The article reports that Poerner Ingenieurgesellschaft's Bi-turox oxidation process converts suitable feedstock blends to road and industrial asphalt/bitumen. The feed blend is optimized to obtain a proper composition to reach the target product quality. The reactor is a vertical pressure vessel equipped with an inner cylinder and a baffle system.BLUM...
Penetration Grades of Bitumen is produced from Vacuum Residue, which is blown by hot air in the Biturox Blowing Unit; The fully automated process runs continuously resulting in a constant and homogeneous finished product quality. Wataniya's Penetration Grade Bitumen can be supplied in any grade ...
The properties of the resulting material, called air-blown or oxidized bitumen, depend on the crude origin (or the soft bitumen) and the operating conditions, especially blowing temperature and time. It remains the best process to make very hard bitumens, especially for waterproofing. For paving...
4. The Finished Blowing Temperature (FBT) is occasionally provided. This is the temperature at which the blowing of the asphalt was completed. Note: Work done by the NRCA has shown that different EVT values should be used for mop-applied vs. machine-applied asphalt. The original EVT is ...
including the proportional blending of various binders, the selection of specific techniques and chemical catalysts (such as air blowing or half air blowing), and the incorporation of additives to modify properties[1]. Refineries employoptimisation strategiesfor these variables to engineer a bitumen that...
The distributor is equipped with automatic blowing device to shift the asphalt outside to the tank. The machine is also equipped with spray gun device to add asphalt at the opposite corner. Asphalt pump, nozzle and asphalt tank can be heated with heat trans...
7.)The distributor is equipped with automatic blowing device to shift the asphalt outside to the tank. Q1: I don't want this configuration! A: Configuration can be changed to meet your detailed demand. Q2: Minimum order quantity? A: MOQ is 1 unit. Q 3: How...
According to the invention, blown bitumens can be manufactured in a blowing unit by passing a stream of air and/or oxygen through a starting bituminous base. This operation may be performed in the presence of an oxidation catalyst, for example phosphoric acid. The blowing is generally performed...
A bitumen blowing method bitumen blowing air into a body of bitumen, subjecting the bitumen to agitation to disperse the air therein to form a mixture of air and bitumen, increasing the intensity of the agitation when the amount of air in the air and bitumen mixture increases, and decreasing...
Incorporation of flux oil in the feed of the blowing bitumen unit tends to increase PAH content in feed stock and in blown bitumen, particularly the 4-to 6-ring PAHs, which are the most carcinogenic as identified by an animal skin painting test. The amount of PAH content from blown ...
