Abstract: A system and method of using the system for controlling oxidation of sulfites to reduce total nitrite and nitrate levels in a slurry is disclosed. The system includes a tank having an inlet for receiving a slurry produced in a wet flue gas desulfurization process. The tank also includes an inlet for receiving a gas. The inlet for receiving the gas is operable to disperse at least a portion of the gas received in the tank through at least a portion of the slurry received in the tank. A sensor is configured to measure a sulfite concentration of the slurry received in the tank to obtain a sulfite concentration measurement. In some embodiments, the sensor is a sulfite analyzer. In other embodiments, the sensor is a virtual analyzer. The system also includes a controller. Software executing on the controller generates an electronic signal affecting an adjustment of a flow rate of gas into the slurry in the tank based at least in part on the sulfite concentration/sulfite concentration measurement.

Abstract: The present invention discloses an airlift reactor assembly with a helical sieve plate, comprising a reaction tank, wherein a draft tube and a gas sparger are assembled in the reaction tank, the gas sparger is arranged just below an riser section of the draft tube, a helical sieve plate is arranged in the riser section of the draft tube, and a body of the helical sieve plate is helical upwards to guide a part of two/three-phase flow in the riser section, and the body of the helical sieve plate is provided with a plurality of sieve meshes to guide the remaining two/three-phase go through the helical sieve plate in the riser section and to break bubbles. The present invention gives consideration to both macroscopic mixing and microscopic mixing processes. In addition to driving liquid to circularly flow by using ejected gas, the helical sieve plate can be used for breaking large bubbles into small bubbles thereby effectively preventing the bubbles from coalescing, increasing gas holdup and increasing a volumetric oxygen transfer coefficient.

Abstract: A process for increasing alcohol yield from biomass (the form or agro- or forest residue, grains, hops, etc.), involving multiple hydrodynamic cavitation treatments of biomass filtrate—both before and after fermentation. Carbohydrates extracted from biomass are subjected to a first cavitation treatment to promote additional conversion into carbohydrates. The carbohydrates are then combined with bacterial species and nutrients, and allowed to ferment. The fermentation product is subjected to a second hydrodynamic cavitation treatment to promote further conversion of carbohydrates into bioalcohol. After distillation, the bioalcohol is subjected to a second hydrodynamic cavitation treatment to increase its purity.
