Chemical & Coking
Coking flue gas treatment, tar capture, VOCs recovery and corrosion-resistant dust collection.
Working condition
Recommended configuration
Each row shows the process stage, the machine we normally select and the point that decides whether it performs on site.
| Process stage | Recommended equipment | Selection point |
|---|---|---|
| Tar and heavy fraction capture | Wet electrostatic precipitatorGP-CDPK / GP-WESP Series | Conductive FRP or 316L construction for acid mist and tar aerosol. |
| Acid and alkali gas washing | PP or FRP spray scrubber towerGP-PP / GP-FRP Series | Material selected per chemical and temperature, pH dosing with conductivity control. |
| Organic exhaust oxidation | RTO or catalytic combustion unitGP-RTO-2 / GP-RTO-3 Chamber | Halogen and sulphur containing gas needs downstream scrubbing after oxidation. |
| Low concentration odour | Activated carbon adsorption unitGP-AC Series | Pre-filter upstream, differential pressure monitoring for replacement timing. |
| Odour polishing | UV photocatalytic odour purifierGP-UV Series | Used downstream of scrubbing or adsorption for residual low concentration odour; pre-filter required where mist is present. |
| Flue gas from process heaters | FGD and SCR systemGP-ULE Series | Compact layout for constrained plots, bypass damper for maintenance. |
Energy
Chemical plant exhaust standards and explosion protection classification are defined by national and site regulation. Equipment selection must follow the hazard area classification of the installation point.
