Inertisation and protection
Inertisation or blanketing is the process of filling the headspace of a vessel or reactor in order to protect it from explosion, undesired product degradation or polymerisation when oxygen and moisture are present. The absence of oxygen and moisture is important in all kind of applications and industries, including the (petro)chemical industry, food and beverages and pharmaceutical processes.
The monitoring of the off-gas going to the flare has to be continuously monitored under changing process conditions and hydrocarbon load. An inert gas is added in case of oxygen excess. Reliability is key for these types of analyser as it concerns both safety and environmental protection!
Inertisation and N2 blanketing
Storage of a variety of products, including fruit juices, milk powder, active pharmaceutical ingredients (API) and chemical substances, requires oxygen monitoring of the headspace in the storage tanks to prevent oxidation or even explosion. A TDL analyser, which can be installed as a probe directly into the vessel, needs no sampling and sample-preconditioning which are often a source of trouble and require high maintenance.
