Treatment of CS2 in waste gas from rubber refining by gas cyclone-liquid jet separator

Simultaneous Removal of SO2 and NO from the Flue Gas of Marine Ships with a Gas Cyclone–Liquid Jet Absorption Separator

“…According to the two-film theory, mass transfer is dominated by the gas film for both SO 2 and NO. ,− K G is approximately equal to k G , as shown in formulas and . In addition, as both the flue gas and the injected absorbent were rotating in the GLAS, the back-mixing could be ignored, the absorbent and the flue gas in the GLAS could be regarded as the plug flow, and the total mass transfer coefficient K G a for both SO 2 and NO could be calculated through formula ; H is the Henry coefficient, kPa·m 3 ·mol –1 ; k G is the mass transfer parameter of the gas phase, kmol·m –2 ·s –1 ·kPa –1 ; k L is the mass transfer parameter of the liquid phase, kmol·m –2 ·s –1 ·kPa –1 ; K G a is the overall mass transfer coefficient of the gas phase, mol·m –3 ·s –1 ·Pa –1 ; t is the gas–liquid contact time, s; R is the ideal gas constant, 8.314 J·mol –1 ·K –1 ; T is temperature, K; V G is the gas flow rate, m 3 ·s –1 ; and V mid is the clearance volume of GLAS, m 3 . …”

“…Furthermore, the absorbent continuously swirls inside the GLAS, making it less prone to scaling and clogging, which facilitates installation and maintenance. 42,43 The high mass transfer coefficient indicates that GLAS can achieve a high removal efficiency with a cheap NaClO solution and with a small volume. Therefore, GLAS has great application prospects for marine ships.…”

“…The multistep process of gas–liquid impingement, reaction, and separation is performed simultaneously in the static GLAS, which gives the GLAS a simpler structure than the RPB and a much higher mass transfer coefficient than the VFS. Furthermore, the absorbent continuously swirls inside the GLAS, making it less prone to scaling and clogging, which facilitates installation and maintenance. , The high mass transfer coefficient indicates that GLAS can achieve a high removal efficiency with a cheap NaClO solution and with a small volume. Therefore, GLAS has great application prospects for marine ships.…”

Study on the Jet-Cyclone Coupled Separation Performance of Solvent Naphtha Containing MDEA

“…Numerous solvent naphtha desulfurization technologies have been developed, with dry and wet desulfurization being the most prominent ones. − As a widely used desulfurization process, amine desulfurization has a good desulfurization effect, minimal solvent loss, and low corrosion to equipment . However, solvent naphtha and MDEA are fully mixed in the lye tank during the desulfurization process.…”
