Many refineries must change their facilities and processes to meet this need. Environmental Concerns New antipollution equipment is needed in some refineries to control emissions and produce non-polluting products. The type of crude oil being processed determines the amount of each product obtained from each barrel. Transportation And Distribution Huge quantities of crude oil and refined products are moved and distributed all over the world every day. Tankers carry up to half a million tons of oil.
Trucks can reach otherwise inaccessible areas with small loads of oils and gas.
Barges use inland water to move oil cheaply from producers to consumers. Pipelines move oil long distances by pumping. This is the most economical way to move oil products. Trains and tank cars carry heavy, corrosive and temperature-sensitive products. Destinations include refineries, service stations, factories, airports, public utilities, etc.-wherever oil products are needed.
