In the absorption tower, the gas and liquid phases flow in parallel. 2. There is no difference between primary steam and secondary steam. 3. The fabric medium can affect the filtration speed. 4. Supersaturation is the driving force behind the crystallization process. 5. Freon was a commonly used refrigerant in the past, and it generally does not pollute the environment. 6. The expansion valve can create a throttling effect, thereby achieving pressure and temperature reduction. 7. Changes in the temperature of the medium-temperature shift catalyst bed can be determined by changes in the “sensitivity point” temperature, while the control of the catalyst temperature is based on the “hot spot” temperature. 8 With the same reactant and different catalysts, the same product is obtained, but the reaction rates differ. The 9 ammonia synthesis tower is a multi-stage adiabatic fixed-bed catalytic reactor. 10 The gasification reaction of solid fuels in gas generators is a heterogeneous catalytic reaction.
