FLUE GAS TREATMENT, a type of PROCESS PACKAGES.
Flue Gas Treatment are a type of Process Packages.
The filtration process packages in this subcategory are organized using a two-tier classification: they first distinguish between direct-fired and indirect-fired systems, and then they differentiate by the type of medium being heated. Separating systems by whether they heat a gas or a liquid acknowledges that each requires different temperature and pressure ranges and thus distinct construction skills, adding greater nuance to this classification.
Waste incineration and many other industrial processes generate flue gases that are extremely damaging to the environment because they can contain pollutants like heavy metals, dioxins, hydrofluoric acid, hydrochloric acid, and sulfur oxides. Since these flue gases need treatment, the most common removal methods rely on electrostatic precipitators, DeNOx systems and scrubbers, which explains the sequence used for the categories.
Polishing units that employ adsorbent or catalyst-based solutions are also part of this subcategory and are used to further refine treated gases.
