Title:
AUTOMATIC HEAVY OIL FOUR-COMPONENT SEPARATION APPARATUS AND SEPARATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/083066
Kind Code:
A1
Abstract:
An automatic heavy oil four-component separation apparatus and a separation method thereof. The separation apparatus comprises a solvent storage tank (1), a heavy oil four-component separation unit (100), and a receiving apparatus (9). The heavy oil four-component separation unit (100) comprises a filter disc (4), one end of which being communicated with the solvent storage tank (1), and the other end of the filter disc being communicated with the inlet of a pre-column flow path switching valve (5); and a chromatographic column (6), the inlet thereof being communicated with the outlet of the pre-column flow path switching valve (5), and the outlet of the chromatographic column being communicated with the inlet of a post-column flow path switching valve (8). The receiving apparatus (9) is communicated with the outlet of the post-column flow path switching valve (8). Asphaltene can be separated online by means of the filter disc (4), parallel flow distribution and preheating of a multi-path solvent can be achieved, and a multi-path eluent can be automatically received and the solvent can be quickly evaporated, so that the automatic and rapid separation of the heavy oil four-component is achieved, thereby saving time, reducing operation errors caused by labor, and improving the precision of separation and measurement.
