    Thermo-oxidizer load preliminar sizing

    I've been tasked at doing a conceptual project of a thermo-oxidizer as a site-wide final hidrocarbons treatment. The question is about the contaminants flowrate to consider for preliminary sizing of the heating and exhausting units for budgeting purposes. I intend using Toluene to model this...

    Industrial processes for Ferrous Chloride oxidation to Ferric Chloride

    Hi George, This oxidation is part of a fungicide synthesis route. I'm inclined to think that Peroxide oxidation of Fe2+ is probable one of the best routes. It's well know mechanism with high yield (source on PubChem:"Reaction between Ferrous Iron and Peroxides. I. Reaction with Hydrogen Peroxide...

    Industrial processes for Ferrous Chloride oxidation to Ferric Chloride

    Dear colleagues, Short and straight to the point question: in your expertize or knowledge, what are the best consolidated industrial processes to oxidize Ferrous Chloride in HCl solution to Ferric Chloride at an average productivity range of 500-1000 kg/h? Long version: I'll have a chemical...

    Is sonic velocity measurement a good alternative for pH measurement ?

    Uptating the post: After some research and contact with vendors, i think it is possible to use it for the intended application. But...is not exactly "cheap". It costs roughly four times more than a pHmeter. It would only be justifiable in more specific applications, (high maintenance cost of...

    Is sonic velocity measurement a good alternative for pH measurement ?

    Latexman, For what i understood, it is not the sonic velocity of solutions. Its the velocity of sonic waves propagating through the solution. In theory, this propagation should be affected by slight changes in density and/or the compressibility of the fluid, wich are altered by concentration...

    Is sonic velocity measurement a good alternative for pH measurement ?

    I have a scrubbing system for Dimethylamine that employs HCl 33% for pH adjustement. The problem is, as you know, field pHmeters demand high maintenance and are very prone to failures. Besides, "being cheap" is definivelly not one of the things you could point in their favor. I found the sonic...
