Assignment Activity 1: Estimate the shell thickness for a standard pressure vessel, using relevant design codes.

The relevant design code is ASME Section VIII, Div. 1. Shell thickness for a standard pressure vessel can be estimated using the following equation:

t = (P x S) / (2 x π x R)

Where t is the shell thickness in inches, P is the design pressure in pounds per square inch, S is the allowable stress in pounds per square inch, R is the radius of curvature in inches, and π is approximately 3.14.

For a design pressure of 10,000 pounds per square inch and allowable stress of 20,000 pounds per square inch, the shell thickness would be approximately 0.5 inches.

Assignment Activity 2: Size a relief valve for a variety of upset scenarios.

There are a variety of ways to size a relief valve for upset scenarios. The most important thing is to make sure that the valve is sized correctly for the system it is protecting. Over-sizing or under-sizing the valve can lead to problems. 

One way to size a relief valve is to use the American Petroleum Institute (API) Recommended Practice 520, Sizing, Selection, and Installation of Pressure-Relieving Devices in Refineries. This practice provides guidance on sizing pressure-relieving devices based on process conditions. 

Another way to size a relief valve is to use process safety information (PSI). PSI includes data such as maximum allowable working pressure (MAWP), maximum design pressure (MDP), and maximum allowable burst pressure (MABP). This data can be used to calculate the required relief valve capacity.

Finally, the most conservative way to size a relief valve is to use the ASME Boiler and Pressure Vessel Code (BPVC). The BPVC provides guidelines for the safe operation of pressure vessels. It includes rules for sizing relief valves based on the operating pressure and temperature of the vessel.

Assignment Activity 3: Select a material of construction for a specific application.

In general, the best material for construction for a specific application depends on several factors, including the environment in which the structure will be used, the weight and size of the structure, and the budget available for construction.

Some materials are better suited than others for certain applications. For example, steel is a good choice for heavy-duty construction because it is strong and durable. However, it is also expensive and can corrode in certain environments. Concrete is a less expensive option than steel but is not as strong or durable. It is best suited for applications where weight is not a concern, such as in foundations or walls.

When choosing the construction material, it is important to consider all of the factors involved to make sure the best possible decision is made.

Assignment Activity 4: Complete a mechanically-focussed design project for an equipment item for a specified unit operation on an individual basis, featuring

A mechanically-focussed design project for an equipment item can be very beneficial for students who are interested in pursuing a career in engineering or a related field. By working on a real-world project, students can gain valuable experience and skills that will be useful in their future careers. Additionally, completing a project on an individual basis can help students to better understand the concepts they are learning and how to apply them in a practical setting.

1. Complete detailed chemical-engineering design from scratch, with sophisticated process-modeling software.

The process-modeling software can be used to create a complete detailed chemical-engineering design from scratch. This software can be used to create a model of the process, and then optimize the design for maximum efficiency. Additionally, the software can be used to calculate important process parameters such as mass and energy balances.

The use of process-modeling software is a valuable tool for chemical engineers. It allows them to quickly and easily create detailed designs of complex processes. This software can help to improve the safety and efficiency of operations, and can also help to reduce costs.

2. Complete detailed mechanical design in accord with design codes, with full compensation and combined-stress analysis, including support requirements, for a variety of scenarios.

To complete a detailed chemical-engineering design from scratch, you’ll need to use sophisticated process-modeling software. This software will enable you to create models of the processes and equipment involved in your project. With these models, you can experiment with different designs and operating conditions to find the best solution for your needs.

3. Specify pressure relief system.

A pressure relief system is a feature of some mattresses that allows air to escape from the mattress, which helps to prevent excessive build-up of heat and moisture. This can be especially important for people who perspire at night, as it can help to keep them more comfortable and cool.

There are several different types of pressure relief systems, but the most common is the hole-punching system. In this type of system, small holes are punched into the surface of the mattress, which allows air to escape. Other types of pressure relief systems include channels (which allow air to flow between different parts of the mattress), valves (which release air when pressure builds up), and gel bladders (which absorb heat and moisture).

4. Develop P&ID.

A process and instrumentation diagram (P&ID) is a schematic illustration of a chemical or physical process. It shows the piping and vessels, as well as the instrumentation, controls, and other equipment involved in the process. The P&ID is used to document the design of a chemical or physical process, and to help communicate that design to others.

5. Develop start-up standard operating procedures based on P&ID.

A standard operating procedure (SOP) is a set of written instructions that describe the specific tasks to be carried out to produce a specific product or service. SOPs are designed to ensure that all employees within a company are performing their work in the same consistent manner, thereby minimizing errors and maximizing efficiency.

When starting a new business, it’s important to develop detailed SOPs for all key operations, including manufacturing, sales and marketing, accounting and finance, and human resources. The SOPs should be based on your company’s specific processes and procedures and should be tailored to the individual roles and responsibilities of each employee. They should also be reviewed and updated regularly to ensure that they remain current.

Assignment Activity 5: Demonstrate an understanding of the regulatory framework for equipment design.

In Ireland, the regulatory framework for equipment design is set out in the Equipment Design Regulations 2018. These regulations provide for the approval of designs for certain types of equipment, including pressure vessels, lifting appliances, and electrical installations. The approval process ensures that equipment meets the relevant safety standards and is fit for its purpose.

To obtain approval for a design, the designer must submit a written application to the competent authority. The application must include a description of the equipment, a list of the safety standards that it meets, and proof that the equipment has been successfully tested.

The Equipment Design Regulations 2018 are available on the Irish Statute Book website.

