Zero Emission Solutions For Mechanical Seals On Light Hydrocarbons

Lecturepg. 69While simple mechanical seals will continue to improve in performance and be extensively used, there are occasions where zero leakage is required, and where the currently recognized option is the glandless pump, which imposes other limitations. Similarly, tandem and double mechanical seals, which can achieve zero emission levels, may not be acceptable based on cost and/or space requirements. The actual performance in operating plant of conventional and enhanced systems is reviewed. The conception, design, development, and tests of innovative new systems is described. These systems are designed to achieve zero emission levels without the expense and inconvenience of glandless pumps
