Energy Philosophy in Prospective Petrochemical Projects
MetadataShow full item record
The process design of large, highly integrated and energy-efficient petrochemical plants will depend significantly on the local energy market. The pricing, availability and possible offtakers for steam, power and fuel consumed and produced by the unit often dictate the process configuration of the plant. Of great influence also are the local ambient conditions that provide the ultimate heat sink, either by cooling water or directly by aircoolers. This paper introduces the complex issues involved with establishing an energy philosophy for major petrochemical projects. This philosophy subsequently directs many aspects of the fundamental process design of these plants. For illustrative example ethylene plants are considered. Ethylene is the major building block for plastics and other petrochemicals. The ethylene plant is a major consumers of hydrocarbons that have potential value as fuel. Economic optimization of ethylene production depends upon efficient use of energy within the plant. We will examine several alternative plant configurations that respond to different local energy market situations.
