BACKGROUND
PT Untung Bersama Sejahtera (UBS Gold) is a company engaged in the production of gold jewelry and precious metals. UBS Gold has a refinery department responsible for gold purification through several methods, including smelting and oven processing.
UBS Gold is currently making improvements and continuously developing innovations. One of these innovations is creating a healthy environment by keeping the air clean and fresh.
ISSUES
There are sources of air pollution in the production process.
In the refinery or smelting area, air pollution sources must be addressed. The following are some issues that need to be handled:
• Dust sources come from smoke emitted during the smelting process.
• The dust or pollutants to be managed will be collected and reprocessed because, according to the user, the dust still contains gold.
• Controlling high temperatures in the smelting room.
• The dust or pollutants to be managed contain acidic substances.
SOLUTION
The first step we take is analyzing the dust or pollutants that need to be handled. After conducting an analysis and collecting data, the next step is discussing with the user UBS Gold regarding the handling process based on the analysis and field data.
From the initial data, it was found that the existing Dust Collector System was not functioning optimally. Therefore, we designed the Installation and Dust Collector System based on calculations and analysis to ensure that pollutants or smoke emitted during the smelting process are properly managed.
We provide storage in the cyclone and Body Dust Collector to collect dust, which will be taken and reprocessed by UBS Gold.
The temperature in the smelting room reaches 90°C. Our approach to controlling or reducing the room temperature includes determining the suction speed of each hood suction and adding fresh air injection to the ducting installation.
After obtaining data showing that the dust or pollutants contain acid, we recommend appropriate and efficient materials to the user to ensure that the dust collector system and installation are not corrosive or abrasive, preventing financial losses for UBS Gold in air pollution control investments.
