As pressure on the world's forests and the surrounding ecosystems increases due to unsustainable agriculture, the expansion of infrastructure and illegal logging, it is time to take an even more holistic approach to protect and support these important resources for generations to .
ABSTRACT Eh–pH diagrams of a CaSH2O system at different conditions were described with thermodynamic calculations to investigate the leaching of sulphur from desulphurisation slag. The influences of temperature, oxygen partial pressure and activity of the dissolved species on the hydrothermal leaching of sulphur were systematically studied. The results show that the .

One set was tested in distilled (DI) water in a pressure chamber at 100 F (38 C) for 1000 hours. The pressure of the chamber was maintained between 52 and 55 psig. In the second test, coated panels were immersed in DI water for 6 months. The DI water was at ambient temperature condition for the first week of exposure.

In the most general sense, portland cement is produced by heating sources of lime, iron, silica, and alumina to clinkering temperature (2,500 to 2,800 degrees Fahrenheit) in a rotating kiln, then grinding the clinker to a fine powder. The heating that occurs in the kiln transforms the raw materials into new chemical compounds.
Example: a hydraulic system has a flow rate and tube diameter to achieve Re=3,400 in normal service. Flushing requires a minimum of Re=4,080. The fluid velocity (V) should not be less than 2 to 3 m/sec. (106 ft./sec.) in any part of the flushing loop. This prevents settling of particles inside tubes and hoses.
