Liquefied natural gas is safe, says PTT



BANGKOK, 14 March 2016 (NNT) - PTT Public Company Limited, a Thai state-owned oil and gas company, reassured that public that liquefied natural gas is very safe compared to other common fuel types.

Responding to a criticism about the safety of LNG which followed a boat explosion that took place in Saen Saeb Canal, Executive Vice President of the PTT Somkiat Masunthasuwun said the public should not be drawing any conclusions about the incident until investigation results are revealed.

He said LNG is produced by cooling natural gas and has the best safety record of all common fuel types; therefore, it is very difficult for LNG to ignite. In addition, when LNG spills on the ground or water it vaporizes quickly and leaves behind no residues. As LNG vaporizes, the vapor cloud can ignite if there is a source of ignition, but otherwise LNG dissipates completely.

As a result, the executive vice president asked all sides to refrain from making negative criticisms.

Why on earth is anyone trying to say it is the gas that was at fault for that boat explosion?

LNG has been used for a very long time all over the world. Instead they should be looking at the maintenance records (if any) of that boat. There is about a 99% chance that explosion happened due to old equipment or worn seals on the gas tank. Typical, people want to look outside when it's most likely human error and no safety checks being done on these public transportation boats.

So what fuel was the boat actually using?

I doubt it was LNG, more likely CNG/NGV or LPG.

When it's a liquid it's not dangerous; but when the liquid becomes a gas, it's dangerous ;

A truck tanker is not dangerous when full of liquified gas, but it's a bomb when the tank is empty because it's full of gas .;

The air vent must be open when the tank is empty .

Yep, we know it's safe,... completely FACEsafe, KABOOOOOOM!!!!

Sure, but the liquid nitrogen needed to cool LNG to -160 degrees might give you an ittybitty frostbite.

So which is it really, CNG or LPG?

[jerome2]

This is CNG it cannot be liquid in a non cooled tank

it is compressed natural gas

it is it its liquid state only in the ships

WIKI:

The natural gas is condensed into a liquid at close to atmospheric pressure by cooling it to approximately −162 °C (−260 °F); maximum transport pressure is set at around 25 kPa (4 psi).

A boat would not be using LNG. LNG is stored at -161C which I doubt if a boat has the facilities to achieve this. What they mean is CNG there is a world of difference. Gas, as is well known within the industry, is by far more dangerous than benzene. telling people it is the safest is a bit of a porky

Lng is the same cng liquid nat gas

compressed nat gaz

No it isnt. It is compressed but but s not the same as LNG. Obviously you have never worked in the LNG industry or you would realise the difference.

LNG is primarily used for distribution to countries and is not actually compressed. When delivered to a country in LNG form processing then takes the LNG to gas not liquid. From there is gas is distributed to th local gas companies. The process is a heat extraction method whilst CNG is compressed. Before stating what you believe to be facts please gain some knowledge of the industry.

LNG is not used by consumers, it is a product that is received and processed ready to sell to consumers

the burning at the boat shows first black smoke then explosion happens.

there is something else probably hte cause of the fire.

Regarding gas

the fire then shows spreading of the flames upwards that is not happening with LPG.

LPG goes down and spread first and you see the flames 'walking' over the water/soil/ground.

LPG is heavier than Air and move down.

Hydrogen and CNG/ LNG are lighter and move up.

they collect up but if they can find a crak in the sealing the will go to the creak in to the air

That is why you have many problem with LPG in closed areas as the LPG is collection around the car in a garagebox or a parking lot. Then at a certain level it will be able to ignite due to the concentration gas./ai ,makes is possible to self ignite.

that is why gas fules /bi fuel car need to be parker in well ventilated areas.
