Oil processing facilities (Light & Heavy) b) Water processing facilities c) Gas processing facilities a) Oil processing facilities (Light & Heehaw): 0 Heavy oil processing facilities: CAP received heavy oil from Full field (heavy single wells and heavy Smog’s) and from OFF (Mega, FEN and Key’). To process the heavy oil, it must be gone through many main steps (Vessels) before it will be ready to be pumped to P. S #1 or whether exporting.
The main vessels are: * Exchanger * First stage sedimentation tank * Second stage sedimentation tank Surge tank * Shipping tank 0 Light oil processing facilities: CAP received light oil from Full Field (light Smog’s and light single wells) and from OFF Oak and Key). As same as heavy oil, light oil passes through many main steps (vessel) to be processed and then make it ready for exporting or pumping to P. S #1 . Light oil main vessels are: * Production separator * Electrostatic separator b) Water processing facilities : All separated water either from heavy crude or light crude passes directly to the produced water tank. ) Gas processing facilities : Gas usually separated in production separator or it comes directly to CAP by single wells. Surge Tank: It is the connection between sedimentation tanks and shipping tanks. Use to provide stable level for transfer pump. Skimmed Tank: Use mainly to reprocess the separated oil in produced water tank. Shipping Tank: It is the storage tank where the oil store before it pumps to P. S #1 or BE. 2 Produced water tank: Use to collect all separated water and use it in injection or pass it to evaporation ponds. 2. Heating facilities : Heating facilities is one of the most important facilities in CAP.
They are using to increase the temperature of crude to facilitate moving and separation of water. Heating facilities include these three main vessels: * Make up tank & Expansion tank (thermal oil material) * Exchangers * Heaters Thermal oil play vital row to heat the crude. Heaters heat this material and then pass it to exchangers where the crude heated. The chart in next slide shows this loop of heating the crude. 3. Chemical Injection : Chemical injection helps the sedimentation and separation. Three types of chemical injected to the crude in different vessels depends mostly on the type of rude.
These types of chemical are: * Dehumidifiers *Reversed Dehumidifiers * Defamer Defamer uses to remove the foam from crude and avoid the over flow. It injected in outlet of sand trap. Dehumidifiers uses with both types of crude (light and heavy). It mainly uses to separate water from oil. For light oil, it injects before the inlet of separator. For the heavy crude, it injects in outlet of sand trap. Reversed dehumidifiers uses to separate oil from water. It injects in inlet to produced water tank. Other facilities : l. Test skid: It uses with heavy crude to test the daily production off well.
II. Test separator: It as same as test skid but this vessel for the light crude. It tests the fluid off well. Ill. Pumps: certain types of pumps use inside CAP. Type of pump depends on Job. These are most types of pump which is used in CAP: 0 Light pump: use to transfer oil from tank 1932 to shipping tanks. 0 Transfer pump: use to transfer oil from surge tank to shipping tank. 0 Circulation pump: use in blending to control the viscosity of oil going to AS #1 0 Feed pump: use transfer oil from shipping tank to P. S #1 or BE 2. IV. Meter skid: use to measure the flow rate to P. S #1 .
