A revised model for compressor design and scheduling in gas-lifted oil fields

Optimization of a network of compressors in parallel: Real Time Optimization (RTO) of compressors in chemical plants – An industrial case study

“…Fig. 4 presents the classification of the optimization of compressor stations considering four main categories of applications: (i) natural gas networks [11][12][13][14], (ii) utilities [15][16][17], (iii) gas storage applications [7] and (iv) other applications [18]. Furthermore, the examination of the optimization problem can consider different time horizons, continuous operation or/and discrete events.…”

“…future information) is a scheduled maintenance of a compressor, which might influence the decisions for the current operation. The single-period optimization can be further classified as steady-state pipeline optimization [12,14,19,20], optimal load sharing [10,15,21] and optimal selection of compressors [10,13,16,18,22]. The steady-state pipeline optimization examines the optimal operation of the fuel cost minimization problem [14] considering information of one period [20].…”

“…The optimal load sharing is the focus on this paper and it will be presented in Section 3.2. The third category involves discrete events in the formulation of the optimization problem, for example variables which represent which compressor stations operate (on or off) [13] or binary variables for deciding assignments of gas-lift compressors to end-users (wells) [18].…”
