This is not a problem in a kraft pulp mill for example, where this can be a source of makeup chemicals to the recovery cycle.Scrubbing with sodium sulfite solution it is possible to scrub sulfur dioxide by using a cold solution of sodium sulfite, this forms a sodium hydrogen sulfite solution.
3 a mill trial conducted in a pennsylvanian bleached kraft pulp mill has established that taml catalyst injected into an alkaline peroxide bleach tower can significantly lower color from the effluent stream promising a new, more cost effective, energy-saving approach for color remediation adding further evidence of the value and diverse.
Grinding mill for mercury sulfur reaction.As a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete stone crushing plant.
The recovered flue gas heat will go into the hot water system for the facility, freeing up steam to generate additional green electricity.The innovative aspect of this approach is the unique materials that can handle acidic condensate from the flue gas, which have never been installed in a canadian pulp mill.
The present invention describes a process and system of producing methanol from methanol condensates.In a preferred embodiment the condensates are biomethanol condensates from chemical pulp mills and various waste sources used to produce a purified biomethanol.Pulp condensates are rich in methanol and contain many other contaminants.
The pulsair pulp stock chest mixing process allows for 100 of the pulp stock to be quickly mixed and agitated at any liquid level and in any size tank or vessel.Our industrial pulp stock mixing systems are efficient at agitating the stock chest because the mixing begins at the bottom of the stock chest tank or vessel.
