Energy Industry Tower Internal Wire Mesh Demister

1. experience in York 431 demister,

we have more than 12 years experiences in mesh pad demister / mist eliminator, as well as valuable knowledge in related technical calculation, like the operation pressure drop, eliminating efficiency, etc.

In daily work, when we make a price offer for a demister, usually we need to estimate the package info, too, like the weight and package plan. So that either the salesman or the customer can easily inquiry the shipping cost. For a faster response to the customers’ request, I have made this theoretical data sheet as below. Among them, the data for grids and space rods are introduced from “HG/T 21618-1998 Mesh Demister”. And the data of mesh pad is calculated based on York 431 demister’s specifications.

The table is for round shape wire mesh demister only. Generally we think square or rectangular shape mist eliminator’s data are easier to be calculated. While if other complicated demisters’ data are needed. Maybe a CAD software can help us a lot.

3. Where are DEMISTER units used?

Knockout drums and separators – save on capital costs by decreasing vessel size-recover costly fatty acids from stream-reduce compressor maintenance by preventing scale build-up.

Absorbers – reduce overhead losses of glycols in dehydrators to no more than 0.1 gal/MMSCF natural gas-cut losses of absorption oil and amines in CO2 systems.

Scrubbers – reduce chemical discharges from Kraft mill smelt dissolver tank to less than 0.11 kg/dry ton (0.25 lb/dry ton) of pulp-improve scrubber efficiency by removing particulates carried in entrained liquids.

Distillation columns – improve product purities and increase throughput capacities for petrochemicals, organic intermediates, fine chemicals.

Evaporators – prevent carryover loss of valuable products, keep condensate TDS <10 ppm for highest quality boiler feed water-clean up vacuum ejector stream discharge-lower maintenance in vapor re-compression systems.

High pressure steam systems – provide dry steam- cut TDS to <10 ppb in condensate-eliminate build-up on turbine blades.

Refinery towers – increase throughput capacity-take deeper cuts for greater product yields – prolong catalyst life in downstream cracking and reforming units by reducing carbon and metals in side

draws-use lower grade crudes.
