Perau said:it's to my understanding that API n CPI uses the same theory to remove oil from water.
but what are the key differences that makes CPI much more expensive or that make API cheaper?
API and CPI are both methods used in the oil and gas industry to separate oil from water. API, or American Petroleum Institute, is a measurement of the specific gravity of oil, while CPI, or Coalescing Plate Interceptor, is a type of physical separation technology.
Both API and CPI have their own advantages and disadvantages. API is efficient in separating oil from water with high specific gravities, while CPI is better at removing smaller oil droplets. The effectiveness of each method depends on the specific characteristics of the oil and water mixture.
API is typically less expensive to install and maintain compared to CPI. However, CPI may be more cost-effective in the long run due to its higher efficiency in separating oil from water, resulting in lower operating costs.
Both API and CPI can be considered environmentally friendly as they help in the separation of oil and water, reducing the amount of pollutants released into the environment. However, CPI may have a slight advantage as it can effectively remove smaller oil droplets, resulting in cleaner water.
Yes, there are regulations and guidelines set by environmental agencies and industry organizations for the use of API and CPI in oil/water separation. These regulations ensure that the methods are used safely and effectively, without causing harm to the environment.
