Firstly, the methanol gasoline blending function tank is distributed. In the newly-built gasoline tank farm, transfer two 3000m3 methanol gasoline blending special tanks, and return them to the tanks for cleaning, requiring no water, no grease, no oxide colloid and no mechanical impurities. Other gasoline tanks are used as intermediate tanks for raw oil (atmospheric naphtha and catalytic gasoline), blending tanks for methanol gasoline base oil and settling and dewatering tanks.

2. Mixing step

The gasoline produce by that atmospheric and vacuum distillation unit and the catalytic unit respectively enters the gasoline intermediate tank, when the gasoline in the tank reach a safe height, the oil supply is stopped, the gasoline is allowed to stand for 48 hours, and the clear wat is removed through a plurality of slow dehydration ports. The dehydrated blending components are transferred to a gasoline blending tank according to a certain proportion (atmospheric naphtha: catalytic gasoline: enhancer) for basic blending of methanol and gasoline, and RON is required to be controlled between 88 and 89. After laboratory analysis, the blended methanol gasoline base oil was allowed to stand for more than 24 hours for dehydration. After the base oil is dehydrated, it is transported to the methanol gasoline blending tank by pumps (special pumps and special pipelines), and 3% (volume ratio) methanol is injected for cyclic blending. After the blending time is over, it can be sold after laboratory analysis and standing for 2 hours.

Requirements: Methanol gasoline must be mixed in special tanks and sold in special tanks (oil return and tank cleaning of gasoline for special railway lines require no water, no grease, no oxide colloid and no mechanical impurities).

3. Others

When trains and cars are loaded, the tank cars must be inspected to ensure that there is no water accumulation. Once there is water, the tank must be cleaned to ensure that there is no water, no grease, no oxidized colloid and no mechanical impurities.

Rainproof measures must be taken during loading, and it is best not to load methanol and gasoline in rainy days.

The user must be informed that the gasoline is methanol gasoline, and the discharging tank of the other party must be free of water, grease, oxide colloid and mechanical impurities.

Verb (abbreviation of verb) related knowledge

1. Vehicle methanol gasoline refers to a new clean fuel made by adding a certain volume ratio of denatured fuel methanol to gasoline component oil.

2. The characteristics and advantages of methanol gasoline for vehicles are:

Strong power: after methanol is mixed with gasoline as a high octane number component, the octane number of methanol gasoline is increased by 1-2 units compared with gasoline of the same grade. High octane number can increase locomotive power, which is obviously superior to gasoline at high speed.

High cleanliness: methanol in vehicle methanol gasoline is an excellent organic solvent, which can effectively eliminate the precipitation and condensation of impurities in the fuel tank and oil system of the vehicle itself, and also eliminate the carbon deposits formed in spark plugs, valves, piston tops, exhaust pipes and silencers.

Cleaner and more environmentally friendly: methanol gasoline contains oxygen and sufficient fuel, which can greatly reduce carbon monoxide and hydrocarbons in tail gas emissions.

3. Please note:

Methanol is a hydrophilic liquid and easily soluble in water. When using methanol gasoline for the first time, it must be confirmed that there is no water in the vehicle fuel tank. At the same time, methanol gasoline for vehicles has a strong cleaning function. At the initial stage of use, impurities such as dirt, rust and carbon deposit attached to the fuel tank wall or deposited on the bottom of the fuel tank, the inner wall of the fuel pipe, the spark plug, the valve, the piston top, the exhaust pipe and the muffler will be washed away and sucked into the oil supply system by the fuel pipe, resulting in the gasoline filter element or carburetor atomizing nozzle and the nozzle of the EFI vehicle being blocked by impurities. Therefore, before using methanol gasoline for vehicles, the oil circuit system must be inspected and cleaned to avoid oil circuit failure.

4. What is the power and fuel consumption of methanol gasoline compared with ordinary gasoline?

The engine bench test and driving test conducted by the National Automobile Research Center show that the engine does not need to be modified, and its power performance is basically unchanged. Especially on the high compression ratio engine, at the same calorific value, the fuel consumption is 3-8% less than that of gasoline, the high-speed fuel consumption is obviously reduced, and the climbing performance is strong.

5. The hazards of methanol gasoline for vehicles:

The use of methanol gasoline is equivalent to that of gasoline. As long as the operating rules are strictly observed, it will not cause harm to the human body. Don't take it orally and don't try it.

6. Symptoms caused by inhaling or accidentally drinking methanol gasoline for vehicles.

(1) Inhalation of methanol gasoline vapor can cause headache, dizziness, nausea and tachycardia. (2) Mistaken drinking will cause vomiting, gastrointestinal mucosal irritation, and then convulsions, anxiety and heart failure. (3) Long-term skin contact will lead to degreasing.
