Problems solved by technology

The thermal combustion method usually needs to mix the odor with the fuel for thermal combustion. The disadvantage is that the upper and lower limits of the explosion need to be considered, the fuel consumption is large, and there is a tendency to be replaced by catalytic combustion.
The process of this method is relatively complicated, a special absorbent is required, and the purification effect on hydrocarbons is not ideal

Embodiment 1～3

[0022] Collect the tank top gas in the sour water tank area of ​​a petrochemical refinery, and connect it to a wet buffer gas tank, buffer for 0.5 to 1 hour, and keep the pressure at about 500-1000Pa to ensure the stability of the flow and pressure of the tank top gas before entering the treatment device , and remove 90% of the water vapor in the exhaust gas. Buffered acidic water tank head gas at 50-150Nm 3 / h gas flow into the desulfurization reactor, in the desulfurization reactor mixed with lye with a concentration of 8% to 10%, to remove H in the exhaust gas 2 S and other sulfur-containing pollutants, the resulting alkali slag can be directly discharged into the alkali slag treatment system in the plant area. After desulfurization, the exhaust gas passes through the buffer tank to remove the condensed water, and then enters the deoxidation reactor. Using Fe / Al 2 o 3 Deoxidizer, the temperature of the reaction process is controlled at about 150-200°C, the pressure is c...

Abstract

The invention relates to a treatment method of acid water head space gas. The treatment method comprises the following steps of: (1) collecting acid water head space gas; (2) introducing the collected acid water head space gas into an alkaline liquor desulfurizing device to remove sulfur-containing pollutants; and (3) feeding sulfur-removed waste gas into an oxygen removing device for removing oxygen therein, and feeding into a low-pressure gas pipe network of a refinery. Compared with the prior art, the treatment method has the advantages of simple entire process flow, low personnel management cost, no discharge of waste water or waste gas, direct feeding of waste residues into an alkaline residue treatment device in a factory, no increase in treatment cost, avoidance of secondary pollution and small device floor area.

Description

technical field [0001] The invention relates to a treatment method for acid water tank top gas, belonging to the technical field of environmental protection waste gas treatment. Background technique [0002] There will be volatilization of oil and gas in the process of storage, transportation, production and sales of oil products in refineries. As the sulfur content of processed crude oil continues to increase, the stench of volatile gas in sour water storage tanks in refineries is becoming more and more serious. Volatile gas contains a large amount of oil gas and high concentration of sulfide and other harmful gases. These gases have become an important source of odor pollution in oil refineries. If they are not treated, they will seriously pollute the environment and affect human health. Corrosion of equipment and waste of energy. [0003] The main pollutants in the sulfur-containing sewage tank are sulfur-containing compounds such as hydrogen sulfide and volatile hydroc...
