A raschig ring is an indispensable component of a mass transfer column, helping promote contact between the liquid and gas phases and minimizing liquid holdup in the column. Furthermore, they’re long lasting and cost effective, making them suitable for use in commercial fractional distillation columns.
PTFE raschig rings are widely known for their resistance to high temperatures and acid solutions, boasting the largest surface area among tower packing options and being capable of withstanding heavy loading, process upsets and temperature shocks. We offer sizes suitable for various industrial applications; depending on the nature of your application we may suggest glass raschig rings as a preventative measure against radioactivity in nuclear processing environments.
A pall ring resembles a Raschig ring in terms of equal height and diameter, yet several portions of its side walls have been cut or bent inward to create windows and tabs to prevent entrainment of liquid, leading to more efficient gas-liquid distribution, lower pressure loss, and decreased HETP levels. It can be particularly helpful in acid scrubbers or vapor strippers with high liquid loads.
Metal raschig rings from us offer higher crushing strength, acid resistance and lower operating costs than their competition, making them suitable for use in refineries, petrochemical industries and combustion plants as catalyst support for catalyst support applications as well as gas processing and heat transfer applications.
