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

Solid-liquid separation is an instrumental part of chemical processing. To separate the solid particles, filter media made of textile or metallic materials and of composite materials are used as the basis for the filter cake. Often there will also be a washing process to improve the purity of the filter cake or to increase the yield of the liquid phase. Solid-liquid separation can be carried out in continuous or batch operation. There are many factors for selecting the right process filtration system for your specific application. This white paper reviews methods for identifying the right process filtration technology for your application and highlights case studies illustrating the methods discussed.02/25/2014
For chemical processors, changing process conditions demand quick responses in order to keep processing effective and to keep processes running properly. For processes undergoing such changes, accurate and timely measurements, such as vibration monitoring, redundant tank level measurement and steam header temperature profiling can be difficult to collect. In well-established plants it’s both very expensive and time consuming to get measurement points online using conventional wired instrumentation. Many processors are now turning to wireless devices that can supply data from numerous points that never could have been justified otherwise. In this Chemical Processing Wireless eHandbook we take a look at wireless technology solution successes:
** How installing a wireless pH analyzer for crucial insights on seal integrity provided Fuji Film with a low-cost monitoring solution for protecting a pricey pump
** How one of the world’s largest producers of chlorine, caustic soda and vinyl chloride embraced wireless technology and achieved operating economies and more efficient control of its chemical processes

It's a classic scenario in chemical manufacturing- struggling to coordinate the opinions of sales with manufacturing and supply chain initiatives on what, when, and where products should be produced. The lack of supply chain coordination can lead to frequent changes in production schedules, expedited shipments, excessive stock outs, poor customer service levels, lack of visibility into future demand, inventory in the wrong place and at the wrong time, and erosion of your margins.08/07/2009
In dozens of industries and in millions of applications around the world, dangerous chemicals are transferred from their original shipping containers into smaller jugs or buckets or applied to other end-use processes. Historically, the predominant dispensing method in many of these applications has been through an open system where the liquid is poured out of the container. With a poured system, the container is often flipped on its side and the liquid is poured into a secondary container. The user then just carries the bucket to wherever it needs to go. A mental image of this technique quickly reveals its potential dangers and inefficiencies.02/13/2009
Liquid entrainment in a gas stream can be a disturbance in many industrial processes.
