![]() ![]() The main purpose of the sensors is to measure the temperature inside the tank and also whether the liquid inside the main blender tank is in the lower level or in the higher level. The stirrer is connected to a motor in such a way that it can be able to rotate in a constant speed for proper mixing of the blend mixture. Tanks with stirrers: – These are the main tanks in which the Input liquids from their storage tanks are A stirrer with motor is mounted at the opening of Blender, consequently inserted into the mixture for mixing.īLOCK DIAGRAM EXPLANATION – The various parts are The fluids which are controlled by SOV valves are Input Feeds, Inner Jacket Fluid, and Blend Mixture. Flow of various fluids is controlled by the use of solenoid valves (SOV) at strategic positions. A heating element is fitted in between the jackets. Temperature Control is exercised by the use of PID along with Thermocouple. parameters are subjected to control in this Blender. The Blender 1 which is made of steel has dual-jacket configuration. Temperature, Level and Flow are the respective parameters controlled in these reactors. ![]() One blender is made of steel, while the other one is made of plastic. There are 3 input feeds arising from separate input tanks. The tank reactors are fitted with stirrers, making there function as that of a Blender. From the storage tanks, samples might be tested for marketing and export of the Motor Spirit.ģ.2Continuous Stirred Tank Reactor Based Blender Control – The prototype is fabricated on the basis of its relational construction detail with MS BLENDING Plant from OM/S unit. The Blending is initiated in this part and the blend mixture is extracted and sent to several storage tanks. All the components are mixed in the blenders positioned at the end of all the inlet pipes. The pipes are fitted with desired control valves and specific positions to regulate the flow of the The pipes extend from the storage tanks of respective blending component. The pipes feed the various input components like Naptha, Reformate to name a few. MS Blending is executed in an intricate system of inlet pipes, blenders and control values. For achieving these standards, petrol companies must ensure the proper blending of MS. a target level of production or a minimum/maximum specification point). The driving force of the blending process comprises any numerical factor that the blender seeks to Maximize (e.g. This is done to achieve the International Standards set for the correct composition and quality of the petrol.Ĭonsequently, this is done to improve the performance and engage more mileage value for the vehicles. The Primary objective of the MS Blending is to produce a high end productįrom its low end counterpart through cracking. Motor Spirit (MS) is commonly known as fuel oil. In general the blending rule is nonlinear it can be regarded as a linear mixing rule adding a nonlinear term. Is an effective method to improve refinery profits. Motor And Blending – Blending is an attractive solution for those refiners who have the ability to blend different crude types to provide a consistent and optimal feedstock to refinery operations. The Block Diagram depicts the arrangement of the following parts: The following is the Block Diagram of OM/S unit. This unit deals with Blending of Motor Spirit (MS) and High Speed Diesel (HSD).Our study of OM/S extends to the MS Blending part. ![]() OIL Movement And Storage – The OIL MOVEMENT & STORAGE OM/S) unit in CPCL is the place where Blending Automation is executed. The scope of this paper is that we can maintain maximum reliability, easily reprogrammed with programming unit, Complete Automation, availability of unlimited number of NO/NC contacts for inputs/outputs, easy installation, power consumption is very low and no special programming skill required by maintenance personnel. A ladder diagram is designed for the same. The second part deals with the implementation of study into fabrication of the prototype of OM/S and execution of simultaneous control of 3 parameters (Temperature, Flow, and Level). ![]() The major advantage of using PLC is that we can easily understand and reprogram and number of input parameters can easily added. An overview of the study includes the study of the present system and attempts towards enhancements of the same using PLC. Bharathi Selva Kumar Radheysham Avnue, Rajakeelpakkam Chennai-73, Tamil NaduĪbstract – The OIL MOVEMENT &STORAGE unit comprises of two Blenders for Euro 2 and Euro3 grades, inputs from 6storage tanks, Naptha sink, storage reservoirs etc. Continuous Stirred Tank Reactor Based Blender Controlled Application using PLC ![]()
