Correction: Bordvik et al. Experimental Investigation of Deposition of Silica Nanocolloids by Depressurizing Supercritical Water Vapor. Energies 2025, 18, 813

There was an error in the original publication [1]. There was a calculation error in the approximation to the molecular mean free path used in the calculation of estimated deposition velocity, and thereby, the estimated concentration of solids passing through the test sections. This led to an update in the estimated deposition caused by thermophoresis presented in Table 3 and updated estimated deposition in Figures 5 and 13. The corrected

and Figure 5 and Figure 13 appear below.

The sentence “All these tests have negative thermophoresis, meaning that the average measured wall temperature, which is affected by the heated chamber surrounding the test rig, is higher than the steam temperature, causing a temperature gradient in the opposite direction to the particle transportation and thus slowing down deposition.”, in page 11 and 12 is to be removed as this information is now replaced by the updated figure text.

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
