Abstract
При охлаждении кислоты, которую извлекают из абсорбционного аппарата установки по получению серной кислоты, кислоту закачивают из резервуара насоса для перекачивания кислоты в теплообменник и затем снова подают в абсорбционный аппарат, в котором воду в качестве теплоносителя нагревают в теплообменнике теплом кислоты и, по меньшей мере, частично превращают в пар, и воду отделяют от пара. Предусмотрено, что кислоту подают в межтрубное пространство теплообменника, а воду подают в элементы теплообменника, расположенные в межтрубном пространстве, и, по меньшей мере, частично превращают в пар, при этом образованный в теплообменнике пар отделяют от воды в паросборнике и полученную таким образом воду направляют рециклом в теплообменник с помощью насоса.
