Oil Test Centrifuge
Oil Test Centrifuge TT-1796
Oil Test Centrifuge TT-1796 adheres to several ASTM standards, including ASTM D1290, ASTM D1796, ASTM D2709, ASTM D4007, ASTM D91, and ASTM D96. This Oil Test Centrifuge is fully programmable, allowing automatic configuration to specified oil test parameters.
It features a four-place swing-out rotor and universal bucket assembly that accommodates low-cost adaptors and cushions suitable for borosilicate glass centrifuge tubes specified for oil testing. This centrifuge facilitates the laboratory determination of water and sediment in crude oils using the centrifuge procedure.
However, this centrifuge's accuracy in determining water and sediment in crude oils may not be entirely satisfactory. The amount of water detected is often lower than the actual water content. For highly accurate results, revised procedures for water determination by distillation are recommended.
The water and sediment content of crude oil is significant as it can lead to equipment corrosion and processing issues. Accurate determination of water and sediment content is essential for precisely measuring net volumes of actual oil in sales, taxation, exchanges, and custody transfers. It is not expected that this test method, designed for dedicated laboratory facilities, will be utilized in field test rooms or sample rooms due to safety concerns regarding proper ventilation and handling.
The primary application of the Oil Test Centrifuge TT-1796 is to determine the volume of water and sediment in crude oils and fuel oils, a test commonly known as Basic Sediment and Water (BS&W). In compliance with standards like ASTM D4007 and ASTM D1796, the centrifuge separates the denser water and solid sediments from the oil. This measurement is critically important for assessing the quality and purity of the oil, as excess water and sediment can cause corrosion and processing problems.
Key Industries
- Oil and Gas Production (Upstream): Producers use this test at production sites to measure the quality of crude oil being extracted from the well. This data is essential for initial quality assessment and for verifying the effectiveness of separation equipment before the oil enters a pipeline.
- Pipeline and Transportation (Midstream): This test is fundamental at custody transfer points—where ownership of the oil changes hands (e.g., from a production facility to a pipeline, or from a pipeline to a storage terminal). Accurate BS&W measurement is required to calculate the net volume of pure oil being bought and sold.
- Petroleum Refining (Downstream): Refineries are the primary buyers of crude oil and must test incoming shipments for BS&W. High levels of water can cause significant corrosion and operational upsets in distillation units, while sediment can foul heat exchangers and other critical equipment.
- The machine features computer control, a touch panel, LCD display, electronic locks, and speed PWM control method. It can store 12 programs, adjust to 19 levels of acceleration and deceleration.
- Thanks to its unique shock absorber, the machine offers excellent anti-vibration effects.
- Speed control utilizes the PID method, offering high precision with customizable acceleration and deceleration times. The brushless motor ensures quiet operation, meeting laboratory requirements without the need for carbon brush replacement, thereby minimizing dust pollution.
- It automatically calculates RCF values and includes a point start function for short-term centrifugation.
- The electronic locks provide security protection; if the door is not properly closed, the centrifuge will not operate.
