Calcium sulfate Formula SoftschoolsFighting Scale—Removal and Prevention

Calcium sulfate has three hydrated form the anhydrous CaSO 4 the dihydrated CaSO 4 and the hemi hydrated form It is formed by the cation calcium Ca 2 and the anion sulfate SO 4 2 which form an orthorhombic or monoclinic structure Its chemical structure can be written as below in the common representations used for organic moleculchemical dissolvers Accumulated solid layers of impermeable scale can line production tubing sometimes completely blocking it and are less easily removed Here mechanical techniques or chemical treatments are traditionally used to cut through the scale blockag Nevertheless com mon hard scales such as barium sulfate BaSO 4

Scale problems in production PetroWikiCalcium sulfate Wikipedia

However calcium sulfate scale solubility unlike that of barite scale actually increases with decreasing temperature until about 40 176 C This can decrease the likelihood of scale after the initial mixing deposition The reversal in solubility falloff below 40 176 C accounts for the gypsum scaling observed in surface equipmentCalcium sulfate or calcium sulphate is the inorganic compound with the formula CaSO 4 and related hydrat In the form of γ anhydrite the anhydrous form it is used as a desiccant One particular hydrate is better known as plaster of Paris and another occurs naturally as the mineral gypsum It has many uses in industry
