In terms of the tower design, what needs to be done regarding equipment and processes? Put it in simple terms, please. Thank you

Design aspects related to the process: material balance, vapor and liquid load on the tray sheets, physical property parameters, and design of tower structure parameters, including tower diameter, tower height, opening ratio, tray spacing, etc. Equipment design: Draw equipment diagrams based on the requirements of the process, and carry out relevant verification calculations.

In terms of process design: Create a diagram showing the conditions of the tower body, determine the diameter of the tower. Based on the schematic diagram of the internal components, design the total height of the tower, the location of manholes, the connections on the tower, as well as the location and size of the inlet and outlet ports. For packed towers, determine the type of packing used, the number of sections, and the height of the packing in each section. For tray towers, determine the number of trays, the spacing between trays, the number of flow paths per tray, the type of trays, the opening ratio, the area of the downcomers, the height of the weirs, and the bottom gap, among other dimensions. In terms of equipment design: Prepare a schematic diagram of the internal components. Conduct calculations regarding the strength of the tower body, create drawings for the manufacture of the tower body, carry out design calculations for the internal components, perform strength calculations, distribution calculations, and calculations related to material collection and extraction. There are also drawings for the manufacture of the internal components, and there’s much more content involved.

The calculations for process determination, material balance, heat balance, and towers are generally covered in standard textbooks

Process commissioning: material balance, heat balance, design data (natural conditions, design conditions, geological conditions, medium conditions, materials), tray data, packing data, tower structural dimensions, number and size of openings, height. Installation: orientation of openings. Equipment: strength calculations, equipment ordering drawings, construction drawings

Simply put, aside from the strength calculations for various components of the equipment and the preparation of construction drawings, all other design tasks are carried out by the process engineering team.

You see how difficult the manufacturing process is, right? It’s tough, and basically all the responsibility lies with the manufacturing process itself

In terms of process: energy calculation is done on a per-unit-of-material basis. Regarding equipment: calculate the theoretical number of theoretical plates and the actual number of plates. Feed plate position, process property data, tower load, process dimensions of the distillation and stripping sections, load-performance diagrams, tower height and diameter, calculations for the condensers and reboilers at the top and bottom of the tower, etc

The equipment is only responsible for generating diagrams based on the process conditions; it should not be responsible for calculating the number of theoretical plates, the feed position, the tower load, the load performance diagram, or the diameter and height of the tower. The latter items should all be handled as part of the manufacturing process.

Process is the soul, equipment is the body.

In terms of process design: Create diagrams showing the conditions of the tower, determine the diameter of the tower, as well as the location of each pipe outlet; decide on the number and purpose of these outlets. Determine the location and number of manholes, as well as the number of layers and height of the packing. Choose the appropriate type and material for the packing, determine the height of the support structure, and decide on the type of internal components used in the tower, as well as the type of liquid distributor and the size of its holes. Also determine the height of the tower, as well as the type, height, and material of the wire mesh defoamer. For plate towers, it is also necessary to determine the number of plates, their type, and their specific dimensions.

In terms of equipment design: Calculate the strength of the tower, determine the thickness of the tower body and the support structure, as well as the diameter of the center circle around the anchor bolts and the size of those bolts. Additionally, determine the weight of the tower to facilitate design work by the civil engineering team. The details of the internal components are determined based on specific circumstances. There are still many detailed issues.
