Abstract

Ovde je obezbedjen postupak kontrole procesa dobijanja sirćetne kiseline katalizovanom karbonilacijom metanola i postupak proizvodnje sirćetne kiseline korišćenjem postupka kontrole procesa. Postupak kontrole procesa čini merenje koncentracija različitih reaktorskih komponenti, naročito aktivnih katalitičkih oblika, metil jodida, vode i metil acetata pomoću infracrvenog analizatora i podešavanjem, kao odgovora koncentracija bar katalitičkih oblika, metil jodida i vode da bi se optimizirala reakcija sirćetne kiseline.[There is provided a process control method for the production of acetic acid by the catalysed carbonylation of methanol and a process for the manufacture of acetic acid using the process control method. The process control method comprises measuring various reactor component concentrations, specifically the active catalyst species, methyl iodide, water and methyl acetate by means of an infrared analyzer, and adjusting in response thereto the concentrations of at least the catalyst species, methyl iodide and water to optimize the acetic acid reaction.
