Tanks are an important part of the oilfield process equipment, and are used for a variety of purposes in the oil and gas industry. Tanks are typically used for storing various types of liquids and gases, including crude oil, refined products, natural gas liquids (NGLs), and water. They can also be used for processing and separating different components of the oil and gas stream.

Tanks come in a range of sizes and designs, and are made from materials that are suitable for the specific application. For example, crude oil storage tanks are typically large, cylindrical structures that are made from carbon steel or other corrosion-resistant materials. NGL storage tanks, on the other hand, are often smaller and designed to operate at lower pressures and temperatures.

In addition to storage, tanks are also used for process applications, such as separation, treatment, and refining. For example, tanks may be used for separating oil, water, and gas, or for treating contaminated water or gas streams. The use of tanks in the oil and gas industry helps to optimize the production process and ensure that the final product meets the necessary quality and safety standards.

Overall, tanks play a critical role in the oilfield process equipment, and are an essential component of the oil and gas industry.
