Description

Purpose

Battelle as operator of Pacific Northwest National Laboratory (PNNL) is requesting information from companies with demonstrated engineering, procurement, and fabrication experience of biomass processing and conversion plants (or hydrothermal processing technologies) with specific interest in hydrothermal liquefaction plants.

The information gained from this RFI will identify companies with the interest and experience to successfully design and fabricate a pilot scale hydrothermal liquefaction (HTL) pilot plant capable of processing biomass at a scale of 0.5 dry tons per day (dtpd) based on Battelle-s internal concept. The primary purpose of the HTL pilot plant will be to demonstrate successful, uninterrupted operation for 500 consecutive hours producing approximately 1 barrel per day of biocrude product.

Background

HTL has the potential to be a nexus between diverse organic waste management and biofuels production. HTL is well suited for conversion of high moisture organic materials, such as municipal wastewater sludges, algae, food waste, manures, and other agricultural wastes into biocrude oil. The resulting biocrude is suitable for refining into renewable liquid fuels, including synthetic aviation fuel, marine fuel, and renewable diesel.

The principles of the HTL process were first outlined over a century ago. While conceptually straightforward, the development of HTL technology at pilot and commercial scales has been limited. HTL involves the use of hot, near-critical, compressed water (373.9 °C and 220.6 bar) as both a solvent and reactant to convert biomass into biocrude. During this process, a series of reactions take place, enabling the breakdown of polymeric substances within biomass into a water-insoluble biocrude, alongside water-soluble compounds in an aqueous phase, gases, and solid residues.

Interest in the HTL process surged during the crude oil crises of the 1970s and 1980s, prompting significant resear...
