Lesson 1: About the system- system and system streams Flashcards
What is the 634 system designed to do?
To reduce the amount of Sulfur, Nitrogen, and Heavy Metals in the 533 Crude (Resid), 536/37 Crude LVGO, 536/37 HVGO, 537 MVGO and Cold feed from the Tank Farm.
Why is it important to remove the sulfur?
Sulfur can impact the environment and lower the quality of the finished product.
