According to the performance and characteristics of Roots vacuum unit, the economic benefits of replacing steam jet vacuum pump in vacuum distillation unit are summarized. It has many functions, but it is not well known. Then the next small edition for its application in petroleum distillation, to make a simple introduction for you, let's take a look at it.
The traditional vacuum pump of steam jet is used as the main means of evacuation in almost all the vacuum distillation units of domestic refineries. Although the water steam jet vacuum pump is simple in structure, small in maintenance and reliable in operation, it consumes a lot of water steam and cooling water, but the vacuum obtained is relatively low, which makes the crude oil not get deep displacement and the oil displacement rate is relatively low. In addition, there are a lot of condensate mixed with the condensate of oil vapor, which wastes oil and causes serious environmental pollution In other countries, the so-called "dry distillation" is used in the refinery pressure reducing devices. In addition to the transformation of the original decompression tower.
Roots vacuum pump unit is mainly to select and modify the design of the evacuation equipment. Roots vacuum pump with return air-conditioner is used as the main pump in the United States to overcome the heating of Roots vacuum pump under high pressure. The two-stage water ring vacuum pump is selected as the front stage vacuum pump to form the air extraction unit. In addition, a cold source is needed to maintain the long-term operation of the unit. Therefore, the design structure is more complex and the cost is more expensive.
Roots vacuum pump unit has a wide range of applications. It can't only be used in common fields. In fact, it can also be seen in many industries with partial doors. It plays different roles in different industries and fields. Therefore, it is necessary to be more careful in product selection.
