...As with many industries, the chemical, refinery, and petrochemical industries are faced with several corrosion challenges to maintain sustainable development, including the need to use new resources (such as more acidic crude oils or biomass compounds) and to reduce greenhouse gas emissions. Also...

... Downhole Corrosion Inhibitor Application Techniques for Oil and Gas Wells. Circulation Time Required for Rod Pumped Well Batch and Circulate Treatment. Introduction. The phrase “chemical treatment” covers many activities in oil field operations (drilling, production, and plant facilities...

...Numerous chemical products are used in the production of crude oil and natural gas. The types of products include corrosion inhibitors, demulsifiers or emulsion breakers, paraffin inhibitors, scale inhibitors, hydrate inhibitors, drag reducing agents, biocides, oxygen scavengers, hydrogen sulfide...

...This section introduces the important chemical and physical processes that form and remove fouling deposits, including surface chemical reactions, fluid mechanical concepts, corrosion reactions that generate fouling scales, and equilibrium scale deposition processes. Different methods for removing...

...Introduction. The cleaning of refinery, petrochemical, and chemical plant process equipment can be much different than cleaning operations in power generating plants owing to the complex organic deposits and mixed organic/ inorganic deposits in some units. However, the water-contacted sides...

...Chemical cleaning wastes usually contain quantities of metals and other materials that exceed liquid discharge limits of the plants in which the waste is generated. This is a complex subject and is different from state to state, country to country, and plant to plant. Several specific items...

... therefore uncertainty of risk severity and inappropriate chemical dosages. Chemical inhibitors have been widely deployed in the field without appropriate optimization, which has resulted in chemical consumption being listed as one of the top LOE (Loss Of Expenditure) contributors. A number of initiatives...

...Classic corrosion inhibitors are only a part of the arsenal of corrosion-control chemicals and processes used throughout the O&G sector to alleviate corrosive attack. Many of the chemicals and processes described in this chapter act to remove the causes of corrosion and may be used...

...Introduction Production chemicals are used to provide flow assurance, integrity management, and increased production in oil and gas production. Use of these chemicals reduces capital and operating costs of oil and gas production. Flow assurance is the prevention of interruption of flow due...

...Links between Oilfield Chemicals and Corrosion Control Oil and gas recovery, processing, and transportation require the use of many different chemicals for various purposes along the value chain. Oilfield chemistry is at work from the moment drilling begins until products leave the refinery...

...Inhibitors and other corrosion control chemicals must come into contact with the metal surface and/or must be present in a potentially corrosive or scaling fluid stream to be effective. This chapter describes general and specific considerations for conveying a continuously effective...
