Analysis of silica fouling on nonwetting surfaces

Abstract

Ground water sources used as coolant fluids in a variety of thermal systems such as heat exchangers and power plant condensers contain silica particles that accrete on heat transfer surfaces...

Investigating the potential of hydroxyethylamino-di(methylene phosphonic acid) in inhibiting gypsum crystallization

“…6,7 Therefore, mineral scale formation reduces the lifetime of industrial facilities and leads to increased maintenance or replacement costs. 8 There are various types of mineral scales but the common ones are calcite, 9 barite, 10,11 struvite, 12 silica, 13 and gypsum. 14 Gypsum or calcium sulfate dihydrate (CaSO 4 •2H 2 O) is a crystalline phase in the CaSO 4 -H 2 O system and its formation is important from the natural geochemical and industrial points of view.…”
