Min Ho Maeng

Title: Min Ho Maeng: Inventor in Biogas Processing

Introduction

Min Ho Maeng is an inventor based in Newark, Delaware. His patent work focuses on integrating membrane-based gas separation with anaerobic digestion to support methane production and biogas upgrading. He holds 2 patents.

Latest Patents

Maeng’s listed patents describe systems that separate biogas into methane-rich and carbon-dioxide-rich streams, then recycle the carbon-dioxide-rich permeate to an anaerobic digester.

“Membrane Permeate Recycle with Pressurized Anaerobic Digesters” describes a system in which a pressurized anaerobic digester generates biogas for processing through two membrane stages. The membranes separate the gas into a methane-enriched residue stream and a carbon-dioxide-enriched permeate stream. A compressor raises the permeate pressure slightly above the digester’s operating pressure, allowing it to be recycled to the digester’s bottom volume.

“Integrated System and Method for Methane Production Using Off Gas Recycling to Anaerobic Digester from a Gas Separation Membrane Unit” describes feeding raw biogas from an anaerobic digester into a membrane separation unit. The unit produces methane-rich biomethane and a carbon-dioxide-rich permeate, which is returned to the digester and mixed with the digestate.
