Does the absorption tower being used to absorb oil and gas at around 100 degrees have an impact on the tower?
Thread Content
There is now a absorption tower that is needed to absorb the vapors from vehicles; the oil in question is diesel, and the volume of these vapors is 3000 m3 per hour at a temperature of around 150 degrees. Could this pose any risks?
Every time I see a post like this, I get anxious. I have some money in my pocket now, and I want to buy bananas. Ten yuan per pound of bananas, and they are really delicious. I plan to buy five pounds. Do you think I have enough money? Do you think I missed mentioning some important information? Think about it carefully.
Because you were in a hurry, there wasn’t enough money. Am I right: lol
I guess the poster is referring to exhaust gas recovery in gasoline loading/unloading trucks. A major risk is the oxygen content in the recovered oil and gas; when gasoline is loaded, poor sealing at the transfer hoses and the tank tops of the tankers can cause the oil and gas recovery system to draw in air. If it exceeds the limit, the explosive limit is reached in the absorption tower at 150 degrees. May I ask how the original poster controls the oxygen content in the recovered oil and gas?
First, you need to check whether the operating conditions of your equipment’s process permit it. It’s allowed if it’s within the range; it’s not allowed if it’s outside the range.
What you are absorbing is a mixture of oil vapor and air, and this certainly poses risks, as it may fall within the explosive range. Strict anti-static and explosion-proof measures are necessary. It’s best to leave this task to design firms or manufacturers specialized in VOCs handling; attempting to do it on your own can easily lead to problems
If there is no air in the oil and gas, aren’t the potential hazards much reduced?
I would like to ask about the gasoline content in the oil and gas mixture. Is 3000 m3/h the volume of gas? Also, is the temperature of the oil and gas 150°C? If it is 150 degrees Celsius, there must be some risks involved, right? Generally, oil and gas recovery employs processes of activated carbon adsorption and diesel absorption. During the regeneration of the activated carbon, the temperature of the carbon bed usually does not exceed 110°C; if this temperature is exceeded, an alarm is triggered. The gas resulting from regeneration enters the absorption tower, and a combustible gas alarm is installed on the pipeline leading to the absorption tower to prevent flash explosions due to high concentrations.
Could the temperature of the oil and gas collected during gasoline loading be 150 degrees? The source of this temperature value is incorrect, right? Furthermore, at such high temperatures, explosive gas mixtures can easily catch fire or explode when exposed to static electricity or high-temperature heat sources; it is recommended that the owner consult a design firm
