“I’m saving energy; where are you? “Petrochemical 303: Shutdown of the liquefied gas desulfurization feed pump”
Thread Content
Disabling the feed pump for liquefied gas desulfurization helps save electricity. In the original design, the stabilized liquefied gas was pumped into the feed buffer tank of the liquefied gas desulfurization extraction tower, and then pumped out again before being sent to the tower. After making changes to the process, the stabilized liquefied gas goes directly into the liquefied gas desulfurization extraction tower, which allows the feed pump for the refined liquefied gas desulfurization extraction tower to be disabled, thereby saving electricity. For example: 45 Kw * 8000 hours = 360,000 Kw; 360,000 Kw * 0.8 yuan/Kw = 288,000 yuan. This savings is quite significant. There are many similar examples; by altering the process and disabling certain pumps, energy can be saved
We stopped using one transfer pump after conducting calculations, which also achieved energy-saving results
