Answering still R6102 blocked operation, raw material carries out reacting required heat in a kettle. to be provided by adding vapours, reaction temperature
Degree is by adding the amount of vapours to regulate control；
3) material after having reacted is got from reactor through the first elevator pump P6102 and is entered into the first plate column
In T6201, the light component in material is discharged from the tower top of the first plate column T6201, and sequentially passes through the first condenser
E6202, the first cooler E6203 carry out condensing cooling down operation, flow into afterwards in the first return tank V6201, pass through
First reflux pump P6202 gets from the first return tank V6201, and a part returns to the first plate as overhead reflux liquid
In formula tower T6201, remainder is then as the extraction of light component product 1, and the heavy constituent in material is at the first plate column T6201
Tower bottom through reboiler E6201 heat to evaporate light component further, heat is provided simultaneously, is deposited on the first plate
The tower bottoms of formula tower T6201 tower bottom is in the second elevator pump P6201 gets entrance packed tower T6301；
4), after entering in packed tower T6301 after the tower bottoms metering of T6201, the relatively low light component of boiling point is from filling out
The tower top of material tower T6301 is discharged, and sequentially passes through the second condenser E6301, the second cooler E6302 carries out condensing cold
But operate, flow in the second return tank V6301 afterwards, by the second reflux pump P6302 from the second return tank V6301
In get, a part return in packed tower T6301 as overhead reflux liquid, remainder is relatively low as boiling point
Light component product 2 extraction, be deposited on the of a relatively high tower bottoms of the boiling point bottom packed tower T6301 through the 3rd lifting
Pump P6301 gets in entrance the second plate column T6501；
5) after entering in the second plate column T6501 after the tower bottoms metering that boiling point is of a relatively high, at vacuum pump set C6501
Under the vacuum condition provided, light component is discharged from the tower top of the second plate column T6501, sequentially passes through the 3rd condenser
E6501, the 3rd cooler E6502 carry out condensing cooling down operation, flow in the 3rd return tank V6501 afterwards, pass through
3rd reflux pump P6501 gets from the 3rd return tank V6501, and a part returns to the second plate as overhead reflux liquid
In formula tower T6501, remainder, as the extraction of light component product 4, is deposited on the second plate column T6501 tower bottom
Tower bottoms is discharged from tower bottom as final component product 3.
3rd step, designs equipment site plan and the equipment facade layout drawing of this chemical equipment technology checking maintenance device,
As shown in Figure 2 and Figure 3.
4th step, according to the structural representation of tower chemical industry equipment as Figure 4-Figure 6, improves into and meets what chemical process required
Information drawing.
5th step, designs device frame platform, as shown in Figure 7.
The installation of the 6th step, craft piping and field instrument.Will be each according to the Flow Diagram for Chemical Process of design in second step
Connect into perfect technological process with chemical pipeline between chemical industry equipment, between chemical pipeline and chemical industry equipment, use flange even
Connecing, the pipe fitting in pipeline such as elbow, threeway etc. use and are welded to connect, and the valve in pipeline is according to selected valve kind
Class is respectively adopted welding or threaded, and the instrument in pipeline is respectively adopted welding according to selected different types of instrument
Or it is threaded；Work progress should strictly be carried out by the various job specfications of chemical plant installations, it is ensured that device and actualization
Work process units is as good as.
In this technological process, divided by the first plate column T6201, packed tower T6301 and the second plate column T6501
For the Light ends obtained is in accordance with the relative height of boiling point with heavy constituent, tower bottoms i.e. boiling point is of a relatively high
Heavy constituent, the tower bottoms in the first plate column T6201 is separable into packed tower T6301 after entering packed tower T6301
Tower bottoms at the bottom of the light component of tower top and packed tower T6301 tower, the tower bottoms in packed tower T6301 is entering the second plate
