Assessment of Flammability and Explosion Potential of Waste from Industries

This project presents the work on assessment of flammability and explosion
potential of waste from industries. Nowadays, revolution in lifestyle leads to the
industrial revolution that at last gives some problems of industrial waste which may
be toxic, ignitable, corrosive or reactive. If improperly managed, this waste can
pose dangerous health and environmental consequences. The objective of this work
is to investigate the flammability and explosion potential from a waste generated
from industries by understanding the problem, selecting some mitigation
methodology and preparing the safety analysis. This report will give some
information regarding the hazards of the waste from industries focusing more on
fire and explosion hazards. Two different liquid waste samples are collected from
Kua!iti Alam Waste Management Centre, Seremban, Negeri Sembilan. The
samples have been analyzed using gas chromatography (GC) to measure the
compositions of all combustible species contain in them. The compositions have
been identified for both samples. Gas Chromatography analysis also shows that
both of the liquid waste samples majority are alkane group. It has been found from
the GC results, that the both samples contain water. Therefore, the water extracted
from the sample l and sample 2 using distillation experiments. Some properties
related to flammability study have been measured. The density and heat of
combustion of the waste samples have been calculated also using pyconometer and
bomb calorimeter respectively. The results show that the density of sample 1 is
0.8023 g/ml and sample 2 is 0. 77 g/ml while the heat of combustion for sample l is
26320 J/g and sample 2 is 38354 Jig. The results of the experimental work were
used for consequences analysis to calculate equivalent of TNT mass, overpressure,
impact of overpressure, pool fire and boiling expanding vapor cloud explosion
(BLEVE).
