If the raw materials remain unchanged in a catalytic unit and only the processing volume is altered, and if the product quality is to be maintained at an acceptable level, is it necessary to change the temperature at which the product is extracted?
343. What impact do other positions have on the distillation position? (1) Reaction depth. (2) Total reaction feed amount. (3) An accident occurs in the reaction. (4) The amount of reaction stripping steam and other steams (such as emergency steam) directly affects the liquid level in the overhead oil-gas separator, as well as the dry point of the crude gasoline. (5) Reaction temperature. (6) Abnormal operation of the gas compressor affects the pressure in the distillation tower. Large fluctuations affect the operation of the entire tower and the quality of the product, as well as the reaction process. (7) When the condensate oil from the reabsorption tower is sent to the vapor-liquid separator at the top of the tower, it affects the liquid level in the container (in some systems, it is sent to the distillation tower) as well as the pressure in the distillation tower. (8) Piling the flare into the condensed oil affects the liquid level of the overhead gas-liquid separator and the pressure in the fractionation tower. (9) Malfunction of the absorption stabilization system affects the outlet of crude gasoline, the reflux rates and temperatures at the first and second stages, as well as the amount of rich absorbent oil in the reabsorption tower and the pressure in the distillation tower.
Could you explain the processing volume in more detail? With all other conditions remaining unchanged
As the processing volume increases, it is necessary to maintain a heat balance within the distillation tower; in particular, the extraction temperature must remain constant. Adjusting the amount of material returned to the tower from various side streams is required to ensure product quality
