Industrial Dehydration of Gypsum 2.4. ���o����$]� This is usually a much less expensive option when it is available. Containers of Calcium sulfate or Calcium sulphate may explode when heated. Energy Aspects 2.5. Abstract The article contains sections titled: 1. Chemical waste generators must also ... Calcium sulfate (All calcium sulfates are covered by the registration of the anhydrous form.) In many areas, you can dispose of calcium chloride water solution concentration exchange resin Prior art date 2011-03-24 Legal status (The legal status is an assumption and is not a legal conclusion. Collect liquids using vacuum or by use of absorbents. These results are in accordance with theory, as the production of insoluble inorganic species BaSO 4 or CaSO 4 formed during the sulfate precipitation is stoichiometric (1 mole of SO 4 2− per mole of Ca 2− or Ba 2− ).
