The Coker unit operates under what conditions?

The Coker unit operates under high temperature and low pressure conditions to effectively break down heavy hydrocarbon feedstocks into lighter, more valuable products. The high temperature is necessary to facilitate the thermal cracking process, where larger molecules are broken down into smaller, more useful ones, such as gasoline and diesel. Meanwhile, the lower pressure conditions help maintain the fluidity of the feedstock and prevent excessive carbon formation, which can occur at higher pressures. This combination of conditions is crucial for maximizing the yield and efficiency of the coking process.

The focus on high temperature allows for the necessary thermal energy to promote cracking reactions, while the lower pressure provides an optimal environment for the reaction by minimizing the risk of operational hazards and making the process more manageable.
