Catalyst fines – cat fines for short – remain in marine fuels during refining, as a part of the mandatory cracking practice and the aim of reducing sulfur levels to ecological standards. Unfortunately, cat fines are highly abrasive and difficult to remove from on-board fuel even with diligent cleaning and purification procedures. Embedding in engine parts, they cause wear and destruction.
As shown in Fig. 4, under the dewatering condition, the p-ADPA conversion remained above 95% after the catalyst reused 10 times. However, significant decrease of p -ADPA was obtained under the normal and additional water added conditions with the increase of catalysts reused times, which might be inferred some relations between the catalyst deactivation and the water content of the reaction ...

activated carbon, catalyst fines, and traces of metal oxides and silicas. A ... A significant breakthrough was achieved when filter cake dewatering was evaluated. The MOTT HyPulse LSI filter produced a drier cake than the filter press. The liquid content of the discharged solids was reduced by one-fifth; adding two benefits: (a) increased yield of polyol esters and (b) significant improved ...
plan not to use machinery in excavations while dewatering is taking place minimise water entering the excavation, for example from rainfall, runoff, groundwater ingress or high water table
10/10/2016 For sludge dewatering, using a belt filter press, I can now add another unique and impressive piece of equipment which is the Crown Press shown in the image below. The Crown Press is a laboratory scale (benchtop) belt filter press (BFP). With this press you obtain sludge feed (primary sludge, primary + waste activated sludge, or digested sludge) from a treatment plant which you then
Construction Dewatering Construction projects that extend below groundwater level present particular challenges. If groundwater is not adequately controlled then excavations may flood or become unstable, and the efficiency of construction operations will be reduced, wasting time and money. Construction dewatering is the range of techniques used to control groundwater to allow excavations ...

Therefore, the sludge biochar can be produced via cost-effective and eco-friendly approaches to immobilize harmful components from sludge and remediate organic pollution in wastewater, offering a sustainable route toward sludge reutilization into value
30/12/2009 The following steps were taken to recover the iron catalyst from the sludge—(1) dewatering: the raw sludge was dewatered by vacuum filtration employing a glass–fiber filter; (2) drying: the wet sludge cake/filter was dried in a drying oven at 105 ± 1 °C for 3–4 h; (3) baking: kept the dry sludge cake/filter in a muffle furnace at 300–500 °C for 10–60 min to burn off the adsorbed ...
The invention provides a capturing settling agent and a method for removing catalyst solid powder in oil slurry, the capturing settling agent comprises the following components by weight percent: 0-50% of alkyl R quaternary ammonium salt, 0-40% of flocculant solution and 0-100% of polyol. The method accelerates the settling speed of the catalyst solid powder in the FCC oil slurry by adding the ...

Additionally, smaller diameter secondary hydrocyclones process the primary gypsum dewatering hydrocyclone overflow. The secondary overflow is a chloride/inert fines purge stream that is treated in a waste water plant to maintain the fines and chloride levels in the process. OIL REFINERY. Solids from Water: • Waste water grit removal and clean-up • Coke fines removal from cutting water and ...
A catalyst screening unit having a housing which receives incoming feed catalyst under positive pressure, a screen for sizing and separating whole catalyst from broken catalyst, dust, and fines, a vibrating member to vibrate the housing and the screen therewith, and a lower, waste chamber for collecting broken catalyst and fines to be directed outwardly therefrom the housing, and having
The equipment fleet includes a range of self-priming centrifugal dewatering pumps, a range of bore hole deep well pumps as well and a full selection of dewatering accessories. Our WellPoint dewatering system is the most versatile form of dewatering, capable of dealing with a wide variety of ground conditions from very fine sands to coarse sands and gravel. Using an appropriate groundwater ...
The typical filter press dewatering system includes the filter press, sludge feed pumps as well as sludge storage and/or sludge conditioning tanks with slow speed mixers, sludge transfer pumps, chemical feed, storage equipment, necessary piping, valves, and controls. Two types of filter press systems are available: a) High Pressure (i.e. 225 PSI or 16 Bar) b) Low Pressure (i.e. 100 PSI or 7 ...
A producer of detergent intermediates removes a metal-based fine catalyst from hydrogenation batches with a centrifuge. The reaction slurry contains around 10 wt.% catalyst mass with 20 – 40 µm average particle size; depending on the age of catalyst, there could be fines present below 1 µm in size.
