Built for vapor streams conventional VRUs were not designed to handle.

VaporCommander™ is engineered for wet, unstable, and liquid-influenced vapor streams where conventional gas-only VRUs struggle with reliability, maintenance, and uptime.

Wet vapor service Built for liquids and unstable vapor flow.
Reduced venting Capture tank vapors and reduce emissions.
Cold-weather fit Reduce separator and scrubber freeze risks.
Low-touch operation Designed for reliability and reduced intervention.
Why multiphase compression matters

Vapor recovery is not a gas-only problem.

In many field applications, vapor recovery streams contain more than gas. Entrained liquids, intermittent slugs, sand, and variable gas quality can force conventional gas-only VRUs into unstable operation, higher maintenance, or narrower operating windows. A vapor recovery solution designed around multiphase reality gives operators a more practical path to gas recovery, emissions reduction, and broader deployment.

01

Conventional VRUs prefer clean gas

Performance and reliability often deteriorate when liquids enter the system or when flow becomes unstable.

02

Support equipment adds burden

Separators, scrubbers, knockout drums, heaters, and related hardware can raise total cost, footprint, and maintenance exposure.

03

Difficult sites get left behind

Applications with liquids, slugs, or upset conditions often become harder to justify economically or operationally with gas-only architecture.

Why VaporCommander™ changes the equation

Built to outperform gas-only vapor recovery approaches.

VaporCommander™ is a multiphase vapor recovery platform built to work with actual field conditions, rather than depending on idealized gas-only behavior.

Broader deployment

Creates a stronger fit across difficult field conditions where liquids, unstable flow, and upset behavior limit conventional systems.

Greater liquid tolerance

Built around incompressible liquid handling inside compression rather than treating liquid presence as an off-design event.

Reduced surrounding equipment dependence

Supports simpler vapor recovery strategies with less dependence on added support equipment in suitable applications.

Better operating practicality

Improves the practicality of emissions reduction and gas monetization where conventional VRUs become maintenance-heavy.

Advantages of the Fluidstream vapor recovery package

Built on Fluidstream multiphase technology.

VaporCommander™ combines multiphase handling, hazardous-service sealing, intelligent controls, and package flexibility to create a more resilient vapor recovery platform.

Designed for incompressible liquid handling

Fluidstream’s multiphase platform is built around a patented methodology for safely, efficiently, and reliably handling incompressible liquids within the compression chamber, critical in real vapor recovery streams where liquids are often present.

Sealed gland architecture for hazardous service

A patent-pending gland sealing configuration with electronic wear detection and a fully sealed gland arrangement helps contain toxic or corrosive multiphase fluids, including H₂S-bearing streams.

Autonomous control through upset conditions

Full piston tracking supports optimized control, protects against ice and solids buildup, and helps the system operate safely through slugs and changing process conditions.

Long-life alignment in wear-critical areas

The package is designed to maintain alignment in key stress and wear zones, helping extend component and seal life.

Sand-capable sealing configuration

Multiphase piston sealing and gland sealing are configured to optimize life in applications where sand is present.

Flexible drive options with integrated intelligence

In addition to electric drive, Fluidstream offers gas-drive integration with key operating data fed into autonomous controls to maintain performance when fuel gas quality is compromised.

Conventional VRUs vs. VaporCommander™

Buyers evaluating vapor recovery systems are often comparing gas-only VRUs against packages that offer varying levels of liquid tolerance. VaporCommander™ is differentiated by a multiphase-first design philosophy built around real operating conditions.

  • Handles entrained liquids: core design premise of the package rather than a narrow tolerance claim.
  • Operates through slugs and upset conditions: autonomous logic and piston tracking support upset handling.
  • Sealed hazardous-service gland design: fully sealed gland approach with wear detection.
  • Sand-oriented sealing strategy: sealing configured to optimize life in sandy applications.
  • System simplicity at the site level: supports a simpler, broader deployment strategy.
  • Range of viable vapor recovery applications: stronger fit for difficult real-world streams.
VRU Differentiation

Built for the conditions that make conventional VRUs unstable.

VaporCommander™ is designed for vapor recovery applications where gas flow can change rapidly with tank conditions, production cycles, liquid carryover, cold-weather operation, and process upsets. Autonomous control helps maintain stable operation when conventional separator-dependent VRUs become unreliable or maintenance intensive.

Liquid-capable operation

Handles wet gas and liquid-influenced compression conditions without relying on perfect upstream separation.

Reduced freeze exposure

Less dependence on scrubbers and upstream separation equipment helps reduce common winter reliability problems.

Autonomous flow response

Automatically responds to variable vapor flow so the system can remain stable through changing tank pressure and upset conditions.

Engineering notes
  1. Flow conditions calculated at 15℃ [59℉] inlet pressure and with various components operating at 100% efficiency. Flow rates may vary based on inlet pressures, gas content, and other factors. Max gas rates will be reduced by amount of liquids in total fluid. Contact Fluidstream for gas capacity review based on specific liquid rates and operating conditions.
  2. Max gas rates and max pressure differentials can be increased by configuring additional unit(s) in parallel or in series.
  3. Higher horsepower units will yield much higher fluid flow rates at various pressure differentials. Please request pump curves to see flow rates at various pressure differentials.
