Solvay process: Ernest Solvay (1838-1922) built the first plant for the production of sodium carbonate by the wet method in 1865. The process proved to be more economical than the Leblanc Process, and by the end of the century it had displaced it completely.

Solvay System Migration Doesn't Miss a Beat | Yokogawa Schweiz

Solvay used to simply burn off this gas, but it recently implemented a capture system that gathers the natural gas from its long-wall operation and uses it to help run its refinery. "We were the first in the U.S. to use our waste natural gas as fuel, and we've been doing it for a couple of years," said Kelley. "We compress the 96% to 98% pure natural gas to about 70 psi, and send it to our ...
