Choose wisely! Ball valves play a significant role in the successful operation of a slurry transportation pipeline. That is why it’s imperative that the best valve selection is made to avoid substantial downtime. Industry Mining Director, Kenny Gorman, explores critical elements to consider in the latest issue of International Mining magazine. Read the featured article, […]
Deal expands specialist group serving the global severe-service valve market Gloucester, UK, 06 December 2021: Severn Group, the global family of specialist high-end valve engineering and manufacturing companies, which includes Severn and LB Bentley, has acquired US-headquartered ValvTechnologies, a leader in the design and manufacture of metal-seated, zero-leakage isolation valve solutions for demanding applications. The […]
ValvTechnologies and Severn Glocon have reached a partnership agreement that will see collaboration between two of the world’s leading engineering and manufacturing companies specializing in innovative, high-end, severe service valves.
Hydrocracking – Application Overview Hydrocracking is a catalytic cracking process assisted by the presence of an elevated partial pressure of hydrogen gas. It is used for feedstock that are difficult to process either by catalytic cracking or reforming. Like hydrotreating, hydrogen is used to purify the hydrocarbon stream from sulfur and nitrogen hetero-atoms. Hydrogen also […]
Continuous Catalytic Reforming (CCR) – Application Overview Reforming is used to convert low-octane naphtha into a high-octane reformate for petrol blending and to provide aromatics for petrochemical plants. It also produces high purity hydrogen for hydrotreating processes. FLOW DIAGRAM Item Applications Temp range (°F) Pressure (psi) Size (in) 1 Feed pump isolation valve 200 – […]
Fixed Bed Hydrotreating – Application Overview This is a licensed process using guard reactors to prevent poisoning of the catalyst. Zero leak catalyst addition and withdrawal isolation valves are critical to the proper functioning of this process. FLOW DIAGRAM Item Applications Temp range (°F) Pressure (psi) Size (in) 1 Feed pump isolation 200 – 320 3200 […]
Naphtha Hydrotreating – Application Overview Naphtha feed comes from crude oil distillation or from delayed coking and visbreaking. It is cleaned and fed to the reformer. FLOW DIAGRAM Item Applications Temp range (°F) Pressure (psi) Size (in) 1 Feed pump isolation valve 200 – 320 1200 – 1300 8 – 12 2 Reactor isolation […]
Hydrotreating – Application Overview Hydrotreating is the process of removal of contaminants like sulfur, nitrogen and metals from refined petroleum products and to saturate olefins and aromatics to produce a clean product for further processing or finished product sales. The process involves the liquid feed being mixed with hydrogen, fed into a heater and then […]
Fluid Catalytic Cracking (FCC) – Application Overview An FCC is used to convert low value gas oils to valuable products like naphtha and diesel and slurry oil. It increases the hydrocarbon ratio by carbon rejection in a continuous process. In this process, a hot “fluid” catalyst at 538°C cracks heavy gas oil feed into gas/LPG, […]
