high-pressure process [′hī ¦presh·ər ′prä·səs]

(chemical engineering)

A chemical process operating at elevated pressure; for example, phenol manufacture at 330 atmospheres (1 atmosphere = 101,325 pascals), ethylene polymerization at 2000 atm, ammonia synthesis at 100-1000 atm, and synthetic-diamond manufacture up to 100,000 atm.
