Control of corrosion in oil and gas production tubing

L. SMITH Controlling corrosion in production tubing is essential for maintaining production and for preventing loss of well control. Materials for use downhole have to meet criteria for corrosion resistance and also mechanical requirements. The potential corrosion rate can be estimated and the risks of sulphide stress corrosion cracking assessed on the basis of the anticipated environmental con...

Corrosion of Different Materials in Combustion Chamber of Yellow Phosphorus Tail Gas in Industrial Boiler

About 75% of yellow phosphorus produced in the world is from China, and Yunnan province produces 60% of that in China. Yellow phosphorus is mostly produced by electric furnace from phosphate minerals. Through this method, 2500-3000 Nm/t tail gas is emitted, which causes pollution of the atmosphere. The key composition of the tail gas contains 80%~95%CO. Due to the “3R” principle (reducing, reus...

Multilayer Nano Films for Corrosion Control

Nano films consisting of an alternating sequence of positively and negatively charged polyelectrolytes have been prepared by means of the electrostatic layer-by-layer (LBL) sequential assembly technique on treated and untreated mild steel wires. Inhibitor was encapsulated between cationic and anionic polyelectrolyte nano films. This paper mainly focuses on the effect of these nano-films of poly...

water treatment for corrosion control

certain gases, principally oxygen,o , and carbon dioxide, co , dissolved in water accelerate its corrosive properties. the rate of corrosion is approximately in prportion to the quantity of gas dissolved. the removal of gases from water, as practiced in steam station, is effected by mechanical and thermal treatment , by addition of chemicals, or by combinations of these processes, the most wide...
