Several aspects of crossflow membrane filtration, including process design, equipment selection and control, are detailed here A membrane, also referred to as a semipermeable membrane, is a thin layer of material that selectively passes one or more components of a…
There are many physical properties that can impact the ultimate performance of adsorbent media in gas-phase filtration applications Gas-phase filtration media specifications may list numerous physical parameters, such as shape, moisture content, bulk density, impregnation level, size and hardness (crush…
Applying mass and energy balance calculations yields critical operating insight Cooling towers are an important unit operation in chemical process industries (CPI) operations. Applying mass and energy balance calculations enables process engineers to evaluate evaporation loss, blowdown and makeup-water requirements,…
The Dry-Pro line of dry vacuum pumps (photo) feature contact-free operation that requires no lubrication in the pumping chamber, minimizing process contamination and pollution caused by the pump operation. The Dry-Pro line offers dry-screw vacuum-pump designs with fixed- or variable-pitch…
With cross-flow microfiltration, suspended particles can be removed from pickling acid effectively. Due to their high resistance against acids, caustics and abrasive metal particles, the T-CUT tubular modules (photo) are particularly suitable for this application. The symmetric tubular membranes are…
As a replacement for conventional submersible pumps, this company supplied two eight-stage, sealless canned-motor pumps of the TCAM 30/4+4 Series to a Swiss fine-chemicals company as an alternative to conventionally sealed pumps. The supplied submersible pumps (photo) are the longest…
This company has updated its LiveLink for SolidWorks products. As an add-on to the company’s Multiphysics software, LiveLink for SolidWorks allows a computer-aided design (CAD) model to be synchronized between the two software packages. The latest version of LiveLink for…
The EBP Series of explosion burst plugs (photo) are used to protect plastic extrusion equipment from overpressurization. The EBP Series’ welded design provides a flush attachment, preventing potential product buildup. Stronger welded joints make EBP devices more resistant to increased…
The BW Clip4 (photo) is a new four-gas, portable monitor that can operate continuously for two years without the need to change sensors or charge batteries. BW Clip4 monitors significantly reduce maintenance costs associated with fleets of portable gas detectors…
This column is based on “Sulfuric Acid Production from Sulfur via Double-Contact Process – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/sulfuric-acid-production-cost. Sulfuric acid (H2SO4) is among the most important industrial chemicals, with large-scale uses…
