Controlled Growth of Strontium Sulfate Particles in Aqueous Solution: Inhibition Effects of a Bubble Column Evaporator

In the oil industry, strontium sulfate (SrSO4) scale deposits have long plagued oilfield and gas production operations. This remains an unsolved problem. We here show how bubble column evaporator (BCE) can be used to control aqueous precipitation from salt solutions. Mixtures of nitrate sodium in BCE system were precipitate at different degrees supersaturation. The effectiveness was compared standard mechanical stirring. both processes monitored through turbidimeter, particle counting, Dynamic Light Scattering (DLS) Scanning Electron Microscopy (SEM). results that has a significant inhibition effect so growth rate, even supersaturated remarkable also provides new insights into mechanisms crystallisation, interactions mineral flotation.
