Abstract
In order to create an economic two-stage heat exchanger system which is capable of cooling cracked gas from short-term splitting furnaces, which is capable of flexible operation utilizing changeable charging stock, the two stages of the heat exchanger are integrated in one device, in order to avoid the necessity of delivering the cracked gas to a second stage via long, hot pipelines. In addition, the system has the capability of switching the heat exchanger plant over to a single-stage operation.
