How do you test BS&W?
The BS&W content of crude oil is determined using small centrifuges that are driven by hand or by electric motor. A small measured volume of sample is diluted with solvent and placed in graduated glass containers that then are inserted into the centrifuge and spun for a few minutes at speeds of 2,000 to 4,000 rev/min.
What does BS&W mean in oil and gas?
BS&W (basic sediment and water) Present in most crude oil, BS&W is an emulsion of oil, water and sediment.
What does BS&W stand for?
basic sediment and water
Also known as: basic sediment and water. BS&W refers to the volume of non-hydrocarbon contaminants contained in a cargo of crude oil. Usually, this is made up of dirt (sediment) and water.
What is water and sediments test?
A determination of water and sediment content is required to measure accurately net volumes of actual fuel oil in sales, taxation, exchanges, and custody transfers. 4.2 This test method may not be suitable for products that contain alcohols that are soluble in water.
How do you test water for crude oil?
The centrifuge method for water in crude oil, known as BS & W (Basic Sediment & Water), involves spinning a specified amount of sample for a specified time in a heated centrifuge until all the water and sediment settle in the bottom of the centrifuge tube.
What is the source of water and sediments in crude oil?
Basic sediment and water (BS&W) is a both a technical specification of certain impurities in crude oil and the method for measuring it. When extracted from an oil reservoir, the crude oil will contain some amount of water and suspended solids from the reservoir formation.
Is BS&W same as water cut?
BS&W shows to the customer the amount of crude feedstock which should be accounted into “losses” prior to any processing. A water cut meter measures the water content (cut or percentage) of a specific product as it flow through a pipeline.
How do you measure water content in crude oil?
The water in crude oil is determined by coulometric Karl Fischer titration using a generator electrode with diaphragm. The sample can be directly injected into the titration cell. To help water extraction, xylene is added to the anolyte solution. Xylenes help to dissolve crude oil in the anolyte.
What is sediment content?
Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles.
What is a BS&W Analyzer?
The Analyzers, also referred to as BS&W meters or basic sediment and water meters, are used in many applications including fiscal transfer, production monitoring, and well testing. The product line is based on the innovative sensing technology of oscillator load-pull.
How do you test water for fuel content?
Pour the continents (white powder) into your test vial with fuel. Put on the lid and shake for 10 seconds. Set the vial on the table to allow the mixture to settle and examine the results. 100-200 ppm water will give you pink spots in the white powder.
