Volcanism is commonly accepted as the cause of the Permian-Triassic extinction, also known as …

Operators of combustion equipment are tasked with removing acid gases and particulate. Traditionally, wet scrubbers were used to absorb the gases, but the problem with wet scrubbers is the resultant water pollution. The exception is the limestone gypsum process, which produces wallboard quality gypsum. However, even this process has some water pollution due to washing …
