Risk-based optimization for representative natural gas liquid (NGL) recovery processes by considering uncertainty from the plant inlet

The need to reduce energy requirement and improve operational flexibility of the NGL recovery process is a challenging problem. Different design options have been developed over the past four decades. This paper presents optimization of six selected process schemes subject to various upstream feed c...
