Carbon capture technology and five major production sectors that contribute in environmental pollution

 What is carbon capture technology?

Carbon capture technology is a process that captures carbon dioxide (CO2) emissions from power plants, industrial facilities, and other sources, before they are released into the atmosphere. The captured CO2 can then be stored in underground reservoirs, used in industrial processes, or converted into useful products like fuel or building materials.

-> Examples:

-> Century plant:



The greatest CCS plant in the world is the Century petroleum gas handling facility in West Texas, owned by Occidental Oil. In 2008, Sandridge Energy and Occidental Oil agreed to set up and staff the Century CCS office. The plant, which cost over 1.1 billion dollars to build, captures CO2 for Occidental's improved oil recovery (EOR) projects in the Permian Bowl. The CO2 catching plant, which is located in Pecos District, began operations in November 2010 by charging its most iconic train. This train has a plan limit of 5 million tones of CO2 capture annually. In late 2012, a new CO2 limit of 3.4 million tones per year was imposed on the following train. A 160 kilometer pipeline transports the CO2 collected by the office to a contemporary central point located in Denver City.

-> Shute creek gas processing plant:


The Shute Spring gas processing facility is located in Wyoming, United States, and is owned by ExxonMobil. Around 365 million cubic feet of CO2 are captured daily by the CCS facility operating nearby LaBarge, Lincoln Region, which is equivalent to taking more than 1.5 million automobiles off the road. The CO2 captured by the pre-burning method used by the Shute Rivulet gas handling plant is applied to better oil recovery operations in various Wyoming oil fields. CO2 is transported through pipes from Exxon, Anadarko, and ChevronTexaco out of the Shute River CCS office. The volatile gas streams produced from the LaBarge gas well and other fields in Wyoming are the source of CO2 that the facility captures. The LaBarge handling facility separates the CO2 from several components. To equip the office with the Controlled Freeze Zone (CFZ) catch innovation it developed, ExxonMobil completed an 86 million USD addition at the Shute Stream gas processing plant in 2010. The CO2 is frozen out and then softened using CFZ's single-step cryogenic division process, which also gets rid of methane, hydrogen sulphide, and other components found in harsh gas resources.

-> Methods:
There are several different methods for capturing CO2, including: 

-> Pre-combustion capture:
This method involves capturing CO2 before fossil fuels are burned. The fuel is reacted with oxygen or steam to produce a gas mixture containing CO2, which can then be separated and captured.

-> Post-combustion capture:
This method involves capturing CO2 after it has been emitted from the burning of fossil fuels. The CO2 is separated from other gases using chemicals or physical processes. 

-> Oxy-fuel combustion:
This method involves burning fossil fuels in a mixture of oxygen and recycled flue gas, which produces a flue gas containing mostly CO2 and water vapor. The CO2 can then be easily separated and captured.

-> Direct air capture:
This method involves capturing CO2 directly from the air using chemical or physical processes. 

-> Carbon sequestration:
This method involves storing carbon dioxide underground in geologic formations, such as depleted oil and gas reservoirs or saline aquifers. The carbon dioxide is injected into these formations, where it is expected to remain for hundreds or thousands of years. 

-> Carbon capture and utilization(CCU):
This method involves capturing carbon dioxide and using it as a feedstocks for the production of chemicals, fuels, and other products.

                                                Tuesday, October 18, 2022

                                                what is 3D printing? Give some examples. How does 3D printing work? Types of 3D printing.

                                                 what is 3D printing?

                                                3D printing:

                                                Building a three-dimensional product from a CAD model or digital 3D model is known as 3D printing or additive manufacturing. It can be done via a variety of methods in which material is placed together (usually layer by layer), connected, or solidified under computer control (for example, fusing plastics, liquids, or powder grains).Rapid prototyping was a better phrase to use at the time to describe 3D printing techniques, which were thought to be only adequate for the manufacture of functional or aesthetically pleasing prototypes. The phrase "additive manufacturing" can now be used to refer to some 3D printing techniques because of the enhanced accuracy, repeatability, and material variety that have been achieved as of 2019.



                                                Examples of 3D printer:

                                                3D pen:

                                                A 3D pen is a pen with a nozzle that extrudes heated or warm plastic. No software is required. There are no files to transmit, nor is there complicated technology to learn. Whatever you envision, you can draw, in the words of a teacher with whom we collaborate. Right there, it passes from your brain to your hand.

                                                 

                                                3D Human Model:

                                                Mechanical engineers and designers can optimize the physical human-product interaction by using the 3D HUMAN MODEL. The models make it simpler to use the data in a 3D CAD environment and give a wonderful perspective of the statistical 1D data.





                                                Prosthetics:
                                                    Through 3D printing, you may scan a person's body and then print a customized model that fits the specific geometry of their body. A company by the name of print myleik even offers open source prosthetics design plans. They enable others to design ornamental prosthetic leg components that they can use to express their unique personality.




                                                3D shoes:
                                                With 3D printing technology, Nike is dominating. Recently, the business debuted fly print, a 3D-printed textile upper for shoes. It's the first of its kind and might set a new benchmark for performance running shoes because the prototypes can be made 16 times faster than with conventional shoe manufacturing methods and the shoes can be quickly altered and produced for particular sports or specific athletes.




                                                How 3D printer works?

                                                One of the most innovative technologies of the twenty-first century is 3D printing, however you might not be aware that there are numerous 3D printing methods available. Let's discuss the four most popular types:
                                                • FDM:
                                                Fusion deposition modelling is known as FDM. Most likely, the 3D printer you saw in a person was an FTM printer, so explain how it operates. The FTM printer functions similarly to a hot glue gun, with a solid substance called filament going into one end and passing through a hot nozzle where it melts and is then deposited in tiny layers. To put it another way, FDM 3D printing is essentially just 2D printing done repeatedly with the exception that every time a layer is finished, the nozzle moves up a tiny bit and the subsequent layer is printed on top of it.


