Abstract
The invention relates to application of glacial acetic acid serving as a demulsifying product, in particular to application of glacial acetic acid in sump oil and aged oil processing. The invention has the beneficial effects that the water content of separated crude oil subjected to glacial acetic acid is measured by a water content measurement method in crude oil according to Petro China industrial standard SY/T5280-2000 and is reduced to below 1.5%, thereby achieving an oil handing standard. The glacial acetic acid has low harmfulness on operation staff and has the characteristics of low cost, high economic benefits and the like, and is the extremely good demulsifying product for processing the sump oil and aged oil.
Description
Technical field
The present invention relates to the application of glacial acetic acid as the breakdown of emulsion goods.
Background technology
The production capacity of Feng Cheng working district is progressively enlarging at present, yet crude oil water containing rises and other complexcase cause the exploitation difficulty of oil and natural gas constantly to increase, and production efficiency constantly reduces.Be converted into ageing oil and exploit quite a few crude oil of ground because of a variety of causes, can not use, cause energy dissipation, and environment is caused severe contamination.For example: oil well pipe leaks outside and other ground crude oil, the well workover waste liquid, the sump oil of discharging after emulsion that the emulsified crude oil that added various chemical agents that sewage accident pool, waste disposal plant reclaim, crude oil treating device are discharged and the various operations of oil well, clear jar of jar end sump oil or the like, ageing oil intractability large period is long, at present wind city ageing oil is given environmental protection company of Karamay City BDCom in the mode of waste and is handled, only the Feng Cheng working district pay BDCom every year the sump oil handling just up to surplus 400 ten thousand yuan.Therefore wind city ageing oil breakdown of emulsion recovery secondary uses will become to preserve the ecological environment and improve output and has important practical significance.Zoogloea is bred and formed to sulphate reducing bacteria fast in the ageing oil, stick together with polymkeric substance, oil colloid, bituminous matter etc., ageing oil and fresh crude oil combination treatment have seriously been disturbed the normal operation of dewatering system in the master's technical process of Feng Cheng working district, or cause that outer output oil is moisture to exceed standard, the difficult ageing oil that reclaims of part can only be deposited in the greasy filth pond or landfill disposal, and water, the edatope in zone caused severe contamination.Along with the progressively increase of the special heavy oil production in Feng Cheng working district, the quantity discharged of ageing oil and sump oil also can increase.Therefore, ageing oil has become the important factor of restriction Feng Cheng working district safety in production and environment protection.How to solve Feng Cheng working district ageing oil, just seem particularly important.
The method of breakdown of emulsion generally comprises the method for physics and the method for chemistry, usually in order to overcome the obstacle that is caused by liquid film, combine two kinds of methods.Usually physical method comprises the high-voltage electric field breakdown of emulsion, hot breakdown of emulsion, center of gravity and centrifugal settling breakdown of emulsion.Chemical demulsification is by adding chemical agent, and part is replaced the natural active matter on the liquid film, destroys liquid film and makes the drop flocking settling, realizes oily water separation.Sump oil and ageing oil milk sap are the mixed dispersions of emulsification type complexity, are made up of dissimilar milk sap such as W/O, O/W and multiple emulsifications, and emulsified state is stable.The existing conventional emulsion splitter is not good to this milk sap treatment effect, and dewatering efficiency is lower, and cost is higher.
Summary of the invention
At above-mentioned defective, the purpose of this invention is to provide of the application of a kind of glacial acetic acid as the breakdown of emulsion goods.
Described application is the application of glacial acetic acid in sump oil and/or ageing oil processing.
The purity of described glacial acetic acid is more than 99%.
Glacial acetic acid is added in sump oil and/or the ageing oil, and making the concentration of glacial acetic acid in mixture is 500ppm～2000ppm.
Glacial acetic acid is added in sump oil and/or the ageing oil, and making the concentration of glacial acetic acid in mixture is 1000ppm.
Described breakdown of emulsion goods are that glacial acetic acid is mixed use as the independent use of emulsion splitter or with auxiliary agent.
The quality percentage composition of glacial acetic acid in the breakdown of emulsion goods is 20%～100%, and all the other are auxiliary agent.
Described auxiliary agent is one or more in 926B type inhibiter, methyl alcohol, the DY201 type emulsion splitter.
Glacial acetic acid adds auxiliary agent when using as the breakdown of emulsion goods, can make it reach better effect.Have the preservative activity of the line equipment of keeping the scene intact as 926B type inhibiter, methyl alcohol has antifreezing effect, adds DY201 type emulsion splitter and adds according to special sump oil situation.
Experimental study shows that glacial acetic acid is when handling sump oil, ageing oil, after glacial acetic acid and sump oil, ageing oil mixed, be placed in the water-bath 90 ℃ of constant temperature, after the sedimentation in sump oil, the ageing oil contained water, silt impurity and crude separation come out, according to the industry standard SY/T5280-2000 of PetroChina Company Limited. crude oil water containing assay method (distillation method), the crude oil water containing that mensuration is separated can be reduced to below 1.5%, reaches the friendship oil standard.Glacial acetic acid endangers low to operator, have with low cost, the high characteristics of economic benefit, is a kind of extraordinary breakdown of emulsion goods of handling sump oil, ageing oil.
