Example Process for Crude Petroleum Cleaning
- Step 1: Thorough Product Removal. To begin the railcar cleaning process, we meticulously remove any remaining product from the tank. Our cleaning procedure caters to various commodities, including food-grade and petroleum products. Typically, we initiate this step by opening the bottom outlet valve to drain out as much residual liquid as possible.
- Step 2: Ventilation for Safety. Next, we ensure the tank's safety by ventilating it through the top manway cover. While this ventilation method is suitable for most commodities, crude oil tank cars require alternative approaches. In such cases, we employ controlled ventilation to a flare system for safe vapor destruction until the vapors fall below the ignition threshold caused by sparks.
- Step 3: Technicians Scrape Residual Commodities. For crude cars, our skilled railcar technicians enter the tank to clean the heel. During this stage, another technician, known as a hole-watch, diligently monitors both the technician inside the tank and the vapor levels. The technician working inside the tank wears protective clothing, utilizes a vapor level monitor, employs a full-face air supply, and utilizes non-sparking scrapers.
- Step 4: Steam Cleaning for Optimal Results. Using our custom-made mobile boiler, we introduce steam into the tank for a duration of 2-4 hours, depending on the specific commodity. This steam treatment effectively loosens any remaining residuals, enabling thorough scraping once the railcar cools down.
- Step 5: Precise Pressure Washing. Following the second scraping, we employ a high-pressure washer combined with specialized soap to meticulously clean any lingering residuals present within the tank's metal or lining. This step ensures a comprehensive cleaning outcome.
- Step 6: Site Cleanup and Responsible Waste Disposal. As the final step, we diligently clean up the worksite and promptly remove all waste materials to an authorized disposal facility. Our commitment to environmental responsibility ensures proper waste management and disposal.
