My Own Designed Carbon Dioxide Scrubber Part 2: The Hot Column

Last time, we discussed about the cool column of the Amine Carbon Dioxide Scrubber, which I have just given the name: SCRUBBAMINE. FOR THOSE WHO HAVEN'T READ THE PREQUEL, VISIT THIS LINK: http://thepenbreakers.blogspot.com/2014/04/my-own-designed-amine-carbon-dioxide.html

Now we shall continue with the Hot column.

After the carbon dioxide bonded monoethanolamine passes into the hot column. The hot column has a temperature range between 78°C to 80 °C.

The carbon dioxide monoethanolamine gets slightly heated, and the process is reversed: the monoethanolamine lets go of the carbon dioxide gas and carbon dioxide is then passed into a dehydrator in order to dry it.

When temperatures get high, the carbon dioxide cannot form bonds with monoethanolamine anymore, thus slowly escapes out of the hot column. Mean while, the monoethanolamine evaporates and then again condenses (see diagram above) back into the hot column (without forming any bonds with carbon dioxide). In this way, carbon dioxide is separated from steam.

Well, that’s all for today… Don’t miss next Thursday because we are going to discuss about the whole structure and its importance to the environment.
