The crude oil tanker volatile vapour cryogenic condensation recovery system is an environmental protection and resource utilization device specially used to capture and recover volatile organic gases (VOCs) generated during crude oil transportation. The system uses a refrigeration device to cool the vapour mixture to a specific low temperature, so that the hydrocarbons in it condense into liquid, thereby achieving effective separation and recovery.
This system is usually installed during berthing and loading and unloading operations or during transportation, and is suitable for various types of crude oil ships. Especially during berthing and unloading or detention at the port, the crude oil in the oil tank releases a large amount of volatile gases due to temperature and pressure changes. Traditional methods mostly discharge them into the atmosphere, which not only causes energy waste, but also pollutes the atmospheric environment. The cryogenic condensation recovery system condenses the vapour back into liquid through technical links such as cooling cycle, heat exchange, and condensation separation to achieve closed recovery.
The system has the following characteristics and advantages:
Significant environmental benefits: effectively reduce VOCs emissions, in line with international environmental regulations (such as IMO MARPOL Annex VI);
High recovery efficiency: can achieve more than 70% vapour recovery rate, and some advanced systems can even reach more than 90%;
Significant economic returns: the recovered condensate can be re-entered into the crude oil system or used as energy to reduce losses;
Improved safety: reduce the emission of flammable gases such as methane and benzene, and reduce the risk of explosion;
Strong system integration: can be combined with vapour recovery platform, liquid cooling station, control system, etc. to form an automated integrated system.
With the increasingly stringent international control of carbon emissions and marine pollution, the low-temperature condensation recovery system of volatile vapour in crude oil tankers is playing an increasingly important role in the upgrading of tanker environmental protection technology, and has become one of the key equipment for green shipping and clean energy transportation.
Main working principle:
Volatile vapour generation: During the transportation and storage of crude oil, due to factors such as temperature changes and pressure fluctuations, light components in crude oil (such as hydrocarbons, solvents, etc.) will evaporate into gas.
Condensation recovery: The system uses a cooling device to reduce the vapour temperature to reach the condensation temperature, so that the vapour are converted into liquid. The condensed liquid vapour can be recovered and sent back to the oil storage tank, avoiding direct discharge of vapour.
Cryogenic cooling: Using cryogenic cooling technology, the gas temperature is reduced to below its condensation point, usually using cooling methods such as liquid nitrogen or refrigeration units.
vapour recovery efficiency: Through cryogenic condensation technology, an vapour recovery efficiency of more than 90% can usually be achieved, greatly reducing volatile organic compound (VOCs) emissions.
Main advantages: Environmental protection: Reduces vapour emissions, reduces air pollution, and meets environmental protection requirements. Resource recovery: Recovered vapour can be reused, increasing economic benefits and reducing resource waste. Safety improvement: Volatile vapour contain flammable and explosive substances, and the low-temperature condensation recovery system can effectively reduce the risk of fire and explosion. Development prospects: With the improvement of environmental protection requirements and the strengthening of resource recovery awareness, the application of crude oil tanker volatile vapour low-temperature condensation recovery system will become more and more extensive. Such systems will play an important role in environmental protection and resource utilization in the future oil transportation, storage and refining process.
