Description
Technical field
The present invention relates to a kind of crude oil desalting composition, its preparation method, and use this desalting composition to carry out crude oil, the especially method of acid-containing raw oil desalination.
Background technology
The existence meeting of salt causes corrosion to the equipment that comprises atmospheric tower in the crude oil, thereby generation has a strong impact on to following process.Therefore, must just these salt be removed in the electric desalting stage.
Technology of electric de-salting is a kind of conventional means that removes salt in the crude oil.This method adopts the method for electricity, heat, chemical means associating breakdown of emulsion (promptly by adding suitable emulsion splitter, under certain temperature, current field condition, make oil-water mix the effective breakdown of emulsion of formed water/oil emulsion), realize oil, water sepn, thereby reach the purpose that removes salt and moisture content in the crude oil.
The selection of emulsion splitter and use are to influence one of important factor of crude oil desalting, dehydrating effect.The emulsion splitter that uses of this field is third generation emulsion splitter now, and its main component is the polymer nonionic surface active agent, for example the oxyethane propylene oxide block copolymer.
People have now found that, only use emulsion splitter to exist the problem that can not reach oily water separation effectively in technology of electric de-salting.Especially for acid-containing inferior petroleum crude, use emulsion splitter to carry out desalting and dewatering merely and be difficult to make the quality of processing back product to be satisfied the demand.Simultaneously, when in desalinating process, using emulsion splitter merely, do not reach requirement, also can cause the phenomenon of electric current rising, loss of voltage in the technology of electric de-salting to take place as its demulsification, when serious even can cause and to power, thereby have a strong impact on the normal operation of technology of electric de-salting.
Summary of the invention
The invention provides the desalting composition of a kind of crude oil, especially acid-containing raw oil.Said composition comprises the following component of representing with mass percent:
