IntroductionSince the 1930s, the design and construction of chemical plants have become

increasingly specialized.

Chemistsand engineerscollaborate to develop process and engineering

concepts, which engineersand designersthen transform into detailed plans

and specifications for all the components of a chemical plant.

Purchasing agentsprocure equipment from specialist manufacturers.

Construction and installation firmsare put under contract to build the plant.

IntroductionPlant design and construction starts as an idea of the potential owner.

Increasingly complex markets and the interrelations of the world economic and

political systems require critical examination of every project for feasibility,

economic relevance, and environmental impact.

As a rule, this is done with the aid of a feasibility studythat includes preliminary

design work.

Market analysesare carried out to determine potential sales, future demand

dynamics, availability of raw materials, and the competitive situation.The plant capacityand locationare specified.

Particular attention must be paid to environmental protection.

Studies are supplemented by sufficiently accurate estimates of capital

requirements and profitability.

IntroductionOnce the decision has been made to go ahead with the construction project,

whereby the owner may have opted not to carry it out himself, the owner will

prepare an accurate, comprehensive definition of the plant which is used as

the basis for inviting bids from competent engineering contractors.

This approach is increasingly employed, especially for large projects.

If the owner has an adequate pool of experienced design engineers, construction

specialists, and procurement staff, he may plan and construct the plant himself.

The conceptual phase of the project ends when an appropriate engineeringfirm is chosen and the contract signed.

IntroductionThe implementation phaseconsists of the engineering of the chemical plant,

procurement of plant equipment and material, construction, and commissioning.

The engineering contractor either performs all of these tasks or brings in

subcontractors or personnelemployed by the owner to carry out a portion of

the work.

Plant equipment is fabricated by specialized manufacturers.

Only in rare cases does the engineering contractor or the plant owner have

production facilities.
