information for software/tools

Hello,
Can somebody give me the names of softwares/tools used for Process engineering (in the power industry) :
Example :

• For Valve sizing
• For HBDs
• For line sizing & P&ID creation (including all the design criteria) etc.

And which companies use these standard software?

Thanks and best regards,
Jaydeep Naha.
