AI Technical Summary

⚠Technical Problem

The final boiling point of the stabilized light hydrocarbon products produced during the flash stabilization process does not meet the standard, resulting in the inability to sell light oil products normally and causing loss of profits.

⚗Method used

A flash stabilization process is adopted, including a crude oil buffer tank, a flash stabilization tower module, a primary cooling and separation module for stabilized gas, and a secondary flash stabilization and separation module for light oil. Through primary cooling and separation and secondary flash stabilization and separation, heavy components are separated and the saturated vapor pressure of stabilized light hydrocarbons is controlled to meet relevant specifications.

🎯Benefits of technology

Effective control of heavy component separation ensures that the final boiling point of stable light hydrocarbon products meets the specifications, achieving qualified recovery of stable light hydrocarbons and improving economic efficiency.

Abstract

This invention pertains to the field of oil and gas, disclosing a system and process for recovering qualified stabilized light hydrocarbons in a flash stabilization process. The system includes a crude oil buffer tank, a flash stabilization tower module, a primary cooling and separation module for stabilized gas, and a secondary flash stabilization and separation module for light oil. In the primary cooling and separation module, one pipe of the stabilized gas cooler is connected to the crude oil stabilization tower in the flash stabilization tower module, and another pipe is connected to the stabilized gas separator in the primary cooling and separation module. One pipe of the stabilized gas separator is connected to the light oil separator, and the other is connected to the outlet B of the booster pump in the flash stabilization tower module. The light oil separator in the secondary flash stabilization and separation module has three main pipes: one connected to the stabilized gas separator, one connected to the wastewater treatment system, and the other connected to the light oil storage tank. This invention employs primary cooling separation and secondary flash stabilization separation, controlling the saturated vapor pressure of the stabilized light hydrocarbons below 0.2 MPa, meeting the relevant specifications for saturated vapor pressure.
