Liquefaction of coal cargoes - MS Amlin Consumer Website

1. Coal cargoes are not subject to Group A requirements if they have a particle size distribution such that: a. not more than 10% is less than 1 mm AND. b. not more than 50% is less than 10 mm. Cargoes exceeding either of these limits will not be exempt from Group A requirements. This differs from the equivalent size criteria for iron ore fines. 2.

Abstract Liquefaction can be direct, from the coal itself, or indirect, from synthesis gas (CO and H 2) obtained by gasification of the coal. Coal liquefaction incorporates both an increase in the H/C ratio and removal of heteroatoms (S, N, O) and inorganic oxides (ash).

Coal - Earth Resources

Coal. Victoria boasts a 430-billion tonne brown coal reserve which is a huge portion of the world's coal resources. In 2013-14, total production in Victoria amounted to 57.8 Mt (metric tonnes). Victoria's brown coal is typically low in ash, sulphur, heavy metals and nitrogen. This makes it very low in impurities by world standards.

Liquefaction - Utah Geological Survey

Liquefaction may occur when water-saturated sandy soils are subjected to earthquake ground shaking. When soil liquefies, it loses strength and behaves as a viscous liquid (like quicksand) rather than as a solid. This can cause buildings to sink into the ground or tilt, empty buried tanks to rise to the ground surface, slope failures, nearly ...
