On the other hand, performance of the baghouse is not sensitive to the sulfur content of the coal.
There are, however, few studies about the effect of backwash on sulfur packed-bed reactors.
This classification is based on the sulfur content because this is the element that makes a fuel more or less contaminating.
The precipitated metals can subsequently be involved in reactions of the sulfur cycle.
In 1979, an air quality standard for sulfur dioxide was established.
However, we find unexpected complexity in the sulfur cycle in a chemoautotrophically-based cave ecosystem.
Sodium and sulfur are very soluble, and therefore mobile, while calcium is less soluble and mobile.
They contribute 16 per cent of all particulate matter pollution, and 43 per cent of all sulfur dioxide.
