Hydrotreating
Upgrading the bottom of the barrel
In the past few decades, new technologies, including both carbon rejection methods and catalytic conversion methods, have emerged.
Metallurgy solution to prevent polythionic acid stress corrosion cracking in hydroprocessing
Hydrotreating is a staple process found in nearly every refinery. The process removes undesirable feed contaminants, such as sulfur, nitrogen and metals, and saturates olefins and/or aromatics to produce high-quality products.
Consider pitot tube pumps for low-flow, high-head applications
Low-flow, high-head pumping requirements in refining and petrochemical plants make up less than 2% of the total pump population. This minor percentage is creating significant reliability concerns, which result in low mean-time between failures (MTBF), as well as high maintenance costs.
Production of renewable fuels in existing refinery assets: A cost-effective coprocessing strategy
Vegetable oils are a renewable biomass resource used in the production of biofuels. Biodiesel production from transesterification of vegetable oils (fatty acid methyl ester, or FAME) is the primary route for producing biofuels from vegetable oils.
Details on high-impact refining and petrochemical projects presently under construction, as chosen by HP editors and readers
The global hydrocarbon processing industry (HPI) continues to expand and modernize to efficiently meet growing demand for energy, transportation fuels and petrochemicals.
Industry Perspectives: The latest in refining technology
Nearly 700 refineries are operating in more than 120 countries around the world.
Optimization: Filtration for processes inside refineries
Proper filtration is one of the most important functions performed inside refineries.
Optimize a refinery H2 network using spreadsheet tools
One of the major goals in every refining complex is to minimize the utilization of its hydrogen (H<sub>2</sub>) generation units by maximizing the H<sub>2</sub> recovery from residual streams.
Indian refiner HMEL chooses Topsoe equipment for refinery upgrade
Indian refinery company HPCL-Mittal Energy Ltd (HMEL) has chosen Topsoe’s diesel hydrotreater unit and hydrogen generation facilities to meet their upgrading requirements.
Improve energy efficiency with enhanced bundles in tubular heat exchangers
From 2008 to date, 45 twisted tube heat exchangers and bundles have been installed at BAYERNOIL refineries in different units and services, allowing higher heat recovery and contributing to BAYERNOIL’s energy targets.
