Quarrying of Stones: Its Methods, Selection of Site,

Definition: Stones occur in the form of natural rock masses or layers on the surface. The process of extraction of suitable stones from their natural rock beds or layers is commonly called Quarrying of Stones.It differs from the mining of ores of metals in that whereas quarrying is an operation carried out entirely on the surface, mining involves digging below the ground, sometimes at Get price

Dust explosions: A threat to the process industries

2015/11/1The first reported dust explosion accident is possibly a flour explosion in Turin in 1785 (Eckhoff, 2003). Subsequently, dust explosions were gradually recognized as accidents capable of causing severe damage, stimulating research on the mechanisms of dust explosions and related safety measures to prevent them or to protect plant personnel.

Lessons Learned from Recent Process Safety Incidents —

The explosion occurred after the process had been shut down and ammonium nitrate solution was left in several vessels. Multiple factors contributed to the explosion, including strongly acidic conditions in the neutralizer, application of 200-psig steam to the neutralizer vessel, and lack of monitoring of the plant when the process was shut down with materials in the process vessels.

The Difference Between Deflagration and Detonation

2019/12/8Deflagration is an explosion in which the speed of burning is lower than the speed of sound in the surroundings. Everyday fire and most controlled explosions are examples of deflagration. The flame propagation velocity is less than 100 meters per second (usually much lower), and the overpressure is less than 0.5 bar. Get price

This process, rapid neutron capture by neutron-rich isotopes, became known as the r-process, whereas the s-process was named for its characteristic slow neutron capture. A table apportioning the heavy isotopes phenomenologically between s -process and r -process isotopes was published in 1957 in the B 2 FH review paper, [1] which named the r -process and outlined the physics that guides it.
