In December 2019 a one-stage butane dehydrogenation (OSBD) production unit of PJSC Nizhnekamskneftekhim Butyl Rubber Plant celebrates its 45th anniversary. During this period, divinyl and butane-butylene fractions were produced in the volume of more than 2.7 million tons each. For a company, a one-stage butane dehydrogenation production unit is an important source of raw materials that manufactures the main products necessary for the production of SKDN, SKDL and BR.
A one-stage butane dehydrogenation production unit is a unique large-capacity facility with certain process features. The unit consist of two workshops – one-stage butane dehydrogenation production unit -2 and one-stage butane dehydrogenation production unit -10, producing up to 320 tonnes of divinyl per day – the biggest volume of divinyl against other PJSC Nizhnekamskneftekhim production plants.
As part of major overhaul in 2019, a large-scale equipment replacement was carried out at a one-stage butane dehydrogenation production unit. A 108 ton reactor was replaced at the workshop No. 1319, OSBD-2. As well, lining of all eight reactors was completely replaced, which made it possible to protect their surfaces from thermal damage, reduce heat loss to the atmosphere, and increase the service life of the reactors. Some process equipment was retrofitted, including steam turbines and compressors; furnace coils and recovery boiler tubes were replaced, the catalyst was reloaded on eight dehydrogenation reactors at the OSBD-2 workshop.
Plant employees also implement environmental and energy conservation measures, work on improving technologies and equipment. Compared with the design values, the volume of substances burned in a flare unit has been significantly reduced.
PJSC Nizhnekamskneftekhim completed the retrofitting of control centres at the Production Directorate and the Chief Power Engineer Division.
Established in 1970, the company's master control center constantly improved its functions. Modern means of communication and control were introduced here with the construction and start-up of new production facilities and plants, including a production monitoring system (video wall).
In order to create an operation control station capable of performing new tasks, it was equipped with the most up-to-date facilities for communications and control of production processes. To monitor the effluents, an interactive map was developed to see the quality of wastewater online and take operational measures if necessary.
Particular attention was paid to improving the production monitoring system: video screens (video walls) were installed that allow online monitoring of production processes in the company’s divisions. For this purpose, the company's specialists developed the software necessary for the stable and synchronous operation of a large number of different programs.
Following the work done, the operations controllers of Nizhnekamskneftekhim got the opportunity to view the video walls of the production units. In the round-the-clock mode, they monitor the movement of feedstock flows, finished products, information on shipment and a lot more. Moreover, mnemonic diagrams of the ethylene plant process units were created and optimised for the upgraded production monitoring system. Similar work is now being carried out at other company’s plants.
During the modernization process, the area of the premises was increased, new equipment for operational dispatch communication was purchased and installed, and the air conditioning system was replaced.
This modernization made it possible to improve the condition of employees' workplaces, increase the information content of existing production monitoring systems, that will undoubtedly increase the efficiency of PJSC Nizhnekamskneftekhim master control centers.
