In one aspect, the system has an apparatus for at least partially depressurizing and cooling the high pressure, high temperature dense phase solids stream having gas entrained therein and a pressure letdown device for further depressurization and separating cooled coarse solid particles from a portion of the entrained gas, resulting in a lower temperature, lower pressure outlet of solid particles for downstream processing or discharge to a storage silo for future use and/or disposal. There are no moving parts in the flow path of the solids stream in the system.

摘要： Disclosed are apparatus and method to treat large amounts of flue gas from a pulverized coal combustion power plant. The flue gas is contacted with solid sorbents to selectively absorb CO2, which is then released as a nearly pure CO2 gas stream upon regeneration at higher temperature. The method is capable of handling the necessary sorbent circulation rates of tens of millions of lbs/hr to separate CO2 from a power plant's flue gas stream. Because pressurizing large amounts of flue gas is cost prohibitive, the method of this invention minimizes the overall pressure drop in the absorption section to less than 25 inches of water column. The internal circulation of sorbent within the absorber assembly in the proposed method not only minimizes temperature increases in the absorber to less than 25° F., but also increases the CO2 concentration in the sorbent to near saturation levels. Saturating the sorbent with CO2 in the absorber section minimizes the heat energy needed for sorbent regeneration. The commercial embodiments of the proposed method can be optimized for sorbents with slower or faster absorption kinetics, low or high heat release rates, low or high saturation capacities and slower or faster regeneration kinetics.
摘要翻译：公开了从粉煤燃烧发电厂处理大量烟道气的设备和方法。烟道气与固体吸附剂接触以选择性吸收二氧化碳，然后在较高温度下再生时将CO 2作为几乎纯的CO 2气流释放。该方法能够处理数千万磅/小时所需的吸附剂循环速率，从发电厂的烟道气流中分离二氧化碳。因为对大量烟道气的加压是成本高昂的，所以本发明的方法将吸收部分的总体压降最小化到小于25英寸的水柱。在所提出的方法中，吸收器组件内的吸附剂的内部循环不仅使吸收器中的温度升高最小化到小于25°F，而且还将吸附剂中的CO 2浓度增加到接近饱和水平。吸收器部分用CO2饱和吸附剂使吸附剂再生所需的热能最小化。所提出的方法的商业实施方案可针对具有较慢或更快吸收动力学，低或高放热速率，低或高饱和容量以及较慢或更快再生动力学的吸附剂进行优化。
