A Chemical plant is an industrialprocessplant that manufactures chemicals, usually on a large scale. Petrochemical plants are usually located adjacent to an oil refinery to minimizetransportation costs for the feedstocks produced by the refinery. Specialty chemical plants are usually much smaller and not as sensitive to location. A process is a naturally occurring or designed sequence of operations or events, possibly taking up time, space, expertise or other resource, which produces some outcome. ... A factory (previously manufactory) is a large industrial building where goods or products are manufactured. ... A chemical substance is any material substance used in or obtained by a process in chemistry: A chemical compound is a substance consisting of two or more chemical elements that are chemically combined in fixed proportions. ... A petrochemical is any chemical derived from fossil fuel. ... View of the Shell/Valero Martinez oil refinery An oil refinery is an industrial process plant where crude oil is processed and refined into useful petroleum products. ... In mathematics, optimization is the discipline which is concerned with finding the maxima and minima of functions, possibly subject to constraints. ... A feedstock is petrochemical used as a raw material to be fed into a machine or processing plant. ...
Several proposals to require all major chemical facilities to improve their security are pending in the Republican-controlled Congress, where similar bills have died in each session since Sept. 11, amid heavy resistance to imposing new regulations on the industry.
Chemicalplant owners themselves, he said, should be left to make decisions about how to secure their own facilities, so long as their plans meet the government's performance standard.
And under no circumstances, Chertoff said, should plant owners be told they must switch to inherently safer chemicals in their manufacturing process -- even if doing so would eliminate the risks to surrounding residential areas and come at little or no extra cost to the company.
Chemical manufacturing is divided into seven segments, six of which are covered here: Basic chemicals; synthetic materials, including resin, synthetic rubber, and artificial and synthetic fibers and filaments; agricultural chemicals, including pesticides, fertilizer, and other agricultural chemicals; paint, coating, and adhesives; cleaning preparations, including soap, cleaning compounds, and toilet preparations; and other chemical products.
From chemical ingredient ratios to chemical reaction rates, the operator is responsible for the efficient operation of the chemicalplant.
Chemical companies are finding that, in order to remain competitive, they must differentiate their products and produce specialty chemicals, such as advanced polymers and plastics designed for customer-specific usesfor example, a durable body panel on an automobile.
