Analysis of flammability limits for the liquefaction

3. Flammability limits analysis. In the designed process, the oxygen-bearing CBM undergoes the stages of compression, liquefaction, throttling and distillation while the impurity gases (including methane, nitrogen and oxygen) undergoes the process of cold energy recovery in LNG-100 and LNG-101. Flammability hazard may exist in these operation

Experimental study of flammability limits ScienceDirect

Because of the lack of flammability limits at low temperatures, in this study, an experimental setup was built to measure the flammability limits of methane/air mixtures at a wide temperature range from 123 K to 273 K and pressure range from 0.1 MPa to 0.9 MPa. The results show that the trend of flammability limits at the initial low

Flammability Diagram – Under various temperature and pressure conditions, liquids will evolve a certain quantity of vapours. For pure substances, the vapors evolved in air at atmospheric pressure may be flammable over a certain range of concentrations defined by the upper and lower flammability limits. If the oxygen concentration in air is

Lower Flammability Limit an overview | ScienceDirect

Two limits of solvent flammability exist. The lower flammability limit is the minimum concentration of solvent vapor in oxidizing gas (air) that is capable of propagating a flame through a homogeneous mixture of the oxidizer and the solvent vapor. Below the lower flammability limit, the mixture is too lean to burn or explode. The upper

This is because the DMR liquefaction process has a higher efficiency and larger LNG production capacity in a single train than SMR or the nitrogen expansion liquefaction process 9. In general, the NG liquefaction process has three NG cooling stages: pre‐cooling, liquefaction, and sub‐cooling. The DMR liquefaction process uses one kind of MR

Coalbed methane liquefaction adopting a nitrogen

Coalbed methane (CBM) is an important global energy resource and liquefaction is suggested to best utilize it. Different from ordinary natural gas, CBM usually contains a high proportion of nitrogen, which cannot be removed by purification procedures applied in ordinary natural gas liquefaction processes.

Lignocellulose Liquefaction to Biocrude: A Tutorial Review

24/01/2018· The liquefaction of lignocellulose to biocrude and subsequent refining to biofuels are no new concepts. Liquefaction was subject of intensive research after the oil crises in the 1970ies and regained interest at the turn of the 21 th century. Much understanding has been gained, for example, on the chemistry of the process, the chemical

NATURAL GAS SPECIFICATION CHALLENGES IN THE LNG INDUSTRY

To prevent liquid dropout, natural gas pipeline companies limit the amount of butane, pentane and heavier components. LNG plants must remove heavier hydrocarbon components to prevent freezing in the liquefaction process, and the heavies removed become a natural gasoline by-product. Heavy end specifications are therefore not difficult

Simulation Research on Influence of Coal Mine Gas

In this paper,simulation calculation was carried out on the coal mine gas liquefaction process with HYSYS software,and analysis was made on the influence of gas concentration upon the economic benefit and safety of the coal mine gas liquefaction process. The results showed that the change of gas concentration had a greater impact on the total energy compression of the coal mine gas
