The four principles that must not be violated in the operation of equipment in chemical production are: the four principles are ( ), ( ), ( ), ( ). 2. When studying gas-liquid phase equilibrium, there are two important laws, namely: ( ) and ( ). 3. The solubility of carbon dioxide in methanol decreases as the temperature drops, and increases as the pressure rises. 4. Under low-temperature and high-pressure conditions, methanol has a high absorption capacity for ( ) and ( ) in raw gas, while it has a lower solubility for ( ) and ( ). 5. In the sulfur recovery unit, one-third of the hydrogen sulfide present in the acidic gases coming from the desulfurization unit can be oxidized to (), and together with the unoxidized hydrogen sulfide, it enters the converter where it undergoes catalytic conversion to form (). Answer: 1. Do not exceed the temperature limit, do not exceed the pressure limit, do not exceed the speed limit, do not exceed the load limit. 2. Answer: Raoult’s law and Henry’s law. 3. Answer: Increase, increase. 4. Answer: H2S with CO2, H2 with CO. 5. Answer: Sulfur dioxide, elemental sulfur. It should be noted that respondents are required to keep their answers hidden. If the answerer’s score is not hidden, it is halved. For methods to hide posts, see: http://bbs.hcbbs.com/thread-1551107-1-1.html
1. Overtemperature, overpressure, overspeed, overload； 2. Raoult’s law, Henry’s law ； 3. Increase, increase ； 4. Hydrogen sulfide and carbon dioxide, hydrogen and carbon monoxide ； 5. Sulfur dioxide, elemental sulfur
1. The four prohibitions regarding equipment operation in chemical production are: the four prohibitions are (no overheating), (no overpressure), (no overspeed), and (no overload). 2. When studying gas-liquid phase equilibrium, there are two important laws, namely: (Raoult’s law) and (Henry’s law). 3. The solubility of carbon dioxide in methanol (increases) as the temperature decreases, and it also (increases) as the pressure rises. 4. Under low-temperature and high-pressure conditions, methanol has a high absorption capacity for (H2S) and (CO2) in raw gas, but a lower solubility for (H2) and (CO). 5. In the sulfur recovery unit, one-third of the hydrogen sulfide present in the acidic gases coming from the desulfurization unit can be oxidized to sulfur dioxide; this sulfur dioxide, along with the unoxidized hydrogen sulfide, enters the converter where it undergoes catalytic conversion to produce elemental sulfur.
