How To Design A Filter ?

sorry for the terrible mistake

the specifications are as follow:

- the application is to filter the partially reacted polyethylene and wax that are carried out with the recycled ethylene gas from the low pressure wax seperator to the booster compressor in an LDPE plant

-the mass flow rate is 46 ton per hour

- the pressure is between 1.5 to 2 bar

-the pipe diameter is flexible to optimize the flow

-the temperature is between 40 and 60 Centigrade

again

What are the variables that I should focus on?

and

Is there a comprehensive source that I can go to?

Thanks
