Need help in Filter Housing Design...!

I have to design the filter housing using the data provided below.
Can anybody help me ,how to calculate the shell diameter and length of the shell of filter housing.which all formula are taken into consideration into filter Housing design ??

Flow Rate Normal : 400 m3/hr
Flow Rate Design: 440 m3/hr
Mass Flow rate : 1130 kg/hr

Design Pressure - 16.78 kg/cm2
External Pressure - 0.2-0.3 kg/cm2
(Full Vacuum)
Hydro static Pressure-25.20 Kg/cm2
Working Temperature- 50`C
Design Temperature: 100`C
corrosion Allowance : 6mm
pressure drop at design flow:0.06 kg/cm2
Operating Fluid : VCM Vapor

Please help me out.

Sure, I'd be happy to help you with your filter housing design! There are a few different factors to consider when determining the shell diameter and length for your filter housing. Here are some steps you can follow to calculate these dimensions:

1. Determine the required flow rate: The first step is to determine the maximum flow rate that your filter housing needs to handle. In this case, the flow rate design of 440 m3/hr is the maximum flow rate that the housing needs to accommodate.

2. Determine the cross-sectional area: The next step is to determine the cross-sectional area of the filter housing. This can be calculated by dividing the flow rate by the fluid velocity. For example, if the fluid velocity is 1 m/s, then the cross-sectional area would be 440 m3/hr / 1 m/s = 440 m2.

3. Determine the shell diameter: Once you have the cross-sectional area, you can calculate the shell diameter by using the formula for the area of a circle: A = πr2, where A is the cross-sectional area and r is the radius of the shell. Rearranging the formula, we get r = √(A/π). Plugging in the cross-sectional area from step 2, we get r = √(440 m2/π) = 10.54 m. Therefore, the shell diameter would be approximately 21.08 m (2r).

4. Determine the shell length: The shell length can be calculated by dividing the required flow rate by the cross-sectional area. In this case, the shell length would be 440 m3/hr / 440 m2 = 1 hr. This means that the filter housing should have a length of at least 1 hour's worth of flow rate, or 1 hr x 3600 s/hr = 3600 m.

5. Consider design pressure and temperature: The design pressure and temperature of the filter housing will also impact the dimensions. In general, a higher design pressure and temperature will require a thicker and longer shell to withstand the stress and heat. You may need to consult with an engineer or refer to industry standards to determine the appropriate thickness and length for your specific design conditions.

6. Incorporate corrosion allowance: The corrosion allowance of 6mm should also be taken into consideration when determining the dimensions. This means that your shell diameter and length should be increased by 12mm (6mm on each side) to
 

1. What is a filter housing and why is it important?

A filter housing is a container that holds a filter element, which is used to remove impurities or contaminants from a fluid. It is important because it ensures that the fluid flowing through the system is clean and free from any harmful particles that could damage equipment or affect the quality of the end product.

2. How do you determine the appropriate size for a filter housing?

The size of a filter housing is typically determined by the flow rate, pressure, and temperature of the fluid being filtered. These factors will determine the required surface area of the filter element and the material and thickness of the housing to withstand the operating conditions.

3. What materials are commonly used for filter housing design?

The most commonly used materials for filter housing design are stainless steel, plastic, and aluminum. Stainless steel is a popular choice for its durability and resistance to corrosion. Plastic is often used for its lightweight and cost-effective properties, while aluminum is commonly used for its strength and ability to withstand high temperatures.

4. What are the key features to consider when designing a filter housing?

Some key features to consider when designing a filter housing include the type and size of filter element, the material and thickness of the housing, the connection type and size, and the pressure and temperature ratings. Other factors to consider include ease of maintenance, compatibility with the fluid being filtered, and any regulatory requirements.

5. How can I ensure the filter housing design meets industry standards?

To ensure the filter housing design meets industry standards, it is important to consult relevant codes and standards, such as ASME and ASTM, during the design process. It is also recommended to perform thorough testing and analysis, including pressure and flow tests, to ensure the housing can withstand the expected operating conditions and effectively filter the fluid. Additionally, seeking input and feedback from experienced engineers and industry experts can help ensure the design meets industry standards.
