Noxious gases produced at hazardous concentrations in animal housing systems may affect the health and wellbeing of both animals and workers. In order to determine if the gaseous emissions from a pre-export assembly depot for sheep constituted a risk, atmospheric ammonia was measured in eight sheep buildings at an Australian assembly depot. Additionally, meteorological variables and distance from excreta were measured to determine their influence on ammonia, carbon dioxide and hydrogen sulfide concentrations. Repeat measurements were made at 12 sites in each building on 4 separate days, and four buildings were mapped using longitudinal and latitudinal transects. Concentrations of ammonia, carbon dioxide and hydrogen sulfide were all below the recommended safety thresholds for humans and livestock. There were positive correlations between ammonia and the following variables: ambient temperature and moisture content, and negative correlations with distance from animal excreta. Understanding these relationships will help to understand the reasons for ammonia accumulation in such buildings.

Production Of Hydrogen

Both governmental and international programs support the promotion of biofuels and aim to increase the limit of renewable energy used in the fuel energy balance. Biogas is produced during the anaerobic methane fermentationprocess and it is known as a significant source of renewable energy, contributing to agriculture and environmental protection. Three types of biogas can be distinguished: biogas from sewage sludge, biogas collected from land`fils, andagricultural biogas. There are several possibilities of using upgraded biogas. Biogas can be used in cogeneration systems to provide heat and electricity, in transportation as a motor fuel and in the production of biohydrogen. Biogas upgrading process leads to a product which is characterized by the same parameters as compressed natural gas. Direct biogas use in the production of hydrogen is possible because of prior purification from traces like hydrogen sulfide, except carbon dioxide, by which the reaction can proceed in the desired manner.

Assurance Problem

Liquid condensation in gas-condensate pipelines in a pronounced phenomenon in long transporting lines because of the composition of the gas which is highly sensitive to variations in temperature and pressure along the length of the pipeline. Hence, there is a resultant liquid accumulation in onshore wet-gas pipelines because of the pipeline profile. This accumulation which is a flow assurance problem can result to pressure loss, slugging and accelerated pipeline corrosion if not properly handled.
