Gas explosion caused by argon plasma coagulation of colonic angiodysplasias.
established tool to treat lesions of the gastrointestinal mucosa, such as angio− dysplasias [1]. Cases of colon perforation after gas explo− sion caused by APC have been recorded since 1976 [2], especially after prepara− tion with mannitol [3], which seemed to increase hydrogen gas production. Newer data suggest that stools remaining in an incompletely cleaned bowel may be the main cause for ex...
متن کاملColonic gas explosion during therapeutic colonoscopy with electrocautery.
Therapeutic colonoscopy with electrocautery is widely used around the world. Adequate colonic cleansing is considered a crucial factor for the safety of this procedure. Colonic gas explosion, although rare, is one of the most frightening iatrogenic complications during colonoscopy with electrocautery. This complication is the result of an accumulation of colonic gases to explosive concentration...
متن کاملExplosion Severity: Propane versus Natural Gas
Natural gas, composed mainly of methane, is in some ways similar to propane gas. Both fuels have similar energy densities per unit mass, and similar laminar premixed flame burning velocities. However, propane explosions have been shown to produce higher overpressures in unconfined explosion tests when compared to methane. In vapor cloud explosion modeling, methane is considered to be a “low” re...
متن کاملRoot Cause Analysis of NIOC\'s 20" Natural Gas Explosion
Transmission and distribution pipelines have a significant role in the oil and gas industries. Pipelines are facing different threat like corrosion, improper design and incorrect operation. Gas vapor released from a pipeline (owned by NIOC) failure spread out and reached to ignition source. Due to gas outdoor spreading, “flash fire” occurred and flame return caused “vapor cloud explosion” of ga...
متن کاملParametric Generation of Explosion Scenarios for Quantitative Risk Assessment of Gas Explosion in Offshore Plants
In this study, probabilistic risk assessment has been carried out for the prediction of gas explosion loads due to hydrocarbon leaks and subsequent explosions in the topside of offshore platforms. In the initial phase of the risk assessment, the effect of various scenario parameters on the annual probability of gas explosion was quantified via a MATLAB code. For calculating the gas explosion fr...
