Custom VOCs Recovery Systems for Oil Depots & Chemical Plants
For vapor emissions from oil depot tank farms and chemical plant process areas, Vohon provides skid-mounted custom systems combining compression, condensation, membrane separation and carbon adsorption as required — capacities from 50 m³/h up to 800 m³/h, recovering solvents while meeting stable emission targets.
- Media: crude oil & product tank breathing vapors
- Typical process: compression + condensation + carbon adsorption
- Capacity: from 50 m³/h, scalable to 400 / 800 m³/h
- Emission: NMHC ≤120 mg/m³; removal efficiency ≥95%
- Interlocked with tank pressure & oxygen level, auto start/stop
- Media: esters, alcohols, ketones, aromatics and other organic vapors
- Typical process: compression + condensation + membrane separation (hybrid)
- Capacity: WHSH-500VOC, 500 m³/h, turndown 30%–110%
- Inlet 8000 mg/m³ → outlet <500 mg/m³
- Recovery rate ≥95%; recovered solvents ready for reuse
- Ketones: acetone, cyclohexanone, MEK, MIBK, etc.
- Esters: ethyl acetate, butyl acetate, propyl acetate, etc.
- Alcohols: methanol, ethanol, isopropanol, tert-butanol, cyclohexanol, etc.
- Halogenated hydrocarbons: dichloromethane, trichloromethane, etc.
- Alkanes: n-pentane, n-hexane, cyclohexane, naphtha, gasoline, diesel, jet fuel, etc.
- Aromatics: benzene, toluene, xylene, etc.
- Ethers: MTBE, dimethyl ether, etc.
- Olefin monomers: ethylene, propylene, butadiene, etc.
Compression
Oil-injected screw compressor, near-isothermal compression, discharge temperature below 50°C; wetted parts in 316L stainless steel with multiple safety interlocks.
Condensation
Condensing temperature above 0°C to avoid ice formation; constant-temperature cold storage for instant start-up, energy efficiency ratio up to 1:3.
Membrane / Carbon
Uncondensed gas is enriched by membrane modules and recycled to the inlet, or polished by carbon adsorption; membrane is physical separation with no hazardous waste, design life 8+ years.
