• 35 increase the amount of consumption of the mixture of the product mass and the acid, that is, it means significantly increase the value of the consumption of the ratio of the consumption of the mixture
• the sizes of the slit-like slit and, first of all, the length of its slit lengths are limited by the conditions for the equilibrium of the flow of the mass through the slit cross-section. If the gap is too large. a wide, well-defined path of the mass at the site. The rates are much higher than at the beginning of the battle. If the gap is too large, then it’s most likely that the load will increase at the beginning of the burst if it rises from the load. In this case, there may be a place for clogging of the slit-like sorbent with the mass of the c. As a result, the aggregate of the unit will be washed out by the kyrielod stream and keep it lowered. -
