Abstract
This paper aims to provide the elemental composition of particles found in natural gas. Particle sampling is performed on cellulose filters obtained from an industrial gas storage facility, and the qualitative particle composition is determined by scanning electron microscopy and energy dispersive X-ray spectroscopy. Our results establish that natural gas may contain solid particles, with sizes ranging from less than 1 μm to more than 50 μm. The observed particles are composed of numerous elements, such as aluminum (Al), silica (Si), sulphur (S), chloride (Cl), chromium (Cr), zinc (Zn), sodium (Na), manganese (Mg), calcium (Ca), iron (Fe), titanium (Ti), nickel (Ni), vanadium (V), potassium (K), copper (Cu), manganese (Mn), silver (Ag), cobalt (Co), iodine (I), and barium (Ba), with relative occurrences ranging from 1 to 85%. Moreover, metallic elements enable the formation of larger particles as a result of the agglomeration of smaller particles.
Highlights
To ensure a good energy supply, natural gas must satisfy quality specifications to be transported and commercialized and must meet standards in terms of calorific power and chemical composition, with methane, dioxygen, water and sulfur compounds, etc. as the main components [1,2,3,4,5].These specifications ensure high quality gas for combustion but are essential to prevent damage to facilities and protect consumer health
Most of the components are in the gaseous phase, some solid particles can be detected in natural gas
A new cellulose membrane was analyzed under the same conditions and used as a blank to determine the origin of the particles
Summary
To ensure a good energy supply, natural gas must satisfy quality specifications to be transported and commercialized and must meet standards in terms of calorific power and chemical composition, with methane, dioxygen, water and sulfur compounds, etc. as the main components [1,2,3,4,5].These specifications ensure high quality gas for combustion but are essential to prevent damage to facilities and protect consumer health. Studies have revealed the presence of arsenic compounds, mercury and other metals/metalloids in natural gas from different origins at very low concentrations ranging from 10−1 to 103 μg/m3 [6,7,8,9,10,11]. These elements have well-known risks and potentially can cause industrial damage, such as through corrosion or catalytic poisoning. To analyze the particulate phase, the most common sampling technique is filtration
