Site plant effectiveness

Evaluate Effectiveness on the Basis of Outputs and Acceptance Once the system has been implemented on its chosen site, its effectiveness needs to be evaluated at frequent intervals so that corrective action can be taken in the event of problems. The first criterion for success is that the system must generate unique insights into the causes of errors and accidents, which would not otherwise have been apparent. Second, the system must demonstrate a capability to specify remedial strategies that, in the long term, lead to enhanced safety, environmental impact and plant losses. Finally, the system must be owned by the workforce to the extent that its value is accepted and it demonstrates its capability to be self-sustaining.

However, site services and infrastructure are not only a major driver of cost competitiveness. Some of the services are also crucial for improving plant effectiveness. Maintenance performance, for instance, can have a huge impact on plant output. Unplanned breakdowns, often caused by failure to implement the most effective maintenance strategy or by poor execution, can lead to as much as a 20 percent loss in overall equipment effectiveness (OEE see also Chapter 18). On the utilities side, significant cost advantages can be captured, e.g., by providing... 

Site services and infrastructure have a strong impact on total production costs and plant effectiveness, and in times of increased changes of ownership of chemical assets their organizational flexibility is becoming more and more relevant. 

Core elements of chemical SCs considered in integrated planning approaches at the tactical/strategicaf level are capacities and parameters of the production systems and the logistical systems (e.g. turnover or inventory capacities). Since sites and plants are interconnected, local adjustments more or less immediately affect the remaining sites/-plants. Integrated approaches capture these spill-over effects by a combined modelling of the interdependent components. 

Oviposition frequently involves a complex series of stimuli, many of which are chemical. Further, because many larvae are relatively immobile, selection of the host plant effectively occurs when the gravid female selects a site for oviposition (Renwick, 1988). However, many factors other... 

Parts of site plant and equipment can easily intrude into public highways, sometimes with disastrous effect. Buckets and counterweights should not be allowed to swing into roadways or pedestrian areas, even with the presence of a banksman (who may be momentarily distracted). 

OP compounds have been reported to be the most effective inhibitors against plant PDHc El among oAict PDHc inhibitors. Optimal OP compounds therefore could be an effective, environmental friendly, and selective herbicides targeting on a novel mode of action site (plant PDHc El), which is different from the target of commercial herbicide.

Transuranic Waste. Transuranic wastes (TRU) contain significant amounts (>3,700 Bq/g (100 nCi/g)) of plutonium. These wastes have accumulated from nuclear weapons production at sites such as Rocky Flats, Colorado. Experimental test of TRU disposal is planned for the Waste Isolation Pilot Plant (WIPP) site near Carlsbad, New Mexico. The geologic medium is rock salt, which has the abiUty to flow under pressure around waste containers, thus sealing them from water. Studies center on the stabiUty of stmctures and effects of small amounts of water within the repository. 

Emissions control systems play an important role at most coal-fired power plants. For example, PC-fired plants sited in the United States require some type of sulfur dioxide control system to meet the regulations set forth in the Clean Air Act Amendments of 1990, unless the boiler bums low sulfur coal or benefits from offsets from other highly controlled boilers within a given utiUty system. Flue-gas desulfurization (FGD) is most commonly accomphshed by the appHcation of either dry- or wet-limestone systems. Wet FGD systems, also referred to as wet scmbbers, are the most effective solution for large faciUties. Modem scmbbers can typically produce a saleable waUboard-quaUty gypsum as a by-product of the SO2 control process (see SULFURREMOVAL AND RECOVERY). 

The cost of transportation has an important effect on the marketabiUty of chemicals. For that reason, transportation, along with numerous other factors, is often a significant consideration in determining the location of chemical production faciUties. In addition, convenient and economical access to water and rail transportation and the interstate highway system, as well as proximity to raw materials and markets, may influence the choice of warehouse and terminal sites for storage and redistribution of chemical products (see Plant location).
