Exhaust gas purification system and method and data processing system for monitoring at least one exhaust gas purification system

A system for monitoring the state of an exhaust gas purification system for purifying an exhaust gas stream to be purified of an industrial system or an industrial process, wherein the exhaust gas stream to be purified is circulation air laden with at least one condensable fluid, the system comprising:

• a data processing system comprising at least one processor, which is configured to:
• retrieve system data of the exhaust gas purification system from a data cloud, wherein the system data stored in the data cloud were at least partially received beforehand by the data cloud from the exhaust gas purification system, and
• wherein the system data relate to at least measurement data of at least one sensor of the exhaust gas purification system and/or data about at least one adjustable parameter of the exhaust gas purification system;
• and
• determine a quantity characterizing the exhaust gas purification system based on the retrieved system data, and
• an exhaust gas purification system comprising:
• a communication interface which is configured to send the system data generated in the exhaust gas purification system to the data cloud, and
• at least one main-condenser having a feed port and an exhaust port and at least one main condensation stage, the at least one main condensation stage comprising:
• a condensation chamber being accessible by or permeable for the circulation air;
• and
• a cooling coil at least partially arranged inside said condensation chamber and permeated by a cooling medium;
• and
• a circulation air feed line being connected to said feed port of the at least one main-condenser and being connectable to a source of circulation air laden with the at least one condensable fluid,
• wherein a circulation air exhaust line is connected to said exhaust port of the at least one main-condenser,
• wherein a side-stream off-gas extraction line is fluidly connected to at least said condensation chamber of the at least one main-condenser,
• wherein a volume flow of the circulation air streaming in said condensation chamber is split into a high volume re-circulation stream leaving the at least one main-condenser through the circulation air exhaust line and a low volume off-gas side stream, and
• wherein the high volume re-circulation stream is a purified exhaust gas stream.
