by Jim Lane (Hydrogen Digest) From Planet Houston we’ve heard that ENGlobal inked a $20 million to supply process modules that will be used to construct a complete hydrogen production facility. The plant will be a major component of an otherwise unidentified renewable diesel facility with an expected maximum production of 10,000 barrels of renewable diesel per day. ENGlobal — one of the Houston megaplex’s perennial engineering firms in the realm of automation — engineering, detailed design, procurement, module fabrication and automation.
The hydrogen unit design utilizes Haldor Topsoe technology. This highly efficient synthesis gas process consumes approximately 20% less feed and fuel gas than conventional hydrogen plants, and produces no excess steam, leading to substantially lower operating costs and a far smaller carbon footprint. It will mark the first time this innovative technology will be used in the United States, after more than 40 successful implementations worldwide. ENGlobal offers a full range of capabilities to engineer, fabricate and automate these plants, with each application realizing significant cost and schedule benefits through the company’s modular execution strategy.”
Haldor Topsoe’s latest foray into renewable diesel and hydroprocessing
Topsoe already offers the HydroFlex process that is in commercial operation at refineries producing renewable diesel from vegetable oils, animal fats, and tall oil. The result is identical to fossil diesel on the molecular level. This means that the renewable diesel produced from the HydroFlex process can be used as a drop-in diesel without modification of standard car engines.
But last month, Haldor had this to say about their latest and greatest technology:
The Bio-crude Production and Upgrading to Renewable Diesel project will investigate innovative approaches to optimize an integrated, advanced biofuels process in order to produce sustainable renewable diesel at an attractive cost.
The chosen process is catalytic biomass pyrolysis integrated with a hydroprocessing unit. This type of process is generally considered an attractive route towards sustainable renewable fuels. It uses cellulosic feedstocks such as woody biomass, energy crops and agricultural and other wastes, making it a next generation technology.
The focus of the project is to:
- maximize biocrude (also known as pyrolysis oil) yields in catalytic biomass pyrolysis by optimizing the physical and chemical characteristics of cellulosic biomass feedstock, in a commercially viable manner;
- improve efficiency of the upgrading of biocrude to renewable diesel blendstock by splitting the liquid intermediate in fractions that are hydroprocessed individually.
By extraction and distillation, the biocrude is separated into three different streams of similar functionalities; a less polar aromatic fraction (light cycle oil – LCO), a pyrolytic lignin fraction, and a water-soluble fraction. …
Who’s the mystery project developer?
No one can say for sure, but we suspect it might be SkyNRG. READ MORE
