Dynamic Modeling and Control of the PRICO© LNG process
نویسندگان
چکیده
For transportation of natural gas (NG), pipeline transportation is often used. However, when gas volumes are moderate, and/or transportation distances are large, the capital and operating costs for pipeline transport become prohibitive. In such cases, transport of Liquefied Natural Gas (LNG) in tankers is often the preferred choice for bringing the gas to the market. In the liquefaction process the natural gas is cooled to around -160°C, and this requires significant amounts of energy. It is therefore important that the process can be operated safely, reliably and efficiently. To achieve this, good control is required.

Single-cycle mixed-fluid LNG process Part I: Optimal design
In this paper, we discuss the design optimization of a relatively simple LNG process; the PRICO process. A simple economic objective function is stated and used on eight different cases with varying constraints. Important constraints are discussed and the results are compared with the commercial PRICO process and with other publications.
متن کاملModel Requirement for Control Design of an LNG Process
Systematic control structure design requires the use of a model of the plant. Developing rigorous plant models based on physical and chemical principles is often a laborious and time consuming task. This paper studies the effect of simplifications of the heat exchanger model on the resulting control structure design for the PRICO LNG process. It is found that significant model simplifications m...
متن کاملOptimal Operation of a Simple Lng Process
Considering the large amount of work that goes into the design of LNG processes there is surprisingly little attention to the subsequent operation. This probably comes from the misconception that optimal design and optimal operation is the same, but this is usually not true. In this paper we are studying optimal operation of a relatively simple LNG process, namely the PRICO process.

متن کاملThree-Phase Modeling of Dynamic Kill in Gas-Condensate Well Using Advection Upstream Splitting Method Hybrid Scheme
Understanding and modeling of three-phase transient flow in gas-condensate wells play a vital role in designing and optimizing dynamic kill procedure of each well that needs to capture the discontinuities in density, geometry, and velocity of phases but also the effect of temperature on such parameters. In this study, two-phase Advection-Upstream-Splitting-Method (AUSMV) hybrid scheme is extend...
