Hello there
Currently we have a Client processing lignosulfonates for carbon black production. Client is seeking for means to stop long-lead complaints about nasty odor. Client considers those lignosulfates are a source of problem.
Currently we have some doubts:
Option 1 - Incineration
Measure: We can collect ventgas from lignosulfonates storage tanks and route it to an incinerator where the flue gas from the carbon black reactors is afterburned.
Doubts: Tanks are located far enough from incinerator and Client will get a long pipe with stagnant flow (clogging, corrosion, undetectable sucking of air). Flue gas will be able to backflow to vent pipe during "intake" breath of tanks (corrosion, clogging).
Option 2 - Absorbtion.
Measure: We can provide a water scrubber (packing or liquid-seal).
Doubts: Force circulation of water through packing and friquent replacing of water in scrubber (expenses). Spent water is a source of the odor (risk of fail).
Option 3 - Adsorbtion
Measure: We can provide an activated carbon filter.
Dounts: Activated carbon is prone to self-ignition (safety). It is hard to be controlled (reliability, human factor). Activated carbon is not be able to provide complete cleaning (risk of fail).
Option 4 - Dispersion
Measure: We can provide a new vent stack or to route ventgas to flue gas stack.
Doubts: Client has been receiving recurring complaints from up to 10 km away from tanks (risk of fail). It is hard to believe that those are a consequence of inadequate dispersion.
Option 5 - Inerting
Measure: We can provide inert gas pad or purging.
Doubts: Inerting will not prevent vaporizing of lignosulfonates as Client considers odor is a consequence of a fermentation (risk of fail). A possible source of nitrogen is located far enough therefore Client will get a long pipe with stagnant flow (corrosion, clogging, undetectable leacking of inert gas). Rather high cost of nitrogen (expenses).
Any thoughts, ideas, experience and documents concerning the issue are appreciated.
