What are the disadvantages of steam cracking?
Steam cracking
However the disadvantage is that it may not produce the product that is needed in high enough yield.
For example, if you want a high yield of ethene it is better to make it from ethane or naphtha.
This disadvantage can be overcome by having more than one plant on the same site.
What are the factors that influence the product distribution of steam cracking process?
The feed composition in the cracking processes is one of the crucial factors affecting product distribution and has been highly investigated by different researchers 54, 55 .
Light olefins are produced mainly from alkanes, the higher amounts of n-alkanes result in a higher ethylene yield.
What is the feedstock of steam cracking?
Various types of feedstock are used for steam cracking, such as ethane, propane, butanes, straight-run refinery fractions (naphtha, kerosene, atmospheric gas oil and vacuum gas oil) and hydrotreated feedstock (HVGO and hydrowax).
Ethylene manufacture via the steam cracking process is in widespread practice throughout the world.
The operating facilities are similar to gas oil cracking units, operating at temperatures of 840 °C (1,550 °F) and at low pressures of 165 kilopascals (24 pounds per square inch).
