I work at a chemical plant as an Instrument and Electrical Technician, my main responsibility is high voltage systems and rectifiers. The plant has a 450 Mega Watt (MW) Cogeneration plant, the chemical plant uses about 250 MW and the rest goes to the grid. Most of the 250 MW the plant uses is for rectification, 138,000 volts is transformed and rectified down to 400 volts DC The 400 VDC at 130,000 amps goes through 140 cells (car sized batteries) called cell lines, there are 4 of them, where Brine (saltwater) is put into the cells and chlorine, cell liquor (weak caustic) and Hydrogen are produced and sent on for further processing. Sorry for being long winded but i find it interesting that our process starts with salt water.
The final product is VCM which is used to make PVC pipe and is also used a lot by the auto manufacturing industry. I've been working for this company for 14 yrs, i can retire in 10 but plan on staying 20, i work 4 10 hour day weeks so i'm off Friday, Saturday, Sunday and get lots of vacation so DW and I have plenty of time and money to camp.
Dw stayed home and raised our daughter who has given us a 4 yr old grandson and a 1 yr old granddaughter, grandkids are the best! Now DW main responsibility is telling me how to drive and what not to eat, she's really good at her job :-).
