Bete Supplies Nozzles For Ethylene Application

Bete has supplied custom-designed Maxipass nozzles for a chemical processing application that involved oil quenching in the production of ethylene. Ethylene feedstock is usually ethane, propane, butane or a number of other feedstocks. The feedstock is mixed with steam and heated to a temperature of about 1,500F to cause the reaction that converts it to ethylene in the pyrolysis furnace.

It is downstream from the pyrolysis furnace where Bete's specialist nozzle expertise is required, as part of the cooling process where it is necessary to cool the process stream in order for the chemical reactions to take place correctly. This is accomplished by injecting oil into the process stream to reduce the temperature and it is critical to have a good spraying pattern into the process stream to ensure effective cooling, according to the company.

Bete was given a specification that gave the temperature and pressure outside the nozzle, along with the temperature, viscosity, type of fluid, density and available pressure across the nozzle. The solution was the Bete Maxipass series of nozzles, which is designed for hydrocarbon feed applications. This nozzle offers a uniform distribution and a good drop size and is available in a range of materials. The material chosen was 316L stainless, which the company has many years of experience fabricating.

Bete is a distributor of standard and custom-designed spraying solutions for a range of industries and applications. Orders are handled from stock-holding facilities and are supported by technical and application support. Bete is also an exclusive distributor for spray nozzle specialist Bete Fog Nozzle and pre-treatment spraying systems manufacturer Uni-Spray Systems.

The standard range of industrial spray nozzles consists of thousands of different options in many different materials, including brass, stainless steels, Hastelloy, Stellite and Tantalum. More than 65 per cent of the company's production is geared towards custom solutions. Bete also offers economical, customised, non-corrosive nozzle systems, couplers and adaptors in PVC, CPVC, polypropylene, PVDF and stainless steel that are suitable for pre-treatment applications.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
