What is the relation between API gravity and specific gravity?

API gravity is inversally proportional to the specific gravity. so if the value of spcific gravity for some material is higher , it means that the API gravity of the same material will be lower.


Why do you treat lower API gravity crude to meet product specification?

Lower API crude requires treatment in high temperature and longer retention time to meet proper oil production specification Note - lower API (light crude) is free flowing while higher API (heavy crude) does not flow easily.


Api 24.8 converts to how many bbls per metric ton?

6.948 {| |- | Gravity to MT density (kg/liter) = 141.5/api+131.5 Converstion factor = 1000/(density * 158.985L) 158.985 L = 1 barrel Calculator API 24.8 Converstion: 6.948 |}


What is the lightest oil?

No. Liquid ether at 72.72 kg/m3 is much lighter than crude oil at 790 (or so) kg/m3.


What is the weight of bitumen per liter?

It varies. It is dependent upon it's exact chemical makeup, which varies from location to location. The American Petroleum Institute has developed a measurement system (called API gravity) of various oils and tars which measures the weight at 60 degrees fahrenheit (15C) and compares it to that of water. An API gravity of 10 is equal in weight or density to water. Lower gravity is heavier and higher gravity is lighter. Bitumen, being a heavy tar could have an API gravity anywhere from 8 to 11, meaning it may or may not float in water. this also means that its weight per liter also falls between 1.14 Kg and 0.99 Kg.

Api gravity to pounds per gallon?

The Formula for convert API gravity to pounds per gallon is: Pounds per Gallon = (141.5/(API Gavity+131.5))*8.3378 <--[which is weight of fresh water] API of 10 is same as weight of water. API >10 will float

Which are light liquids?

By using API gravity value of a liquid we can check that how a liquid is lighter or haavior one.First we should know about API gravity.The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a liquid is compared to water. If its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks. API gravity is thus an inverse measure of the relative density of a petroleum liquid and the density of water, but it is used to compare the relative densities of petroleum liquids. For example, if one petroleum liquid floats on another and is therefore less dense, it has a greater API gravity. Although mathematically, API gravity has no units (see the formula below), it is nevertheless referred to as being in "degrees". API gravity is graduated in degrees on a hydrometer instrument. The API scale was designed so that most values would fall between 10 and 70 API gravity degrees.M.Hassan Haq NawazB.sc. Chemical Engg,University Of Gujrat,Pakistan

What are crude densities?

What is crude densities? Crude densities are measured in api gravity. Api gravity is found by placing a hydrometer in a cylinder of crude at 60 degrees Fahrenheit and reading the depth the hydrometer has sunk into the crude.


Api gravity of heavy crude?

crude weight starts at 10 being the highest!


What is specific gravity of crude oil?

Specific gravity of crude oil is how light or heavy it is compared to water. If the API gravity is less than 10 it will float in water.

Lower API crude requires treatment in high temperature and longer retention time to meet proper oil production specification Note - lower API (light crude) is free flowing while higher API (heavy crude) does not flow easily.
