Description
Technical field
The present invention relates to a kind of biology inhibition technology of administering the secondary hydrogen sulphide of crude oil gathering system, be applicable to crude oil gathering system unit such as suppressing individual well, petroleum transferring station, multi-purpose station by the secondary hydrogen sulphide of sulfate reducing bacteria biological metabolism effect, belong to the oil gas field toxic and harmful and administer the field.
Background technology
With regard to petroleum industry, H
2The distribution of S gas is very extensive, and is very harmful to employee's life security and health of human body.(50～200ppm) time,, the body tube is poisoned because of anoxic when concentration of hydrogen sulfide is higher with the oxygen that seizes in the blood; And very high concentrations (700～2000ppm) time, only need a few second people will lose self-saving ability, as untimely rescue with death.
The crude oil gathering system hydrogen sulphide overwhelming majority is a biogenesis, and under the condition that has sulphate to exist, sulfate reducing bacteria can move and collect in the defeated process by reduction and generate secondary hydrogen sulfide gas at crude oil.The equation of its biological chemistry action is as shown in the formula (II):
∑CH+CaSO
4→CaCO
3+H
2S+H
2O (II)
In mechanism, microorganism (sulfate reducing bacteria) only is incorporated into the sulphur of sub-fraction metabolism in the cell, most of sulphur (with the form of similar oxygen) is absorbed by aerobe (sulfate reducing bacteria of another kind) finishes energy metabolism, produce a large amount of accessory substances simultaneously, i.e. hydrogen sulphide.
Improvement technology to gathering system sulfate reducing bacteria generation hydrogen sulphide mainly contains two classes at present, one class is to kill sulfate reducing bacteria in the system of removing by add chemical bactericide in gathering system, but long-term the use pollutes environment easily and causes the human injury, and bactericide use for a long time can make the sulfate reducing bacteria in the system produce drug resistance, and germicidal efficiency will reduce along with the increase of filling time; Another kind of is passive processing mode, promptly the hydrogen sulphide that has produced is handled by modes such as physics, chemistry, microorganisms, as burning behind the hydrogen sulphide that produces in charcoal absorption hydrogen sulphide technology, hydramine method absorbing hydrogen sulphide technology, bio-trickling filter adsorption of hydrogen sulfide technology, the gathering system etc.More than two class technology all are hydrogen sulfide gas control technologys, can not in use can produce pollutant from solving the generation of hydrogen sulphide in essence, bring secondary pollution, now advocate to be adopted.
Summary of the invention
The generation of the secondary hydrogen sulphide of control sets communication system the objective of the invention is to start with from the bio-metabolic process source, utilize the present invention can realize that the source that generates hydrogen sulphide from the gathering system sulfate reducing bacteria is controlled, make the crude oil gathering system concentration of hydrogen sulfide reach (GBZ2-2002) the maximum permissible concentration 10mg/m of regulation of present national standard " workplace adverse factor occupation exposure limit "
3Requirement, eliminate the potential safety hazard of gathering system hydrogen sulfide gas to human body harm, reduce the corrosiveness of hydrogen sulphide to pipeline, realize that people-oriented, improves crude oil gathering system operation place working environment, and have important society, environment, economic benefit.
Crude oil gathering system sulfate reducing bacteria of the present invention generates the biological inhibition method of secondary hydrogen sulphide, and its crude oil gathering system sulfate reducing bacteria generates secondary hydrogen sulphide biostatic agent and is made up of 40-60mg/L natrium nitrosum, 25mg humic acid, 10-20mg/L Boratex, 20-30mg/L sodium hydroxide electrolyte, 95mg/L glutaraldehyde bactericide;
