentrations as low as 5 mg/L (5 ppm) may produce irritation to the nasal mucosa. When hydrofluoric acid is present in concentrations greater than 48%, the solution fumes, adding to the volatile airborne fraction.
A plant normally operated to take all or part of the minimum continuous load of a system, and which consequently produces electricity at an essentially constant rate. A base load plant typically has relatively high fixed costs and low unit operating costs. Traditionally, nuclear plants have been considered as base load plants.
2018-12-12 · This critical review examines recent scientific and patent literature in the appliion of microwave reactors for alytic transformation of biomass and biomass-derived molecules with a particular emphasis on heterogeneous alysis. Several recent reports highlight dramatic reductions in reaction time and even superior selectivity when microwaves are used.
