process overview

Vapor Recovery Units (VRUs) capture VOCs and HAPs from storage tanks and loading/unloading operations. Primary drivers: EPA 40 CFR regulations and EU Industrial Emissions Directive (IED) mandating 95%+ recovery and strict emission limits (150 mg/Nm³).

Absorption

Membrane separation

Condensation/ refrigeration
Activated carbon adsorption (Best Available Technology)

Key Performance Metrics

Proven results that drive operational excellence

Emissions (outlet concentration)

Double-stage VRUs achieve 150 mg/Nm³, some as low as 5-20 ppm

energy reduction

VRU retrofit with dry screw pump + VFD = 40% power reduction 

Recovery rate

95% to 99.9%+ (meeting EPA 'Quad O' rule)

payback period

1-11 months for storage tank VRUs; <2 years for retrofits 

products & equipment

Comprehensive solutions for every requirement

SUSTAINABILITY & COST EFFICIENCY

Environmental & Economic Benefits

VRUs are cornerstone of sustainable operations. Environmentally, they prevent VOC/HAP release (smog precursors, health hazards). Economically, they embody circular economy - recovered hydrocarbons/solvents returned for sale or reuse, creating direct revenue and rapid payback.
