Operations sustainability

Engineering is based on fundamentals and the dynamic balance among economic, operability, sustainability, safety, environmental, legal, ethical, and time constraints. It is dynamic, because the development of new technology, catalysts, and materials of construction, and the shifting economical, social, and political scenes, mean that the processes we develop, improve, and operate in the future will be dramatically different from past practice. We say it is based on fundamentals, because mass, energy, momentum, and charge will still be conserved.

Awarded to recognize best practices and real achievements in reduction, the Carbon Trust Standard helps organizations to measure, manage, and reduce their environmental impact, whilst improving their resource management and operational sustainability (Carbontrust).

A company operates sustainably when its actions do not impair the planet s ability to provide the necessary resources in both the present and the future and when it integrates, on a voluntary basis, social and environmental concerns in its business operations and its interactions with its stakeholders. This is a commitment to find a healthy balance between financial, environmental and social imperatives, without compromising the development opportunities of...

Despite the benefits of supplier rationalisation and focused factories, risk management does imply there is real rationale for lining up alternative suppliers in different locations and for manufacturers to develop a thorough understanding of their suppliers capabilities and vulnerabilities. Companies are responding in two ways consider alternative and back-up sources and proactively audit the supply base for financial and operational sustainability in these tough times. Hewlett-Packard, for example, has secondary suppliers for all critical components as part of its continuity plan.

A belted-in operator will sustain more head injury from hitting the floor, and as much as an unbelted operator sustains from hitting the overhead guard. 

The purpose of chemical processes is not to make chemicals The purpose is to make money. However, the profit must he made as part of a sustainable industrial activity which retains the capacity of ecosystems to support industrial activity and life. This means that process waste must be taken to its practical and economic minimum. Relying on methods of waste treatment is usually not adequate, since waste treatment processes tend not so much to solve the waste problem but simply to move it from one place to another. Sustainable industrial activity also means that energy consumption must be taken to its practical and economic minimum. Chemical processes also must not present significant short-term or long-term hazards, either to the operating personnel or to the community. 

Diflfiisive processes nonnally operate in chemical systems so as to disperse concentration gradients. In a paper in 1952, the mathematician Alan Turing produced a remarkable prediction [37] that if selective diffiision were coupled with chemical feedback, the opposite situation may arise, with a spontaneous development of sustained spatial distributions of species concentrations from initially unifonn systems. Turmg s paper was set in the context of the development of fonn (morphogenesis) in embryos, and has been adopted in some studies of animal coat markings. With the subsequent theoretical work at Brussels [1], it became clear that oscillatory chemical systems should provide a fertile ground for the search for experimental examples of these Turing patterns. 

Therefore, if a large quantity of sample is introduced into the flame over a short period of time, the flame temperature will fall, thus interfering with the basic processes leading to the formation and operation of the plasma. Consequently introduction of samples into a plasma flame needs to be controlled, and there is a need for special sample-introduction techniques to deal with different kinds of samples. The major problem with introducing material other than argon into the plasma flame is that the additives can interfere with the process of electron formation, a basic factor in keeping the flame self-sustaining. If electrons are removed from the plasma by... 

Water Quality. AH commercial oil shale operations require substantial quantities of water. AH product water is treated for use and operations are permitted as zero-discharge facHities. In the Unocal operation, no accidental releases of surface water have occurred during the last four years of sustained operations from 1986 to 1990. The Unocal Parachute Creek Project compliance monitoring program of ground water, surface water, and process water streams have indicated no adverse water quaHty impacts and no violations of the Colorado Department of Health standards (62). 

LDPE, also known as high pressure polyethylene, is produced at pressures ranging from 82—276 MPa (800—2725 atm). Operating at 132—332°C, it may be produced by either a tubular or a stirred autoclave reactor. Reaction is sustained by continuously injecting free-radical initiators, such as peroxides, oxygen, or a combination of both, to the reactor feed.
