Coalescing gas separators are designed specifically for the removal of mist, fog, and dust from gas streams. These contaminants usually exist with the bulk of the particles having diameters considerably less than 10 microns; therefore, standard separators or scrubbers are not capable of effectively...

API 650 is the industry standard for the design and construction of large, field-erected storage tanks that operate at atmospheric pressure or low internal pressures (not exceeding 2.5 psig). These tanks are essential for safely storing crude oil, petroleum products, water, chemicals, and other...

Sand Separators. In the oil and gas industry, it is more commonly known as a separator and is a core component of extracting oil from earth and sand. Sand separators are an integral part in protecting downstream production equipment from well-formation sand and/or frac...

Shell and tube heat exchangers are one of the most common types of heat exchangers used in various industries, including oil and gas, chemical processing, power generation, and HVAC systems. They are versatile and reliable, capable of handling a wide range of fluids and...

A three-phase separator is a crucial piece of equipment in the oil and gas industry, designed to separate a mixture of oil, gas, and water into its individual components. The vertical three-phase separator, equipped with a downcomer and spreader, is a particularly efficient design...

Double-pipe heat exchangers are a simple yet effective type of heat exchanger that consists of two concentric pipes. One fluid flows through the inner pipe, while the other fluid flows through the annular space between the two pipes. This design provides a compact and...

Fluidized bed boilers (FBBs) use a unique combustion method where solid fuel particles are suspended in an upward flow of air — creating a fluid-like state. This allows for highly efficient combustion at lower temperatures with improved emissions control.

Magnetic separators utilize magnetic forces to separate magnetic materials from non-magnetic materials. They are widely used in various industries, including mining, recycling, and food processing. Magnetic separators are a valuable tool for separating materials based on their magnetic properties. By understanding the principles of...

A vertical separator is a cylindrical vessel that is oriented vertically. When a gas-liquid mixture enters the separator, the heavier liquid phase settles to the bottom, while the lighter gas phase rises to the top. The liquid phase is then drawn off through a...

Learn the key differences between ASME Section I and Section IV boilers, including pressure limits, inspection requirements, and why choosing the right code matters for safety and compliance.

Applicants for new issuance or renewal of an ASME® Certificate(s) of Authorization should be aware that the Joint Review will require implementation and demonstration of their Quality Control Program. The purpose of the demonstration is to have the Applicant provide evidence of their knowledge...

The ASME® B31.1 Code for Power Piping is a widely recognized standard that provides guidelines for the design, fabrication, and installation of piping systems for power plants. This code ensures the safety and reliability of piping systems by establishing rigorous design and construction standards.
