Offset processing

In 1996, PNL estimated that a 100-ton-per-day facility using 0.06/kWh of electricity would cost approximately 125 per ton. Wastes with some energy content can be processed at much lower costs. For example, ash with high carbon content may cost less than 50 per ton to process. There is also the possibility that the waste form produced could be sold as construction materials or for some other application to offset processing costs (D126034). 

In 1992, researchers developed an engineering and costing design for a fixed unit that operated at a rate of 2 tons per hour. Costs were estimated to be 149 (Canadian) per metric ton of soil treated. This estimate was based on the following assumptions the unit used medium naphtha as a solvent operations were 24 hours per day, for 260 days per year utilization factor of the facility was 83% capital costs were 2,548 million (Canadian) and capital amortized over 10 years at 10%, two payments per year. The estimate stipulated that the recovered oil was of suitable quality to be sold to offset process costs. It was estimated that the largest component of process costs would be labor ( 56 per ton of waste treated). Other cost components listed were capitalization costs ( 38 per ton), utilities ( 29 per ton), insurance ( 9 per ton), trucking and maintenance (each 5 per ton), equipment rental and site excavation and restoration (each 3 per ton), and waste disposal was estimated to cost 1 per ton (D17896F, p. 8).

A third emission reduction choice is to remain with the existing front end process, which continues to produce a sulfur dioxide-containing waste gas stream, and move to some system which can effectively remove the sulfur dioxide from this waste gas before it is discharged. Many methods are available, each with features which may make one more attractive than the others for the specific sulfur dioxide removal requirements (Table 3.8). Some of the selection factors to be considered are the waste gas volumes and sulfur dioxide concentrations which have to be treated and the degree of sulfur dioxide removal required. It should be remembered that the trend is toward a continued decrease in allowable discharges. The type of sulfur dioxide capture product which is produced by the process and the overall cost are also factors. Any by-product credit which may be available to offset process costs could also influence the decision. Finally, the type of treated gas discharge required for the operation (i.e., warm or ambient temperature, moist or dry, etc.), also has to be taken into account. Chemical details of the processes of Table 3.8 are outlined below. 

Non-contact printing—there is neither direct nor indirect contact (e.g. offset processes). Examples ink jet and laser printing. 

International offsets remain controversial with some political constituencies in the USA. Nevertheless, the Waxman-Markey bill signals an openness to both significant use of international offsets (i.e. 1 billion tons/year) as well as reform of the international offset process. In particular, the development of criteria to provide credits on a sectoral basis could be an area of future collaboration between the USA and the EU. 

The value of this response time analysis (RTA) is that is can be easily modified to accommodate a variety of application characteristics and platform constraints (Burns, 1994), including irregular release patterns, phased executions (i.e offsets), processes with multiple deadlines, processes with forward or backward error recovery, soft and firm deadlines, aperiodic processes, etc. The necessary mutual exclusive protection of shared state data is provided by priority ceiling protocols. 

Manx Stone. See china stone. Marbleized. A vitreous-enamel finish resembling marble it can be obtained by an offset process from natural marble. Marbling. A procedure sometimes used by the studio potter the marble effect is obtained by covering the piece of previously dried ware with coloured slips and then shaking the ware (while the slips are still wet) to make the colours run into one another. 

The importance of letterpress printing today is very much reduced by the cold-set offset process, whereby most of the newspapers are printed. Conventional newspapers are uncoated papers, based on recovered and deinked printing papers and/ or mechanical pulps. However, a coated surface of such a newspaper or another base paper made from a relatively cheap furnish opens new applications for the cold-set web-offset process with significant improved print quality and cost-performance (Fig. 7.7).
