Intelligent monitoring for environmental safety at petrol stations
Needs and Challenges Seepage and leakage of oil from petrol stations can cause harm to the environment, especially to the soil and groundwater, which brings certain troubles to the operators of petrol stations and the society. In recent years, under the requirements of laws and regulations, many petrol stations have begun to carry out the renovation and use of seepage control measures such as double-layer tanks and double-layer pipes, and seepage and leakage monitoring equipment has also been adopted accordingly. However, there are some problems in this process. For example, at present in the petrol station, in addition to multiple monitoring equipment hanging on the wall at the same time -6S problem, more equipment also brings trouble to the user, operation and maintenance is not convenient. And currently installed leak detection equipment generally only real-time alarms, records can not be saved, that is, there is no traceability. Different leak detection products are not interoperable, each is an information island. Once the alarm occurs, it is only at the station end, which is equivalent to the "management blind spot". This status quo in the equipment investment and transformation projects have caused a considerable waste of investment. It can be said that the current tank system has monitoring facilities, but far from being able to meet the needs of information technology. The Solution As a professional service provider of petrol station underground tank monitoring systems, Oket has developed a one-stop, integrated leakage monitoring system solution. On the alarm side, Oket provides: the first way is the integration of level meter leakage detection, which uses the console to monitor the leakage detection sensors, including the online monitoring of oil and gas recovery; the second way is to use the integrated leakage detection alarm controller to monitor the leakage detection sensors. Customer Value A petrol station of PetroChina in Hubei: A PetroChina Wuhan petrol station has a total of 4 FF double-layer tanks. The station originally planned to use separate leakage alarms to monitor the leakage sensors, and the leakage sensor wiring harnesses have been laid indoors. After learning that AOKE liquid level instruments can integrate leakage sensors and achieve uploading and logging functions, the leakage alarms were canceled, and the level instruments were directly used to integrate the displays and alarms, which saves costs and improves the functionality. PetroChina Hebei petrol station: A PetroChina Hebei gas station uses 4 FF double-layer tanks and double-layer pipelines in the seepage control renovation, which requires four double-layer tank leakage sensors and four double-layer pipeline leakage sensors. According to the original idea of equipment installation, one double-layer tank leakage sensor and one double-layer pipeline leakage sensor need to be installed indoors. After communicating with Qingdao AOKE, the station adopted the solution of integrating double-layer tank and double-layer pipeline leakage detection. An integrated leak detector alarm is used to monitor 8 leak sensors at the same time. This solution for the future of the new retrofit station means a reduction of the various alarms and the multiple wiring now running from the indoor alarm to the tank sensors. Moreover, the use of liquid level meters for the centralized display and alarm of various leak detection and alarm devices means that the petrol station can be managed in a unified way for metering and environmental protection, which is more intuitive and convenient, and even more effective if it can be unified to output to a professional acoustic and visual alarm. If the old station is renovated, there is no need to break the ground, use the original Oket level instrument communication line to install leakage sensors, and the Oket level instrument can be shared with the console. The use of Okeet liquid level instrument console integrated leakage sensor has many advantages such as information integration, resource sharing, space cost savings, ease of use, integrated alarm, unified management and so on. On the sensor side, Qingdao Oket has a complete line of leakage sensors, including leakage sensors for FF double-layer tanks, SF double-layer tanks, impermeable pools, as well as leakage sensors for pipelines, manholes, and sumps of petrol dispensers. Qingdao AOKE Integrated Leak Detection Alarm not only monitors the leak detection sensors of eight double-deck tanks and pipelines at the same time, but also monitors the leak detection of manhole wells and petrol dispenser chassis. It has the functions of alarm (voice, light, text), recording, statistical analysis and uploading. Help customers achieve: more intensive product configuration; more neat and standardized design of petrol station; more economical investment cost; more convenient use; more effective operation and maintenance management; more intelligent petrol station informatisation;
