Term | Definition |
---|---|
absolute pressure | pressure relative to a vacuum |
aneriod gauge | type of gauge that uses a small bellows that changes shape as pressure changes |
bimetallic temperature measurement device | device that relies on the concept that different metals expand and contract due to temperature at different rates |
block flow diagram | extremely basic representation of major processes in a plant |
change-of-state temperature measurement device | device that permanently changes colors when it reaches a certain temperature |
chemistry | scientific study of materials, their properties, their interactions,and the changes that they undergo |
coal gasification | clean coal method in which coal is broken down into its basic chemical parts using heat and pressure with steam |
deformulation | process that involves the identification and separation of chemical components within a substance |
differential pressure flow meter | type of flowmeter that constricts the flow by placing some sort of obstruction inside of a pipe or by narrowing the pipe at a point |
first law of thermodynamics | application of the law of conservation of energy |
fluid flow | liquids or gases in motion |
gauge pressure | measurement of pressure relative to the atmosphere pressure |
infrared temperature measurement device | device that measures the thermal radiation emitted from a material |
laminar flow | type of flow that has no disruption between the layers of the moving fluid, with no eddies or changes |
mass balance | property founded in the law of the conservation of matter |
mechanical flow meter | type of flowmeter that uses a variety of mechanical devices inside of a pipe to measure flow |
open-channel flow meter | type of flowmeter that measures the flow in a channel rather than in a pipe |
plant layout | arrangement of facilities based on the location of he materials that will be made into products and how they are moved through the plant |
process flow diagram | detailed diagram that includes main flow of chemicals |
"right to understand" laws | laws that are designed to ensure people know what chemicals that are being exposed to and what the health effects could be |
second law of thermodynamics | often called the entropy law, this law is concerned with the idea that concentrated source of energy with naturally disperse |
surface tension | characteristics almost like a film on the surface, caused by the molecules of a liquid tending to be more attracted to each other |
thermodynamics | study of work, energy, and efficiency in large-scale systems |
velocity flow meter | type of flowmeter that measures the speed of passing fluid and the depth of the fluid |
waste | by-product of chemical operations |
