Solvent regeneration tower with bottom liquid collection tanks https://bbs.hcbbs.com/thread-2178408-1-1.html (Source: Haichuan Chemical Industry Forum) Original post: Dear experts, our ethanolamine solvent regeneration tower uses a dual-overflow design; there are two liquid collection tanks at the bottom of the tower, and each of these tanks has its own reboiler. The liquid is drawn from these collection tanks and sent back to the bottom of the tower. 1. I’ve never really understood the structure of the bottom liquid collection tank and the bottom section of the tower; could any teacher share some pictures or provide a description? 2. What is the relationship between the liquid level in the collection tank and the liquid level at the bottom of the tower? 3. What is the principle behind drawing liquid from the collection tank and returning it to the bottom of the tower via a reboiler?
