The volume of heavy, sour crude oil processed by North American refineries is steadily increasing, and along with it a commensurate demand for hydrogen to upgrade that oil. A steam-reforming process that would allow refiners to produce their own H2…
Newlight Technologies (Irvine, Calif.; www.newlight.com) has launched commercial production of a polyhydroxyalkanoate (PHA) thermoplastic made from air and greenhouse gases, such as methane, that can be manufactured less expensively than conventional petroleum-derived alternatives, using a novel high-efficiency biocatalyst and bioreactor…
One of the most significant limitations on the operation of dynamic compressors (axial and centrifugal compressors) is the low-flow limit known as “surge”. A sudden valve closing, such as for emergency shutdowns or for a suction/discharge valve, presents significant challenges…
The prices of low-voltage variable frequency drives (VFDs) have declined substantially since they were introduced, while the cost of power has increased. Normal project economics will now justify these VFDs — which go up to 375 kW (500 hp) or…
Many CPI applications require the injection of chemicals, such as corrosion inhibitors, precipitation inhibitors, oxygen scavengers and countless others, into the process during operation. Follow these tips to design and operate a system that ensures accurate delivery of performance chemicals,…
The new V Series modulating ball valve is designed for controlling pressure, temperature flow and level. The valve body is available in carbon or stainless steel with NPT, Socket Weld, Tri-Clamp and 150# or 300# flanged end connections. Sizes are…
The new high-performance ultraviolet (UV) absorber Hostavin 3330 disp. XP enhances the durability and UV protection of waterborne coatings, enabling them to reach the performance of conventional solvent-borne systems, says the producer. Hostavin 3330 disp. XP has an active UV…
By expanding the valve line to include drive sizes up to 130 mm, globe valves, angle seat and diaphragm valves of the Element Series can now be used to achieve fittings up to orifice dia. DN 50. The expanded area…
This company has unveiled an innovative, flush-batten-aluminum geodesic dome design, which may be considered a new paradigm in engineered cover technology. OptiDome features a double web I-Beam for strength and stability, plus optimized patent-pending, batten seal technology that eliminates environmental…
Manual operators are often included on solenoid valves to enable functional checking during startup and commissioning. These operators are then removed prior to the plant being handed over to operations personnel to prevent potential trips or unplanned shutdown. The new…
