The purpose of the oil processing unit is to provide free removal of water and coalescence of entrained water particles to enable the oil to meet pipeline specifications for the area where the unit is recommended and installed. Hetaer treatment device uses the method of heating, chemical action, electric coalescence and sedimentation to deemulsify oil. All heaters use the law of gravity to separate lighter components from heavier ones; gas is the lightest, then oil and then water. Say no to plagiarism.

Bath heaters are used to preheat the emulsion to facilitate mixing and starting the deemulsifying agent. The heated liquid is treated in the heater-treater to reduce the water content. The crude oil with traces of water is sent to the Mehsana CTF plant for further processing to meet refinery specifications and the effluents with traces of oil are sent to the ETP where the remaining oil is removed and the water is pumped back into the earth to fill the space thus created. The heater consists of four parts to carry out the demulsification process: Please note: this is just a sample. Get a custom paper from our expert writers now. Get a Custom Essay Inlet Degassing Section: The produced fluid enters the processing unit above the fire tubes in the inlet degassing section. Free gas is liberated from the flow stream and is equalized through the entire degassing and heating areas of the heater-treater. The degassing section is separated from the heating section by diaphragms. The fluid travels downward from the degassing area and enters the heating section. Heating section: the heater consists of 2 smoke pipes connected to the burners. These smoke tubes must be immersed in the liquid when the burners are operating to avoid damage to the smoke tubes due to excessive heating. This is guaranteed by the microfloat mounted above the smoke pipes. The microfloat through an ON-OFF switch interrupts the gas supply to the burners every time the liquid level drops below the smoke pipes and activates the gas supply when the liquid level rises above the smoke pipes. The desired temperature is maintained in the heater via an automatic temperature controller. Mechanical section: The clean effluent water discharge valve controller float is mounted in this chamber. This float activates the drain control valve whenever the liquid exceeds the set level. The gas pressure in the inlet and heating sections of the vessel is used to move the fluid from the mechanical section to the coalescing section. Coalescence section (electrical section): The electric heater uses high voltage potential on the electrodes for coalescing of droplets. water in the final phase. The liquid enters this chamber through a distributor tube. When the emulsion passes through the electric field, the water droplets in the emulsion become electrically charged and rapidly move and collide with each other. As they collide, the droplets grow in size, forming larger droplets, until they become large enough to settle. In this room there are two grills connected to a.
