Week 2 Update
Posted by Austin Jung on February 7, 2019
Good morning all,
Austin here and yesterday’s meeting with Morgan White and Sarthak Prasad went well. I reviewed articles on how power plants use freshwater and the ways to reduce their consumption. The biggest factor in water use at power plants is their cooling system. The metric for measuring this is gallon per KWh and it’s categorized by their withdrawal, consumption, and discharge. The different types of cooling systems have their own pros and cons. For example wet recirculating cooling is good because it doesn’t withdrawal a lot of water but it consumes more than the other methods. Then an example of an advanced cooling system is a hybrid system that used air and a cooling tower to combine the advantages of a cooling tower and the resourcefulness of using a dry system. The draw backs of using only air is it makes the thermal conversion efficiency go down and increases operational costs. More details can be found in the attached file.
We proceeded to continue research on how our power plant and chiller plants operate by looking at the water and energy consumption of the billing logs. We plan on meeting with Mike next week to gain more insight on the chiller plants and their water consumption. Then we looked at the piping layouts for the Universities potable and cooling water pipelines.
To further our research I will finish reviewing some more articles on cooling tower water consumption. Then find articles with more detail on how cogeneration plants work and what metrics are used to measure their energy and water consumption. There should be more data on this from different European studies because they have similar systems like ours at Abbott. Lastly I will familiarize myself with our systems by researching the chiller plants and Abbott information given on the Facility & Services webpage.
