Faktori sigurnosti u proračunu debljine zida kolona za rektifikaciju

Abstract

Kolone za rektifikaciju gasa veoma su važan deo svake fabrike. Njihovi iznenadni otkazi svakodnevno uzrokuju ogromne gubitke, dok curenje tečnosti može biti veoma opasno po ljude i životnu sredinu. Iz tog razloga, pravilan dizajn kolone je od velike važnosti, kao i primena ostalih faktora bezbednosti. U ovom radu prikazano je merenje debljine zida sa ciljem da se izračuna stopa korozije i preostali vek trajanja rektifikacionih kolona. Minimalna potrebna debljina zida kolone izračunata je prema najčešće korišćenim međunarodnim standardima i analizirana je dobijena razlika.

Gas rectification columns are a very important part of each onshore plant. Their sudden failures cause huge losses on a daily basis, while fluid leakage can be very dangerous to people and environment. For that reason, the proper design of the column is of huge importance, among the others safety factors as well. In this paper, the wall thickness measure is presented with the aim to calculate corrosion rate and remaining life of rectification columns. The minimum required column wall thickness was calculated according to the most commonly used international standard and the obtained difference was analyzed.
