All-in-one

PurePac Mini is designed to fit in one single sustainable housing, with the compressor, pre-treatment and membrane separation skids inside of one 40 ft. container.

Perfect for biomethane production on a small scale (30 – 65 Nm3/hr biogas flow) with the purpose of gas grid injection.

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 Mini 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
