In the absorption stabilization system, the key to improving the C3 recovery rate is to reduce the amount of C3 in the dry gas. Why?
The key lies in absorption and analysis; with good absorption efficiency, the control of C3 in the dry gas is easier
The initial boiling point of gasoline is ≥30, and the C3 content is relatively low; to increase the yield of C3, it can only be achieved from the dry gas
I have previously been involved in simulating and adjusting absorption stabilization systems; to reduce the C3 content in dry gas, the key is, first, to control the initial boiling point of the stabilized gasoline, and second, to ensure that the flow rate of the absorption oil is sufficient.
The C3 components in dry gas are mainly propane and propylene, and propylene serves as a raw material for polypropylene; therefore, a significant loss of C3 means a significant loss of propylene, which is currently a highly valuable chemical intermediate.
The higher the C3 content in the dry gas, the less you have absorbed
A high level of carbon 3 in the dry gas indicates that some carbon 3 has entered the dry gas system; gasoline separated in the stabilizer generally does not contain carbon 3
