This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Magnetite Processing Common
Themes & Differences
> Availability of water, water conservation and high cost of water are
common themes
> Water is scarce and the cost of acquiring process water is increasing
> Water quality is important with chloride limits in the product &
processing issues
> Balmoral use sea water, Karara use bore water and Southdown use pit
dewatering and run off water
> Water is a sensitive environmental issue

Water Quality For Processing
> Salinity
- Fresh water - Less than 1,000 ppm
- Slightly saline water - From 1,000
ppm to 3,000 ppm
- Moderately saline water - From
3,000 ppm to 10,000 ppm
- Highly saline water - From 10,000
ppm to 35,000 ppm
- Ocean water contains about 35,000
ppm of salt
- Hypersaline - >35,000 ppm TDS
> Acidity alkalinity
> Chemical analysis
> Pollutants
> Hardness

Water Quality For Processing
> Water quality is an important issue in mineral processing operations
such as flotation, flocculation, gravity & magnetic separation, grinding,
thickening and filtration
> Approximately 80% of water utilised by the mineral industry is sourced
from underground- bore fields- desalination is a relatively new source
> Water strategy in terms of quality: “fit for purpose”
> Examples:
- Mt Keith Nickel Project: uses 15,000 – 20,000 mg/L TDS
- Some gold projects in WA: use 300,000 mg/L TDS with pH 3-3.5 for CIP/CIL
- Plutonic good quality water- SRB’s (sulphate reducing bacteria)
- Paddington- HCN gas levels

Water Quality Issues
> Accumulation of chemical species in recycled water
> Climate impacts on recycled water - build up of salts
> Use of ground water impacts on quality
> Increased cost of water
> Increased maintenance - corrosion issues

Conduct A Water Audit & Analysis
> The water quality circuit constitutes a complex system
> System analysis - absolutely necessary
> Three main levels at which a system can be identified
Level 1 – Unit Operations
Level 2 – Processing Plant
Level 3 – Site Water Tasks

Methodology for Appraising a
Waste Water Re-use Project
> Internal recycling
- Low tech, low risk
- Fast track, greatest impact
- Lowest capital and operating cost
> Holistic Approach – Consider
- Total capital and operating cost (life cost)
- Mineral processing plus waste management
- Various waste treatment options
- Various water quality requirements
- Minimise processing of water
38. > RESOURCE PROJECTS > TECHNOLOGY > INTEGRATED SERVICES> Mineral Processing > Engineering Design > Training > Specialist Services
Classify Water Types & Quality
> Start paying attention to types, use and quality
> Raw water (bore water, sea water, stream)
> Tailings return water
> Process water (worked water)
> Potable water (drinking)
39. > RESOURCE PROJECTS > TECHNOLOGY > INTEGRATED SERVICES> Mineral Processing > Engineering Design > Training > Specialist Services
Water Balance
> Water In= Water out but can
you account for it ?
> Seasonal changes upset the
balance - tropical vs. dry
climate
> Ore type can change the
balance - clays
> Cant manage what you don’t
measure
> High evaporation rates

Specific Magnetite Issues
> Water quality important for reverse flotation (no slimes)
> Product has limits with respect to salt content
> Balmoral/Karara/Southdown different approaches - location
> Filtration of large volumes of tailings is mandatory and has
not been done before
> Desalination has environmental issues with respect to
reject stream dispersion
> Bores can only be used on a sustainable basis - reporting,
license, no drawdown, black art

Specific Magnetite Issues
> Mineral processing can improve its management of water
quality
> Mineral processing plants can improve recycling
> Auditing and system analysis will assist and is the most
appropriate
> Water circuits are complex
> Industry will face a number of challenges with water
> Desalination is only a part of the solution

Summary
> Water has to be managed as a precious
resource
> Quantity & quality
> Cost likely to increase - fees for extraction?
> Recycling should be a high priority
> Carry out a risk assessment
> Assess effect of water on process
> Management based on measurement - Risk
Analysis
> Water Issues are complex and cannot be
considered in isolation - many impacting
factors
> Mining companies must win the
environmental hearts and minds of people in
the cities
