2nd, the measure that gas is escaped in acid water is controlled
The corporate boss will process sour crude, and sulfide content is high in acid water, while be influenceed by acid water band hydrocarbon etc., make
It is complicated to obtain gaseous component in sour water tank.Table 1 is the analyze data of gas in sour water tank.
Gas forms in the sour water tank of table 1
| Methane | Ethane | Ethene | Propane | Propylene | C4 | C5 | CO2 | N2 | CO | H2 | H2S |
| 3.01 | 2.49 | 2.18 | 1.60 | 4.39 | 2.86 | 0.65 | 0.85 | 43.84 | 0.05 | 4.92 | 33.13 |
From table 1 it follows that H in acid water head space gas2S volume fraction is 33.13%, and hydro carbons volume fraction is
17.18%.Therefore need to use corresponding measure, control sour water tank pressure is run in acceptability limit, and major measure has：
(1) operation of degassing tower is optimized
The acid water that upstream is come carries substantial amounts of H2S, lighter hydrocarbons and NH3Etc. component, if being fed directly to sour water tank, in normal pressure
Sour water tank in flashed, sour water tank pressure rise can be caused, therefore degassing tower is set before acid water enters tank.Low pressure is high
Temperature is advantageous to flash, therefore need to control the operation of degassing tower.Degassing tower Stress control is more low better, as long as after meeting flash distillation
Gas the pressure of pressure is removed to low pressure flare (back pressure 30kPa) after treatment tank, i.e., control is 35~40kPa；In addition, carry
The temperature that height enters degassing tower is also beneficial to improve degasifying effect, therefore heat exchanger is set up before acid water enters degassing tower, is improved de-
Gas tower temperature degree, improve degasifying effect.
(2) sour water tank temperature is controlled
Influenceed by outside air temperature change, the acid water of high concentration and the volatile component of gas phase balance in sour water tank.When outer
After boundary's temperature rise, the gas flow increase of flash distillation in sour water tank so that sour water tank pressure rise.Temperature Change is to acid water
The escape of gas is had a major impact in tank, and for temperature effectively in control sour water tank, FBT complex heat-preservations are smeared in sour water tank top coat
Material (insulating rare earth composite material), under the conditions of year-on-year, not smearing gas pressure in the sour water tank of FBT materials reduces
2kPa, its significant effect.
(3) to carrying out oil removing in sour water tank
Influenceed by temperature, the rise of sour water tank top pressure removes H2Outside S volatilization, the oil reservoir of the acid water A tank decks of static oil removing
Also can volatilize, predominantly C5And above component.Tank deck should also carry out regular oil removing in addition to FBT materials are smeared to acid water A tanks,
Ensure static oil removing pot A tank deck oil-frees.
3rd, the application of acid water head space gas processing system
Using " sour gas-water ring vacuum pump (boosting)-water scrubber (removing ammonia)-amine washes tower and (removes H2S)-low pressure gas torch
After the handling process of pipe network ", NH is realized3、H2The classification disposal of S and hydro carbons.NH3Postpone, pass through into stripper, Sulfur recycling installment
" burning ammonia " generates N2；H2S enters solvent regeneration system with amine liquid, realizes S recovery；After hydro carbons enters low pressure gas torch pipe network,
Upgrade for Dry Gas Desulphurization Unit is sent into after the recovery of gas holder compressor, efficiently separating for different component is completed, realizes preferable environmental protection
And economic benefit.H2S contents 33.13%Flow 43m3/ h (standard state) acid water head space gas enters the processing system
Afterwards, related data is to such as shown in table 2~3.
The water scrubber of table 2 runs relevant parameter
The amine of table 3 washes tower operation relevant parameter
As can be seen that acid water head space gas is after water ring vacuum pump boosts from table 2 and table 3, feeding is washed through washing and amine
H in the gas of low pressure flare system2S volume fractions are down toAmmonia volume fraction is down toDesulfurization and deamination positive effect.After the system comes into operation, the sour gas in sour water tank is no longer removed to chimney
Pressure, sulfur recovery facility chimney SO2On-line analysis data are decreased obviously.As shown in Figure 3.
As can be seen from Figure 3：From after acid water head space gas processing system comes into operation in time, after the boosting of acid water head space gas body
To flare discharge, sour water tank pressure on top surface stablizes the fluctuation in 1.5~2.5kPa, reducing tank deck pressure；Sour water tank
After top gas does not remove pressure to sulphur chimney, sulphur flue gas SO2Concentration of emission (CEMS online datas) is by original 270mg/m3It is down to
200 mg/m3, effectively prevent sour water tank pressure and the big amplitude wave of smoke stack emission caused by sour water tank removes pressure to chimney
It is dynamic.
