3.jpg Participation: Prize of 5 Wealth; Correct answer: Reward of 10 wealth points ; Note: This post is valid for 48 hours. Question: What is the purpose of creating a vacuum before starting a vacuum-condensing turbine compressor in an (DMTO) olefin separation unit? A vacuum must be established; otherwise, after the turbine starts operating, air will not be able to condense, which will result in high exhaust temperatures and high pressures in the recondenser. This can cause deformation of the recondenser and its internal components, thereby affecting the proper operation of the turbine! Note: The answer will be released automatically in two days

A vacuum should be created before startup to remove the air from the exhaust chamber; otherwise, after the turbine starts operating, the inability of the air to condense will cause the exhaust temperature to rise and the pressure to increase, affecting the normal operation of the turbine.

Before starting a condensing steam turbine, the air present inside the system must be removed; otherwise, after the machine begins to operate, the inability of this air to condense will lead to an increase in exhaust pressure and temperature. This can cause deformation of the cylinders and other internal components, affecting the proper operation of the turbine. Therefore, it is necessary to create a vacuum first.

Create a vacuum before starting, evacuate the air from the exhaust chamber to establish a vacuum. Otherwise, after the turbine starts operating, the inability of the air to condense will cause the exhaust temperature to rise and the pressure to increase, affecting the normal operation of the turbine.

This can cause deformation of the steam drum and its internal components, affecting the proper operation of the turbine. Therefore, it is necessary to create a vacuum first.

A vacuum must be created; otherwise, after the turbine starts operating, air will not be able to condense, which will result in high exhaust temperatures and high pressure in the reheat Apparatus This can cause the reheater and its internal components to deform, affecting the proper operation of the turbine
