6.5

A factory method that makes soda ash from salt using ammonia and carbon dioxide

noun
/ˈsɒlveɪ ˈprɒsɛs/

Specialized

: proceso Solvay

Today, most of the world's sodium carbonate is made using the Solvay process.

Examples

The Solvay process revolutionized the chemical industry by enabling large-scale production of soda ash.
Ammonia is recycled during the Solvay process, making it more economical and environmentally friendly.
The Solvay process is essential for soda ash production.
Many industries rely on the Solvay process for efficiency.
The Solvay process is the primary method used worldwide to produce sodium carbonate from sodium chloride.
Due to its efficiency, the Solvay process has become the standard for soda ash manufacturing in many countries.
In the Solvay process, ammonia combines with carbon dioxide and sodium chloride to create sodium carbonate.

Morphology

Solvay + process

This is an eponymous phrase: 'Solvay' is a proper name and 'process' signals a method, so a learner who knows the constituents would infer it refers to some method associated with Solvay but would not be able to derive the specific meaning (production of sodium carbonate). The specific chemistry and product are arbitrary and tied to the name, giving only partial cueing rather than full compositional predictability.

Etymology

Solvay process is named after the chemist Solvay, who created a method to turn salt into 'sodium carbonate', called 'soda ash', using ammonia and carbon dioxide. So, Solvay process means the industrial method for making 'sodium carbonate'.
