Describe what feedstock means in refining.

Feedstock in refining refers to the raw materials that are processed to create finished products, such as fuels, lubricants, and other chemicals. This term encompasses a variety of materials, including crude oil and natural gas, which undergo various processes in a refinery to transform them into usable forms. Understanding feedstock is essential because it highlights the starting point of the refining process and its significance in determining the efficiency and output quality of the refinery operations.

The focus on raw materials is crucial because they are the foundational inputs that define the entire refining sequence, impacting both the type and quantity of products generated. Without feedstock, the refining process cannot initiate, making it a vital concept in the field of refinery operations. This concept is distinct from finished products, waste materials, or temporary storage solutions, which serve different roles in the broader context of the refining process.
