MemPore Receives United States Patent on Oil Recycling Technology

MemPore announces it has been granted U.S. Patent No. 9,993,775 for its “Used Oil Recycling Filtration Assembly”.  This assembly is the key component of MemPore’s technology and systems for recycling used oil into clean base oil using nano-filtration membranes.

Membranes have been used for decades as an economical means for water desalination but have never been successfully applied to used oil.  The MemPore technology, developed initially at the National Research Council of Canada, solves this problem and produces a base oil that meets all API specifications in terms of both chemical composition and physical characteristics.  MemPore’s first commercial scale System was commissioned in June 2017.

The entire MemPore System can be located within a standard height room of less than 700 square feet, is economical and easy to operate, and can be acquired at a fraction of the cost of the standard re-refining technologies (vacuum distillation and hydro-treating) for an equivalent capacity. The MemPore System therefore provides a means for companies which either generate or collect used oil to convert this resource into valuable base oil, rather than merely selling it to others for burning or re-refining.  It provides a 70% yield of base oil, is environmentally friendly, and produces 71% fewer greenhouse gas emissions than other forms of oil recycling.  Alastair Samson, MemPore CEO, notes: “The granting of this patent by the U.S. Patent Office reaffirms the strength of MemPore’s technology and assures our customers and investors of positive news in future months and years.”
