Inventors include Zhang, Yue; Cogswell, Martin A.; Jackson Jr. , William L.; Krinock, Robert J.; Pretz, Matthew T.; Holderness, John; and Dillon, John J..
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: A method for processing a mixed stream may include compressing the mixed stream to form a compressed mixed stream. The mixed stream includes one or more of C2, C3, and C4 hydrocarbons and H2O. The method may include cooling the compressed mixed stream to form a cooled mixed stream and separating the cooled mixed stream into at least a first fraction and a second fraction. The method may include at least partially drying the first fraction such that at least a portion of the H2O is removed from the first fraction to form a dried first fraction that has a lower H2O concentration than the first fraction. The method may further include compressing the dried first fraction to form a compressed dried first fraction, cooling the compressed dried first fraction to form a cooled dried first fraction, and passing the cooled dried first fraction to a separation unit.
