Mobile Waste Gas Recovery Equipment

Mobile Waste Gas Recovery Equipment

Mobile waste gas recovery equipment is an environmental protection system that integrates VOC (Volatile Organic Compound) treatment technology onto a mobile platform, such as a trailer or skid. It is specifically designed to address intermittent, temporary, or emergency waste gas treatment needs, overcoming the limitations of fixed installations that cannot be deployed on demand.

Mobile waste gas recovery equipment is an environmental protection system that integrates VOC (Volatile Organic Compound) treatment technology onto a mobile platform, such as a trailer or skid. It is specifically designed to address intermittent, temporary, or emergency waste gas treatment needs, overcoming the limitations of fixed installations that cannot be deployed on demand.

Its core value lies in its flexibility and rapid deployment capabilities, enabling the treatment of pollutants at the source the moment they are generated.

 

Working Principles and Processes

 

The equipment houses an integrated waste gas treatment unit, typically employing a combination of processes to handle diverse waste gas compositions and ensure high treatment efficiency. Common technology combinations include:

  • Condensation + Adsorption: One of the most common combinations. A condensation system first liquefies and recovers high-concentration vapors, followed by an adsorption system (e.g., activated carbon) to deeply purify the remaining gas.
  • Chemical Absorption Pre-treatment + Condensation + Adsorption: Designed for complex operating environments like refineries, this process adds a chemical absorption pre-treatment step before condensation and adsorption to handle pollutants across varying flow rates and concentrations.
  • Adsorption + Catalytic Oxidation (Integrated Desorption & Purification Unit): Some units focus on adsorbent regeneration, capable of desorbing VOCs from saturated adsorbents and completely decomposing them into harmless CO₂ and H₂O.
  • Pre-cooling + Cryogenic Adsorption + Deodorization: Tailored for scenarios such as tank-top vapor recovery, this process combines pre-cooling, cryogenic treatment, adsorption, and spray deodorization to ensure effective treatment and odor-free emissions.

 

Key Advantages

 

  • High Mobility and Rapid Deployment: Highly integrated onto trailers or skids, allowing for quick relocation between different work sites.
  • Modular Design and Flexible Configuration: Features a skid-mounted modular design, enabling the flexible selection of functional modules based on specific waste gas compositions.
  • Efficient Purification and Reliable Compliance: Combined processes ensure high removal rates; for instance, case studies have demonstrated non-methane total hydrocarbon (NMTHC) removal rates exceeding 99.6%.
  • Broad Applicability and Emergency Response: Suitable for intermittent operations-such as unit startups, shutdowns, and maintenance-as well as for emergency waste gas treatment during unexpected incidents.

 

Typical Application Scenarios

 

  • Petrochemical & Refining Industry: VOCs control during unit startup/shutdown and maintenance/overhaul periods.
  • Oil & Gas Storage and Transportation: Treatment of vapors from tank tops and loading racks at gas stations and oil depots.
  • Industrial Facilities: Waste gas treatment for workshops in sectors such as electronics, chemicals, printing, and coating.
  • Adsorbent Regeneration: Serves as mobile desorption equipment to support multiple stationary adsorption units.
