Dewatering, drying and extraction - a new Patent !! 4

Currently, most of the proposed methods in the biofuels-from-algae space require the extraction of immobilized oil from algal biomass.

However, regardless of the oil extraction technique used, and some are more efficient than others, getting to the oil is usually very expensive in terms of capital and energy costs.

In some instances, the amount of energy consumed to extract the oil can actually exceed the energy value of the end product.

Uniteltech's new patented processm as per them involves minimal dewatering, and completely bypasses the energy intensive drying and oil extraction steps.

Can someone give me the url of their patent or more idea of the patent. I am excited.
I couldnt get much from their site.

    A new way to manage dewatering, drying and extraction !
    I am also interested.
    I hope someone in the club is in the know. Or atleast the Oilgae team writes about it.
    It will be great to get to know the latest ideas in algae to oil scenario.

    The operative words are " energy intensive drying "
    Wonder what it can be !!

    The most important thing the article is saying is this
    " In the Unitel process, the feedstock a slurry or soup of water and cultivated algae (1% to 20% by weight) is continuously treated in a special hydrolysis reactor to yield 1) a fatty acid product, 2) a sweet water stream containing glycerol and other solubles, and 3) deoiled algal biomass. A small fraction of the fatty acid product is fed back into the reactor as catalyst. "

    Then they add how the byeproducts are also used as given below, indicating that it is a viable proposition.

    It is this hydrolysis reactor that reduces the cost of a. drying and b. extraction. That is very very interesting.
    The nutrient rich sweet water is recycled into the algae propagation tanks, where the carbon in the glycerol serves to promote the growth of phytoplankton. The deoiled biomass (consisting primarily of proteins and carbohydrates) is dried as a food ingredient for animal consumption."
