“…Figure 7 shows the design of a new steam supply from the reduction station V1 to the new reduction stations V2 and V3. It consists of isolations valves (3, 5, 8), a steam separator (4), steam strainers (6, 36), a ball oat steam trap (7), a ow meter (35), ange connections (32,34) and a exible anchoring (37). Figure 8 then shows a visualization of the new reduction stations V2 and V3 design, which will be fed by steam through the steam supply from the reduction station V1 (Fig.…”

“…Management of change in real operation in actual plant (Wang et al, 2020), however, is a very investment demanding process, and it is therefore necessary to take into consideration that such a fundamental change is planned in range of years (S. Zhu et al, 2022), rather decades. On the other hand, it is possible to modify currently installed steam production technology (Khaleel et al, 2022) to make it more e cient (Katla et al, 2020, Mondal et al, 2020.…”

The demand for high-strength grade fibers and consumption of viscose fibers shows increasing tendency and growing trends in use of this product. Regenerated cellulose-based fibers of various properties are produced in order to meet all needs using new production technologies developed especially in recent years. One of the key processes in fiber spinning is continuous drying before final winding on spools. The manufacturing methods used for viscose fibers allows production of various types, parameters and specifications of fibers. It is therefore increasingly necessary to implement and standardize a drying concept to stabilize subprocess in a continuous production manufacturing as much as possible within the desired parameters of the final product. These activities and methods embody concepts for production of the highest quality fibers suitable to both producers and users. Currently, the concept of drying viscose fibers in a continuous production process is a problem that affects its final shape and quality properties such as commercial weight, linear density and tensile properties of all products and lengths for staple fibers as well as shrinkage and twisting for yarns of fibers. Due to that, development of technology enabling maximum stabilization of the drying process to achieve long-term sustainable final fiber quality parameters was adopted as a strategic project, including incorporation of efficient solutions for the overall energy intensity of this process in order to reduce the manufacturing carbon footprint by 23.81%. The production of viscose fibers and the project also aims to achieve significant energy savings up to 24 509.9 GJ·year-1.
