Wet gas Sulfuric Acid (WSA) process for kraft mills

The basic WSA process. In the WSA process, commercial-grade sulfuric acid is produced on-site from a mill's Concentrated Non-Condensable Gases (CNCGs) by combustion, catalytic conversion and condensation. More than 99.9% of the sulfur in CNCGs can be converted to concentrated sulfuric acid, if required. Sulfuric acid is generated in a mill by ...

Pulp mill - Wikipedia

A pulp mill is a manufacturing facility that converts wood chips or other plant fiber sources into a thick fiber board which can be shipped to a paper mill for further processing. Pulp can be manufactured using mechanical, semi-chemical, or fully chemical methods (kraft and sulfite processes). The finished product may be either bleached or non-bleached, depending on the customer requirements.

Sulphur Granules / Lumps – Beroil Energy

Sulfur granulation is a size enlargement process. Small sulphur seeds (undersized granules) are repeatedly coated with a liquid sulphur spray and cooled. With repeated application of liquid sulphur, the seed increases in volume and weight.

Pulping Process - an overview | ScienceDirect Topics

Sulfur compounds, such as hydrogen sulfide, dimethyl sulfide, and dimethyl disulfide, are famous for their pungent odor and very low odor thresholds. Pulp and paper mills usually do not have odor control devices, but emitted sulfur compounds can be reduced by process modifications and improved operating conditions.

Lignin Recovery and sulfuric acid production in a kraft ...

When sulfur is dumped in the form of recovery boiler fly ash, the amount of NaOH required a make-up chemical is high (up to 20-30% of the total cost of produced lignin). For this reason, it makes sense to combine the Lignin Recovery system with a Wet gas Sulfuric Acid (WSA) process (Figure 3).

A dynamic Na/S balance of a kraft pulp mill

Normally in softwood mills there is an excess of sulfur and low levels of sodium, compared to what the process requires. The unbalance is adjusted in different ways depending on the mill. In the future, the pulp mill will most likely produce other products than just pulp, which in turn might induce the introduction of new processes.
