hi everyone, does any one have excel calcs on 3 phase or 2 phase seperator, conical bottom tanks and flare stack with gas analysis and depletion that are important for h2s diffusion in air. If you please can you share with community. I m working on conical bottom tank design that I might be able to share once I complete it. Tricky part is the cone which caries the bending moments due to 40 ft high tank above it with sand and water gravity. Thanks
