Expert Answer:CHE462 ASU Alternative Method for Carbon Capture M

  

Solved by verified expert:I need you to write a report of 2-3 pages regarding carbon dioxide engineering process. I attached 4 files which are: the project, progress memo regarding my section in the project, an example of the report how it looks like, and the instructions of how to write a report. look at them carefully please!! carbon dioxide engineering process. This process has energy intensive steps that probably will not make the best alternative to design in detail. I need you to show and explore other alternatives of CO2 disposal. remember the goal of this process is to minimize carbon dioxide capture cost. the cost includes utilities and amortized capital values. my part of the project is to show Carbon Engineering Ltd has developed a process for extracting carbon dioxide from air by using CO2 disposal, so you need to select other alternative than co2 disposal for CO2 capture cost and justify why it was considered to be the best alternative and has less cost than the co2 disposal. read the file of the project carefully!!!!
**pleases use the same references in the memo and you
can add more from reliable sources from the internet please.
-No plagiarism please!!!

PROJECT 2 – team effort
Atmospheric Very Efficient Cleaners Inc (AVEC)
TO: CHE 462 WORLD CLASS EXEMPLARY DESIGN ENGINEERS
FROM: J.R.Boss, Chair & CEO AVEC Inc
DATE: 2/4/19
SUBJECT: DESIGN FOR CO2 REDUCTION FROM ATMOSPHERIC AIR
In 1997 an international meeting was held in Kyoto, Japan, 2012 in Doha, Bahrain and
lately in Paris (the Paris Accord) to discuss the Global Warming trends and remediation
policies to curb carbon dioxide emissions. AVEC Inc wants to join with (avec) the Paris
Accord spirit. The climate change in global rising temperatures shifted weather patterns
throughout the world. Currently, there have been articles urging the removal of 410ppm
carbon dioxide from atmospheric air.
As an example, Carbon Engineering Ltd has developed a process for extracting carbon
dioxide from air by using an air contactor, pellet reactor, calciner, slaker and CO2
disposal. Estimated removal costs range from $100 to $250/ tonne by company
estimators.
You will interact with your group but work alone on your section of the project to
explore the business venture details to be proposed by AVEC Inc which will reduce the
amount of carbon dioxide from atmospheric air. The project objective is to minimize
total carbon capture cost per ton (or tonne). Use a money borrowing rate of 6% with
an equipment life of 20 years. The team combined effort will assure AVEC Inc of
multitude design outcomes for proposal consideration.
Your final design report must be on my desk (aka Canvas) by 9:40 AM Monday
April 1, 2019. Also, there will be progress reports due on Monday February 11 and
on Monday March 18 so as to help assure a strong steady pace of your dedicated
participation.

DATE: 3/18/19
SUBJECT: Alternative that minimizes CO2 capture cost during CO2 disposal
The alternative of CO2 capture cost is the use of electro-reduction of carbon dioxide (ERC).
The objective of ERC is taking CO2 from industries and then converting it to formic acid
and formate salts (Dominguez-Ramos et al., 2015). The two byproducts get reused for
industrial applications. The use of formic acid also offers a crucial role for doing fuel cell
development, whereby it is used as direct fuel and as a fuel storage material for hydrogen
when it is released on-demand. With a capability of providing net revenue per CO2
replaced, the use of ERC method compared to carbon capture method offers a positive
return on investment. Estimates show that the cost of removing one tonne of CO2 from the
atmosphere is about $200. The method is used in the initial collection of industrially
produced carbon. According to Williams (2018), it is less costly than the CO2 disposal
because recycling of industrial CO2 offers a range of biofuels such algal being attained
through biochemical conversion, methanol from CO2 from thermochemical conversion,
and through solar photocatalytic conversion to get biocatalytic fuel. All these methods
seek to offer business opportunities for people and huge carbon reduction from the
atmosphere. In the end, allowing the saving of the world from global warming and job
opportunities, and thus reducing unemployment. Being a risky solution for carbon
reduction, carbon capture storage is also expensive not like ERC which offers a cheap and
return on invest solution since it provides by-products that are used as fuel.

MEMORANDUM

TO: Professor Reader
FROM: Researcher
DATE:1/25/2019
SUBJECT: Crystallization Experiment
( note: the first paragraph is the abstract) The crystallization nucleation kinetic
parameter, i, for potassium chloride in a 37 C cooling crystallizer was (found to be) 2.3.
The kinetic parameter, i, was 35% higher than literature values. The higher kinetic
parameter value was due to fluctuations in the feed flow rate controller and the low
number of data runs (four). To achieve agreement within 10% of the kinetic parameter
theoretical value, a new flow control valve was recommended and more runs of at least
10 would be needed. (note: briefly give final analysis, reasons, conclusions and
recommendations)
(note: The body of the memo supports the first paragraph with tables, figures and
reasons. Normally, there is little coverage in theory development and only major
effects are briefly discussed. Support only those claims made in the first paragraph.)
Figure 1 is the plot of the log of nucleation density versus log of growth rate for each
steady state experiment. The best line fit revealed random scatter not biased offset data
error. The data scatter was caused by the corroded feed flow control valve.

Control valve was junk (do not say it like this, be professional). Replace the
control valve with a non-corrosive valve for future investigations.

More data runs would be needed to improve the kinetic parameter estimate. (be
specific, say 10 runs based on a Student T test analysis)

In this experiment, we found that the relative
volatility is close to the theoretical one. It was
partially boiled by steam and it changed. Figure 5
and Table 3 show all of the runs.
VLE ABSTRACT
The relative volatility of ethyl benzene and
styrene at 3 bar and 130C was 1.25 which was 5%
higher than assuming an ideal solution. The feed
quality ranged from 10% to 35%.
