It is a substance that can undergo extremely rapid, self-propagating decomposition with the formation of large volumes of gaseous products and evolution of heat. It is generally prepared in solid form.

It is a generic name for powdered materials which have plastic flow when mixed with water or other liquid, but form a solid structure in several hours with varying degrees of strength and bonding properties which continue to improve with age.

The process consists of condensing chloral and chlorobenzene using strong sulphuric acid (100%) or oleum as a catalyst. The reaction takes place at 15-30°C for 5-6 hours. The spent acid is then withdrawn, and the organic layer is water-washed and neutralised with soda-ash. The products are then dried and distilled for chlorobenzene removal and recycling

It is defined as the treatment of hydrocarbons at high temperatures to change their molecular weights. The principal purpose is to crack molecules, however larger molecules are also produced simultaneously

This process of urea production uses mineral oil as a carrier for temperature control and to minimize corrosion problems.

It is a system consisting of two or more pulleys (sometimes referred to as drums), with a closed loop of carrying medium rotating about them. It is an endless belt suitably supported and driven, which transports solids from place to place.

It is a barrier made of connected strands of metal, fibre, or other flexible or ductile material. It is similar to a web or a net in that it has many attached or woven strands. It is defined as the number of openings per linear inch of screen surface.

The ratio of the surface energy created by crushing to the energy absorbed by a solid for a given machine and material.

This device is meant for the separation of two immiscible liquids of different densities. The feed mixture enters at one end of the separator, flows slowly through the vessel, separates into two layers, and discharges through overflow lines.

In sedimentation, this dimensionless number compares the gravitational force acting on a particle to the viscous force resisting its motion and is commonly used to characterize the settling regime of particles.

It is the energy emitted by matter in the form of electromagnetic waves (or photons) because of the changes in the electronic configurations of the atoms or molecules.

When two bodies at different temperatures are brought into contact, heat transfer occurs until both bodies assume the same temperature at the point of contact. Therefore, a fluid and a solid surface will have the same temperature at the point of contact.

The ratio of convective to conductive heat transfer across a boundary. The convection and conduction heat flows are parallel to each other and to the surface normal of the boundary surface and are all perpendicular to the mean fluid flow in the simple case.

It is a relationship between the friction factor and the Reynolds number, pipe roughness, and inside diameter of pipe.

It is a dimensionless number in fluid dynamics and heat transfer which approximates the ratio of the buoyancy to viscous force acting on a fluid. It frequently arises in the study of situations involving natural convection and is analogous to the Reynolds number.

It is a relative logarithmic scale used to compare the intensities of two sounds.

The process by which the results of a risk analysis are used to make decisions, either through a relative ranking of risk reduction strategies or through comparison with risk targets.

Any abnormal condition or disorder, other than one resulting from exposure to environmental factors associated with employment.

The average number of fatalities expected in a particular worker population of interest over a period of 108 worker hours (roughly 1,000 employees working lifetimes).

It is the hazard modeling program which is used widely to plan for and respond to chemical emergencies. It can model toxic gas clouds, flammable gas clouds, BLEVEs (Boiling Liquid Expanding Vapor Explosions), jet fires, pool fires, and vapor cloud explosions
