You calculate the amount of carbon in the Kgs of Hydrocarbon using Carbon Number and find out the moles of the carbon. Divide the moles of steam by the moles of carbon to get steam carbon ratio. For further accurate calculation one can also take into account the excess hydrogen coming from the feed preparation section and subtract that during calculation
