Small Capacity Expertise
Increasingly stringent state and federal environmental regulations have raised demand for smaller SRUs in a broader range of process plants. Principal Technology specializes in the turn-key modular units from 2-50 LTPD, affording us unique experience and capabilities to address specific issues of small capacity sulfur recovery, including:
- Heat Conservation / Temperature Management
- Equipment Sizing to maintain optimum process efficiency without sacrificing equipment operation and maintenance access
- Equipment Design to meet the specific needs of small capacity operations
We apply the technology that is the best solution for your operation, capacity, and the amount of sulfur generated and offer systems with high turndown ratios that can accommodate fluctuations in feeds for more flexible operation. Whatever the solution, Principal Technology scales the SRU equipment to meet the capacity demands of any refinery or Natural Gas plant while retaining operator access to all components for successful operation and easy maintenance.
