Answer to question: How lignin can be separated from black liquor
Bountiful Applied Research has a proprietary process for this application. For explanation of process, see BARC-USA web page: http:/www.barc-usa.com.
The separation process is patented, and a follow-on process improvement is in process of being patented (patent applied).
The simple process is addition of a polymer to the alkali black liquor, which carries lignin in colloidal dispersion. After treatment with polymer, the black liquor is brought to low pH (approximately 2.5) where lignin separates with clear supernatant liquor remaining.
With use of phosphoric acid to acidify (noting the dilute phosphoric acid is regenerated), alkali chemicals can be recycled with causticizing, same as process used with conventional recovery process in the paper industry. More detailed information (power-point slide presentation and other) can be provided by contacting hcooper@barc-usa.com.

Black currant liquor is often called cassis or creme de cassis. You can usually find that in any liquor store.

No, Black Velvet has no caffeine.
There is liquor because it makes people a lot of money. This country tried to ban liquor before and it did not work. Banning liquor just created a black market and more crime.
One of the things that phyloroglucin contains is lignin.
The source of lignin in the soil is dead plants.

Lignin is a biopolymer that gives support to vascular plants, and is thought to have evolved after aquatic plants took on land. many aquatic plants produce lignin or lignin-like polyphenols however. There is still debate on distinguishing terrestrial from aquatic plant lignin.

Lignin would fall into the functional group OH.
lignin hardened vascular tissues to transport water and nutrients
