Desulfurization tower calculation
Thread Content
1) Processing capacity: 40,000 standard cubic meters per day； 2) Pressure loss: less than 5 KPa ； 3) Design pressure: 0.7 MPa; 4) A safety valve is installed, and a ball valve is attached to this safety valve ； The setting pressure of the safety valve is 0.5 MPa; the safety valve is installed at the top of the equipment ； 5) Diameter of inlet and outlet pipes: DN150; pressure gauges are installed on the inlet and outlet pipes ； 6) H2S content at the desulfurization inlet: 500 PPM/m3 ； 7) Vertical installation, with gas flowing downward and exiting upward; the tower is supported by ceramic balls, and an operation platform, ladder, and hook are installed at the upper part of the tower to facilitate the replacement of the desulfurization agent ； Since the mountain roads leading to the site are not suitable for transporting large-scale equipment, it is necessary to minimize the volume of the desulfurization tower; the specifications shall be determined based on an on-site inspection. 8) The equipment must be equipped with a waste discharge pipe. 9) Working fluid temperature: 10~30℃ ； 10) The type of desulfurization agent used is an iron oxide solid desulfurization agent at room temperature; this is determined based on the inlet pressure and flow rate, with a replacement cycle of 60 days. 11) Desulfurization effect: below 20PPM/m3, with a desulfurization efficiency of 97.5% ； The sulfur removal capacity of ordinary desulfurizers is 15%, which means that one ton of such desulfurizer can remove 150 kilograms of sulfur. 12) The ambient temperature of the desulfurization tower ranges from -25°C in winter to 45°C in summer; insulation is required (to be provided by Party A, while Party B, when manufacturing the tank, should take into account the convenience of installing such insulation). How to perform size calculations? Thank you.

It shall be designed, manufactured, inspected, and accepted in accordance with GB 150-2011 \"Pressure Vessels\" and NB/T 47041-2014 \"Tower Vessels\", and shall also be subject to the supervision stipulated in TSG 21-2016 \"Safety Technical Supervision Regulations for Fixed Pressure Vessels\". (2) The design and manufacturing of this equipment shall be carried out by design and manufacturing units that possess the appropriate qualifications; otherwise, it shall not be put into use.
The calculation of the diameter of a desulfurization tower falls under the category of process calculations; it is necessary to determine the gas velocity at the inlet point using relevant process parameters, and then calculate the gas velocity inside the tower, in order to determine its diameter. It is recommended to find someone who can provide the necessary conditions, or have the owner supply the relevant process parameters, so that one can calculate it oneself.
For a desulfurization tower, process calculations must be carried out first, as well as fluid dynamics calculations for the internal components. The person in charge should consult professionals in chemical engineering to determine the diameter and height of the tower, as well as the location where the materials will enter the tower. Finally, perform the strength design calculations for the tower (as stated on the 2nd floor).
@For the Wiseboy tower, can the engineering calculations be done using the software you are developing?
