Description
Technical field
The present invention relates to wet oil desalting and dewatering technical field, relate in particular to a kind of crude oil electro-desalting dehydrator based on two single-phase rectifier power supplys.
Background technology
At present; Two single-phase rectifier power supply AC and DC Double Electric crude oil electro-desalting dehydrators (that is: form two kinds of electric fields of AC and DC simultaneously with its unique AC and DC electric field electrode net distributed architecture characteristics in same electric desalting and dewatering device; Its self-cleaning oil quality of DC electric field is high; Alternating-electric field is limpid than the DC electric field dehydration, and both combine performance advantage separately), at home and abroad Petroleum and Petrochemical Industry obtains extremely widespread use; In conventional crude electrodesalting and electrodehydrating process, the performance important role.Yet; Industry spot is used and is shown that the AC and DC electric field power savings of this structure is remarkable, still; For extraordinary crude oil (as: highly aqueous, ageing oil, BO and high viscosity oil etc.); Its desalting and dewatering poor, that is: crude oil is deviate from oil length height in the water, and crude oil water content is high behind the desalting and dewatering.In addition, be the crude oil water content behind the reduction desalting and dewatering, the field operator strengthens electric field; But caused the alternating-electric field between positive electricity polar net and the ground strong excessively; Electric current is excessive, occurs exchanging a series of faults such as " electric fields " easily, behind the long-play; A certain electrode network often takes place damage phenomenon, and DC electric field still makes a little less than very the crude oil water content behind the desalting and dewatering still be difficult to satisfy water content requirement.Thereby this AC and DC Double Electric crude oil electro-desalting dehydrator can't the on-the-spot use even inactive in the oil field.
U.S.'s patent of invention (patent No. 3773180) and document (Zhang Hongren; Crude oil dehydration, petroleum industry press, 1990) provided AC and DC Double Electric crude oil electro-desalting dehydrator power supply architecture and principle shown in Fig. 1 (a); Wherein, 1 one step-up transformers; 2 one high-voltage rectifiers; 3 one positive electricity polar nets; 4 one negative electricity polar nets; 5 one direct current electric fields; 6 one positive and negative electrode nets form alternating-electric field over the ground; 7 one wet oils; 8 one crude oil are deviate from current direction; 9 one low wet oils advance electric field; 10 1 cleaned crude oils; 11 1 oily water terminations; 12 1 water bodys; 13 1 deviate from current direction.High-voltage rectifier 2 is made up of two diodes, and an end of two diodes is done the end that reverse connection is connected to step-up transformer 1, and the other end of two diodes is received positive electricity polar net 3 and negative electricity polar net 4 respectively.This power supply is supplied with the single-phase half-wave DC of electrical dehydrator.Because electric field 5 directions are constant all the time between positive and negative two arrays of electrodes net, so be called DC electric field; And electric field 6 directions that form respectively between a positive and negative two arrays of electrodes net and the oily water termination are opposite, are equivalent to an alternating electric field.So the electric field of claiming this form is an AC and DC two-fold electric field.Wet oil 7 self-electrodes side off the net 6 places get into, and at first stand alternating-electric field and handle, and deviate from after the portion water 8, and low wet oil 9 gets into electric field 5, through further handling after crude oil 10 effusion electric desalting and dewatering devices.The vertical electrical polar net industry spot electrode network distribution scheme of crude oil electro-desalting dehydrator internal electrical polar net shown in Fig. 1 (e), wherein, 17 1 power line directions; Globule coalescence direction in 18 1 roily oils.Promptly " positive electricity polar net-negative electricity polar net-positive electricity polar net-negative electricity polar net-...-positive electricity polar net-negative electricity polar net " the electrode network distribution scheme of no ground-electrode net, in like manner, also can provide horizontal electrode net distribution scheme.
The applicant discovers above-mentioned phenomenon:
The first, for the crude oil emulsion that does not have capacitive, its electric field distribution shown in Fig. 1 (b), wherein, 14 1 positive and negative electrode net voltage peaks; 15 1 positive and negative electrode net voltage downcurve line directions.Voltage between positive electricity polar net, negative electricity polar net and the ground rise and downcurve as Fig. 1 (b) 14 and 15 shown in; Axis of abscissa is represented ground potential, and positive half cycle curve is represented positive electricity polar net voltage to ground, and the negative half period curve is represented negative electricity polar net voltage to ground; There is not voltage between positive electricity polar net and the negative electricity polar net; Therefore, for the electrode network of Fig. 1 (e) arranged distribution, electric field 5 can not be set up between the positive and negative electrode net.Here it is, and AC and DC Double Electric crude oil electro-desalting dehydrator can not play the reason of electrodesalting and electrodehydrating effect for the high crude oil of water cut.
The second, for crude oil emulsion with capacitive, the voltage curve between positive electricity polar net, negative electricity polar net and the ground shown in Fig. 1 (c), wherein, 16 1 positive and negative electrode net voltages time-delays downcurve.Axis of abscissa is represented ground potential, and positive half cycle curve 14 is represented positive electricity polar net voltage to ground with curve 16, and negative half period curve 14 is represented negative electricity polar net voltage to ground with curve 16.Dash area shown in Fig. 1 (d) is represented the voltage curve between positive electricity polar net and the negative electricity polar net.For the positive electricity polar net, the numerical values recited of voltage is divided two stages, and the fs, the numerical value of voltage depends on the capacitance discharges situation, and electric capacity is big more, and voltage can be high more; Subordinate phase, electric capacity get into negative charging, and the numerical value of voltage depends on the position strength of electric field of electrode network, and volts DS is passive and passive.Negative electricity polar net curve has and the identical character of positive electricity polar net curve.
The 3rd, the electric field controllability is poor between the electrode network.For the electrode network arranged distribution shown in Fig. 1 (e) and Fig. 1 (f); Because the two arrays of electrodes net does not form the loop; Volts DS on every group of electrode only is 45% of a voltage of alternating current; The strength of electric field that DC electric field between positive electricity polar net and the negative electricity polar net does not reach desalting and dewatering a little less than does not even work very, and what really play the desalting and dewatering effect is alternating-electric field.In order to improve the DC electric field between positive electricity polar net and the negative electricity polar net; Document (Yu Damin; To the superficial view of " two electric field " crude oil electric dewatering, oilfield surface engineering (OSE), 1987; 6 (2): 14-17) propose to use the method that increases electric capacity to improve DC electric field intensity; But, because the DC electric field between positive electricity polar net and the negative electricity polar net is the influence of the locus that electrical capacity and electrode network are between the positive and negative electrode net and is passive passive that the method for this increase electric capacity is very limited.Therefore, the extraordinary dehydrating of crude oil technology of existing Double Electric is difficult to obtain desired effects.
