NEW CRYSTALLISATION LINE LAUNCHED[04.03.2021]
Shchekinoazot is completing the commissioning of a new line in the caprolactam crystallisation department.
The company is implementing investment projects and building high-tech production facilities in accordance with its long-term development strategy. It is also simultaneously carrying out other programmes, such as upgrading the production of caprolactam and cyclohexanone.
A number of important technical projects have been realised in the production shops over the past few years. In particular, Shchekinoazot has set up a separator in the cyclohexanone shop to improve the separation of oxidation products and has installed a cyclohexane purification column. The hydroxylamine sulfate shop, which has for many years limited the load and output of the caprolactam shop and the entire production facility, received a new syngas reactor with a new LaMont boiler and frequency converters, making it possible to increase the production of hydroxylamine sulphate. Stage 300 cascade reactors are being gradually replaced with higher volume units, which also contributes to an increase in production. As a result, production will reach a stable maximum capacity load of 168 tons of caprolactam per day by 2020.
Investments in these activities result in the stability of production loads and the high quality of the finished product.
Demand for products is largely determined by its packaging.
Due to the increased consumer requirements for packaging, Shchekinoazot OJSC decided to replace one of its packaging and filling lines. The automated filling and packaging line was made by the German company Möllers, and crystallisation equipment was manufactured in India.
The new caprolactam crystallisation, packaging and filling line was launched in December 2020. Prior to that, the team of PSK Shchekinoazot LLC put a huge effort into preparing the site, dismantling the old packaging line and floors and strengthening the foundations. It is not the first time that qualified PSK specialists perform the most difficult tasks at the production site when we need to mount new equipment in an existing workshop without stopping or damaging the operating line. This time, they had to dismantle the walls and remove the floor slabs to put the crystalliser in position. The production of crystalline caprolactam in the shop continued during the works.
A special perforation, which is automatically added to bag corners for air release during the manufacturing process, provides a noticeable increase in quality and makes sure the sensitive and demanding crystals reach the consumers without losing any of its properties.
Today, the new line still operates in the run-in mode in order to select and set up the optimal modes, film and bag and pallet sizes.
The employees are familiarising themselves with all the nuances of the new equipment. They note a significant improvement over the old line thanks to the electronics, quick diagnostics and prompt troubleshooting. Packaging quality has noticeably improved and the pallets are stacked evenly and symmetrically, which is very important during the loading and unloading to ensure the safety of packages and the product itself.
Product quality and customer satisfaction are always used to determine the manufacturer's success in any industry, including the chemical one, and their place in the domestic and global markets.
Today, the new line has an output capacity of 300 bags of crystals per hour, which is in line with the maximum production load. However, according to experts, the new crystallisation and packaging line will be able to increase its capacity by about one and a half times if caprolactam production increases. There is a reserve capacity.
The old line is still in operation, but it will soon stop and will be used only in case of need, during the maintenance of the new line. Consumers are already getting the products made at the new line. The manufacturer is waiting for their feedback on the new quality of crystals and their packaging.