                                                • SLA:
                                                SLA essentially grows objects out of a glue puddle using light. UV light is shone into a pool of photoreactive resin using SLA machines, and any resin hit by the light hardens and makes a layer of the object. In general, these printers have the ability to produce significantly more detailed items than FDM.




                                                • Laser Center:
                                                LS printing involves flashing a high power laser over a bed of extremely fine powder, fusing the particles to form a thin solidified layer. The machine then sweeps more powder over that layer and repeats the process until the 3D object is finished. This process is uncommon in consumer-level 3D printers, but it is frequently used in the industrial sector to produce large, durable objects made of metal. SpaceX employed this technique to 3D print its super-durable rocket engine, which is undoubtedly difficult to fault.

                                                • polyjet:
                                                Consider the fact that this one combines SLA and FDM. The advantage of this method is that it is incredibly quick and precise. Polyjet machines squirt out tiny droplets of photoreactive resin on to a build surface and then immediately harden the resin with ultraviolet lights. This process is then repeated hundreds of times to create objects from the bottom up. Unfortunately, the majority of polyjet printers are thousands of dollars expensive.




                                                Types of 3D Printing:
                                                According to ISO/ASTM 52900 additive manufacturing - general concepts - nomenclature, 3D printing methods, usually referred to as additive manufacturing, are divided into seven classes. All 3D printing techniques fit under one of the following categories:

                                                Binder Jetting:
                                                Binder jetting involves the application of a small layer of powered material, such as metal, polymer sand, or ceramic, onto the build platform. Next, print heads apply drops of glue to bind the material's particles together. Layer by layer, the part is constructed using this method, and afterward, post-processing may be required to complete the build. Metal pieces can be thermally sintered or penetrated with a metal that has a low melting point, like bronze, as examples of post processing, while ceramic or full-color polymer parts can be saturated with cyanoacrylate adhesive.

                                                Direct Energy Deposition:

                                                In direct energy deposition, wire or powder feedstock is fused as it is deposited using focused thermal energy such as an electric arc, laser, or electron beam. To build a layer, the procedure is traversed horizontally, and to build a portion, layers are piled vertically.


                                                Material Extrusion:

                                                A spool of filament is fed into an extrusion head with a heated nozzle in the process of material extrusion, also known as fused deposition modelling (FDM). The build platform then lowers in preparation for the subsequent layer after the extrusion head heats, softens, and deposits the heated material at predetermined positions.
                                                Short lead times and cost-effectiveness come at a cost of low dimensional accuracy and frequent post-processing to achieve a smooth finish. Additionally, this method often results in anisotropic parts, which are weaker in one direction and unsuitable for demanding applications.


                                                Comparable to inkjet printing, material jetting involves depositing layers of liquid material from one or more print heads rather than ink on a page. The layers are then allowed to cure before the procedure is repeated for the following layer. Although support structures are needed for material jetting, they can be created of a water-soluble material that can be removed once the build is finished.
                                                The most expensive 3D printing technique, material jetting, is a precise procedure, but the items tend to be fragile and lose quality over time. However, using this method makes it possible to produce parts in a range of materials in full color.

                                                Powder Bed Fusion:

                                                In the process known as powder bed fusion (PBF), heat energy (such as a laser or electron beam) selectively melts portions of a powder bed to produce layers, which are then layered upon one another to make a part. PBF includes both sintering and melting processes, it should be noted. All powder bed systems operate in essentially the same way: a recoating blade or roller applies a thin layer of powder to the build platform; next, a heat source scans the powder bed surface, selectively heating the particles to cause them to bind. The platform lowers to let the operation to resume after the heat source has scanned a layer or cross-section.

                                                Sheet Lamination:

                                                Laminated object manufacture (LOM) and ultrasonic additive manufacturing are two distinct techniques for sheet lamination (UAM). UAM attaches thin sheets of metal using ultrasonic welding, whereas LOM uses alternate layers of material and glue to form objects with a pleasing appearance. Aluminum, stainless steel, and titanium may all be processed with UAM, which uses low temperatures and little energy.


                                                The two methods of VAT photopolymerization are stereolithography (SLA) and digital light processing (DLP). Both of these procedures employ a light to selectively cure liquid resin in a vat, building pieces one at a time. While DLP flashes a single picture of each entire layer onto the surface of the vat, SLA uses a single point laser or UV source for the curing process. To increase the robustness of the pieces, parts must first be cleansed of extra resin after printing and then subjected to a light source. Additionally, any support structures must be taken out. To produce a finish of greater quality, more post-processing can be applied.

                                                These procedures are perfect for objects that require a high degree of dimensional accuracy and can produce complicated.


                                                Problems in Pakistan and its solution:

                                                Problem:

                                                As we know that theft is increasing rapidly in Pakistan. A thief who steals a motorcycle, car, mobile phone etc. That's why people go to the police station to write complain. I was saying that if peoples write complains in their homes or any where, how will it be?

                                                Solution:

                                                For this we will create an app that allows all people to report their stolen items on this app. People can submit their forms online sitting at home, which will make people's lives easier and whatever complains are registered. All complains will go to the police station and the police will investigate their complains. This app will require you to provide your name, phone number, email, address, and any information about the item that was stolen. As soon as any of your items are found, you will be notified through the  app Or you will be notified on mobile number or email you have given in this app.

                                                Public Suggestion:
