A New Method to Detect Blockage in Gas Pipelines

In this article, a new testing equipment and protocol in order to evaluate acid gas scavengers for direct chemical injection into gas pipelines is described. The testing protocol address several shortcomings in previous accepted tests which did not take into account the formation of a spray of the product, or tested the product in its final formulation.

Oil Gas

Total methane content in the atmosphere has increased for two times during last two hundred years. Since 1900s, the annual rate of growth for methane dramatically increased. The sources of methane emissions to the air are their storage reservoirs, different oil-gas refineries, main pipelines and their transport facilities as well. A new method for detection of methane escape from the main pipelines has been developed and the order of its realization shown. Mathematic algorithm of the method is presented and the calculation formula for optical thickness of methane over the track obtained. Obtained formula allows diagnosing the escapes in gas pipelines distantly. Block-scheme of operation algorithm of the realization of offered method has been developed as well.

The Cost

An important environmental problem is exceeding the current sanitary standards on the territory of thermal power plants (TPP) and in the surrounding residential area. One of the intense sources of noise at the TPP is the gas distribution points (GDP) and the gas pipeline after it. The noise at the exit of the GDP building and along the length of the gas pipeline can be 110 dBA. Effective methods of reducing noise from GDP and gas pipelines are the installation of acoustic barriers and the use of noise insulation materials. The most effective is a set of measures to reduce noise including the joint use of the barrier and noise insulation. The cost of noise reduction measures depends on many factor, including the type of materials, the thickness of the construction as well as the required amount of noise reduction. Earlier in the works of the authors, it was shown that when planning noise reduction measures, it is necessary to achieve equality of the specific reduced costs by using noise insulation and acoustic barriers. This will ensure minimal noise reduction costs. In this paper, the economic effect of using the new method is considered. A new formula is proposed for determining the economic losses in the case of inequality of the specific reduced costs for shielding and noise insulation. It is shown how the economic losses increase in the case of an increase in the ratio between the specific reduced costs of shielding and noise insulation.
