- Meeting Refinery Standards
- Managing Multiple Waste Streams
- Hazardous, Non-Hazardous, & Biological Waste Processing
- Coker Injection
- Cement Kiln Preparation
By 2000, the principals of WM Dolphin Services had designed, built and were operating complete process facilities for five major Gulf Coast refineries. In addition to the Gulf Coast region, they were successfully operating in several refineries located in the West, Northeast and Midwest.
The processes designed by WM Dolphin Services principals were able to substantially reduce or eliminate hazardous waste streams going offsite. The solids produced from their centrifuge process created a dryer cake than previous technologies. This allowed the principals to provide optimum secondary treatment of the solids. In some cases, they were able to eliminate hazardous waste solids by utilizing coker injection and fuel blending of the centrifuge cake.
Non-Hazardous & Biological WWTP Streams
The principals found that many refineries were using belt presses for biological streams. The technology and design of the centrifuge allowed them to produce a dryer solid, reducing transportation and off-site disposal costs of non-hazardous biological streams. In some cases, they achieved up to 50% savings.
Hazardous Waste Streams
The principals’ ability to achieve significantly dryer solids than processes previously used for hazardous streams, resulted in facility efficiency and cost savings. They processed solids and produced a fuel ready for cement kilns, meeting the 8,000 btu per pound requirements. In addition, the principals designed a coker injection process for solids coming off the centrifuge and other areas within the refinery. The solids were prepared and injected into the quench cycle of the refinery cokers. This process gave refineries the opportunity to eliminate certain hazardous waste streams.
