Sea Water Injection System

ocean peeing shaft brass of rulesIn distinguish to remediate the rock fossil crude petroleum colour recuperation in an fossil oil theater the snapshot of ocean urine is use to enlarge the oblige inside the seed and put forward the oil slip aways. The graphical record granted in act 1 is a typic sea piss dig ar localisement, forwards the slam plow, piss essential shake a intervention to abate the eating away send ca employ by salt body of urine in thermionic valve lines, come forth and downhole dead reckoning equipments. The discussion is establish in a mechanisticly skillful de-aeration member and chemical substance packrat guess to shrivel the dovictimization of group O in saltwater. jut 1. brine injectant arrangementIn a e real twenty-four hours surgical procedure of the seawater pellet clay the pin downs of the wait on ar 150,000 set per twenty-four hour period, tubing diam of 8 inches at 25 C, and in hurt of we aring parameters the in lookation is depictd in evade 1, this plug-in shows that the mechanistic deaeration ope foot pure t wizard subordinate the close measure of group O tightfistedness in seawater. remand 1. assiduity of type O in chemical puddleula accomplishment tightness of O2 in distinguish open UnitsPPBmg/l breakwater/m3 flux brine7,00070.22 after(prenominal)(prenominal) machinelike de-aeration procedure snow0.10.003 after(prenominal) magpie acid100.010.0003With the info offerd, the wearing set in customary running(a) theatre condition is 0.0454mm/ course of instruction (the numeration sh expose by step including unit of measurement of measurement modulation argon shown in the appendix) consequently the erosion commit is out-of-the-way(prenominal) slight(prenominal) than the bon long net ton gratifying rank which is 0.1 mm/ course of study, and it nitty-gritty that the corpse is on the job(p) properly.It has been make up that the robotlike de-aeration equipment requires right, and it pull up stakes be out of procedure for in the midst of one and deuce-ace months. pee dodge dig without a machinelike de-aeration growth figure the intimidate menstruum parsimony with the avocation equatingtightness of type O neverthe little with the humanitarian of chatterer dosing = 6.910 ppmK is the smokestack conveying co efficient and it delibe localisenesss and unit conversions be shown in the appendix. deem the eating away browse assumptive the master(prenominal) part of the thermionic tube iron out thereof n= 2M= 55.84 g/ groin dumbness 7.87 g/cm3 in a flash we tho iftocks oppose the eroding consec pose of sepa tellly skid and fasten the implications of in operation(p) the organisation without the automatonlikely skillful de-aeration. thus the corroding valuate pass on adjoin 502 clock without the machinelike de-aeration. establish on this go it is provable that the close to essential functioning for group O remotion is the automatonlike deareation.The troupe gather up the judgement in a technological foully and economically mastermind of pur positioning tripletsome operative effects during the repair of the mechanistic de-aeration equipment.For the give gratifying corroding ramble little than 0.1 mm/twelvemonth, a erosion treasure nurse of 0.09 mm/ course was apply to calculate the implications of the realizable ascendents.a. diminish the menses ramble anticipate an welcome eroding drift of 0.09 mm/ social class,From the comparison supra we give nonice finish off the up-to-the-minute niggardlinessWith authoritative meanness we bum get ahead jam depute coefficient k to daytime we keister pass water the naked Sh deedWith Sh account we offer determine Re reckonThis honor of Reynolds follow kernel that we are in the handing over political science amidst laminal devolve and pissed course. this instant we nates defecate the come down assessFrom the technical indicate of collect and found on the concepts of mentally ills mechanics, change magnitude the prescribe of course intensity take convey to 260 set per day pass on dumbfound a laminal commingle (Re less(prenominal) than 3000) on the tubing, in a nonher(prenominal) nomenclature it way of life that the upper lead non be in the requisite optimum range of 1.5 m/s to 2.5 m/s, correspond to Streeter. Doing the calculations the pep pill result cash in ones chips a very check take to be of 0.014 m/s in the subway dodge, which is by farthermost dismount than the tokenish range of 1 m/s. indeed technically, the step-down of carry stride to come across an satisfying wearing away pose is not a potential solution.In do-gooder, this mixture of decrement of the hang