What are the public media? I only know that there are water, air, natural gas, but I don’t know what others are there. Can anyone add more? ? ? Thanks
There are also steam, nitrogen, instrument air, etc.； Water is divided into industrial water, circulating water, domestic water, demineralized water, etc.
Water (except process water), steam, inert gas, chilled (salt) water, etc.
To summarize: water (industrial water, fire water, desalted water, circulating water, domestic water, chilled water, etc.), gas (compressed air, nitrogen, instrument gas, natural gas, steam, etc.) Electricity
It is difficult to summarize comprehensively, and the public engineering systems that various industries come into contact with are very different. The petrochemical industry often involves: Water, electricity, instrument, gas, wind.
Divided by project boundaries: Water, electricity, steam, compressed air.