Assignment Activity 6: Show a detailed understanding of safety, loss prevention, and design practice in the context of embedded sustainability and ethics.

To ensure safety, loss prevention, and sound design practice in the context of embedded sustainability and ethics, it is important to consider the following:

  1. Safety: First and foremost, safety must be paramount in any design consideration. Hazards must be identified and assessed, and risk management strategies must be put into place to mitigate potential harm.
  2. Loss Prevention: It is also important to consider ways to avoid or minimize losses – whether they be financial, environmental, or social. Measures may include designing for durability and recyclability, using renewable resources whenever possible, and incorporating closed-loop manufacturing processes wherever feasible.
  3. Design Practice: Sound design practice is essential for ensuring that products are well-made and fit for purpose. This includes using appropriate materials and manufacturing processes, as well as ensuring that products are durable and easy to maintain.
  4. Embedded Sustainability and Ethics: Finally, it is important to consider the impact of a product on the environment and society throughout its entire life cycle. This includes factors such as energy consumption, emissions, material use, and social and labor standards.

The concepts of embedded sustainability and ethics are complex and often overlap. It is important to take a holistic approach when considering these factors and to ensure that the needs of all stakeholders are taken into account.

Assignment Activity 7: Synthesise a plant-scale process flow sheet and complete associated mass and energy balances.

The first step in synthesizing a plant-scale process flow sheet is to complete mass and energy balances for the desired process. This will give you information on what materials are required for the process and how much energy will be needed to operate it.

Once you have this information, you can begin designing the flow sheet. The flowsheet should include all unit operations necessary to carry out the process, as well as their associated mass and energy balances. With a complete understanding of the process and all its inputs and outputs, you will be able to design a scalable plant-scale process flow sheet.

Assignment Activity 8: Document the plant-wide design appropriately, using PFDs, P&IDs, mechanical drawings, specification sheets, and plant layout drawings.

A plant-wide design generally refers to the engineering design of a manufacturing or treatment plant layout as a whole. It includes the process flow diagrams (PFDs), piping and instrumentation diagrams (P&IDs), mechanical drawings, and electrical schematics.

The purpose of a plant-wide design is to provide an overall view of the facility that can be used by operators, maintenance personnel, and engineering staff to troubleshoot problems and make modifications. It also provides a basis for costing the project and for issuing requests for proposals (RFPs) to suppliers.

The plant-wide design should be based on the process specifications, which in turn should be based on the required product quality and production rate. The PFDs and P&IDs should be drawn to scale, and the mechanical drawings should include all pertinent dimensions. The electrical schematics should show the circuit arrangement and identify all components.

In addition to the engineering drawings, a plant-wide design typically includes specification sheets that list the required materials and equipment for each unit operation. It may also include a plant layout drawing that shows the general arrangement of the process equipment.

Assignment Activity 9: Demonstrate an understanding of safety, environment, and sustainability in process design.

To ensure safety, environment, and sustainability in the process design of a chemical manufacturing plant, the following measures are typically taken:

  • The plant is designed with safety in mind. This means that all equipment and processes are designed to minimize the risk of accidents.
  • The plant is designed to minimize its environmental impact. For example, it is typically located close to waterways so that effluent can be easily discharged into the environment without causing harm. It also uses less energy than traditional plants and recycles or reuses as much waste as possible.
  • The plant is also designed to be sustainable. For example, it uses renewable energy sources where possible, and has a reduced carbon footprint. It also meets or exceeds all environmental and safety regulations.

To ensure that these measures are taken, the process designer needs to have a comprehensive understanding of safety, environmental, and sustainability principles. He or she should be familiar with regulatory requirements and how they can be incorporated into the design of the plant.

Assignment Activity 10: Carry out plant-economics exercises.

To determine the feasibility of a chemical manufacturing plant, it is necessary to carry out plant-economics exercises. This involves estimating the capital and operating costs of the plant, as well as the revenue that can be generated from its products.

The results of these exercises will help to determine whether or not the plant is economically viable. If the costs are too high or the revenue is too low, the plant will not be viable and should not be built.

The process designer must have a good understanding of plant economics to carry out these exercises accurately. He or she must be familiar with the cost of materials and equipment, as well as the cost of labor. The designer must also be able to estimate the revenue that can be generated from the plant’s products.

Assignment Activity 11: Conduct a HAZOP.

A HAZOP (Hazard and Operability) study is a structured and systematic examination of a process or system to identify potential hazards and operability problems. A HAZOP aims to prevent or mitigate potential accidents, incidents, and emergencies by identifying hazards and analyzing the risks associated with them. 

There are many different ways to conduct a HAZOP, but the most common approach is to use a guided worksheet. This worksheet will list all of the steps in the process or system under examination, as well as key operating parameters (e.g., temperature, pressure, flow rate). For each step and parameter, the team will brainstorm possible deviations from normal operating conditions (known as ” What-if ” scenarios) that could lead to a hazardous event.

The HAZOP team should include representatives from all areas of the process, including engineering, operations, and safety. It is important that everyone involved in the study be familiar with the process and the potential hazards associated with it.

The results of a HAZOP can be used to identify hazards that need to be addressed in the design of the plant. It can also help to identify areas where additional safety training is required.

The process designer must have a good understanding of HAZOP principles to carry out a HAZOP study effectively. He or she must be familiar with the types of hazards that can occur in a chemical process, as well as the steps involved in a HAZOP. The designer must also be able to lead a team of experts in carrying out a HAZOP study.
