Introduction

All chemical processes require land for chemical storage, process equipment, and labor facilities.

Geographical selection

The location surrounding a chemical plant can substantially influence its construction costs and operating costs, and may affect long-term profitability. Thus it is important to choose an appropriate location for every facility.

Factors considered

Natural resources

Proximity to continental and underwater oil deposits, natural gas, coal mines, and other resources.

Weather

Its influence on ambient temperature and thus on utility cost.^{[ citation needed ]} Also rain and humidity, and the sensitivity of the process to water exposure.

Proximity to related chemical operations

Oil rigs are found in the gulf, and oil refineries on its shore. Biofuel production plants are found in the midwest.^{[ citation needed ]}

Laws and regulations

Some states are more friendly to chemical engineering operations, or may impose additional regulations. Property costs, property taxes, corporate income taxes, and environmental contamination fines will vary between states.

Waste Minimization and Management

Waste Minimization

Production of waste is arises naturally in any plant and require a noticeable amount of resources to take care of. Before even considering methods of managing ways, cost can significantly be reduced by efficient management by source reduction. Below are some source reduction strategies which can be employed:

1. Purification of feeds.

2. Protect catalysis and adsorbents.

3. Eliminate use of extraneous materials.

4. Increase recovery from separations.

5. Improve fuel quality.

Cost

All of the above criteria ultimately influence the capital and operating costs of a plant, and its expected lifespan.

$TC=rK+wL$

Local wages, prices of chemical feedstock, shipping costs, and utilities all contribute to total operating costs.

Property prices, rental fees, taxes, and existing company property in the area contribute to recurring investment costs.

Common locations

There are many common locations for chemical processes, often specific to one or more industries.
