Use of renewable energy in olefin synthesis

Abstract

An olefin synthesis plant comprising: a feed pretreatment section configured to pretreat a feed stream; a pyrolysis section comprising one or more pyrolysis reactors configured to crack hydrocarbons in the feed stream in the presence of a diluent to produce a cracked gas stream; a primary fractionation and compression section configured to provide heat recovery from and quenching of the cracked gas stream; remove a component from the cracked gas stream; and compress the cracked gas stream, thus providing a compressed cracked gas stream; and / or a product separation section configured to separate a product olefin stream from the compressed cracked gas stream, wherein the olefin synthesis plant is configured such that, relative to a conventional olefin synthesis plant, more of the energy and / or the net energy required by the olefin synthesis plant and / or one or more sections thereof, is provided by a non-carbon based and / or renewable energy source and / or electricity.

Description

technical field [0001] The present disclosure relates to the use of renewable energy in the synthesis of olefins; more particularly, the present disclosure relates to the electrification of olefin synthesis plants; natural gas / fossil fuels) to reduce environmental emissions such as carbon dioxide. Background technique [0002] Chemical synthesis equipment is used to provide a variety of chemicals. Typically, specialized fuels are burned or "burned" to provide reaction heat for chemical synthesis, energy to heat one or more process streams, energy to vaporize liquids (e.g., using boiling water as a diluent), work (e.g., to drive a compressor or pump) ) or energy for other process operations of the entire chemical synthesis facility. Such flaring or burning of fuels leads to the generation of fumes which may be harmful to the environment, and also leads to a loss of energy efficiency of the process. Likewise, steam has traditionally been utilized as a plant-wide heat and / or...

AI Technical Summary

Problems solved by technology

Steam for heat and / or energy transfer is often generated by the combustion of fuels, resulting in additional smoke generation and further loss of energy efficiency during chemical synthesis

In addition, the use of materials that would otherwise be available as reactants for combustion as fuel also reduces the amount of desired chemical product produced from a given amount of material in a chemical synthesis facility
