Inertisation and blanketing - Eliminating gaseous emissions

SOL technology, products and services for inertisation are based on many years of experience in controlling the injection of inert gas into plants or a section thereof, to obtain the required concentration inside, in particular in relation to the residual content of one or more types of chemical.

An operation conceptually analogous to inertisation is blanketing: this differs from inertisation because normally blanketing requires a moderate, continuous flow of slightly pressurised inert gas. We speak of blanketing when the plant or plant section to be treated contains products in a liquid or solid phase, obviously in addition to inert gas, while inertisation normally refers to the operation carried out after evacuating the liquid, solid or gaseous products present.

Inertisation can be carried out on the basis of the characteristics of the plant and the operational possibilities available with continuous or discontinuous flows of inert gas: with InerSOL technology, with the same volume to be inertised and the same content of inert gas, it is possible to optimise process times and nitrogen consumption through a specific analysis of customer requirements. In continuous production cycles, once initial inertisation has been carried out, a suitable pressure of inert gas must be constantly maintained within the system, using special control systems and apparatus that make it possible to bleed off gas during tank loading phases and inject it during withdrawal phases.
