What is it the common system in order to avoid any fire in the coke pad, coke pit or even belt conveyor when producing shot coke ? Our refinery in the past only produced sponge coke. Nowadays, we are changing the crude oil and we are producing shot coke. We are worry about our safety system in all handling and storage coke area. What is it the safety device necessary to shot coke ? Which protection do I need for the belt conveyor ? And for the coke pit and coke pad ?
My opinion is that the first thing to ensure as far as possible is the cooling/quenching of the shot coke; that is, reviewing whether the cooling/quenching ramps are consistent with this type of coke, usually is recommended at the end of the cooling, leave for a short period of soaking this type of coke
At least in one of ours units we had to change the material of the belts by one that can resisted more temperature and hydrocarbon ; also will check that the fire system cover the pit in case of any fire in that zone and finally with this type of coke in some opportunities we had some fire in the storage/pile and this was to handle, spray the coke with a product/chemical that is called Soil Cement. This product creates a film over the coke ; preventing that the coke was in contact with air and also preventing the coke fine fly from the storage pile due to the wind
