according toFinished oil and gas recovery deviceThe data on the composition of gasoline, oil and gas components and the emission values specified in the standards are divided into three groups for consideration in the design. The oil and gas condensation unit is segmented and equipped with condensation heat exchangers, consisting of three condensates.

1、 Pre cooling, returning the three condensate residual gas to the "pre heat exchanger" for heat exchange with the ambient temperature oil and gas entering the device, reducing the oil and gas temperature to 3-5 ℃.

2、 By using a refrigeration unit to provide cooling capacity, the incoming oil and gas are cooled to -35 ℃. Set it as a dual heat exchanger with one backup and one in use. When the resistance caused by water vapor frosting reaches around 1000pa, switch to the backup heat exchanger and defrost the deactivated heat exchanger. After defrosting, set aside for later use.

3、 By using a refrigeration unit to provide cooling capacity, the secondary oil and gas are cooled to -70 ℃.

The secondary condensation heat exchanger is set as a dual cold box, one for backup and one for use. When the cold box encounters frost during operation, it can be switched to use and defrosted. Ensure that the oil and gas recovery and treatment device operates continuously for a long time and is required for full oil delivery operations.

The condensation device of the refined oil and gas recovery unit is conducive to the conditions of condensation liquefaction. Firstly, the operating temperature range is set below the boiling point of the corresponding component, and the cooling load configured is calculated to meet the condensation needs; Secondly, in the condenser structure, droplets of heavy components during the condensation process will carry light components for liquefaction, increasing the condensation liquefaction. To ensure the continuous operation of the oil and gas recovery and treatment unit, Unit 2 is configured with 2 sets, ensuring that there is no need to shut down for defrosting if the operation time is long.

We only have each operationFinished oil and gas recovery deviceBy paying attention to the above matters, the normal operation of the recycling equipment can be ensured and its service life can be extended. We know that the normal use of each device is important and is also one of the important aspects of our maintenance, including oil and gas recovery equipment. So we need to follow the correct operating method to ensure the normal operation of the equipment.
