Velan manufactures a full range of pressure seal gate, globe, and check valves for high pressure/high tempera- ture applications. Velan is unique in offering forged bodies and bonnets in sizes up to 24 (600 mm) to improve the quality of the pressure boundary, ensuring that the highest quality material is being used in Velan products. This ensures greaterstrength, structural integrity, and reliability. Velan also uses a new live-loaded pressure seal design, which maintains a bonnet seal regardless of pressure/ temperature fluctuations. > A 10Ԕ (250 mm) pressure seal valve at a refinery in...

Velan is a true global manu-facturing leader. WhatҒs more, our global presence goes far beyond our manu- facturing facilities: our wide range of valves are sold through an extensive network of distribution companies. Our distributors are furthersupported by our North American and European dis- tribution centers, so a Velan distributor is always nearby and ready to help should the need arise. Over the years, Velans large inventories and premier distribution network VelanҒs product stocking program includes a large selection of multi-turn and quarter-turn valves in carbon, chrome, stainless,...

Velanגs Field Engineering Services Departmenthas launched a knowledge base to help main-tenance personnel troubleshoot valve problems. Based on the companys detailedservice issue database, valvediagnostics.com allows users to diagnose their problems andfind a recommended solution. 9 >

The refining process takescrude oil and separates it into useable products. These products range from lubricants to LPG, gasoline, kerosene, residual and distil- late fuels, coke, asphalt, solvents, and petrochemical feedstock. The refining process starts with fractionating, where the crude is sent through two distillation units. The first unit is atmospheric distilla- tion, which separates and recovers the lighter fractions from the fresh crude oil. The reduced crude feed is then sent to the second distillation unit, vacuum distillation, where light, medium, and heavy lube oil is...

The heart of every refinery isthe crude distillation unit. In a crude unit, the oil is heated and the different hydrocar- bon compounds are separat- ed by a process called distil- lation. DistillationӔ means that, at different tempera- tures, the various hydrocar- bon compounds will boilӔ off and be separated from the feedstock. It is important to note that the distillation process is the most common process found in a refinery. Distillation towers are found in almost every type of unit and are used to separate the various hydrocarbon fractions.The atmospheric crude distil-lation tower is...

The cracking process plays a very important role in the refining of oil into fuel prod- ucts. Cracking is the breaking apart of long chains of car- bon molecules. The feed- stocks to crackers are heavyӔ gas oil and cokerӔ gas oil. Both of these prod- ucts contain long carbon chain molecules. When these long carbon chains are heat- ed to temperatures exceed- ing 680F (360аC), they begin to break apart into lighter, more valuable products that can be used as fuels.The purpose of cracking oil isto produce lighter products without producing coke, a natural by-product at high temperatures.
