Acid Rain

Introduction
Acid rain has become an environmental concern of global importance within the last decade. With the increasing environmental awareness of the "unhealthy" condition of our planet earth the concern about acid rain has not lessened.
In brief, acid rain is rain with pH values of less than 5.6. When dealing with acid rain one must study and understand the process of making Sulfuric acid. In this project we will take an in depth look into the production of sulfuric acid, some of its uses and the effects of it as a pollutant in our environment.
Sulfuric Acid Industry in Ontario
Among the many plants in Ontario where sulfuric acid is produced, there are three major plant locations that should be noted on account of their greater size. These are:
- Inco. - Sudbury
- Noranda Mines Ltd. - Welland
- Sulfide - Ontario
There are a number of factors which govern the location of each manufacturing plant. Some of these factors that have to be considered when deciding the location of a Sulfuric Acid plant are:
a. Whether there is ready access to raw materials;
b. Whether the location is close to major transportation routes;
c. Whether there is a suitable work force in the area for plant construction and operation;
d. Whether there is sufficient energy resources readily available;
e. Whether or not the chemical plant can carry out its operation without any unacceptable damage to the environment.
Listed above are the basic deciding factors that govern the location of a plant. The following will explain in greater detail why these factors should be considered.
1) Raw Materials The plant needs to be close to the raw materials that are involved in the production of sulfuric acid such as sulfur, lead, copper, zinc sulfides, etc..
2) Transportation A manufacturer must consider proximity to transpor-tation routes and the location of both the source of raw materials and the market for the product. The raw materials have to be transported to the plant, and the final product must be transported to the customer or distributor. Economic pros and cons must also be thought about. For example, must sulfuric plants are located near the market because it costs more to transport sulfuric acid than the main raw materials, sulfur. Elaborate commission proof container are required for the transportation of sulfuric acid while sulfur can be much more easily transported by truck or railway car.
3) Human Resources For a sulfuric acid plant to operate, a large work force...
