VOCs處理 - 模組化設備

VOCs Concentrator Rotor

VOCs Concentrator Rotor (HAR)

在處理大風量的低濃度VOCs廢氣時都需要大型設備,大大增加了初始成本和運行成本。
通過使用VOCs Concentrator Rotor,可以將大風量含有低濃度的VOCs廢氣濃縮為高濃度的低風量,高效的處理含有 VOCs 的廢氣。

Choices of Adsorption Media

  • Match the adsorbent media to the emissions in the process
  • Zeolite vrs. Carbon – Complimentary Rather Than Competing Technologies
    • Structural Differences
    • Applications Differ
    • Adsorption Characteristics Differ

Removal Efficiency relates how:

VOC is transferred from large air volumes to adsorbent media prior to exhausting to atmospher

如何涉及去除效率:

VOC 在排放到大氣之前從大風量轉移到吸附介質

Concentration Technology

Concentrators are CAPTURE Devices

  • VOC are removed from process air by adsorption
  • Adsorption media is continuously regenerated
  • VOC destruction after concentrator becomes very economical

濃縮技術

集中器是捕獲設備

  • 通過吸附從製程空氣中去除VOC

  • 吸附介質不斷再生

  • 經由濃縮器後的VOC銷毀變得非常經濟

Suitable Applications for Concentrators

High air volume – low VOC concentration

VOC Concentration <800-900 ppm

  • Process exhaust temperature <120°F
  • No resin, heavy metals, or oils present
  • No halogenated compounds present
  • No sulfur compounds present

CarbonRemoves xylene and most common paint solvents.
Ineffective at removing methanol.
Zeolite with
6Å pores
Removes methylene chloride, methanol and most low-molecular-weight solvents. Somewhat less effective with xylene and solvents larger than 6Å diameter.
Zeolite with
8Å pores
Removes higher-molecular-weight solvents.
Carbon
and zeolite
in a series
weight solvents.
Removes solvent mixtures containing moderate
amounts of methanol (15% to 25%) at low total
VOC loadings (less than 250 ppm). Note that a physical mixture of carbon and zeo-lite on a single substrate is more effective than the two in series at removing high
concentrations of solvents (>300 ppm) with lower
(<20%) alcohol contents.
