水中油检测仪原理及分析方法水中油在线监测仪器专]设计连接油冷却器或冷却循环水，OMD系列为适应较高的水温而专门]进行了改进。
而且测量范围已经根据预期的油的浓度进行了修正。
该仪器依据IMOResolutionMEPC.107(49)标准制造。
仪器出厂配有2个报警点，两点出厂值10ppm，其他数值的设定(20ppm或30ppm)可以在现场随时通过仪器前部面板的按钮进行调整，如果测量值超过报警点，在仪器前部的面板上发出明显的信号,同时通过继电器传出。
另外配有0(4)-20mA(等同于0-100ppm测量值)的测量信号输出，可以连接外部选定的记录器。
在线水中油分析仪测试原理:采用几个光学传感器,侦测通过水流样品中油滴对光的折射和反射光的强度，然后传感器的信号通过微处理系统计算水中油份的含量并形成线性读数输出。
如果一一个报警器(出厂设置10ppm)发出报警，第二报警器将会在超过设置时间后运行。
微处理系统会不间断的检测传感器部件及相关的电子元件,以确保在超过维修时间或极端的条件下测量的准确度。
水体中总含油量检测（水体中石油类/动植物油类含量）是近年来水质监测的新热点，可以覆盖油田、石化、炼油，采油、输油、工业冷却水、循环水、锅炉用水、中水回用等很多领域，实时、快速、准确地检测技术成为新的应用需要。
水中油分析技术常用的分析方法主要集中在：重量法、红外分光光度法、非分散红外法、紫外分光光度法、荧光光度法、色谱法、超声法、浊度法、光散射法，经过多年的应用，其存在的局限性如体积庞大、结构操作复杂、灵敏度低、选择性差、分析速度慢、分析时间长、或为实验室专用、或需要添加吸附剂等都限制了他们的应用领域。
紫外吸收水体总含油量分析仪，以期满足水中油检测更广泛的现场应用需求。
紫外吸收水体总含油量分析仪设计理念依据“国准方法GB/T16488-1996，国家环保总局标准（HJ/T92—2002）《水污染物排放总量监测技术规范》石油类、动植物油监测方法的自动在线监测法为（红外法、荧光法）”，利用矿物油/动植物油类受到紫外光激发会产生可见光波段的荧光特性，在仪器设计上不仅可用于在线监测，也可以实验室应用。
水样的萃取过程用HcL调PH<2,将一定体积（一般500ml）的水样全部倾入分液漏斗中，先用50ml四氯化碳洗涤采样瓶后移入分液漏斗中，摇晃振荡3min。
在摇的过程中要开启活塞排气。
静置分层后，将下层萃取液放入150ml带有磨口瓶塞的锥形瓶内。
并加入5克的无水硫酸钠摇晃数次直到无水硫酸钠没有完全结晶即可取下清液等待测试（总油），震荡20min，若浑浊，用40mlG-1型玻璃砂芯漏斗过滤，即可测试样品。
然后再把剩余的水样放入量筒测量体积等待输入软件测试计算。
如果测试石油类继续往锥形瓶加5克的硅酸镁摇晃数次后过滤等待测试石油类。
（详情参照国家标准）样品测定方法1> 在测定样品前，先打开电脑及测油仪电源开关，预热10-15min，此时可以先取一个比色皿，倒入空白（四氯化碳）后放入比色池中,进入软件界面,选择“空白测试”,重复3次,点击“开始”,让其自动调零,待空白谱图比较重合时,就可以进行样品测定了；如果不重合，点左上方“清屏”，重新点“开始”测试。
直到空白调零谱图重合方可测试样品。
2>在软件界面，选择“样品测试”，把萃取好的样品倒入比色皿，放入比色池，再进入软件右上方界面把溶剂定容体积（萃取过程中四氯化碳用量），水样体积（萃取完成后分液漏斗中剩余水样的体积）输入，再从软件界面从标准曲线方框内选择“标准曲线”；之后再样品名称栏内修改样品名字，点击“开始”,就可以进行测定了。
测定结束后，结果显示在下边的表格中。
（样品横向最后一行 RSD/DL 必须小于0.2或2%.如超出需重测或重新空白调零）。
国家质量技术监督局和国家环境保护总局联合发布了中华人民共和国国家标准“水质、石油类和动植物油的测定——红外光度法”。
从而统一了油类测试的标准问题。
标准中不但明确了油类物质测定时所用的萃取剂是四氯化碳，而且对四氯化碳的质量提出了一定的要求，在红外吸收光谱中，不但考虑了亚甲基CH2基团中C-H键的伸缩振动（波数为2930cm-1），甲基CH3基团中C-H键的伸缩振动（波数为2960cm-1），也考虑了芳香环中C-H键的伸缩振动（波数为3030cm-1）。

INTRODUCTIONThe OCD CW Oil Content Meter has been designed for use as a detector of hydrocarbons in sample streams, up to 99 ppm. It has a specification and performance that meets thecurrent international requirements for cooling water applications as laid down byGermanischer Lloyd.2. IMPORTANT NOTESa) This equipment must be installed and operated in strict accordance withthe instructions contained in this manual. Failure to do so will impair theprotection provided.b) A competent and suitably skilled person must undertake installation andservicing.b) The equipment must be provided with a sound electrical earth connection.d) The unit must be isolated from the electrical supply before anymaintenance of the equipment is attempted.c) All National or local codes of practice or regulations must be observedand, where applicable, are deemed to take precedence over any directiveor information contained in this manual.d) Hazardous voltages are present within the monitor enclosure3. PRINCIPLE OF OPERATIONA set of optical sensors measures a combination of light scattered and absorbed by oildroplets in the sample stream. The sensor signals are then used to calculate a PPM value by a microprocessor. The micro processor also drives a 0-5v, 1-5V, 0 – 20mA, 4 – 20mA dc linearised output, two seven segment displays, six light emitting diodes, two oil alarmrelays (at adjustable 1 – 99 ppm set points) and one fault relay.The microprocessor continuously monitors the condition of the sensor components andassociated electronics to ensure that calibration accuracy is maintained over time andextremes of environmental conditions.In the event of a failure the oil alarm relays and fault relay are set to the alarm state (de-energised) and both alarm status indicators and fault indicator are set to RED. An errorcode is displayed on the two seven segment displays relating to the fault identity.4.

