Abstract
The utility model relates to a kind of butylene concentrate raw material preheating system.Mainly solved that the material temperature existing in prior art is low occurs that feed separation weak effect causes the butylene of product to lose large problem.It is characterized in that: on the not anti-carbon four supplied materials pipelines (2) between described feed pump (7) and extraction tower (1), be connected heat exchanger (3), not anti-carbon four supplied materials in described not anti-carbon four supplied materials pipelines (2) are walked heat exchanger shell pass, described heat exchanger (3) also connects lean solvent supplied materials pipeline (5) and lean solvent feed back pipeline (4), and lean solvent is walked tube side; On described lean solvent supplied materials pipeline (5), be connected to internally piloted valve (6); On not anti-carbon four supplied materials pipelines (2) between heat exchanger and extraction tower (1), establish temperature thermocouple (8).This butylene concentrate raw material preheating system, can improve and stablize the temperature of controlling charging, thereby improves the separating effect of material in tower, and the loss of product butylene is little, and can save the cooling water inflow of cooling lean solvent.
Description
Technical field
The utility model relates to a kind of pre-heating system in petrochemical industry, particularly a kind of butylene concentrate raw material preheating system.
Background technology
The hilllock charging of petrochemical industry methyl ethyl ketone plant butylene concentrate is the not anti-carbon four from tank field, through intermediate raw material tank again by feedstock pump to extraction tower charging.The material temperature coming due to outer net is low, and raw material is larger with variation of ambient temperature, and especially summer in winter, material temperature was poor very large.So always there will be in process of production the bad phenomenon of feed separation effect, cause the butylene loss of product larger.And lean solvent enters before extraction tower, need to be cooled to 50 ℃ by 100 ℃ of left and right, lean solvent cooler cooling load is larger, relatively wastes energy.
Summary of the invention
Technical problem to be solved in the utility model is to overcome that the existing material temperature existing in background technology is low occurs that feed separation weak effect causes the butylene of product to lose large problem, and provide a kind of butylene concentrate raw material preheating system, this butylene concentrate raw material preheating system, can improve and stablize the temperature of controlling charging, thereby improve the separating effect of material in tower, the loss of product butylene is little.
The invention for solving the technical problem can reach by following technical solution: this butylene concentrate raw material preheating system, comprise extraction tower, described extraction tower middle part connects not anti-carbon four supplied materials pipelines, on described not anti-carbon four supplied materials pipelines, be connected to feed pump, on not anti-carbon four supplied materials pipelines between described feed pump and extraction tower, be connected heat exchanger, not anti-carbon four supplied materials in described not anti-carbon four supplied materials pipelines are walked heat exchanger shell pass, described heat exchanger also connects extractant lean solvent supplied materials pipeline and extractant lean solvent feed back pipeline, and extractant lean solvent is walked tube side; On described lean solvent supplied materials pipeline, be connected to internally piloted valve; On not anti-carbon four supplied materials pipelines between heat exchanger and extraction tower, establish temperature thermocouple.
The utility model is compared and can be had following beneficial effect with above-mentioned background technology: this butylene concentrate raw material preheating system, owing to adopting above-mentioned flow process, can improve feeding temperature, is conducive to feed separation and has improved product yield, has reduced loss.Utilize the heat that originally needs cooling unnecessary extractant, thereby reduced the cooling water flow of cooling extractant, improved energy-saving effect.
accompanying drawing explanation:
Accompanying drawing 1 is structural representation of the present utility model.
In figure: 1-extraction tower, the not anti-carbon four supplied materials pipelines of 2-, 3-heat exchanger, 4-lean solvent feed back pipeline, 5-lean solvent supplied materials pipeline, 6-internally piloted valve, 7-feed pump, 8-thermocouple, 10-lean solvent cooler, 11-lean solvent enters tower pipeline, 12-lean solvent cooler water-line, 13-lean solvent cooler return piping.
the specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this butylene concentrate raw material preheating system, comprise extraction tower 1, described extraction tower 1 middle part connects not anti-carbon four supplied materials pipelines 2, on described not anti-carbon four supplied materials pipelines 2, be connected to feed pump 7, on the not anti-carbon four supplied materials pipelines 2 of described feed pump 7 and 1 of extraction tower, be connected heat exchanger 3, not anti-carbon four supplied materials in described not anti-carbon four supplied materials pipelines 2 are walked heat exchanger shell pass, described heat exchanger 3 also connects lean solvent supplied materials pipeline 5 and lean solvent feed back pipeline 4, lean solvent is walked tube side, on described lean solvent supplied materials pipeline 5, is connected to internally piloted valve 6; On the not anti-carbon four supplied materials pipelines 2 that heat exchanger 3 and extraction tower are 1, establish temperature thermocouple 8, be used for measuring and control raw material C4 heating-up temperature; Described lean solvent feed back pipeline 4 connects lean solvent cooler 10, and described lean solvent cooler 10 enters tower pipeline 11 by lean solvent and is connected with extraction tower 1 tower top.Described lean solvent feed back pipeline 4 and lean solvent enter tower pipeline 11 and walk lean solvent cooler 10 shell sides.Described lean solvent cooler 10 also connects lean solvent cooler water-line 12 and lean solvent cooler return piping 13, and described lean solvent cooler water-line 12 and lean solvent cooler return piping 13 are walked lean solvent cooler 10 tube sides.
This butylene concentrate raw material preheating system, after C4 feed pump, before extraction tower, has installed a raw material heat exchanger 3.The thermal source of heat exchanger 3 is the lean solvents that loop back extraction tower at the bottom of butylene tower stripper tower.Lean solvent is walked tube side, with internally piloted valve 6, regulates extractant to add heat flow; The not anti-carbon four of raw material is walked shell side.On C4 pipeline after heating, set up temperature-measuring heat couple, be used for measuring and control raw material C4 heating-up temperature.
This butylene concentrate raw material preheating system, in grand celebration blue stone Co., Ltd when maintenance to the flow implementation of methyl ethyl ketone plant butylene concentrate unit feed native system.After going into operation, coming into operation of butylene concentrate feed preheater, has realized the feeding temperature that utilizes extractant waste heat to improve raw material, has increased gas-phase feed amount, has improved separating effect, makes yield improve loss and reduces, and has reached quiet run and energy-saving and cost-reducing object.
