Electrical supply is imperative for larger facilities, especially for certain industries such as chemical, telecom, petrochemical and refineries.
Continuous and smooth power supply in these industries could be ensured by healthy Switchgear systems.
Switchgear plays a vital role in switching, controlling and protecting the fuses, circuit breakers and voltage switches etc. and ensures functional safety of the power system.
The switchgear room acts as a frontline defence for all the power system and its failure may lead to huge losses.
Thus, its protection also becomes essential. Often, the switchgear encounters temporary failures. The primary reason is insufficient protection against the airborne molecular contaminants (AMC) from the industrial surroundings as industrial sites or manufacturing plants are exposed to heavy air pollution and contamination.
The air contamination contributes to the poor health of the switchgear room equipment as it enhances corrosion, leads to sudden failure and disrupts the functioning of electronic equipment.
Also, the gaseous contaminants along with heat and moisture attack the metals and cause corrosion of metals.
The most common gases that cause corrosion of electronic equipment are Sulphur Dioxide (SO2) and Hydrogen Sulphide (H2S). The major sources of these gases are industrial units that use coal or oil, petroleum refineries, cement manufacturing, metal processing, paper & pulp manufacturing, copper smelting, textile production, chemical manufacturing and waste disposal etc.
Bry-Air Gas Phase Filtration System is ideal for removing airborne molecular gaseous contaminants, which is primarily responsible for corrosion in switchgear.
Bry-Air helps in reducing downtime by removing corrosive gases through the process of adsorption and chemisorption.
The system is designed to maintain the ISA Standard 71.04-2013, IEC Standard and environmental standards, which are followed by most electrical equipment manufacturers.
Bry-Air is One Stop Shop for Gas Phase Filtration products and services.
P. S. Switchgear can also fail due to short circuit and it can be avoided by controlling the moisture level in the room in conjunction with an air-conditioner. The simplest and the most cost-effective solution to control moisture level is to install a Bry-Air Dehumidifier.
Fly ash being very hygroscopic tends to absorb the moisture from the surrounding air which results in lumping and caking.
Eagle Cement Corporation is a fully integrated Filipino-owned company manufacturing, marketing, sale and distribution of high-quality cement under the brands Advance Type 1P, Exceed Type 1P and Strongcem Type 1.
Their primary cements production facility located in San Ildefonso, Bulacan, which is the single largest cement manufacturing plant in the Philippines in terms of production quantity. Fly Ash is one the major elements/ingredients of their cement. Since, fly ash is highly hygroscopic, it tends to absorb the moisture from the surrounding air which results in lumping. Moreover, once that happens, it cannot be used for manufacturing cement.
The fly ash is transferred from the inbound trucks (from Coal Thermal Power Plant or Steel Plant) to the fly-ash separator, where it is separated from the residual un-burnt coal. After separation, it is transferred to the cement manufacturing plant.
This process is managed with fresh air being pre-cooled and dehumidified at normal atmospheric pressure. Thereafter, high static pressure fans force the dry air to carry the fly ash into the separator pneumatically.
To ensure the fly ash does not absorb moisture during conveying, Eagle Cements contacted the Airgineers at Bry-Air Philippines. The Airgineers recommended that the dew point of the air reduced to -30 °C. The dew point was accomplished by a customised dehumidification system, which controlled the absolute humidity. Bry-Air Dehumidification system ensures smooth production, conveying and processing.
