Title: Способ опреснения морской воды
Inventor: RONGVED POL
IPC: C02F103/08
Filed: 2000-09-27
Granted: 2004-11-10
Abstract: Изобретение относится к опреснению морской воды и солоноватой воды и к удалению вредного газа СО 2 , содержащегося в выбросах из установок для сжигания. Для осуществления способа отходящий газ, богатый диоксидом углерода (СО 2 ), отводят в технологическую камеру, при этом морскую воду после перемешивания с аммиаком, предназначенным для ослабления связи в молекулах соли NaCl, закачивают в камеру и рассеивают во многих точках возле верхней ее части в виде мелких брызг, подвергая там воздействию отработанного газа, содержащего СО 2 . Внутренние связи молекул соли NaCl ослабевают благодаря присутствию в воде аммиака, присоединяющего и оттягивающего атом Cl. В камере СО 2  присоединяется и оттягивает атом Na от молекул соли и дополнительно ослабляет связи, разрывая их. Образовавшиеся два тяжелых твердых вещества Na 2 CO 3  и NH 4 Cl удаляют в отстойнике, расположенном ниже. Опресненная морская вода перетекает из отстойника для ее последующего использования в коммунальном и сельском хозяйствах. При этом также обеспечивается утилизация отходящего газа и удаление вредного СО 2  из отходящих газов перед их сбросом из технологической камеры в окружающую среду. Твердое вещество - соль NH 4 Cl можно повторно перерабатывать для получения аммиака, а второе твердое вещество - соль NH 2 CO 3  является товарным продуктом, который может окупить стоимость процесса. Способ предназначается в основном для опреснения воды с максимальной концентрацией соли 22%. 3 з.п. ф-лы.
