Seven, methane application

Methane is a very important fuel and is the main component of natural gas, accounting for about 87%. Methane is colorless and odorless in a standard pressure room temperature environment; the special taste of domestic natural gas is an artificial odor added for safety, usually using methyl mercaptan or ethanethiol. In an atmospheric pressure environment, the boiling point of methane is ?161 °C. The gas content in the air is very flammable as long as it exceeds 5% to 15%. Liquefied methane does not burn unless it is in a high pressure environment (usually 4 to 5 atmospheres). According to Chinese national standards, methane cylinders are brown and white.

The pyrolysis of methane can be used to obtain carbon black, which is used as an additive for pigments, inks, paints and rubber; chloroform and CCl4 are important solvents. Methane is widely distributed in nature and is one of the main components of natural gas, biogas and pit gas. It can be used as a fuel and as a raw material for the production of hydrogen, carbon monoxide, carbon black, acetylene, hydrocyanic acid and formaldehyde. Methane is used as a standard fuel for heat value testing of water heaters and gas stoves. Production of standard gas for flammable gas alarms, calibration gas. It can also be used as a carbon source for solar cells, vapor phase chemical deposition of amorphous silicon films. And methane is used as a raw material for the production of pharmaceutical and chemical synthesis.

Eight, matters needing attention

Transportation precautions: The helmet on the cylinder must be worn when transporting in a cylinder. The cylinders should be placed flat and the bottles should be in the same direction. They should not cross; the height should not exceed the fence of the vehicle and be secured with triangular wooden mats to prevent rolling. Transport vehicles should be equipped with the appropriate variety and quantity of fire-fighting equipment. The vehicle exhaust pipe carrying the item must be equipped with a fire-stop device, and it is forbidden to use the mechanical equipment and tools that are prone to sparks. It is strictly forbidden to mix and mix with oxidants. Summer should be transported in the morning and evening to prevent sun exposure. Keep away from fire and heat sources when you stop. When transporting by road, follow the prescribed route and do not stay in residential areas and densely populated areas. It is forbidden to slip when transporting by rail.

Store in a cool, ventilated warehouse. Keep away from fire and heat. The temperature of the reservoir should not exceed 30 °C. It should be stored separately from oxidants, and should not be mixed. Explosion-proof lighting and ventilation facilities are used. It is forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment.

Engineering control: The production process is closed and fully ventilated.

Other harmful effects: The substance may be harmful to the environment and special attention should be paid to fish and water. Special attention should also be paid to contamination of surface water, soil, atmosphere and drinking water.

Closed operation, full ventilation. Operators must be specially trained to strictly follow the operating procedures. Keep away from fire, heat, and smoking in the workplace. Use explosion-proof ventilation systems and equipment. Prevent gas from leaking into the workplace air. Avoid contact with oxidants. Cylinders and containers must be grounded and bridged during transfer to prevent static build-up. Lightly load and unload during handling to prevent damage to cylinders and accessories. Equipped with the corresponding variety and quantity of fire-fighting equipment and leakage emergency treatment equipment.
