c) It contains a higher percentage of heavier hydrocarbons like ethane and propane.
2. What is the primary advantage of using Rich Gas?
a) It is easier to transport. b) It has a lower cost per unit of energy. c) It burns cleaner than standard natural gas. d) It has a higher heating value, providing more energy per unit of volume.
d) It has a higher heating value, providing more energy per unit of volume.
3. Which of the following is NOT a potential application of Rich Gas?
a) Power generation in power plants. b) Production of plastics and other chemicals. c) Fuel for residential heating systems. d) Fuel for vehicles.
c) Fuel for residential heating systems.
4. What is a potential drawback of using Rich Gas?
a) It is highly flammable and requires specialized handling. b) It is not compatible with existing natural gas infrastructure. c) The cost of producing Rich Gas can be higher than standard natural gas. d) It emits more greenhouse gases than standard natural gas.
c) The cost of producing Rich Gas can be higher than standard natural gas.
5. Which statement best describes the future of Rich Gas?
a) It is expected to become less important as renewable energy sources increase. b) It is likely to play a growing role in meeting global energy needs due to its efficiency and versatility. c) It is facing significant regulatory challenges that may limit its widespread adoption. d) It is a niche fuel source with limited potential for growth.
b) It is likely to play a growing role in meeting global energy needs due to its efficiency and versatility.
Scenario: A power plant is considering switching from standard natural gas to Rich Gas to increase its energy efficiency.
Task:
**Research:** * **Standard Natural Gas:** Typical HHV is around 39 MJ/m³ (1,050 Btu/ft³). * **Rich Gas:** Typical HHV is around 45-55 MJ/m³ (1,200-1,450 Btu/ft³). **Calculation:** * Assuming an HHV of 50 MJ/m³ for Rich Gas, the percentage increase in energy output is: * ((50 MJ/m³ - 39 MJ/m³) / 39 MJ/m³) x 100% = **28.2%** **Potential Challenges:** * **Cost:** The cost of Rich Gas may be higher than standard natural gas. * **Infrastructure:** The power plant may need to adjust its equipment or pipelines to handle the higher energy content and potential variations in composition of Rich Gas. * **Availability:** Consistent supply of Rich Gas in the desired quantity and quality may need to be secured.
