The choice of pre-treatment method depends on various factors, including:
Feed Composition The type and concentration of impurities present in the feed will dictate the necessary pre-treatment steps. For instance, a high sulfur content would necessitate efficient desulfurization techniques.
Desired Product Specifications The quality and specifications of the final product also influence the choice of pre-treatment. For example, producing ultra-low sulfur diesel would require stringent hydrotreating processes.
Economic Considerations Cost-effectiveness is a critical factor. The chosen pre-treatment method should balance operational costs with the benefits of enhanced catalyst life and process efficiency.
