The water needs cleaning thoroughly to make it clean and usable again. The save-water projects are getting more critical with time, and therefore, the government and other companies are willing to work on wastewater treatment. It follows with the act of ensuring the tank being oxygen-less for the process. Here is an example of a P&ID drawing that shows how vegetables and agricultural wastes initiate biogas production. Biogas production is complex in nature, and it takes some time. The processing of CO2 and H2S may create some disruption sometimes, but the P&ID drawing can help the engineer fix it without much hassle.īiogas production and processing of the raw material are widespread as the usage of green energies is increasing. As the P&ID drawing shows, there are many steps that the firms need to follow to get the work done. The companies working in the oil and gas sector widely use this process for sweetening the gas.

The example shows another complex work process, namely amine absorption. The processing of the gases within the gas follows some steps, and the example P&ID drawing shows an accessible diagram format of the process. It involves the combustion of oxygen with certain other gases like natural gas, propylene, hydrogen, and nitrogen as a carrier. The drawing of the example here shows a thermal spray process. The P&ID drawings can make a complicated process look relatively less complicated. The P&ID drawing explains how the process goes on till the company distributed it to the gas stations. The chain begins with the production and import of crude oil, which then goes through the refinery. Here is an example of P&ID drawings, which show the five-tier structure of a gasoline supply chain. The P&ID shows how the workflow goes, which helps the users identify the disruption in the flow or specific other issues related to the work process structure.
