Aug 01, 1987 Cement manufacturing process is now operated with the aid of various control systems, such as raw meal composition control, kiln control and mill control. Those systems have greatly contributed to achieve uniformity of quality as well as cost reduction of cement. But from the viewpoint of optimization of cement manufacturing operation, it is desirable to build an integrated control system, which supervises and directs each control …

This paper focuses on modelling and solving the ingredient ratio optimization problem in cement raw material blending process. A general nonlinear time-varying (G-NLTV) model is established for cement raw material blending process via considering chemical composition, feed flow fluctuation, and various craft and production constraints. Different objective functions are presented to acquire ...

Fulcrum technology improves stimulation efficiency by helping keep fracturing fluid and hydraulic pressure in the intended reservoir zone. If your fracturing fluid migrates through channels behind the casing into a different zone, the targeted reservoir doesn’t receive its intended treatment. That means you wasted a frac, and the stage doesn ...
Sep 16, 2020 Moreover, while the cement industry has seen major advancements in IT infrastructure and operational technology over the past two decades, return has been below expectations. The efficacy of new enterprise-resource-planning systems, process-optimization tools, and even predictive maintenance has lagged behind due to change-management challenges ...

Sep 16, 2019 The process looks a bit like shaking a snow-globe, as it produces a flurry of suspended white particles inside the glass container as the lime precipitates out of the solution. While the technology is simple and could, in principle, be easily scaled up, a typical cement plant today produces about 700,000 tons of the material per year.

Cement manufacturing is a complex and energy-intensive process. A key stage in this process is the conversion of ground raw materials (CaCO 3, clay and/or shale) into clinker (synthetic cementitious minerals) in the kiln. A typical operation uses kiln exhaust gases to preheat the raw materials before they enter the kiln. Further

The optimization may also account for constraints on the process inputs and the process outputs. Finally, the first instance for each calculated future control signal is applied to the process. It is worth noting that normally the objective function is a weighted sum of deviations in the plant outputs and in the control signal increments.
