  • They use adiabatic coolers to minimize electrical cost for cooling and maximize cooling capacity. The water isn’t directly used as the cooling fluid. It’s just used to provide evaporative cooling to boost the efficiency of a conventional refrigeration system. I also suspect that many of them are starting to switch to CO2 based refrigeration systems which heavily benefit from adiabatic gas coolers due to the low critical temp of CO2. Without an adiabatic cooler the efficiency of a CO2 based system starts dropping heavily when the ambient temp gets much above 80F.

    They could acheive the same results without using water, however their refrigeration systems would need larger gas coolers which would increase their electricity usage.




  • Good thing it’s surrounded by water.

    Joking aside, if it didn’t burst into flames right away then it’s probably fine on the acetylene front. The main hazard of acetylene is just the insane flamability (explosive limits 2.5-100%). But it’s also very soluble in water and isn’t really harmful to the environment on it’s own. There are actually bacteria that can use it as a food source. So the acetylene is just going to be quickly disapated by the wind and disolved into the ocean where it’ll be broken down into harmless products.

    The bigger concern is that, with that much calcium carbide reacting, there was likely fairly substantial amounts of phosphine and arsine produced as well. Those are both pretty damn toxic. Normally the amount of both of those produced in a calcium carbide reaction is fairly small but when there are several shipping containers of the stuff reacting then those normally trace contaminants are likely going to actually amount to something.
