Deep cold VOCs recovery equipment

VOCs gas condensation recovery device
1、 Suitable for VOCs gas single material or multi material condensation liquefaction recovery.
1. Hydrocarbons: such as gasoline, crude oil, fuel oil, kerosene, diesel, heavy oil, mixed hydrocarbons, etc;
2. Aromatics: benzene, toluene, toluene, naphtha, etc;
3. Alcohols, ethers, ketones, esters, etc.
Applicable areas for VOCs gas condensation and recovery device:
1. Storage tank area: respiratory volatilization loss of emptying valve ⻔;
2. Loading and unloading transfer area: tank emptying, breathing, volatilization loss;
3. Production and release area: Loss of solvent evaporation in the drum and stirring reaction kettle;
4. The recovery of various volatile volatile organic compounds (VOCs) gases generated in the packaging, storage, and transportation of volatile chemicals, as well as in the chemical and pharmaceutical industries.
Working principle of VOCs gas condensation recovery device:
The volatile VOCs gas can be introduced or other electronic gases can be introduced into the equipment cold box through an introduction machine (with a condensation temperature set at 3 ℃ -40 ℃ -75 ℃ -115 ℃). Other temperature zones can be customized, and the condensation, liquefaction, capture, and separation can be carried out step by step according to the needs and collected in a collection tank. Part of the continuous production processes perform a dual path switching process in the low-temperature section (after one side is blocked by ice, it is directly switched to the other heat exchange cold box for condensation, while the ice blocking side undergoes defrosting treatment). Emissions of other gases are used to achieve condensation, capture, and recovery of gases.
1. Gas processing capacity: 100m ³/h to 2500m ³/h, commonly used specifications are as follows:
5m³/h 、30m³/h、100m³/h 、300m³/h 、400m³/h 、600m³/h 、800m³/h 、1000m³/h 、1500m³/h 、2000m³/h
2. Operating power: 3kW~300kW
3. System pressure difference: 250pa~450pa
4. Minimum temperature: 3 ℃ -40 ℃ -75 ℃ -115 ℃ -198 ℃
5. Explosion proof type: Positive pressure type EXpxdmbII BT4 Explosion proof type EXdII BT4
6. Unit energy consumption: 3 ℃ -40 ℃ -75 ℃, three-stage temperature, condensation and recovery greater than 100m ³/m3
The power consumption of the three-stage condensation recovery device is less than 0.2 kW/m ³ (this indicator may vary slightly depending on the ambient temperature, humidity, site conditions, and solvent gas concentration)
7. Tail gas emissions: For the recovery and treatment of solvent gases, the tail gas environmental emission standard of 20mg/m3 can be met according to demand; If there is low boiling point gas in the gas (which cannot be condensed and liquefied), it can be separated, treated and recovered again through processes such as activated carbon adsorption and membrane treatment to meet environmental protection requirements for the emitted gas.
