Chemical Process Safety
This Federal Agency is charged with enforcement of safety and health legislation
What is OSHA (Occupational Safety and Health Administration)?
Input – Output = this
What is accumulation?
These are the three fundamental mechanisms of heat transfer.
What are conduction, convection, and radiation?
This separation technique accounts for 90-95% of all separations in the chemical process industry.
What is Distillation?
This equation used to calculate the fanning friction factor for laminar flow.
What is 16/Re?
Device that limits the pressure increase in a system or vessel
What is a relief valve?
Enthalpy change required for a solid to become a liquid at a specific temperature and pressure
What is the latent heat of fusion?
This type of temperature difference is commonly used in heat exchanger design.
What is the log-mean temperature difference?
Method used to separate solids from fluids by interposing a medium through which only the fluid can pass.
What is filtration?
A pump characterized by approximately constant head, but with flowrates that increase or decrease depending on the system resistance.
What is a centrifugal pump?
The 3 sides of the fire triangle.
What are oxidizer, fuel and ignition source?
When a vapor is cooled slowly at constant pressure, this is the temperature at which the first liquid droplet forms.
What is the dew-point temperature?
The dimensionless ratio of convective heat transfer to conductive heat transfer.
What is the Nusselt number?
A simplified version of this separation process is seen in a coffee or tea maker
What is Leaching?
Equation used to determine the pressure drop across a packed bed.
What is the Ergun equation?
This is the temperature above which adequate energy is available in the environment to provide an ignition source
What is the Autoignition Temperature (AIT)?
This chart contains the web-bulb temperature, dry-bulb temperature, relative humidity and other parameters.
What is a psychrometric chart? or What is a humidity chart?
A physical constant used in radiation heat transfer calculations, with dimensions of power per area per temperature raised to the 4th power
What is the Stefan-Boltzmann constant?
The amount of condensed distillate returned to the top of a distillation column, relative to the amount removed as a product.
What is the reflux ratio?
A situation where the drag force on a falling object is balanced by the gravity and buoyant forces.
What is terminal velocity?
These are the 4 major methods for achieving Inherently Safer Design
What are minimize, substitute, moderate and simplify?
The process of contacting a stream of warm gas with a stream of cold liquid that results in gas cooling and liquid evaporation
What is adiabatic cooling?
Assumption made when the Biot Number is less than 0.1.
What is the lumped solution assumption? (Uniform temperature throughout body during transient heat transfer).
A relationship between adsorbed and non-adsorbed solute in which the adsorbent may become completely saturated.
What is a Langmuir isotherm?
The assumption that the fluid velocity at a stationary surface is equal to zero is called this.
What is the no slip condition?