CONSTRUCTION DETAILS (Refer to Fig 5.1)The OCD CW, in common with other versions of the OCD series, is a veryrobust instrument ideally suited to the aggressive environments of marine engine rooms.The measuring cell is a sealed unit set to the right hand side of the enclosure. The inletpipe is situated on the bottom of the cell (8) and the outlet pipe is situated on the top right hand side of the cell (3). A desiccator (7) to eliminate moisture around the outside of theglass tube and a throttle (6) to regulate flow and maintain pressure are also fitted to thecell.The main electronics are all contained within the enclosure on two printed circuit boards.Additionally a small PCB containing transmitters and sensors is contained within themeasuring cell. The display board (2) is mounted to the front cover and provides the PPM display (4) and the six light emitting diodes. The mother board (1) is mounted to the back of the enclosure and contains the power supply, alarm relays, digital to analogue andamplification circuitry.The front of the monitor is fitted with a membrane user interface containing three pushbuttons (9), and windows for the LED displays.Fig 5.1 CW Construction Configuration75ITEM No. DESCRIPTION ITEM No. DESCRIPTION1 MAIN P.C.B.

Autoclean System (where fitted) (refer to Fig 6.1)The Autoclean System adds another level of reliability to the OCD CW through theautomation of the cell cleaning process. The assembly is designed to clean the cell tube every 5 – 60 minutes (user selectable see section 9 sub section 7) to reduce the build up of scale and other deposits on the inside of the glass.The OCD CW is mounted onto a stainless steel back plate (4). Two conduits providepassage for wiring between the monitor and the customer terminal enclosure (3). Wiring is also provided to connect the solenoid valve (2) to the terminal enclosure, which in turn is connected to the autoclean control relay (fault relay on stand-alone monitor). The solenoid valve controls the airflow to the autoclean cylinder (1), which drives a wiper up and down to clean the cell tube. The air inlet fitting is 1/8” BSPT and flow should be regulated between 4 and 6 bar.It is important to note that all the existing wiring on the panel is essential to the operation of the autoclean system and that removal of any such connections will impair the operation of the monitor.Fig 6.1 CW Autoclean Construction ConfigurationITEM No.DESCRIPTION1 AUTOCLEAN CYLINDER2 SOLENOID VALVE3 CUSTOMERS TERMINAL ENCLOSURE4 MOUNTING PLATEBelow is shown an expanded view of the customer terminal enclosure. Terminal identities match with those shown in section 8 (Fig 8.1) except for the fault relay which is not available with the autoclean option.Fig 6.2 CW Autoclean Terminal EnclosureAll remaining connections to the OCD CW can be made as shown in the following sections.7. INSTALLATION (Refer to Fig 7.1)See section 2 for important notes . LocationThe OCD CW monitor should be located on or in close proximity to the oily-water separator to minimise response delays. Under no circumstances should the distance between the monitor and the separator exceed 8 metres since this would result in a response time of more than 20 seconds and breach IMO regulations.MountingMount the OCD CW by means of 4 x M4 screws on to a rigid vertical surface and preferably with the display panel of the monitor at eye level.Fig 7.1 Installation GuidelinesCLEAN WATER2 M MIN10 mm PIPING8. WIRING (Refer to Fig 8.1)See Section 2 for important notes concerning wiring.This unit must be connected to the mains supply via a suitably rated and approved fusedisolator unless such fusing/isolation is provided by associated equipment. When fitted the isolator should be close by, readily accessible and marked as to function.Cable entries can accept cables from 6 to 12mm² diameters. The terminal block will accept cable cores of up to 4mm² and cables carrying hazardous voltages must be at least0.75mm² csa. When terminating mains cabling at monitor and electrical source, the earthconductor must be made longer than the live and neutral conductors.To select between 230V and 115V supply a link (or two in the case of 115 V), is attachedon JP1 and JP2 in the relative formations shown in fig 8.1. The link must be electricallyinsulated and at least 0.50mm² csa.Note to make connections to J11, J12, JP1 and JP2 terminals may be