An industrial process for obtaining sodium carbonate from limestone, ammonia, and brine.
- ‘In the Solvay process, carbon dioxide and ammonia are passed into a concentrated solution of sodium chloride.’
- ‘In the Solvay process, ammonia and carbon dioxide are used to produce sodium carbonate from salt and limestone.’
- ‘Another object of the invention is to modify the Solvay process to eliminate the production of calcium chloride.’
- ‘The Solvay process is exothermic, so waste water must be cooled before it is returned to rivers or ocean.’
- ‘Were it not for the recycling of ammonia, the Solvay process would be economically impractical.’
Late 19th century: named after Ernest Solvay (1838–1922), Belgian chemist.
