Creating an inert atmosphere for tank cleaning
Result1. Nitrogen Evaporator. A comparably easy way of creating an inert atmosphere is to use nitrogen. Nitrogen is delivered as a liquid and turned into gas (evaporated) on-site while being entered into a tank. This is generally seen as the easiest inertion method, but local conditions can occasionally make rental of the …

Thermal Properties of Sulfur
ResultSulfur – Thermal Conductivity. Thermal conductivity of Sulfur is 0.269 W/ (m·K). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It is a measure of a substance's ability to transfer heat through a material by conduction.

ResultInert atmosphere. The source of the inert atmosphere is usually a cylinder of nitrogen or argon gas under pressure, which should be placed as close to the apparatus as possible to avoid long 'runs' of connecting rubber tubing. The gas flow rate from the cylinder is controlled by the cylinder head regulating valve (Fig. 18.1).
