CELLULOSE PROCESSING INDUSTRY

GREAT PERFORMANCE
THAT GOES UNNOTICED

The process from organic raw materials
to tasty products is supported
by biological emission solutions.
Green is the future.

_GREAT PERFORMANCE THAT GOES UNNOTICED

The conventional way to reduce emissions in this industry is by installing thermal oxidizers, often in combination with chemical scrubbers, or by installing large carbon beds. Investment is high, as are the operating costs, caused by increasing energy costs, carbon replacement, demanding maintenance and by having to add chemicals. The corrosive reaction of sulfur has its own impressive impact on OPEX.

Taking into account the hazardous and explosive characteristics of CS2 and knowing the risks involved in operating these installations, many HE&S Managers and Plant Operators are looking for alternative, yet reliable, solutions. If you are too, and if cost savings are high on your agenda as well, you want to consider Azzuro’s technology.

The biological process that takes place within Azzuro’s high-performance bioreactor contains a very large and robust population of selected bacteria operating at ambient temperature and pressure. The bacteria are retained using a unique and patented immobilization technology to ensure the growth of a uniformly porous bacterial sponge through which a sulfur-rich gas stream flows with small amounts of water added to the process.

Natural bacterial metabolism efficiently oxidizes sulfur, producing clean effluent air and sulfuric acid. The acid might be re-used for various purposes in the manufacturing process or, alternatively, can be neutralized using inexpensive industrial lime, and then discharged.

Minimal requirements for this natural biological process include only airflow, moisture, and small amounts of added nutrients, all of which are reliably maintained by the bioreactor’s control system.
