LAHORE -- In a bid to recover outstanding dues from both public and private sector defaulters, the Sui Northern Gas Pipelines Limited (SNGPL) on Wednesday disconnected supply to several consumers for not paying cumulative gas bills of over Rs14.140 million.
Calculations and statistical analysis: Total gas production was reported as ml/24 h of incubation (cumulative gas) and methane production was reported as ml/24h and ml/mg IDMD.
SNGPL has disconnected the following defaulters having cumulative gas bills default of Rs.
caudatum culture sediments and medium pH values (HI 8314, Hanna Instruments, Portugal) were recorded every 4 h during the whole incubation period, and cumulative gas productions were calculated from individual recordings (Lopez et al., 2007).
Dried samples were incubated in rumen fluid and buffer mixture in 100 mL glass syringes (Model Fortuna, Germany) (n=6) (triplicate; cumulative gas production plus triplicate; dry matter-organic matter loss).
Although the matrix permeability increases 1.94 times after twelve years of production, it results into an increase by 0.002% in cumulative gas production compared to the standard case.
The statistical design used to evaluate cumulative gas production and dry matter degradability was a 4x4 factorial completely randomized design (four byproducts and four levels of replacement).
Alekperov said between 2007 and 2039, its cumulative gas production from all fields could reach 300 BCM.
Cumulative gas production (CGP) and dry matter degradation (DMD) in vitro studies were conducted using the semi-automatic in vitro gas production technique (MAURICIO et al., 1999), and the potential of maximum gas production, A; colonization time, CT; gas production rate, and effective degradability, ED, were determined according to FRANCE et al.
It clearly shows that, with the increasing of desorption gas volume, gas production will become larger, which is also true to cumulative gas production.
For calibration of the gas chromatograph, the models of non-linear gas production were obtained by fitting data of cumulative gas production to the exponential equation described as p = b[1 - [e.sup.-c(t)]] (Orskov and McDonald, 1979); where p represents the cumulative gas production at time t, c is the rate of gas production (per h), and b equals the potential gas production.
