• PurePac Compact

    Biomethane production for any industry. Our complete biogas upgrading solution for the capacity between 65 – 400 Nm3/hr biogas flow.

    Lets get started!Learn more first ↓

Compact & modular

PurePac Compact is a compact and sustainable biogas upgrading solution, with the compressor and membrane separation skids inside of one 40 ft. container and the pre-treatment situated outside of the housing. Using this compact type as complete indoor unit, as in-building solution, is also possible.

Perfect for the upgrading of 65 – 400 Nm3/hr biogas to biomethane with the purpose of gas grid injection or production of vehicular fuel (bio-CNG). As an option, the system can be extended with a CO2 recovery system for the production of food-grade CO2.

High methane yield

Use of highly efficient membrane technology guarantees a methane yield of ≥99.5%.

Easy to Operate

Fully automatic operation with remote control and monitoring.

Easy installation

Standardized, modular units designed for easy on-site installation and low installation costs.

Low costs

Smart design and high-quality components result in low energy consumption and low maintenance costs.

PROVEN MEMBRANE TECHNOLOGY

PurePac Compact uses a 3-stage membrane arrangement with the highest selectivity for the upgrading of biogas. Its smart and patented design results in the highest efficiency (>99.5%) and almost no methane slip (<0.5%). Depending on the grid or user requirements, the gas can be purified to the preferred methane concentration.

BRIGHT’S PROCESS IN 3 STEPS:

  • PRE-TREATMENT OF BIOGAS
  • COMPRESSION AND HEAT RECOVERY
  • SEPARATION BY 3-STAGE MEMBRANE ARRANGEMENT
