Oxy-propane torches are usually used for cutting up scrap to save money, as LPG is far cheaper joule for joule than acetylene, although propane does not produce acetylene's very neat cut profile. Propane also finds a place in production, for cutting very large sections. Oxy-acetylene can cut only low- to medium-carbon steels and wrought iron ...
However, underwater oxy/fuel gas cutting of any kind has been largely replaced by exothermic cutting [6] because it cuts more quickly and safely. MAPP gas is also used in combustion with air for brazing and soldering, where it has a slight advantage over competing propane fuel because of its higher combustion temperature of 2,020 °C (3,670 °F ...
Methylacetylene-propadiene (MPS) gas is a type of fuel gas used in oxy-fuel welding and cutting torches, comprising a mixture of several gases. MPS gases [ edit ]
About 12 million households use propane to heat their homes. Meanwhile, crude oil prices are also on the rise as stockpiles decline at the same time that worldwide demand is beginning to pick up.

Acetylene (systematic name: ethyne) is the chemical compound with the formula C 2 H 2 and structure H−C≡C−H.It is a hydrocarbon and the simplest alkyne. [8] This colorless gas is widely used as a fuel and a chemical building block.
The justification for using oxy-fuel is to produce a CO 2 rich flue gas ready for sequestration. Oxy-fuel combustion has significant advantages over traditional air-fired plants. Among these are: The mass and volume of the flue gas are reduced by approximately 75%. Because the flue gas volume is reduced, less heat is lost in the flue gas.
Since the start of the third quarter, the price of West Texas Intermediate crude oil has dropped about 15%. The price dipped below $70 a barrel earlier this month before a slight recovery.
