What are the factors that the catalytic unit affects on the pressure drop from the top of the distillation tower to the compressor inlet?

Will increasing the top cooling reflux and steam in the distillation tower affect the pressure drop from the top of the distillation tower to the compressor inlet? Are there any available data or calculation methods for this pressure drop?
The factors affecting the pressure drop from the top of the distillation tower to the compressor inlet in a catalytic unit include: 1. Operating conditions of the distillation tower (such as temperature and pressure). 2. Feed composition and its physical properties. 3. Characteristics of the filler or discs in the tower (such as surface area, porosity). 4. Flow conditions in the liquid and gas phases (such as flow velocity, relative velocity). 5. Changes in steam load and cold reflux ratio. The cold reflux and steam at the top of the distillation column affect the pressure drop, which usually increases due to changes in the flow properties of the liquid and gas. The calculation of the specific pressure drop involves principles of fluid mechanics, and it can be estimated using methods such as the Hagen-Poiseuille equation and Darcy’s law; however, detailed data on the specific device along with its operating conditions are required for accurate calculations and experimental verification. Relevant information can generally be found in chemical engineering design manuals or fluid mechanics textbooks. .
