Week 2 Flashcards
is a method of altering a compound. _______________ is
done to change the chemical structure of raw (bulk) materials in order to obtain
products that are valuable to other industries/daily life.
Chemical processing
is defined as a process that does not involve any
chemical reactions.
A unit operation
involves a chemical reaction resulting in the
transformation of substances into new chemical compounds.
unit process
is someone who designs, implements, and
optimizes production processes to improve safety, efficiency, and
cost-effectiveness.
CHEMICAL PROCESS ENGINEER
are tasked with managing the
processing operations throughout the chemical processing
facility. These individuals must monitor panel lights,
recording instruments, and flow meters.
Chemical process operators
are the visual way to show how a process is intended to run, the
connections between the various unit operations and processes, and the
connections with raw material and utility supplies.
Flow sheets
is normally not used for a particular unit but is used to
represent a chemical complex where each process unit is represented as a block.
A Block Flow Diagram (BFD)
Such diagram is read in conjunction with the process
description and in addition contains stream details which are linked to the
heat and material balance of the process.
A Process Flow Diagram
is a diagrammatic representation of the distribution of utilities to
various consumers in a process plant. It is typically prepared to cover the
following utility hook-ups
Utility P&ID
is a PFD in which the
various sections of the plant are marked showing the specified
materials of construction.

.
Mass transfer:
Distillation, evaporation, crystallization, leaching,
absorption, adsorption, extraction, etc
are devices that are used
to increase the static pressure of
liquids by converting mechanical
energy to a high-pressure liquid
flow.
Pumps
is the unit operation
by which fine solids are
transformed into a fluid-like state
through contact with a gas.
Fluidization
are equipment used to
homogenize media inside a tank.
Agitators
are designed to rapidly blend
two or more components together,
regardless of whether they are of the
same or different phases (e.g., solid-
liquid, liquid-liquid, gas-liquid).
Mixers
is a unit operation
that separates a liquid from solids
by means of heat transfer via
vaporization or boiling.
Evaporation
is a process equipment where in chemicals are
fed in order to make them chemically react with each other for the
purpose of making a desired product.
chemical reactor
is a closed vessel
in which reactions happen and it is
a non-continuous type of reactor.
The reactants are fed in to the
reactor all at once initially.
batch reactor
