Hi, if there are 11 Heat exchangers in unit 1, is it named E-1011 or E-111???

[@shoyunkaku]

I think it's E-111. The first 1 refers to area 100. If you write E-1011, means that the heat exchanger number 11 is in area 10.

[@wolvinification]

@@shoyunkaku So E-1121 would mean 121st heat exchanger in area 1 or 21st heat exchanger in area 11?

[@saintgrr]

@@wolvinification Well, if you need 121 heat exchangers, there's something weird in your process. The same for 11 areas, it'd be better to build another plant
