Heating and Thermal Insulation for a NaSH Storage Tank

[EloyRD]

Good afternoon Comunity,

I'm designing a storage tank for Sodium Hydrosulfide (NaHS) 45% solution for a Mine in Peru. Due to the required storage temperature (as pointed in

http://www.genesisenergy.com/assets...hnical_Guide/Technical_Guide_10_31_11zip.pdf)

and the site conditions (Minimum registered temperature: -15 °C; Minimum average temperature: -5°C) we require to provide heating to the storage tanks.

I've been looking in the web and handbooks for some of the properties that are inputs in the determination of the convective heat transfer coefficient for the stored liquid. The properties that I haven't found are:
- Specific Heat
- Thermal Conductivity
- Coefficient of Volumetric Expansion
- Molecular Mass of Liquid
- Boiling Point

I'd appreciate an opinion for a way to estimate the heat loss without the properties or a link to a place with the prperties.

Thanks for any commentary.

Kind regards.

The boiling point is on this site. Have you called the manufacturers? The lab techs should have the properties.

Thank you for the link, I surfed the page for Solvay Chemicals and got also the Molecular Mass.

I contacted the manufacturers and I am still waiting for their information.
