  • M-5

    A flare gas mitigation system for processing flare gas or associated gas that can enable oil to flow at a well. A simple one skid design that is convenient to ship and redeploy.

    • Area required: 12’ x 40’
    • Fuel production: 5-6.5 bbl/day
  • M-50

    Greyrock’s industry leading movable gas-to-liquids system processes flare gas, stranded gas, disadvantaged gas and NGLs (ethane, propane). Units can be used in parallel to add capacity.

    • Area required: 50’ x 50’
    • Fuel production: 50 – 65 bbl/day
  • P-450

    Modular design for converting gas streams into liquid fuels for low value gas or NGLs and also for large flare gas volumes.

    • Area required: 5-10 acres
    • Fuel production: 450 bbl/day
  • P-2500

    Designed for larger gas volumes in low value natural gas or NGL location.

    • Area required: 10-15 acres
    • Fuel production: ~2600 bbl/day
  • P-5000

    Greyrock’s largest standardized design. Custom and larger designs are available based on customer need.

Watch: How it Works

Movable Systems and Fixed Plants

Greyrock’s Direct Fuel Production™platform enables the conversion of natural gas or waste resources into clean liquid transportation fuels (diesel and gasoline blends). Sizes range from 5 barrels per day to 5000 barrels per day. Our award winning system design is a game changer in how the world produces liquid transportation fuels. M-Class systems are skid mounted, movable systems ideal for a natural gas or flare gas conversion at the well pad, flare gas site or waste gas application. Our fixed plants or P-Class designs come in standardized sizes and custom sizes and designs are available.

  • Use Varied Feedstocks

    Use Varied Feedstocks

    Greyrock systems can accept a variety of input feedstocks. Abundant natural gas and natural gas liquids (ethane, propane, etc.) are ideal in oversupplied markets. In addition, flare gas, waste gases from industrial processes and even waste biomass can be used as feedstocks into Greyrock plants to produce fuels.

  • Produce Premium Fuel Products

    Produce Premium Fuel Products

    Systems produce diesel fuel with premium properties such as no sulfur, high cetane, and good lubricity, and a gasoline blendstock which is a premium blending stock for the highest tiers of gasoline. Other products such as kerosene, hydrogen, and steam can also be produced.