pulled out of PCBconnections via tags or links provided.Precise wiring details will vary dependent upon the control system to be employed but the most frequently used systems employ Alarm relay 1 for control purposes and Alarm relay 2 for alarm annunciation only.Connections to the cables should be made as shown in Fig 8.1Fig 8.1 Terminal Connections OCD CWALARM 2 MAINS IN9. COMMISSIONINGSee section 2 for important notes.Fig 9.1 User Interface guidelineOn completion of the installation, wiring and piping carry out the following checks: -1) Electrical•Check that the power supply voltage on cables 1 and 2 are within limits.•Check to confirm that a good connection to earth has been made.2) Piping•Check all piping connections for leaks and rectify as appropriate. Functional Tests (refer to Fig 9.1)•Turn the supply voltage to the Monitor on; the display (1) should read FC (Factory Calibration) for 3 Seconds. (*Note this will only change to CC if a full-scale calibration is performed outside factory conditions).•The monitor will then run through a self-diagnostic and initialisation routine.During this time the display will count down from 40 to 0 and back up to 40again. Alarm LED’s will extinguish + illuminate at alarm set points.•Run oil free water through the instrument for a short period to purge the system of air and dirt.•Adjust the Throttle screw (Fig 5.1 – 6) in the cell cap so that the flow rate through the cell is between 0.5 and 2 litres/min. NB. The flow rate should bechecked on both the clean water supply and the separator sample supply. If theclean water supply is obtained from a high pressure source, it may be necessaryto restrict this at a point up-stream of the clean water/sample 3-way selectorvalve.•Switch the clean water supply to the instrument and after 2 minutes set zero in accordance with the Operating Instructions (see sect 9.5).•Set-up the monitor to give a 0 – 5V analogue output and connect a voltmeter across + V out and – V out(see sect 9.6). The reading should not vary bymore than 0.25v above zero (equivalent to + 1.5ppm). If the reading varies by agreater amount, air entrapment is almost certainly present and changes to thesample piping or sampling take-off point may be necessary.3) Setting Alarm points (refer to Fig 9.1)•Alarm 1 and alarm 2 are both factory set to 15 PPM. To adjust these points the following procedure should be followed.•To adjust alarm 1 set pointPress & release the DOWN or UP KEY (10 or 9) repeatedly until the PPM LED(3) and the ALARM 1 ADJUST LED (6) are both on, the alarm 1 PPM set point isnow displayed.Press & release the SET/ZERO KEY (8).Adjust the PPM value by pressing the UP or DOWN KEY (10 or 9) until thedesired value is displayed.

OPERATOR MAINTENANCE (Refer to Fig. 5.1)See section 2 for important notes.AT WEEKLY intervals: -a)Check the zero with oil free water flowing through the instrument and reset ifnecessary (see section 9 sub section 5).b)Flush the cell with oil free water.c)Isolate the instrument from both sample and oil free water supply.d)Unscrew and remove the cell cap (5).e)Insert a bottle brush into the cell using an upwards and downwards motionthrough the entire length of the cell several times.f)Remove the bottlebrush and replace the cap (5).g)Re-connect the oil free water supply and allow this to flow through the instrument fora few minutes.h)Re-check the zero calibration againi)Re-connect the instrument to the separator sampling pointAT MONTHLY intervals: -a) Check the colour of the DESICCATOR window (7) to ensure it is blue, indicatingcorrect moisture content of cell. Replace Desiccator if colour is either PINK orWHITE.b) Install new Desiccator by unscrewing the old Desiccator unit (7) and inserting a newone. DO NOT OVERTIGHTEN DESICATOR – Finger tight is sufficient. Ensure theO ring seats properly against the cell housing.AT YEARLY intervals (units with autoclean / manual clean only): -At yearly intervals (or where necessary) the wiper ring on the autoclean / manualclean assembly (where fitted) should be replaced.
