Abstract

Mahsakazemi

A computer simulator is written to optimize the conditions of oil and gas separators using Hysys and Matlab software. Off gases in some wellhead equipment of south of Iran are burnt in flare. In the present paper, the separators of one of these wellheads are simulated. By changing different variables such as the plus fraction splitting methods and the temperature of separators the condition with the least difference with empirical data of crude oil separator test was selected based on which the optimal pressure of separators which minimize total GOR function was calculated. The results show thatusing oftheCavett-Edmister method leads to the lowest value of error andtemperature changes have little effect of the separators conditions.
