N
Nitrogen Rejection Process for Natural Gas
A Nitrogen Rejection Unit is used to remove nitrogen from natural gas to increase the heating value of the gas. This process involved cryogenic distillation.
M
Mercury Removal from Natural Gas
This process uses solid adsorbents that remove mercury from gas to produce residuals in the range of 0.01–0.001 µg/Nm3. Calgon sulfur impregnated HGR®
U

Z
Zeolite, its types, the working principle, and operations
A zeolite is a naturally occurring microporous crystalline material based on silicon and aluminum that can b modified to be used in an ion exchange bed.
R
Refinery Process, step-wise operation, and their simulation
Crude oil is first processed to remove the water, inorganic salts, suspended solids, and water-soluble trace metals. There are two ways of desalting.
