New pilot-operated relief valve for enhanced storage tank reliability and protection
Emerson has introduced the Fisher™ 63EGLP-16 pilot-operated relief valve (FIG. 1) for installation on pressurized bullet tanks used to store liquid propane and anhydrous ammonia. This type of pressure relief valve (PRV) is typically installed on tanks fabricated by original equipment manufacturers (OEMs) that provide them to end users, engineering firms or contractor customers. The new valve is certified under UL132 and American Society of Mechanical Engineers (ASME) Section VIII.
With a pre-installed national pipe tapered (NPT) thread standard 2-in. male hex nipple, this new product serves the need for a solution with a 2-in. connection that provides the same benefit as traditional multi-ported valves, but with simplified installation and maintenance. For this application, the PRV must be connected directly to the tank, with no isolation valve between the tank and the PRV. This National Fire Protection Association (NFPA) 58 code requirement presents challenges when testing the PRV while the tank is pressurized and in operation.
The Fisher 63EGLP pilot-operated relief valve addresses this and other issues because it is the only pilot-operated relief valve on the market designed specifically for this type of service. Operation is implemented with a dual pilot array, providing redundancy and allowing for removal of one pilot for testing while the other is operational.
Because this is a critical safety-related application, reliable operation over a long lifecycle is needed. This requirement is met by the 2-in. PRV because it is similar in design to the Fisher 63EGLP 4-in. CL300 model, which has been proven in use over the past 10 yr.

Effective monitoring of oil in water for petrochemistry
Petrochemistry faces the challenge of effectively monitoring oil residues in water. Contamination of water sources with oil can have significant environmental impacts and lead to costly damages. In facilities that use oil for the production of bioenergy, lubricants and edible oils, the risks of leaks and environmental pollution are constant.
Conventional oil-in-water (OiW) analyzers on the market measure indirectly and rely on secondary oil properties. This poses a challenge in choosing the right analyzer, as the consistency, composition and origin of the oil can influence the analytical result. This becomes particularly critical when the OiW composition changes over time and includes various unknown oil types.
To overcome these challenges, Process Insights offers an effective solution for petrochemistry. The QuickTOCultra™ analyzer (FIG. 4) measures directly and quantifies all types of oil, fat and lubricants, regardless of their origin.
