The paper presents the results of an analysis of a two-stage pilot plant for the removal of toluene and benzene from the exhaust air of an industrial wastewater treatment plant (WWTP). The two-stage air process combines a water scrubber and a biotrickling filter (BTF) in sequence, and treats air stripped from the liquid phase compartments of the WWTP. During the experimental period, the pilot p...

A Pease-Anthony Venturi scrubber is a gas cleaning device that uses liquid, injected in the equipment as jets, to remove contaminants from the gas. The liquid jet is atomized into droplets, which are dispersed throughout the equipment due to the turbulence. The performance of the scrubber is affected by the spatial distribution of the droplets. Although CFD models have been used to predict the ...

The article analyses the investments efficiency of sulphur oxide (SOx) scrubber installation to comply with the requirements of MARPOL 73/78 Annex VI, which sets 0.1% SOx limits in 2015 in Emission Control Area (ECA) and 0.5% in 2020 globally. There are two most realistic technologies to reduce SOx emission suitable for existing fleet: low sulphur fuel; scrubber. Mentioned technologies are comp...

The HP scrubber is an equipment used to separate liquid from gas in the oil and industry. low level vessel one of abnormal conditions scrubber, a blowby event will happen because level. So, controller indicator required prevent system damage workplace accidents. alarm response time calculated order avoid accident. To determine for dynamic process simulation method can be using Aspen HYSYS versi...

SRAM-based FPGAs are sensitive to radiation effects. Soft errors can appear and accumulate, potentially defeating mitigation strategies deployed at the Application Layer. Therefore, Configuration Memory scrubbing is required to improve radiation tolerance of such FPGAs in space applications. Virtex FPGAs allow runtime scrubbing by means of dynamic partial reconfiguration. Even with scrubbing, i...

A Venturi scrubber has dispersed three-phase flow of gas, dust, and liquid. Atomization of a liquid jet and interaction between the phases has a large effect on the performance of Venturi scrubbers. In this study, a computational model for the interactive three-phase flow in a Venturi scrubber has been developed to estimate pressure drop and collection efficiency. The Eulerian-Lagrangian method...

Tobacco dust represents a critical threat to the operators’ respiratory health. Even when wet scrubbers display high purification efficiencies and strong adaptability dust, their potential applications in tobacco industry have not been studied. In present research, removal efficiency of scrubber for fine were examined at laboratory industrial level. Results showed that under conditions reached ...

In principle, the installation of emissions abatement technology (otherwise known as scrubbers) on ships would reduce air pollution and premature deaths from disease and allow vessels to save costs by continuing to burn cheap high-sulphur residual fuel oil. But very few scrubbers have been installed. A recent House of Commons Select Committee Inquiry was unable to decide between the competing t...

A mathematical model has been developed for the prediction of the collection efficiency of submicron particles in the conduit type scrubber. The model has been tested with the data in the literature [1,3].

Removal of fly ash using wet scrubbers is widely used in the small and medium scale industries. Among the wet scrubbing methods, spray column falls into the simplest type category for its simple construction and various advantages. A novel pilot plant wet scrubber has been conceived, designed and fabricated. This paper distinctly focuses on the detailed design and fabrication of the ejector, wh...
