To All, I need The ISO 8573-2 : 1996, Test methode for sampling and quantitative analysis of aerosol oil content and liquid oil normally present in the air discharged from compressors. mybe anyone know this methode, please help me,because this methode is not present in my library, How can I...

Thank you Kenvlach, the material of fin is aluminium. If I use spray gun some of fin become broken, because the fin condition is very thin. Please, maybe any others solution ?

Thank you Kenvlach for your comment, as the information, the dirt on the surface of airfin cooler is very hard, it is caused by accumulation of dust and the enviroment is humid and also temperatur of system that is cooled is hot, so the dust adher on the surface of the airfin cooler is hard...

Does anyone know how to make Acid Cleaner ( it means the formula or composition ). As the information this acid cleaner will be used to cleaning the fin of airfin cooler, since the surface of airfin cooler somuch scale that caused by dust accumulation. As we know the aqueus cleaner are made up...

I would like to know some opinions on the following question : 1. When We should be used the following detector and what is the difference ? - FID = Flame Ionization Detector - TCD = Thermal Conductivity Detector - FPD = Flame Photometric Detector - FTD = Flame Thermionic Detector - ECD =...

To 25362, Compositepro and Mogi, thank for your interesting to my questions, one more question : What is the dew point will be found same value at any other P and T condition, because dew point is dependent on the concentration of water vapor present and on the relative humidity ? ( It means dew...

Thank you very much 25362, I would like some comment fo your information. I have two kinds table the correlation between dew point and water content. The first table is in the "atmospheric condition ( 760 mmHg )" and the second one is in the "compressed gas". But why if I...

How to convert the result measuring of water / moisture content in the gas phase from pressurise condition ( at various pressure ) to atmospheric pressure ( 760 mmHg ) condition ? Because I have a table correlation "water content to dew point" at the atmospheric condition. For...

Hi Uncleasyd, Thank for you comment, following are the answer for your questions : 1. The gas that compressed is mix H2 70 % and CO 30 %. 2. The rod material construction is stainles steel 13 chrom. 3. The rod crack position on the top near piston. 4. The service life still one year. 5. The...

Hi 25362, Thank you very much for your information. Are those methods ( ASTM D-5454, D-1142 and D-2713 ) suitable for anykind of gas ? because I will use this method for measuring water content in the mix gas ( about H2 73 % and CO 27 % ). Have you method to measuring oil content in the gas...

We have a problem, one of our compressor the piston rod was crack, it is suspected caused by condenseble material (ie. moisture / water content ). Can someone explain us What is the mechanism of piston rod cracking that caused by condenseble material ?, if true the cracking is caused by...

Have you idea a method ( ASTM or others method )are used for determaining water content in the gas phase ( Natural gas, oxox gas etc. ) ? Wahib A

I would like to clean residual oil ( lubricating oil ) in side of pipe line. What kind the degreaser ( or formula degreaser ) suitable fo this purpose and How to the method to clean its ?

we have a problem in the air fin cooler unit system, the problem is so much dust adhere to the surface of air fin cooler, it is caused by the enviroment around our plant is very dusting. The effect of this probelm is heat transfer of the system that is cooled by air fin cooler was decrease...

Hi, We have a problem in a reformer unit of synthetis gas ( oxo gas ),and we think this is due to carbon formation on the surface of catalyst. We would like to ask some questions, as follows : 1. What is cause the increasing of pressure drop in the reformer catalyst ? ( in our system the...
