Automatic oil and gas recovery system that can be remotely monitored

Abstract

The invention discloses an oil gas automatic recovery system capable of remote monitoring, comprising: a main recovery device, which includes a main recovery pipeline, a first recovery group and a second recovery group arranged in parallel with the first recovery group, the first pipeline and the oil gas The intake pipe is connected, and the second pipe is connected with the exhaust gas discharge pipe, so that the first recovery group and the second recovery group alternately carry out the adsorption and desorption of oil and gas; the first recovery group and the second recovery group are equipped with the first adsorption bed and the second adsorption bed, the first adsorption bed and the second adsorption bed are respectively built-in polyvinyl fluoride nanomaterials for adsorption and desorption of oil and gas; oil and gas absorption tank; buried oil tank; monitoring device, which includes a controller and The monitoring device is connected with the controller to monitor the gas concentration at the outlet of the waste gas discharge pipe in real time. The invention can monitor the discharge index in real time, ensures the operation of the system when the discharge reaches the standard, adopts the adsorption bed to rotate adsorption and desorption, improves the operation efficiency of the recovery system, and occupies a small area.

Description

technical field [0001] The invention relates to an oil gas recovery system, in particular to an oil gas automatic recovery system capable of remote monitoring. Background technique [0002] China's total annual crude oil has reached 300 million tons, but due to the limitation of technology, equipment and management level of China's petroleum industry, the consumption of crude oil products in China is quite large. On the other hand, as far as the refined oil sales industry in the downstream industry of the petroleum industry is concerned, light oil products, especially gasoline, will emit a large amount of oil and gas during the process of storage, loading and unloading, and sales, resulting in a certain degree of waste of resources. The existing oil and gas recovery technologies are roughly divided into the following five types: [0003] 1. Solvent absorption type oil and gas recovery system: the disadvantage is that special solvent is required, and the solvent needs specia...

AI Technical Summary

Problems solved by technology

[0003] 1. Solvent absorption type oil and gas recovery system: the disadvantage is that special solvent is required, and the solvent needs special equipment for reduction. The equipment is bulky, the use place is limited, and the absorption efficiency is low. The absorption efficiency can reach 90% at most, which is far from meeting the current requirements. air emission requirements

[0004] 2. Activated carbon adsorption oil and gas recovery system: The adsorption efficiency is low, and it cannot meet the current air emission requirements, and some components in the oil products adsorbed by activated carbon cannot be desorbed, and the adsorption performance decreases with the use of time. It needs to be replaced regularly, and the replacement The final activated carbon belongs to hazardous waste and has secondary pollution, so it needs to be disposed of by a professional hazardous waste disposal company.

[0005] 3. Condensation recovery device: high energy consumption, and the emission cannot meet the existing air emission requirements

[0006] 4. Condensation + membrane + activated carbon adsorption combination process: Although it can meet the emission requirements in a short time, the process is complicated, the equipment cost is high, the energy consumption is high, and the service life is short. It is necessary to replace the filter membrane module and activated carbon regularly, resulting in secondary pollution

[0007] 5. Absorption + activated carbon adsorption process: Although the equipment can achieve high efficiency, it is bulky and troublesome to operate and maintain. Due to the limitations of the use conditions and the use of the site, it can only meet the explosion-proof emission requirements and cannot meet the current new Air Emission Requirements

[0008] Moreover, none of the above-mentioned oil and gas recovery technologies has a monitoring device installed at the exhaust outlet, so the concentration of the exhausted gas cannot be monitored in real time. If the gas emission exceeds the standard and cannot be detected in time, it will pollute the atmosphere, affect the environment and endanger people's health.
