, Description:TECHNICAL FIELD:
The present disclosure relates to the field of metallurgy. Particularly, but not exclusively, the present disclosure relates to a system and method for detecting deposits in a pipeline. Further embodiments of the present disclosure disclose system and method for detecting the concentration of sediment deposits in the industrial pipeline such as pipeline used in steel plants.

BACKGROUND OF THE DISCLOSURE:

Generally, during carbonization of coking coal in a coke oven battery for the production of coke, around 25-30% of the coal charged is driven off as effluent gases rich in volatile matter and moisture. This gas is known as coke oven gas (CO gas). Coke oven gas (CO gas) is a byproduct gas produced during the production of metallurgical coke in a byproduct coke oven battery, where metallurgical coal is carbonized by heating it in absence of air. During carbonization, the volatile matter in the coal is vaporized and driven off. This volatile matter leaves the coke oven chambers as hot, raw coke oven gas. Coke-oven gas is a fuel gas having a medium calorific value that is produced during the manufacture of metallurgical coke by heating bituminous coal to temperatures of 900°C to 1000°C in a chamber from which air is excluded. The main constituents are, by volume, about 50% hydrogen, 30% methane and 3% higher hydrocarbons, 7% carbon monoxide, 3% carbon dioxide and 7% nitrogen. The gas has a heating value of about 20,000 kJ/m3.

Typically, coke-oven gas is obtained from a battery comprising number of narrow, vertical chambers, or ovens built of silica brick that are separated by heating ducts, such that heat is transmitted to the coal through both sides of the chamber walls. The ovens are slightly tapered so that one end is wider than the other to facilitate the horizontal discharge of the coke. Crushed coal is charged from overhead bunkers into the ovens, which are sealed at each end by refractory-lined sheet doors and heated. The hot coke is then discharged. About 12%, by weight, of the coal is converted into gas. The hot gases evolved from the coal pass through a gas space at the top of the oven and into a collecting main prior to quenching and treatment to remove dust, tar and oil, and gaseous impurities such as ammonia and hydrogen sulfide. Also, the coke-oven gas includes impurities such as naphthalene and tar.

After leaving the coke oven chambers, the raw coke oven gas may be directed into the coke-oven gas pipeline. As the pressure in the gas pipeline is significantly equal to the atmospheric pressure, impurities/sediments begin depositing in the pipeline. As a result, over a period of time the sediments completely get deposited in the pipeline which may result in several downsides in the production process. Also, due to the sediment deposits, the pipelines get blocked which is a substantially bigger problem in the steel industry. The sediment deposition hinders the flow of coke oven gas which affects the production process. Blockage of pipelines lead to a poor operating efficiency and increase the risk of potential accidents.

There are also known prior arts to determine deposition of sediments in the pipeline. For instance, the prior art US20050041775A1 discloses a method for high-speed radiographic inspection of a fluid vessel using a radiation source and a radiation detector. The source and detector move longitudinally (and circumferentially) with respect to vessel to map the image of deposit present inside the pipeline. The device of US20050041775A1 poses a serious radiation hazard; it can’t be used for pipeline at greater heights. Moreover, the method disclosed in US20050041775A1 will fail to map the bends. In another known prior art, WO2007008636A1 discloses a conventional method for determining deposition parameters within an industrial heating system using phased array probe. In the method disclosed in WO2007008636A1, sediment deposit must be intact with the surface of pipe so that reflected acoustic wave is received by phased array probe. In gas pipelines, sediment get deposited with time; they are porous in nature and hence acoustic wave will not be able to travel back to the probe.
The present disclosure is directed to overcome one or more limitations stated above or other such limitations associated with the conventional systems.

The information disclosed in this background of the disclosure section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

It is to be understood that a person of ordinary skill in the art may develop a system of similar configuration without deviating from the scope of the present disclosure. Such modifications and variations may be made without departing from the scope of the present invention. Therefore, it is intended that the present disclosure covers such modifications and variations provided they come within the ambit of the appended claims and their equivalents.

Equivalents

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

It will be understood by those within the art that, in general, terms used herein, are generally intended as "open" terms (e.g., the term "including" should be interpreted as "including but not limited to," the term "having" should be interpreted as "having at least," the term "includes" should be interpreted as "includes but is not limited to," etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding the description may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (e.g., "a" and/or "an" should typically be interpreted to mean "at least one" or "one or more"); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of "two recitations," without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to "at least one of A, B, and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, and C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to "at least one of A, B, or C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, or C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B."

While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated in the description.
