Is the overall product yield of the catalytic cracking unit the main factor influenced by the adjustment parameters of the reaction section?

The operation of the anti-reformation system has the greatest impact on the total liquid yield of the catalytic cracking unit. The influencing factors include: catalyst activity, catalyst-to-oil ratio, reaction temperature, reaction pressure, properties of the feedstock, carbon content in the regenerant, use of terminators, efficiency of the settler and centrifuge, and stripping efficiency in the stripper section of the settler, among others. The reaction converts the raw materials into reaction oil and gas, which then enter a distillation and absorption stabilization system to further separate out target products such as liquefied gas, gasoline, and diesel. They also have an impact on the total liquid yield, but the key lies in the reaction stage – if the reaction system does not function properly or reacts excessively, no additional product will be generated regardless of how much effort is put into the subsequent stages.

The overall yield of products from a catalytic cracking unit is determined by the control parameters in the reaction section; any factor that affects this section will impact the yield. There are many such factors, and since the processes and equipment vary from one unit to another, optimization can only be achieved by examining the specific conditions of each unit, without trying to apply generic solutions~~~~~~~~~

The reaction unit is very important for catalytic cracking units; it is necessary not only to ensure the overall yield of products but also to coordinate with the unit’s production plan – if a diesel production plan is in use, the total liquid yield should not be increased to the maximum extent possible

The overall catalytic yield is primarily influenced by the reaction operating conditions, with factors affecting the reaction including catalyst activity, the properties of the feed oil, reaction temperature, reaction pressure, reaction time, the ratio of catalyst to oil, and the carbon content in the regenerator. However, the separation precision of the distillation system cannot be ignored either. The amount of light oil carried away by the slurry discharge is no small figure at all. Stabilizing the loss of components above C2 in the dry gas of the system reduces the yield of liquefied gas. To increase the overall yield, it is necessary to optimize production and ensure stable operation.

Those upstairs have provided a fairly comprehensive overview. The level of total liquid yield is highly dependent on factors such as the individual units used, the properties of the raw materials, and the production plans; it is also closely related to the operations in areas such as reaction, distillation, and stabilization. Although it is primarily determined by the reaction processes

The reaction is yield, and distillation stability is recovery. No matter how much is produced, it’s useless if it can’t be retrieved ； Of course it needs to be taken back; first, it has to be produced.

The factors affecting the total liquid yield in a catalytic cracking unit include: catalyst activity, catalyst-to-oil ratio, reaction temperature, reaction pressure, feedstock properties, carbon content in the regenerator, space velocity, and so on. Target products such as liquefied gas, gasoline, and diesel are obtained through reaction, distillation, and absorption stabilization systems. The key lies in the careful operation of the reaction unit and proper control of various process parameters, so that by-products can be kept under control. Secondly, it is necessary to optimize the production process……
