Enhance ethylene cracker radiant tube integrity through innovative robotic inspection
The ethylene cracker plays a crucial role in the petrochemical industry, producing more than 200 MMtpy of ethylene globally, which is the major building block for plastics, synthetic rubber, lubricants and various chemicals.
Navigating the complex LNG value chain
Throughout the last two decades, LNG technology improvements have built a global natural gas market. This globalization has led to an increase in demand, but also an increase in instability, as changing global events and the drive towards increased sustainability in energy sources have created market fluctuations from all directions.
Directly calculate pipe diameters through valves and fittings under a turbulent flow regime
Calculating pipe diameters through long, straight pipes is executed in classic fluid flow problems using traditional trial-and-error methods or by complex equations.
Flare flow measurement
Flare gas meters are used in facilities such as oil rigs, refineries and chemical plants to measure the gas flows in flare lines. In many parts of the world, this is a regulatory requirement.
API strengthens piping inspection standards with new updates
The American Petroleum Institute announced the release of the fifth editions of API 570, Piping Inspection Code: In-service Inspection, Rating, Repair, and Alteration of Piping Systems; and Recommended Practice 574, Inspection Practices for Piping System Components, two foundational standards for safeguarding piping systems used in the global refining and petrochemical industries.
Eni's Plenitude unit valued at 10 B euros in deal with EIP
Eni has agreed to sell a 9% stake in its low-carbon and retail unit Plenitude to Energy Infrastructure Partners (EIP) through a deal that values the unit at 10 B euros ($11 B) including debt.
Case study: Forced-circulation evaporator piping design
Evaporation and crystallization techniques have many applications in the chemical, fertilizer, metallurgical, chlor-alkali, pigment and dye, food, ash treatment and zero-liquid discharge process industries, among others.
Arranging lines in a pipe rack: How to standardize pipe spacing in the oil and gas industry
This article provides deep insight to piping layout engineers, presenting a holistic/systematic approach for pipe spacing based on different pipe supports—e.g., rest, guide, shoe and clamps (rather than assuming spacing based on 50-mm or 75-mm clearance between pipes).
Differential thermal expansion and welding problems in dissimilar joint of carbon steel to austenitic stainless-steel piping in high-temperature applications
Joining dissimilar piping materials has found widespread application in various process plant piping, most notably in jacketed piping with carbon-steel jackets and austenitic stainless-steel core piping with stainless-steel end closures that require welding to carbon-steel jacket piping.
Control reciprocating compressor pressure pulsations to ensure long-term operational reliability
Reciprocating compressors receive and deliver gas in discrete slugs (or pulses) as the pistons move back and forth.
