New Product Alert: AE902-1 Hazardous Area Class I, Division 2, Access Point Enclosure for Aruba AP 318

AE902-1
The Analynk AE902-1
Analynk is proud to announce a new access point enclosure, the AE902-1, specifically for the Aruba AP-318 access point.

Aruba, a Hewlett Packard Enterprise company, developed the Aruba 318 series access point as a hardened device for use in harsh, weather-protected environments. Aruba designs some of the most popular and highly rated access points in the industry.

Analynk developed the AE902-1 to house the Aruba AP-318 for use in hazardous areas. The enclosure, all hardware and antennas are rated for Class I, Division 2, groups A, B, C, & D. 

A POE (Power over Ethernet) injector and AC to DC power supply, are included. The enclosure is made of 316 stainless steel and has a NEMA 4X rating for harsh conditions, such as offshore oil and gas platforms. Optional directional antennas are available, and antennas can be mounted up to 150’ away from the enclosure. The AE902-1 can be flat panel or pole mounted.

As mentioned above, the AE902-1 is currently rated Class I, Division 2 Groups, A, B, C, & D. ATEX Zone 2 approval is pending.

See the drawing below. For more detailed information, inquiries, or to download a Sales Specification Sheet, visit this page on the Analynk website.

Understand Petroleum Refining for Better Process Control Support

Oil refinery petroleum refinery
Oil refineries can have different specialties and function
The petroleum refining industry provides an expansive market for process measurement and control instrumentation and equipment, valves, and process analyzers. Having a basic understanding of the industry can help purveyors of instrumentation and equipment properly address customer needs, as well as recognize where opportunities may lie. Here is a summary of the types of plants and processes.

Petroleum refineries produce liquefied petroleum gases (LPG), motor gasoline, jet fuels, kerosene, distillate fuel oils, residual fuel oils, lubricants, asphalt (bitumen), and other products through distillation of crude oil or through re-distillation, cracking, or reforming of unfinished petroleum derivatives.

There are three basic types of refineries:
  • Topping refineries
  • Hydroskimming refineries
  • Upgrading refineries (also referred to as “conversion” or “complex” refineries). 
Topping refineries have a crude distillation column and produce naphtha and other intermediate products, but not gasoline. There are only a few topping refineries in the U.S., predominately in Alaska.

Hydroskimming refineries have mild conversion units such as hydrotreating units and/or reforming units to produce finished gasoline products, but they do not upgrade heavier components of the crude oil that exit near the bottom of the crude distillation column. Some topping/hydroskimming refineries specialize in processing heavy crude oils to produce asphalt.

The vast majority (75 to 80 percent) of the approximately 150 domestic US refineries are upgrading/conversion refineries. Upgrading/conversion refineries have cracking or coking operations to convert long-chain, high molecular weight hydrocarbons (“heavy distillates”) into smaller hydrocarbons that can be used to produce gasoline product (“light distillates”) and other higher value products and petrochemical feedstocks.

Figure 1 provides a simplified flow diagram of a typical refinery. The flow of intermediates between the processes will vary by refinery, and depends on the structure of the refinery, type of crude processes, as well as product mix.

The first process unit in nearly all refineries is the crude oil or “atmospheric” distillation unit. Different conversion processes are available using thermal or catalytic processes, e.g., delayed coking, catalytic cracking, or catalytic reforming, to produce the desired mix of products from the crude oil. The products may be treated to upgrade the product quality (e.g., sulfur removal using a hydrotreater).

Side processes that are used to condition inputs or produce hydrogen or by-products include crude conditioning (e.g., desalting), hydrogen production, power and steam production, and asphalt production. Lubricants and other specialized products may be produced at special locations.