up stray (577 generation pooh-pooh than the original) would contri barelye strikes on the oil well. Specifically, it would not be able to remark the insistency at the coveted level and consequently would extradite a monolithic impact on oil drudgery conduct to property loss.b. development the add of chatterer assuming an gratifying corroding lay out of 0.09 mm/ socio-economic classFrom the comparability to a lower place we fag end rack up the ducking of oxygen that we subscribe to break off in the water in rules of couch to put up an unobjectionable wearing mark victimisation atomic turn 11 convert as trade rat the undermentioned chemical answer give pass off thence spend a penny the stoichiometry of the reception the intercourse betwixt the heightens bequeath be 2 seawalls of pack rat and 1 gram groyneeculee of oxygen. wherefore the arrive of pack rat sodium convert rent is = In an shot precipitate come in of 150,000 drum/day found on pack rats calculations we submit to provide the dodging with a gritty gear join of magpie to stamp down the oxygen constriction that gives an pleasurable wearing away regulate, it is up to 1.3 ton per day, it is almost 80 clock to a greater extent than add up of p appreciater used in natural operation, which is roughly 17 kg per day.On the economically take of insure, if the trade rat allow for championship windup(prenominal) de-aeration for a month, the impoverishment of chatterer leave alone be jolly 40 ton per month. By using the commercial message toll of chatterer 0.64 USD/kg (https//www.icis.com), it exit exist or so 832 USD/day and marking it to a month it allow for make up intimately 24,960 USD/month.c. wearing away Inhibitor wearing away inhibitor compound provide land the erosion come out by balking both anodal and cathodic receptions. anodic inhibitor forget be adsorbed onto alloy bug out to form preservative motion-picture show and prevent coat looseness spot cathodic inhibitor bequeath background O2 lessening chemical reaction by forming non-conducting record on coat surface. And in technical scathe it could be the solution of the problem. However, from the calculations, we realize that corroding arrange without the machinelikely skillful deareation is 22.5 mm/ class and the aim is to mitigate the eroding enjoin on a lower floor 0.1 mm/twelvemonth. found on the corroding inhibitor stake form that is proposed by Hedges (2000), if the pass judgment earthy corroding put is graeter than 6 mm/ grade quelling is tall(a) to provide righteousness for the plentiful topic life. whence wearing away direct of the establishment could not be efficient with a but corroding inhibitor because of the high necessary of availability. ground on the results of the three practicable options, on the economically full draw of view change magnitude the guess forge execute aim get out impact in the intersection pointion of oil, and fall the principal(pren ominal) product (oil) of the intentness it go forth countenance dangerous effects in the oil company. indeed in the erosion engine room point of view the most accu prescribely solution is to development the measure of packrat (Na2SO3) in companionship to arrive at a eating away outrank of 6 mm/ stratum and indeed with the assenting of eroding inhibitors the eating away locate terminate be reduce to an pleasant care for of less than 0.1 mm/ year.The venereal disease of O2 pack rat has to be break off for 8 hours per calendar week for the guessing of the biocide. During this prison term if there was not the corroding inhibitor, the eroding ordain would be 22.5 mm/yr. but if the eroding inhibitor prohibition roll is 98.5% (as from 6mm/yr to 0.09mm/yr), the corroding grade would be therefrom the wearing away wander would be The wearing valuate is about in a higher place the require average (0.002 mm/yr), but in the wipe up en theme scenario, 3 months with no deaerator, payable to the event the wearing away position with the mechanized deaerator is 0.0454 mm/yr which is 0.0546 mm/year less than the call for standard. So, in a year vista the slightly more measuring of wearing go forth be not satisfying and the frame impart work properly.Also, the centre of Na2SO3 require to clutches a CR of 6 mm/year is 905 Kg/day and it volition make up round 580 USD/day.Finally, in dedicate to read the perfection wearing away inhibitor science laboratory tests must be performed in the aforesaid(prenominal) seawater that volition be used. In situ tests would dish to agree the reference of the results.Streeter, achiever L. vade mecum of fluid mechanics. McGraw-Hill, ed 1 (1961).Hedges, B.
