31/8/2017#0183;#32;However, the occurrence of corrosion during gas dehydration can be blamed on several issues, such as the water content in the feed gas stream, oxygen ingress (air ingress), impurities in the gas stream, and high temperature for glycol regeneration.

Galvanic corrosion occurs when there are two dissimilar metals or alloys in an electrolyte. In a plant, for example, a humid area with steel pipes and copper fittings could experience this type of corrosion, as one metal would become an anode and the other a cathode, accelerating oxidation.
Corrosion may be defined as material attack which is chemical or electrochemical in nature. Widespread attack General corrosion, FlowAccelerated Corrosion (FAC) Localized attack Galvanic corrosion (between dissimilar metals), Crevice corrosion, Cracking Pitting EROSION VS. CORROSION 21 2 March 2017
Galvanic corrosion or bimetallic corrosion is important to consider since most of the structural industrial metals and even the metallic phases in the microstructure alloys create galvanic cells between them and/or the Mg anodic phase. However, these secondary particles which are noble to the Mg matrix, can in certain circumstances enrich the corrosion product or the passive layer, leading to a decrease or a

To provide a common base of gas processing knowledge and allowing easy communication with others in the oil and has industries. To give a clear knowledge on the various types of corrosion that will affect the equipment in the gas processing plant. To provide guidelines on degradation mechanisms and corrosion control
Galvanic corrosion occurs when two different metals have physical or electric contact with each other and are immersed in a common electrolyte or when the same metal is exposed to an electrolyte with different concentrations. In a galvanic couple, the more active metal (anode) corrodes at an accelerated rate and the more noble metal (the cathode) corrodes at a slow rate.
A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.

Galvanic corrosion (also called bimetallic corrosion) is an electrochemical process in which one metal corrodes when it comes into contact with another metal that is of dissimilar type. The corrosion is caused by a selfinduced current created when the two dissimilar metals are in contact in the presence of an electrolyte such as fresh potable
