Water separation – Exam in the third week of March. Name: Score: I. Fill in the blanks (1.5 points each) 1. When the vaporization furnace’s pressure is raised to 2.0 Mpa, the ____________ pipeline is connected to the dust-containing gas water pipeline in order to put it into use. 2. To supply high-pressure jet gas water to unit 609# and receive the oil-containing gas water from that unit, the J623A02 pump needs to be started; ____________ must also be put into use. 3. The steps for starting the J623A02 pump are as follows: Open the valve, then open another valve; once water starts flowing, close that valve. Start the J02 pump, and after the flow rate stabilizes, slowly open another valve. Once water starts flowing, open the outlet valve. Close that valve once the pressure reaches 1.8 Mpa. 4. When filling the cooling water into the dust-containing gas-water cooler with C623ABCD02ABCR, open the valve first; once water flow is established, open another valve and then close it. 5. During the initial startup process for filling the liquid level in the oil-containing gas-water system, the sequence of operating the filling equipment is as follows. 6. F26 should be backwashed once a day; when the liquid level in F05 rises above the set limit, start the pump to send fluid to F24. 7. The working principle of the gas-water separation unit relies on the differences between various components, thereby separating oil and dust-containing tar from the gas water mixture. By utilizing the principle that decreasing pressure reduces the solubility of gases in liquids, the gases such as , , and others dissolved in coal gas water are separated through flash depressurization. 8. Control the temperature of the gas and water at the CO2 outlet to prevent emulsification of the gas and water inside the separator, which could affect the separation efficiency. If emulsification needs to be eliminated through temperature adjustment, it is possible to mix certain components together and feed them into F24 to improve the separation effect. 9.609# and 613# have stopped supplying oil-containing gas, water, gas water, and condensate to 623#; the boundary valves leading to 623# were closed to prevent any leakage. N2 was introduced into the lines carrying expanded gas, thereby purging the entire pipeline until it was confirmed that the outlet gas contained no such substances. 10. For parking the F22 and F21, when discharge is required, open the bottom valves of F21 and F23. 11. When stopping F24 and F23, open the valve used to purge the pipeline, purge F24, and close it once it is satisfactory. 12. When stopping the F25, close the internal pipelines and external valves. 13. In accident handling, the expansion of oil-containing gas and water to the pressure in the expansion gas cooler lines is caused by air leakage. 14.
