VAPOR RECOVERY & EMISSIONS REDUCTION SOLUTIONS

   Ejectors   

WHAT IS AN EJECTOR?

Ejector - Diagram.jpg

Ejectors use the energy of a high pressure fluid to entrain and compress a low pressure fluid.

​

Ejectors are also known as ‘Eductors’, ‘Surface Jet Pumps’ or ‘Velocity Spools’.

​

Ejectors Are Compressors!

​

  • No moving parts

  • Zero maintenance

  • Often utilize ‘waste’ energy

  • Fast-track project time

  • Do not trip or fail

  • Light & compact

  • Zero emissions

  • Universal Design

Vapor extraction, the removal of volatile organic compounds (VOCs) from soil using vacuum, has proven to be a highly efficient and cost-effective

method of in-situ soil remediation.

 

  • Vapor Extraction Vacuum Blower & Motor

  • Condensate Filter Separator

  • Vacuum Relief Valve

  • Air Dilution Valve

  • Vacuum Gauge

  • Control Panel

  • Base Skid

BTEX ELIMINATOR SYSTEM SHELL & TUBE

  • A counter flow stainless steel tube and bundle heat exchanger condensing system used to capture and recycle  BTEX and VOC vapors from the dehydrator still column

 

  • Closed loop system is an ideal pollution control system as it eliminates BTEX and VOC vapor emissions

 

  • Pays for itself by generating revenue from burner fuel savings and condensate recovery

 

  • Condensed liquids are collected in the tank and automatically transferred to storage

 

  • Residual VOC vapors are sent to the re-boiler main burner and used for fuel

 

  • Low initial cost

  • Recovers fugitive condensates for resale

  • Uses no electrical power

  • Easy to install
