Explosion proof street lamps in the refinery lighting applications – safety, energy saving and intelligent comprehensive solutions

First. Refinery Lighting Special Needs and Challenges

Flammable and explosive gases such as hydrogen, methane, hydrogen sulfide, etc. are commonly found in the refinery environment, accompanied by high temperature, corrosive substances and dust.

Traditional lighting equipment is easy due to electric sparks or surface heat triggered by an explosion, and Explosion proof street lamps with its intrinsic safety design, into a necessary choice to protect the safety of the plant.

For example, an oil refinery due to the use of ordinary lamps and lanterns lead to arc ignition gas accident rate had been as high as 12%, and the introduction of Explosion proof street lamps, the accident rate dropped to zero.

Second, Explosion proof street lamps in the refinery core advantages

1. Explosion proof performance and safety certification Explosion proof street lamps using Explosion proof structure [such as Exd IIC T4 Gb guidelines], approved double protection mechanism:

One is to limit the internal arc and spark escape.

The second is to control the shell surface temperature below the ignition point of the gas [such as T4 group ≤ 135 ℃], to ensure stable operation in the refinery Ⅰ, Ⅱ dangerous environment.

2. Energy efficient and long life energy consumption comparison: 100W LED Explosion proof street lamps, for example, its luminous flux of up to 12,000 lumens, compared with the traditional 400W high-pressure sodium lamps, energy consumption reduced by 75%, single-lamp annual power savings of more than 2000 degrees.

3. Lifespan advantage: the use of solid-state LED light source, life expectancy of more than 50,000 hours, reducing the loss of downtime due to frequent replacement, the comprehensive maintenance costs by 60%.

4. Environmental adaptability and enhanced corrosion-resistant design: aluminium alloy shell combined with epoxy resin spray coating process, salt spray resistance test over 1000 hours, suitable for coastal refineries with high salt spray environment.

5. Wide temperature range operation: It can support extreme temperatures from -40℃ to +60℃, which meets the needs of desert oilfields and refineries in extremely cold areas.

6. Intelligent control and flexible deployment of approved Internet of Things technology, Explosion proof street lamps can be implemented remote dimming, fault warning and energy consumption statistics.

For example, a refinery base to approve intelligent systems will be low at night to adjust the operating hours of illumination to 50%, the annual energy-saving rate increased by 30%.

Third. Typical scenarios and solutions for oil refineries

1. Tank area and pipeline lighting: 250W high-power Explosion proof floodlamps, covering a radius of 30 metres, luminous efficacy ≥ 140 lm/W, to ensure the safety of night inspection. 2.

2. Explosion proof level: ExdⅡCT6 standard, adapt to hydrogen and other high-risk gas environment.

3. Combined Explosion proof street lamp for factory road and loading/unloading area: modular design [such as HBND-B807] helps to combine multiple light sources, with a light distribution angle up to 120°, which reduces the number of luminaires and improves the uniformity.

4. Installation methods: ceiling-mounted, wall-mounted and boom-type flexible to adapt to complex terrain, reducing construction difficulties.

Case reference: a 10-million-ton oil refinery will replace 400 sets of traditional metal halide lamps with 120W LED Explosion proof street lamps, the annual electricity bill savings of more than 800,000 yuan, the payback period of only 1.5 years.

Fourth, selection and installation specifications

Selection points priority to choose the approved ISO9001 certification and Explosion proof qualification enterprise products.

Heat dissipation structure needs to be improved [such as copper-aluminium composite radiator], to avoid high temperatures leading to light degradation.

Installation and maintenance cables should wear Explosion proof flexible tubes, junction box sealing level of IP54.

Regularly clean up the lamp surface oil, check the blockage of the heat sink to ensure temperature control performance.

Fifth. Future momentum: intelligent and modular upgrade

Emergency linkage system: linkage with gas detector, automatically enhance the lighting and trigger the sound and light alarm when leaking.

Modular design: help high-speed replacement of damaged parts, reduce maintenance time by 70%.

Lighting efficiency breakthrough: Next generation LED technology improves light efficiency to 200 lm/W, further reducing energy consumption.

FAQ: Explosion proof street light common problems

Q1：How to determine the Explosion proof grade of Explosion proof street lamps in oil refineries?

A: According to the type of gas [such as Ⅱ C class corresponds to hydrogen] and temperature group [such as T6 for the highest standard] selection, advocating that the professional engineers to assess the environment to determine.

Q2: Is Explosion proof street light applicable in offshore oil refining platform?

A: Yes. High quality products are approved with IP66 protection and salt spray resistance treatment, which can withstand high humidity and salt spray corrosion.

Q3: Does the intelligent control system increase the cost?

A: The initial investment increases about 15%, but approved energy saving and reducing manual inspection, the extra cost can be recovered in 2 years.
