Abstract: This paper is about the Design of detailed process involved in the Automation of the terminals in the oil and gas industry. Paper discusses about different levels included in the Terminal Automation System , the different equipment involved and the Design of them.

2 The oil and gas industry is the one of the most Control room includes the equipment such as important sectors of Indian economy. We have servers, mod buses, switches, PCs, RTUs etc. This been using oil and gas for the past thousands of will receives the field signals through RS 232/485. years. Oil is mainly found in natural reservoirs or cables. All the systems in control room will be may be collected from seepage or tar ponds. connected in the LAN network. SCADA is used to control all the processes from the control room Since both oil and gas are highly inflammable, it is remotely. very risky to deal with it. So many hazardous events have occurred due to carelessness and some The control signal from SCADA will energise the System made mistakes. Terminals are the place PLC and it will act.

3 Two types of PLC are used in from where we dispatch the refined products of the Terminal Automation . Process PLC and Safety PLC. refineries. Most of the products are highly Process PLC controls the pumps, barrier gates, inflammable and they have high cost also. So we DBBVs, etc. Safety PLC is used for safety need a highly safe, risk free and obviously purposes like ESDs. profitable environment in this field .This scenario brings out the relevance of automating this The process of Terminal Automation starts when industry. The oil and gas market is the fastest truck entries in the Terminal and it will end when growing industrial market for process Automation the truck leaves the Terminal after filling the fuel. In today. Here we can discuss about the Automation of between this there are a lot of process are occurring terminals in the oil refineries.

4 Like SAP TAS interfacing , fan generation, entering licensed area, batch controller working , loading , Even though terminals are the last part of the truck cancellation, bypassing, truck aborting etc. refinery, they are the most unavoidable part of The success of Terminal Automation System many industries across the world, they needs completely depends upon these different processes Terminal Automation System which performs in in it. faster and efficient way. It includes starting from the pipes which carries the oil, tanks used for TAS has mainly 8 subsystems. They are storage, trucks and wagon used for transporting the oil, the bays from where the trucks are filled etc. I. SAP-TAS INTERFACE. We can include the whole processes in three headings. SAP-TAS interface is developed to automate the data transfer between client and server TAS.

5 Field and field equipment System . It consists of built in control and Control room and SCADA executable scripts for its proper functioning. PLC. II. GANTRY Automation System . Field and field equipment include all the pipe lines, [2]The gantry Automation System is the heart of the tanks, trucks, wagons, batch controllers, card Terminal Automation System . It is mainly about the readers, sensors , radar gauges, RTDs, air transfer and control of the products. It includes the eliminators, strainers, valves etc. batch controller unit, Proximity Card reader, Overspill Prevention Device, Static charge 111. International Journal of Research in Advent Technology, , , April 2016. E-ISSN: 2321-9637. Available online at grounding device, Loading Arm, Loading Arm VIII. ACCESS CONTROL SUBSYSTEMS.

6 Position detection device cum arm interlock, Digital Control Valve, Strainer cum Air eliminator, This subsystem is responsible for controlling Flow meter, Pulse transmitter, and Temperature vehicle entry and exit at the facility. The various and Pressure transducers. components include barrier gates, card readers, traffic lights, vehicle sensors, a security station and III. ADDITIVE INJENCTION AND related accessories. BLENDING System . BATCH CONTROLLER UNIT. [2]The diversified demand of fuels in today's era is driven by various factors which include the base [1][2]The proper working of TAS is mainly based product modification. It includes accurate blend of on the working of Batch controller unit. A batch two or more products enhancing the capability of controller is an intelligent device designed for base product by injection of special additive, to loading operation in terminals of petroleum mark the product with injection of the marker.

7 The refineries and oil marketing terminals. This will additive injection and blending solutions offered by control and manage the transferring of different us helps in operation flexibility and enables to load petrochemical products onto road tankers and rail multiple products from same loading arm and cars. Precisely batch controller is an intelligent reduce dependency on multiple storage tanks. device used to deliver the set amount of liquid along with control flow, BC monitors digital as IV. TANK FARM MANAGEMENT System well as analog parameters essential for continuing (TFMS) batch delivery process. There are different make of batch controllers are available in the industry like [2]This subsystem manages the product stored in SMARTLOAD (GE), CONTREC. large tank and constantly monitors the product (HONEYWELL) etc.

8 The main functions of batch level in each tank. It also monitors the product level controller are Batch delivery, Blending, Additive in each tank and other important information like injection, Meter Proving, Transaction Storage /. density and temperature. Components of TFMS User Defined Transaction Ticket, LPG / Pressure includes tank gauges, temperature sensors, tank Control, Calibration Monitoring. slide indicators, water bottom sensors , communication interface units and tank farm CARD READER UNIT. software. V. TANK TRUCK ENTRY SCHEME (TTES) [2]The card reader is designed to restrict the access control of unauthorized person / vehicle is This subsystem manages the FAN (Filling hazardous and non hazardous harsh area. This is Advisory Note) generation process. When the certified to ex ia, IIC, T6, the Sentry is intrinsically packet data came to server from client SAP it will safe and therefore suitable for use in most generate FAN.

9 Hazardous of area, including those certified as zone 0, where there is a constant risk of an explosive VI. TANK TRUCK REPORTING System atmosphere. It can be configured to read a range of (TTRS) different card technologies. When a truck enters the parking lot, the RFID card The Sentry comprises a weatherproof box housing reader of the parking lot will read the barcode of the electronics requires to format the card data for the truck. According to that the details of the truck transmission to a host computer and a card reader will load to our TAS from database. Here we have head. One of several card reader head options may two philosophies - truck pending and truck waiting. be fitted to this box. VII. CONTROL ROOM SUBSYSTEM SCADA System . This subsystem is used to control and monitor the [1][3]It helps to control the entire operation of the operation of entire Terminal Automation System in depot starting from truck arrival till its exit from remote mode.

10 It includes redundant Load Rack the depot. It also integrates the storage tanks, Computers (LRC), Operator Interface Computer valves, flow meters, and all the parameters of them (OIC), printers, networking components, PLC, to the System . It enable the operator to control the UPS, panels, consoles and related systems. The depot with the help of various modules like SCADA will be installed in the LRCs. Configuration module, Operation module, FAN. module, Gantry module, System status module. It 112. International Journal of Research in Advent Technology, , , April 2016. E-ISSN: 2321-9637. Available online at provides clean overview of various operations at Close in the event of ESD (anywhere in depot. PLC is also integrated with SCADA System . the location) activation DBBV shall close under ESD condition TANKS and from LPBS.
