Refining – Downstream
The principal hazards at refineries are fire and explosion. Refineries process a multitude of products with low flash points. Although systems and operating practices are designed to prevent such catastrophes, they can occur. Constant monitoring is therefore required. Safeguards include Fire and Gas warning systems, emergency procedures, and permit systems for any kind of hot or other potentially dangerous work. These requirements must be understood and followed by all workers.
Applications
ProDetec has access the the worlds best gas detectors for a wide range of industries. Whether the need is for a single application or multiple sites and areas, our durable gas monitoring solutions meet your unique industrial needs. We offer a broad range of gas detectors and controllers to satisfy international certification standards such as SIL (Safety Integrity Level), Marine and IECEx.
Detecting the right flame for the right application is critical when protecting your plant or process from Fire. Different fires require different technologies to accurately detect them, Whether it be UV, UV/IR, Single IR, IR3 or Intelligent Visual Flame technologies, ProDetec can offer expertise in selecting the correct detection method.
ProDetec can offer our customers innovative portable gas detectors that offer greater reliability, improved productivity, and better cost-efficiency to protect your workers from potential gas hazards. These gas detectors can be readily calibrated and tested on site with the aid of Automated Calibration and Bump Testing Stations
At ProDetec we can supply specialised gases and gas mixtures to meet various and specific requirements. We work with you to understand your application and analyse your consumption patterns. This way we can offer the correct cylinder size that maximises your efficiency while minimising costs.
Gas analysers based on TDLAS have been used for many industrial process control and emission monitoring applications and are well-accepted throughout multiple industries. The advantages of performing measurements directly in the process (in situ) include fast response, high selectivity and high sensitivity, which makes efficient process control possible. Furthermore, in situ measurements require little maintenance and thus lower operational expenditures.
Monitor your process water / process waste water for traces of oil by using an oil-in-water monitor. This ensures that process faults are detected at an early stage and/or environmental pollution resulting from exceeding the limits is avoided.
As has been documented in many journals and papers, the rim seal around the entire circumference of the floating roof tank presents a major fire hazard. Floating Storage Tanks usually contain highly flammable products which can potentially cause catastrophic fires. When the fire is not detected early it can cause significant loss of plant, down time of production and in severe situations even risk to life. These can have a large financial or environmental impact.
An Ultrasonic does not detect specific values of LEL or ppm, rather, it responds to the sound generated by escaping gas at ultrasonic frequencies. Such signals are generated when leakage occurs at sonic velocity; this requires a driving pressure of at least 2 barA. The detected sound is proportional to the leak rate (mass flow rate). In basic terms, the greater the leak rate (large leak), the greater the ultrasound emitted. Ultrasonic gas leak detectors complement traditional gas detection methods used in refineries, gas plants and offshore installations.
Wireless Gas Detection Systems are economically deployable in both permanent and temporary installations. Proprietary “self-healing mesh” technology operates at 2.4 GHZ and conforms to non licensed radio frequency appliance usage around the world. Wireless network integrity and security is accomplished using direct sequence spread spectrum DSSS programming topology. Wireless applications can be as simple as a single field device communicating with a host display or any number of field devices forming a network of subscribers.
Manual alarm call points are designed for the purpose of raising an alarm manually once verification of a fire or emergency condition exists, by operating the push button or break glass the alarm signal can be raised.
Measuring density of a sample is an important quality parameter of both raw materials and finished products. Various techniques enable the density of solid, viscous and liquid materials to be accurately determined e.g. metals, plastics, chemicals, lubricants and food.
Oxygen measurement in boiler feed water and in protective atmospheres
Optimize your process with a continuous concentration measurement of different substances in liquids. A typical application is to monitor waste water for traces of phenol. Effluent from mineral oil processing plants, plastics production etc. contain a high amount of phenol and have to be treated prior to being discharged into the environment.
This is mainly for thermal power houses, IGCC (Integrated coal Gasification Combined Cycle), etc. Air-fuel ratio control is very strict for some high-grade gas turbines so that gas turbines can be sustainably used with maximum combustion efficiency
