How is the amount of catalytically pre-heated dry gas determined? How are flow volume and mass converted?
Thread Content
In normal production of catalytic units, dry gas pre-pressurization is generally used, with steam flow reduced to a minimum. How is this minimum value determined? For example: riser pressure drop, density, etc. What are the appropriate values for these parameters in general? How to convert the volumetric flow rate and mass flow rate of dry gas?
Should it be converted based on equal mass flow rate?
Isometric conversion; for example, 1 ton of dry gas at a pressure of 1. At 0 MPa and room temperature, what is the flow rate in standard cubic feet?
In principle, the amount of dry gas should be sufficient to achieve the effect of steam lifting; the specific amount depends on the actual conditions of each installation. The mass flow rate of dry gas equals the volumetric flow rate of dry gas multiplied by its average density.
What is the average density of dry gas?
