This white paper discusses highly acidic chemical process slurries and the use of continuous vacuum filtration technologies for filtration, cake washing and drying.
First, the basics and benefits of continuous vacuum filtration technologies are reviewed followed by case-studies. In this first process, the precipitated solids are in sulfuric acid slurry. The challenge is to process 2200 kg/hour of dry solids for filtration, counter-current washing and drying in a contained environment.
In this second process, the objective is to process precipitated solids in an hydrochloric acid slurry. The white paper concludes with a framework for vacuum technology selection and how this can be applied to other toxic and difficult chemical process filtrations.10/18/2016
Gaseous oxygen measurement with amperometric sensors is the most direct and easiest solution for oxidation and explosion protection.
Unwelcome oxygen Tank blanketing is the process of filling the headspace in storage vessels and reactors with an inert gas to prevent its contents from exploding, degrading or polymerizing and to protect equipment from corrosion. A blanketing system is normally designed such that it operates under higher than atmospheric pressures, therefore preventing outside air from entering the vessel. As oxygen and moisture in the air can be undesired in numerous processes and applications, blanketing is done in a wide range of industries, varying from (petro)chemical to food and beverage, pharmaceutical to pure water.01/06/2010
Organic cellulose and biomass filtration, washing and drying is very unpredictable and even minor differences in feedstock,washing or cake moisture requirements can require a different process solution. Both vacuum and pressure operations can provide equivalvent process results. On-site testing is required to determine the optimum filter selection.09/11/2009
Manufacturing a pure product can be critically important to the next steps in the manufacture of a powder-based product. As a result the removal of residual moisture and solvents from the crystallization, filtration and drying steps can be crucial to producing a stable product.06/28/2006
