Abstract: A process for preparing benzene containing less than 1 ppm (wt) dioxane from an aromatic stream containing benzene which is contaminated with dioxane, the process including providing an aromatic stream containing benzene which is contaminated with dioxane; subjecting the aromatic stream to liquid phase adsorption by contacting an adsorbent contained in at least one column, which adsorbent comprises at least one substance selected from the group consisting of molecular sieves and clay; and recovering benzene containing less than 1 ppm (wt) dioxane. Preferably, the liquid phase adsorption is carried out at a pressure ranging from atmospheric pressure to 20 kg/cm.sup.2 and at a temperature ranging from ambient temperature to 50.degree. C. Preferably, the molecular sieves have a pore size of 10 .ANG.. The process may further include regenerating the adsorbent by passing a flow of nitrogen gas through the adsorbent at a temperature ranging from 200 to 300.degree. C. Alternatively, the process may further include regenerating the adsorbent by heating the adsorbent at a temperature ranging from 200 to 300.degree. C. for a period of time which is effective to regenerate the adsorbent.

Abstract: A system (1) for determining a load of a vehicle such as a HGV. The system (1) comprises a plurality of strain gauges (2) mounted on each axle (3, 4) of the HGV. Each strain gauge (2) is arranged parallel to the longitudinal axis A-A of the axles (3, 4) to measure the strain exerted on each axle (3, 4) in a direction substantially parallel to the longitudinal axis A-A of each axle (3, 4). The strain gauges (2) are mounted on the axles (3, 4) at locations on the axles (3, 4) at which the axles (3, 4) exhibit a substantially linear strain-load relationship. These locations are determined, by performing a finite element analysis of the axles (3, 4). The system (1) also comprises a master control unit (5), carried on-board the HGV5 for calculating the HGV load responsive to the longitudinal strain measured by the strain gauges (2). The load exerted by the HGV on the road surface may then be calculated responsive to the calculated HGV load. The strain gauges (2) may be employed to measure in real-time the longitudinal strain exerted on the nodes (3, 4) of the HGV while the HGV is moving, and the master control unit (5) may be employed to calculate in real-time the HGV load while the HGV is moving. The system (1) further comprises a transmitter for transmitting information from the HGV to a central server at a location remote from the HGV.
