Abstract

A clapboard rectification tower for separating mixed fractions of C8-C11 normal alkanes, relates to a clapboard rectification tower structure, a vertical clapboard is arranged in the middle of the cavity, and the cavity is divided into four part, the partition includes spacer A (11) and spacer B (37), the lower part of one side of spacer A (11) is in contact with the upper part of one side of spacer B (37), gear A (16) and tooth A (15) Engagement, gear B (34) and teeth B (35) are engaged; the present invention sets the separator as a retractable structure, so that the present invention can account for various n-alkanes in the C8-C11 n-alkane mixture The difference in the ratio adjusts the size of the spaces of the four sections, and the floating packing layer A and the floating packing layer B are located in different sections according to the needs, and the purpose of fine fractionation is achieved.

Description

technical field

[0001] The invention relates to a structure of a clapboard rectification column, in particular to a clapboard rectification column used for the separation of C8-C11 normal paraffin mixed fractions. Background technique

[0002] Most of the mixed fractions contained in Fischer-Tropsch synthetic oil include C8-C20 n-paraffins. In industrial production, distillation cut fractions or multiple vacuum distillations are mainly used to extract n-paraffins in Fischer-Tropsch synthetic oil. When the separation section is a mixture of C8-C11 n-paraffins, multiple conventional rectification towers are required to be connected in series. In order to realize the preparation of high-purity n-paraffin products, it not only requires high equipment investment costs, but also requires a large area, and because of low thermal efficiency, it leads to high energy consumption. Now, partition rectification towers are often used for separation. The design of clapboard rectification ...
