Description
Technical field
The present invention relates to HYCO systems, and the System and method for of emptying is reduced more particularly, to a kind of HYCO ice chest.
Background technique
Currently, HYCO device is mainly by raw material (54% CO, 45% H2And micro N2、CH4, Ar) and pass through height
Pressure CO becomes low pressure CO throttling expansion refrigeration, liquefies into ice chest, different using each gas boiling point, gradually removes and can allow CO
And H2, CH4, N2, Ar passes through.Final products are H after purifying2Client is given with CO product.
And since the component in HYCO device in raw material is relatively fixed, H2The ratio of product and CO product is relatively fixed.
HYCO ice chest can be used to separate production H2Product and CO product.
HYCO steam reformer device is single fixed production H2Product.
If the H that HYCO ice chest is separated2Product and CO product are both supplied to single client A.And client A in order to avoid
Unnecessary emptying, thus can be automatically by CO and H2Demand is fixed on 54%:45% or so.By HYCO ice chest and HYCO steam
Conversion furnace apparatus is used cooperatively, and can satisfy client for CO and H2The requirement of demand percentage, therefore, the HYCO of such case are cold
There is a situation where torch of setting fire is extremely rare for case.
And if the H that HYCO ice chest is separated2Product and CO product are respectively supplied to different clients, for example CO product is
Supply client B, and H2Product is then supply client C.Client B and client C is only to obtain product according to the demand in downstream.
HYCO ice chest major part situation under so this relation of the supply is can not to match CO and H2For 54%:45% ratio.To
Leading to part-time is CO emptying burning, or is H2Emptying burning.
Continuing this state is the loss to using energy source.Related document, which is also mentioned, can guide to HYCO for remaining production capacity
Steam reformer device is as fuel combustion.But HYCO ice chest CO emptying and H2Emptying is not timing, fuel value fluctuation
It is very big, it is not appropriate for the furnace temperature and negative pressure of control HYCO steam reformer.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of HYCO ice chests to reduce
The System and method for of emptying.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of system that HYCO ice chest reduces emptying, including the first HYCO ice chest, the 2nd HYCO ice chest and HYCO steam turn
Change furnace, the product H that the first HYCO ice chest generates2It is supplied to client C, the products C O of generation to pass through by the first hydrogen gas lines
First CO pipeline is supplied to client B, the product H that the 2nd HYCO ice chest generates2Client is supplied to by the second hydrogen gas lines
The CO of A, product are supplied to client A, the product H that the HYCO steam reformer generates by the 2nd CO pipeline2Pass through third hydrogen

Draw the newly-increased hydrogen gas lines for being connected to the second hydrogen gas lines.
The first CO pipeline is equipped with the first CO product regulating valve and the first CO product stream meter；The 2nd CO pipe
Line is equipped with the 2nd CO product regulating valve and the 2nd CO product stream meter；It is flowed to by product, described newly-increased CO pipeline one end is set
It sets before the first CO product regulating valve, the other end is arranged before the 2nd CO product regulating valve.This structure setting sufficiently avoids wealth
Business dispute.
First hydrogen gas lines are equipped with the first hydrogen product regulating valve and the first hydrogen product flowmeter；Described
Two hydrogen gas lines are equipped with the second hydrogen product regulating valve and the second hydrogen product flowmeter；It is flowed to by product, it is described newly-increased
Hydrogen gas lines one end is arranged between the first hydrogen product regulating valve and the first hydrogen product flowmeter, and the other end is arranged second
Between hydrogen product regulating valve and the second hydrogen product flowmeter.This structure setting sufficiently avoids financial dispute.
Newly-increased CO regulating valve, newly-increased CO check valve and newly-increased CO are set gradually by product flow direction on the newly-increased CO pipeline
Product stream meter.The flow of client A can be removed with the control of system, while client's A pipe network being avoided to flow backward to the first HYCO ice chest.
In the newly-increased hydrogen gas lines by product flow direction set gradually newly-increased hydrogen regulating valve, newly-increased hydrogen check valve and
Newly-increased hydrogen product flowmeter.The flow of client A can be removed with the control of system, while client's A pipe network being avoided to flow backward to first
HYCO ice chest.
The third hydrogen gas lines are equipped with third hydrogen product regulating valve and third hydrogen product flowmeter.
The pipeline that the first CO pipeline, the 2nd CO pipeline, newly-increased CO pipeline are 6 cun；First hydrogen gas lines, second
The pipeline that hydrogen gas lines, third hydrogen gas lines, newly-increased hydrogen gas lines are 3 cun.
It realizes the method that HYCO ice chest reduces emptying, when client's B CO usage amount is reduced, will be increased newly on newly-increased CO pipeline
CO regulating valve, newly-increased CO check valve are opened, and are sent to client A outside, until the CO product of the first HYCO ice chest is not vented, are reduced simultaneously
The load of 2nd HYCO ice chest improves HYCO steam reformer load, so that material balance, is not vented；
When client's C hydrogen product usage amount is reduced, by newly-increased hydrogen regulating valve, the newly-increased hydrogen in newly-increased hydrogen gas lines
Check valve is opened, and is sent to client A outside, until the hydrogen product of the first HYCO ice chest is not vented, while reducing the conversion of HYCO steam
Furnace load, so that material balance, is not vented.
The operation principle of the present invention is that:
1, the first HYCO ice chest, the 2nd HYCO ice chest and HYCO steam before the newly-increased CO pipeline that comes into operation, newly-increased hydrogen gas lines
Vapour reburner has operated normally.
2, hydrogen regulating valve is increased newly, newly-increased CO regulating valve debugging finishes.Newly-increased CO product stream meter, newly-increased hydrogen product stream
Meter debugging finishes.
3, after the CO dosage of client B is reduced, emptying is generated.Newly-increased hydrogen regulating valve valve is then slowly opened, simultaneously
The load of the 2nd HYCO ice chest is reduced, HYCO steam reformer load is increased, keeps H2It is constant to send client's A total amount outside.
4, in the H of client C2After dosage is reduced, emptying is generated.Newly-increased CO regulating valve is then slowly opened, is reduced simultaneously
HYCO steam reformer load keeps H2It is constant to send client's A total amount outside.
Compared with prior art, the invention has the following advantages that
One, HYCO ice chest deisgn product CO and product H2Purity it is all identical.Requirement suitable for each client.
Two, CO is efficiently solved2Discharge, makes full use of the energy.
Three, fairness: before being mounted in flowmeter due to pipeline, client is not had an impact.
Four, safe and reliable: after HAZOP is analyzed, to install check valve additional, and increase pressure difference interlocking.Avoid pipeline from coming into operation with
The risk of adverse current is generated afterwards.
