The optimal design of single mixed refrigerant (SMR) natural gas liquefaction process is decisive for upgrading the liquefied (LNG) value chain and can be achieved using simulators derivative-free optimization techniques in simulation–optimization frameworks. work consumption reduced by modifying flowsheet manipulating refrigeration cycle thermodynamic conditions composition. goal this paper en...

Gas and oil separation plants are the first main step in production of hydrocarbon products. Depending on properties recovered components from well heads, physical underground rock reservoir, plant design can vary different ways. In mature gas fields, secondary recovery methods often used, which include injection large amounts water into to induce flow wells. The handling this is significant in...

Software engineering is a mature industry of human activity focused on the creation, deployment, marketing and maintenance software. The fundamental concepts are life cycle model; three main components phases - products, processes resources; methodologies for creating, deployment maintaining foun- dation technological advances that lead to new high performance products. As functionality product...

As major experimental modeling methods, static soft-sensing methods have been widely used in modern chemical production process now. In fact, for the sampling frequency to output variable by laboratory analyzer off-line is rather low and uniform, the computed results, which gained from those methods or the existed major dynamic methods such as neural networks, are difficult to satisfy the requi...

Process simulation models can offer significant capabilities for operating personnel to analyze and troubleshoot current performance and to develop optimum responses in a proactive manner. This can increase agility in decision making, improve reliability and lower operating cost. Historically, only engineers have had the knowledge of how to utilize these process models. Limited engineering reso...

This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the co...
