20100319541 | GAS FILTRATION SYSTEM - A gas filtration system includes a liquid filtering system and a gas transferring system. The liquid filtering system has multiple tanks connected to each which contains a gas scrubbing liquid through which the gas is bubbled. The gas transferring system includes pipes coupled with the tanks for transferring gases. The tanks include a dry tank that is used for storing one or more of pumps, filters and a gas flow buffer. | 12-23-2010 |
20100319542 | SCRUBBING OF AMMONIA WITH UREA AMMONIUM NITRATE SOLUTION - A process for scrubbing ammonia in a CO2 removal process having the steps of absorbing ( | 12-23-2010 |
20120304859 | PROCESS AND DEVICE FOR GAS SCRUBBING - The invention relates to a process and a device for carrying out a gas scrubbing, in which gas is conducted from bottom to top and scrubbing medium is conducted from top to bottom through a scrubbing column (T). In the scrubbing column (T) at least two scrubbing sections (WS | 12-06-2012 |
20140245889 | SYSTEM AND METHOD FOR REMOVING CONTAMINANTS FROM A CONTAMINATED GAS STREAM - A system for removing contaminants from a contaminated gas stream using a liquid absorbent, the system having a first and a second separation unit. The first separation unit includes a first separator having an inlet for a contaminated gas stream to be separated, a first outlet for separated gas and a second outlet for separated liquid absorbent; a rising conduit for transporting the contaminated gas stream to the inlet of the first separator; a conduit for removing the separated gas at the first outlet of the first separator; and a conduit for removing separated liquid absorbent at the second outlet of the first separator. The second separation unit includes a second separator having an inlet for a stream to be separated, a first outlet for separated gas and a second outlet for separated liquid absorbent; a rising conduit for transporting a contaminated stream to the inlet of the second separator; a conduit for removing separated gas at the first outlet of the second separator; and a descending conduit for removing separated liquid absorbent at the second outlet of the second separator. The descending conduit of the second separation unit is fluidly connected to the rising conduit of the first separation unit and the height of the descending conduit of the second separation unit is selected such that during use the hydrostatic force in the descending conduit of the second separation unit can induce the liquid absorbent in the rising conduit of the first separation unit to flow to the inlet of the first separator. | 09-04-2014 |
20140366729 | Method for Recovering Ethylene during the Process for Producing VAC and a Device thereof - The present invention discloses a method and a device for recovering ethylene during the process for producing vinyl acetate, wherein a double solvent absorption method composed of an absorbent solution and deionized water is adopted. The method is as follows: introducing an outlet stream as an absorbent solution from the upper section of the feeding plate in an acetic acid tower during the rectification stage of vinyl acetate production; delivering same to the top of the lower section of the ethylene recovery tower by a delivery pump; charging refined gas from the tower bottom of the ethylene recovery tower for contacting with the absorbent solution in a counter-current; delivering the absorption bottom solution to the rectification stage for treatment; the gas continuing to rise to the upper section of the ethylene recovery tower and contacting with the deionized water introduced from the top of the tower in a counter-current; absorbing and removing the acetic acid therein; and discharging the residual inert gas, such as N2, from the top of the ethylene recovery tower. The absorbent solution is a mixture of acetic acid, vinyl acetate and water, and comprises by weight percentage of 50-85% acetic acid, 5-30% vinyl acetate and 5-20% water. | 12-18-2014 |
