This effort focuses on morphology of cyclopentane hydrates formed from pure and saline water. Different brine solutions of Na₂SO₄, NaCl, NaCl-MgCl₂, or NaCl-KCl-MgCl₂ are considered at different concentrations and subcoolings. Especially, a small close reactor cell was used under a microscope with neither agitation nor seeds. Results show that the CPH crystals morphology is approximately comparable at the same subcooling, while the size of the individual crystals drops significantly with increasing of subcooling, regardless the type of salts and their concentrations.
