Featured Project

NCG and Methanol Incineration System

Engineering the successful incineration of process streams while meeting EU BREF standards.

Due to production increases and stringent environmental requirements, a large European mill contacted Lundberg seeking an alternative solution to incinerate concentrated non-condensable gas (CNCG), dilute non-condensable gas (DNCG), and methanol. Lundberg’s extensive experience with NCG collection and incineration systems helped this mill successfully meet its objectives and fulfill government requirements.

Featured Project

High concentration sodium bisulfite production

Exceeding strict government emissions requirements.

Employing our high-efficiency sulfur burner, Lundberg designed a system that targeted high efficiency sulfur use (recovering over 99% of sulfur into sodium bisulfite solution) and consequently helped our customer exceed the strict emissions requirements of the Maryland Department of the Environment.
