Polymer chemists study
large, complex molecules that are built up from many smaller units. They study
how the monomers combine, and create useful materials with specific
characteristics by manipulating the molecular structure of the
monomers/polymers used, the composition of the monomer/polymer combinations, to a large extent, affect
the properties of the final product by applying chemical and processing
techniques.
Chemicals:
The chemical industry is
crucial to modern world economies, and works to convert raw materials such as
oil, natural gas, air, water, metals, and minerals into more than 80,000
different products. To make consumer products, as well as in the manufacturing,
service, construction, agriculture, and other industries those base products
are used. Majority of the chemical industry’s output is polymers and polymer-related, including
elastomers, fibers, plastics, adhesives, coatings, and more. Rubber and plastic
products, textiles, apparel, petroleum refining, pulp and paper, and primary metals are the major industries
served.
Oil & Gas
The entire oil and gas
industry chain, from upstream oil and gas production activities, to midstream, and finally downstream refinery production of fuels, uses the polymeric materials only. Solid-state
polymers such as plastics, fibers, and elastomers for use in oil well sites and
off-shore platforms, with applications including construction of structures
such as pipelines, propellants in hydraulic fracturing, and as coatings. Polymeric additives are used in upstream oil production applications as well stimulants, drilling
fluids, corrosion inhibitors, scaling inhibitors, and viscosity modifiers. They
are even used as components of cements used in protecting casings down hole.
In downstream operations,
polymeric additives are used to overcome operational issues in the refinery, distribution
systems, and storage tanks and in different fuel transport and combustion
applications. Finally to improve performance features. To resolve specific
issues at a refinery, polymers may be used as stand-alone products, and combined
with other products to create a multi-functional package for use in finished
fuels for the automotive industry. Some specific examples of polymeric
additives used in downstream applications include synthetic base stocks for
lubricants, pipeline drag reducers, cold flow improvers, demulsifiers, deposit
control additives, dispersants, friction modifiers, corrosion inhibitors,
antifoamants, and viscosity improvers.
