Processing-line downtime

Processing line downtime Refers to equipment that cannot be operate when it should be operating. Reason for downtime could be equipment being inoperative, shortage of material, electric power problem, operators not available, and so on. Regardless of reason, downtime is costly. 

Beginning with this option, process modification requires not only capital and downtime, but also floor space. This can be a significant barrier in many plating operations, and therefore this option is most easily implemented in new facilities or where substantial reconstruction of process lines is taking place. The concept is to use a non-flowing rinse, or empty tank, to capture process solution for eventual return to the process tank, with or without further separation or concentration. It has seen wide application with nickel and chrome plating, and seems to function quite well. Some concerns have arisen, however. 

Improved raw materials procurement and flow by replacing two containers associated with dualcomponent adhesive with a single-component system Elimination of pot life consideration and line downtime resulting from adhesive advancement Elimination of mix ratio tolerance concerns with resulting improvement in product consistency Elimination of variations from the coating process with resulting improvement in product consistency Improved worker safety and reduced hazardous materials exposure to liquid and paste systems... 

Process streams often operate at high flowrates and these have to be split in order to obtain an acceptable flowrate in the measuring device. This reduction has to be carried out with care in order to minimize sampling errors. Ideally, the whole of the process stream should be examined. Inserting a probe directly into a process line is usually not feasible due to servicing and downtime problems. It is therefore preferable to use a side-stream that can be isolated from the process stream. 

Firing of Enamels. Firing can be carried out in intermittent box-type furnaces or continuous furnaces. The dryer and the furnace form one continuous unit or function as separate units in the continuous firing process. Most industrial furnaces are fiber-lined (low thermal mass), which lowers cost and downtime between firing schedules. 

Pipe-line and marine installations are frequently arranged so that the engine drives all its auxiliaries from the crankshaft by means of chains and V belts. But process-plant practice is to have all the auxiliaries independently driven, using standby pumps to minimize engine downtime. 

Sample preparation is an important and necessary step in the overall analytical process, because most analytical instruments cannot accept the sample matrix directly. If these materials were to be injected, then the consequences may include a rapid deterioration in the separation performance of the chromatographic column, clogged frits or lines that result in an increased system back pressure, and detector fouling that may reduce system performance and result in downtime for cleaning the ionization source.
