The adsorption separation device comprises an adsorption tower, a pretreatment tower, a first fractionating tower and a second fractionating tower, the adsorption tower sequentially comprises a desorption area, a refining area, an adsorption area and an isolation area from top to bottom, and the desorption area, the refining area, the adsorption area and the isolation area are each composed of a plurality of bed layers; the bed layer comprises a feed port, an extract port, a raffinate port, a reagent liquid adding port and a cleaning liquid port; and the feed port, the extract liquid port, the raffinate port, the agent liquid adding port and the cleaning liquid port between the bed layers are respectively connected through a multi-channel material distribution valve. By setting each bed layer of the adsorption tower and the connection relationship between the bed layers, low-temperature, low-pressure, non-hydrogen and pure physical adsorption separation and targeted separation processing are realized, the loss of high-quality components is avoided, and the adsorption separation effect is greatly improved; the multi-channel material distribution valve is applied to valve control of the adsorption tower, so that the number of external electromagnetic valves is greatly reduced.
Description
technical field [0001] The invention relates to the technical field of adsorption towers, in particular to an adsorption separation device based on a multi-channel material distribution valve and an adsorption separation process based on the adsorption separation device. Background technique [0002] In adsorption separation technology, simulated moving bed technology is a new and efficient technology. The simulated moving bed adsorption separation technology has the advantages of low investment, low energy consumption, easy large-scale operation, continuous operation, stable operation, high product purity, and high utilization efficiency of adsorbent. Separation of chemical products has been extended to biochemical, pharmaceutical and other fields. Especially with the trend of overcapacity in refining becoming more and more serious, the technology with the core appeal of "reducing oil and increasing production" has become the mainstream transformation and development direc...
