There are many kinds of oil and gas recovery equipment, and the recovery technologies adopted by different recovery equipment are different. Now there are absorption recovery technology, adsorption recovery technology, condensation recovery technology, etc. Different recovery technologies have different advantages. Now we see many main turbidity condensation recovery equipment, and this recovery equipment has more advantages. Condensation recovery equipment is used to cool steam from gas and condense it into liquid, which is suitable for recovering harmful substances in steam state. The operation of this equipment is relatively simple, and the recovery rate is also high, which can better improve the oil and gas recovery rate.
In the process of condensation recovery, the condensed matter only changes physically and its chemical properties remain unchanged, so it can be directly recycled. It is often used as a pretreatment process to purify high-concentration organic waste gas, which can reduce the load of subsequent processes and recover valuable substances from two aspects: reducing pollutant content and reducing waste gas volume. This method is suitable for the working conditions of high concentration, low temperature and small air volume of organic waste gas, and requires auxiliary refrigeration equipment. It is mainly used for the treatment of organic waste gas in petroleum, chemical and pharmaceutical industries.
Condensation recovery equipment effectively combines the advantages of condensation method and adsorption method. Because of the enrichment of oil and gas by adsorption system, the oil and gas to be treated by tertiary condensation is greatly reduced, and the energy consumption of condensation recovery is also reduced. The oil and gas after secondary condensation is medium-low temperature oil and gas, and the activated carbon bed will not produce high-temperature hot spots, and the adsorption system also overcomes related hidden dangers. In order to prevent the function and accuracy of the equipment from decreasing to the specified critical value or reduce the failure rate, the maintenance activities, condition detection maintenance and regular maintenance are two maintenance methods according to the pre-established plan and technical requirements. Condition-based inspection and maintenance is an additional preventive maintenance method for the actual technical status of oil and gas low-temperature condensation and recovery equipment. The equipment is inspected daily and regularly to find out the technical status of the equipment. In view of the deteriorated position and degree of the equipment, preventive maintenance is carried out in time before the failure occurs, and the hidden troubles are eliminated to restore the function and accuracy of the equipment. Regular maintenance of oil and gas low-temperature condensation recovery equipment is a way to prevent maintenance from the running time of the equipment. According to the wear and tear law of the device, the maintenance category, maintenance interval, maintenance content and technical requirements are determined in advance. The maintenance plan can be arranged according to the planned starting hours of the device.
Condensation recovery equipment can be divided into contact condensation and surface condensation. Contact condensation is the direct contact between cooling medium and waste gas for heat exchange, which has the advantages of good cooling effect and simple equipment. However, it is required that the components in waste gas will not react chemically with the cooling medium and will not be mutually soluble, otherwise it will be difficult to separate and recover. In order to prevent secondary pollution, the condensate should be further treated. Surface condensation is to use partition walls to separate the exhaust gas from the cooling medium, so that they are not in contact with each other, and remove the heat in the exhaust gas through the partition walls to cool it. Therefore, the condensed liquid is pure and can be directly recycled. The equipment of this method is complex, and the amount of cooling medium is large. It is required that the pollutants to be cooled do not contain particles or sticky substances, so as to avoid deposition on the wall of the device and affect heat transfer.
Therefore, condensation recovery equipment can better improve the recovery efficiency of oil and gas. At ordinary times, we do a good job in the maintenance and protection of oil and gas recovery equipment, which can prolong its service life. Therefore, it is necessary to do a good job in the maintenance of recycling equipment when using it.
