The present disclosure relates to a data processing method and apparatus based on a Merkel tree, the method optimizes the structure of the Merkel tree so that when generating a Merkel tree to be updated based on the original service data and inserting a new leaf node into the Merkel tree, no parent node is created for a leaf node without a sibling node and a non-leaf node without a sibling node; specially, when there is new service data, a corresponding new leaf node is created and inserted into the leaf node layer; if the new leaf node is located at an odd position in the leaf node layer, the non-leaf node layer does not need to be updated; if the new leaf node is located at an even position in the leaf node layer, a new non-leaf node is created and inserted into the non-leaf node layer.

Provided are a vacuum rectification tower with a satellite-type tower kettle and a vacuum rectification method for atmospheric pressure residual oil. The vacuum rectification tower includes a satellite-surrounded vacuum tower kettle and a rectifying section; the satellite-surrounded vacuum tower kettle includes a main tower kettle and a plurality of sub-reactors arranged outside the main tower kettle in a satellite-surrounded mode; the main tower kettle is provided with a first outlet and a plurality of spray inlets, and a top portion of the main tower kettle has an opening; the sub-reactor is provided with a second outlet and a first inlet, the spray inlets are connected with the second outlets of each sub-reactor in a one-to-one correspondence, and the first outlet is connected with the first inlets. The above vacuum rectification tower is used for treating the atmospheric pressure residual oil, and an extraction rate of light oil may be effectively improved under relatively mild temperature and pressure environment.
