Expert lecture #4

On 12/14/16, The expert was Ronald’s dad (Junbo). Junbo is a chemical engineer. He does a lot of experiments, and he said only 10% of them succeed. He comes up with solutions how to reduce the waste on Earth. On battleships, they produce a ton of waste each day. But how do you get rid of it if you do not dump it in the ocean?

This comes with super critical fluids. A fluid is super critical when high temperature and pressure go past the critical point, the liquid is super critical. Junbo can be exposed to radiation sometimes. The lab is highly in security for safety reasons. He said some experiments took 24-48 hours. The experiment is to fire a highly voltaged electricity on a seal with water. A laser measures the reaction, and then passes it to a computer. Safety is really important, the computer is activated by the badge the workers wear. Between the computer room and the testing room is 3 thick walls with locked doors on each one.

Junbo is a experimenting chemical engineer that gave us an intro to super critical fluids. This can reduce trash in the ocean and protect our envoironment. We had a good time with Junbo learning about chemicl engineering.
