I would like to ask for advice from all of you experts! Issues related to the side-line stripping tower of the vacuum distillation column?

Advantages of a vacuum distillation column with a side-line stripper: Improved product quality: The side-line stripper can effectively remove light components from the products obtained from the side line of the vacuum distillation column, such as certain molecules in the low-boiling fraction, thereby enhancing the purity and stability of the products. Increasing yield: Side-line stripping can boost the yield of CDU (atmospheric and vacuum distillation units), as it effectively separates light components from the main column, thereby stabilizing the residual oil components at the top of the main column. Reduces the burden on the condenser and the bottom of the tower: Since side-line stripping can remove light components, it reduces the cooling load imposed by these components on the condenser and the bottom of the tower, thereby improving the operational efficiency of the equipment. Disadvantages: Equipment complexity and cost: The introduction of a side-stream stripping tower increases the complexity of the entire plant, requiring more equipment and pipelines, which in turn raises the initial investment costs as well as operating and maintenance costs. Increased energy consumption: The side-line stripping tower requires additional energy for heating and cooling, thereby increasing the overall energy consumption of the plant. Operational complexity: The operation of the side-line stripping tower requires more precise control to ensure its efficient operation and to avoid any negative impact on product quality. Advantages of a vacuum distillation column without a side-line stripper: Simpler structure: Without a side-line stripper, the overall structure of the unit is simpler, resulting in fewer pieces of equipment and less piping connection, which lowers the initial investment costs as well as operating and maintenance costs. Lower energy consumption: Since there is no need for additional heating or cooling, the overall energy consumption of the device is relatively low. Easy to operate: Due to the absence of a side-line stripping tower, the operation of the entire facility is relatively simple, which reduces the operational complexity and the need for staff. Disadvantages: Product quality may be limited: Since there is no side-stripping column to remove light components, the content of such light components in the products obtained from the vacuum distillation column may be high, which affects the purity and stability of the products. Production may be limited: The presence of light components may affect the stability of the residual oil components at the top of the main tower, thereby limiting the production capacity of the entire facility.
