Course 5 LNG Thermodynamics Part 3A 2 PDH
TEXAS COMPLIANCE PENDING:
Texas requires a class be reviewed by enough students to assign earned CPE credits. This course is still new enough that we are obtaining the reviews needed. We recommend Texas CPAs check back soon. This process is usually finished within a few weeks.
This course introduces learners to Liquefied Natural Gas (LNG) production processes. LNG is widely used around the world. It is a very compact form of natural gas in liquid form. It is used on very cold days to supplement gas from the interstate pipelines to supply gas load centers like New York, Boston, and other major load areas. Natural gas (essentially the same as vaporized LNG) is the cleanest burning fossil fuel as it contains the least amount of carbon of all the fossil fuels. Thus, many electric power plants now use natural gas or are converting from dirtier fossil fuels to the use of natural gas or vaporized LNG. Upon completion of this course, the learner should, at a high level, be able to understand:
- The methods of pretreating natural gas before liquefaction
- Removal of solids and liquids from the liquefaction feed gas
- Removal of H2S and CO2 from the liquefaction feed gas
- Removal of mercury from the liquefaction feed gas
- Removal of water vapor from the liquefaction feed gas
- Removal of heavy hydrocarbons from the liquefaction feed gas
- How a car air conditioner works
- Refrigerants
- Limitation of single component refrigerants
- Getting down to cryogenic temperatures
- Cascade systems
- Mixed refrigerant systems
- Separated mixed refrigerant systems
- Propane precooled mixed separated mixed refrigerant systems
- Post-production nitrogen removal process
- Joules Thompson processes
- Efficiency improvements of liquefaction systems
- The basics of thermodynamics
- The thermodynamics of refrigeration systems
- simple air conditioning as an automobile air conditioning system
- The thermodynamics of liquefying natural gas
- Cascade systems (in series single refrigerant systems)
- Mixed refrigerant systems
- Cascaded single and mixed refrigerant systems (C3MR system)
- Cascaded mixed refrigerant systems
