When not being then exhausted from, the connecting tube of cold-trap and the 4th high pressure valve is separated, beaker is placed in the outlet of the 4th high pressure valve and is used to
Collect solution；The 4th high pressure valve is closed, the first high pressure valve is opened, then starts solution pump, methylene chloride is injected into sample
In product cylinder and pipeline, pressure is made to reach 10MP；10 minutes are stood, the 4th high pressure valve is slowly opened, makes the solvent containing petroleum
It is discharged in beaker；When the solvent of discharge is completely colorless, and with fluorescent lamp without it is luminous when, it is believed that cleaned up, stopped
Only solvent injects；The first high pressure valve is closed, sample cylinder is heated to 40 DEG C, remaining solvent is evaporated into discharge, is closed after the completion
Close electric furnace；
S5: solid sample takes out: jack declined, tubular electric furnace is separated in half, and then sample cylinder separated with system,
Plunger and graphite-seal ring are moved up and down with tool taking-up；Sample is taken out with mandril；Experiment is completed.
Further, the leakproofness of system can be examined as follows in the step S1: a, to be first turned on second high
Pressure valve, third high pressure valve, starting water pump are forced into 50MP to experimental system water filling, close the second high pressure valve and keep 1
Hour；If the reduction of pressure is less than 0.1MP and each interface of pipeline is without visual visible leakage, then it represents that pressure system sealing is good
It is good, execute step b；If pressure system seals bad, return step S1, each component and again assembly and connection are checked；B, heating row
Water: disconnecting the connection of the 4th high pressure valve and cold-trap, places water receiving container in the 4th high pressure valve exit；Open the 4th high pressure
Valve, allows water discharge system in sample cylinder, while starting electric furnace heating, is raised to 150C, constant temperature by the heating rate of 100C/h
