Understanding your strength

Material strength Strength is the highest value of stress that a material can hold. If a material gets a stress above this limit, the material will break. How do we know the strength of the material? By doing laboratory testing, we can understand this value. And what is stress? technically, stress is the quantity of load divided by perpendicular area of material that receives the load. The higher the load, the higher the stress. The smaller of the area, the higher the stress value. How to reduce the stress of material to avoid a material break? simply increase the area or decrease the load. Your strength Your strength is the highest value of work stress that you can hold. If you get a work stress above this limit, then probably you will be “break”. Unfortunately, you can not do laboratory testing to find out this limit. You can only feel it. You can push your self to this limit to feel the “break”.

CO2 removal from Natural gas in Ammonia Plant

CO2 removal unit in Ammonia Plant The raw material for the ammonia plant is natural gas. but unfortunately, many gas wells contain CO2 so that CO2 gas is very disturbing the process of making ammonia. In general, CO2 gas is discharged at the front of a factory or known as the front end process. Natural Gas will enter the CO2 removal unit. in this unit, an MDEA liquid will remove the CO2 gas from the natural gas stream. In general, there are 2 high vessels or columns which are the core part of this CO2 removal unit. On the left side, that is yellow is a CO2 absorber vessel. The function of this vessel is to capture or absorb CO2 gas from Natural Gas then CO2 gas will be carried by MDEA solution. MDEA solution which is rich in CO2 gas is channeled to the green right vessel. Here, CO2 gas will be released or separated from the MDEA solution. corrosion problem in CO2 removal unit there are some common corrosion problem in this CO2 removal unit inside the equipment and outside the equipment. CO2 gas is corrosive and erosive. This will create corrosion-erosion in piping especially in the elbow area[…]

ASME ANSI API ASTM code standard

Code, Standard and handbook in oil and gas industry

Code, Standard, and handbook are terms that are very often heard in the environment of Engineers and professionals working in the oil and gas industry. In general, the standard is a technical definition as well as instructions directed at the designer, manufacturer, operator or user of a piece of equipment. Whereas the Code is a standard that has been recognized by a government agency and authorized by law. So that the Code is stronger and binding because it is a legal document. The Handbook is very detailed and very complete technical information about a particular theme. For example, the ASM Handbook Volume 13 concerning corrosion. In the Handbook explained the basics of the theory of corrosion that is very complete. including the basic theory of how to measure corrosion rates in a laboratory. Whereas ASTM G102 is a Standard for Rates and Related Information from Electrochemical Measurements. If we want to master the science of corrosion, then we must understand the handbook about corrosion. if we want to master and expert as practitioners in calculating corrosion rates, we must understand ASTM G102. Codes and Standards do not provide detailed instructions on a design process, nor do they provide instructions on[…]

GIS in oil and gas industry

GIS introduction, data management in oil and gas industry

GIS data management requirement Today we have entered a modern era that relies a lot on the information system in every aspect of life with developing the technology is significant. This rapid development also occurred in scientific field of Geodesy & Geomatics, especially Geographic Information Systems (GIS) that has been applied in various fields during many years. GIS can rapidly grow like this for the support and implementation in other scientific fields. Geology & Geography (G & G) that uses GIS applications to support Exploration &  production activities of Coal Methane (Coalbed Methane / CBM) as Non-Conventional Hydrocarbons; especially in the processes of acquisition, processing, and presentation of information. Exploration & production activities of Non-Conventional Hydrocarbons including in the oil & gas industry with its characteristics are high risk-high return. That is, industry this has a high risk, requires large costs, and using the latest technology, but promising benefits big & worth it. Therefore, data management & information that used, must have a high level of accuracy & precision. Spatial analysis of GIS much help in solving problems that arise on oil and gas exploration & production activities. GIS application in the oil and gas industry GIS has become an[…]
