Question

Answer the following questions using the report on Amines worst case studies: Worst Case Studies on Amine Emissions from CO, Capture Plants 1. What is the purpose of capturing CO 2 in the environment? Write one technology that is used to capture CO2, which mentioned in this report. 2. Describe the environmental impact of Nitrogen emission? 3. Write three atmospheric degradation products from amines. 4. Write two types of amine deposition mechanisms. 5. Describe the health impact of nitramines and nitrosamines when they expose to the environment.

Answer 1

Ans :

1) The purpose of capturing CO2 in the environment is to reduce global warming.

The leading technology for CO2 capture is through the use of amines.

2) Nitrogen load to ecosystem above the critical load lead to eutrophication. The exceedance of a critical load may result in increased biomass production and reduced plant diversity (decline of lichens, mosses and evergreen shrubs).

3) (i) Amides

(ii) Nitrosamines

(iii) Nitramines

4) Deposition can be divided into two main mechanisms

(i) Dry deposition

(ii) Wet scavenging by rainfall

5) Health impact of nitramines and nitrosamines

a) Toxic for freshwater acquatic organisms.

b) Threaten drinking water quality.

c) Leads to Eutrophication

d) Air pollution

e) Human Carcinogens( causes cancer)
