Optimal Campaign Planning/Scheduling of Multipurpose Batch

A general mathematical formulation for multiple campaign planning/scheduling of multipurpose batch/semicontinuous plants is presented. In contrast to sequential approaches, a single-level formulation is developed encompassing both overall planning considerations pertaining to the campaign structure and scheduling constraints descri the detailed operation of the plant during each campaign.

Synthesis of Zero Effluent Multipurpose Batch Processes

an operation. In essence, an optimal design of a batch processing plant is determined by considering the scheduling of operations in the synthesis phase. The mathematically based method presented in this paper deals with the synthesis of a batch plant operating in the fashion mentioned above. The method determines the optimal size and number of

Crystallization & Precipitation | Definition, Steps, Equipment

Crystallization, or crystallisation, is the process of atoms or molecules arranging into a well-defined, rigid crystal lattice in order to minimize their energetic state. The smallest entity of crystal lattice is called a unit cell, which can accept atoms or molecules to grow a macroscopic crystal. During crystallization, atoms and molecules

Compressed Air Basics | AIChE

Various cooling water sources are found in industrial plants. Where city water is used, the quality of the water is generally good, but in some areas, treatment for hardness may be needed to avoid fouling of cooling surfaces. Water analysis should be conducted to determine any treatment needs (3). Motor and air-end bearings.

Model predictive control - Wikipedia

Model predictive control (MPC) is an advanced method of process control that is used to control a process while satisfying a set of constraints. It has been in use in the process industries in chemical plants and oil refineries since the 1980s. In recent years it has also been used in power system balancing models and in power electronics. Model predictive controllers rely on dynamic models of

Bioreactor - Wikipedia

A bioreactor refers to any manufactured device or system that supports a biologically active environment. In one case, a bioreactor is a vessel in which a chemical process is carried out which involves organisms or biochemically active substances derived from such organisms. This process can either be aerobic or anaerobic.These bioreactors are commonly cylindrical, ranging in size from litres

Planning and scheduling of industrial supply chains with

As final solution the models provide two levels of information: (1) the optimal aggregated plan for a given planning time domain (e.g. 6 months) and (2) its concretization at the scheduling level (e.g. 1 week) where detailed information on supply, production, inventory, transportation and recovery of products is optimized based on a pre-defined

Deodorization - AOCS

Overall, batch deodorization has become less attractive because of its higher operating cost (higher steam consumption, low heat recovery) and longer processing time. However, for small-capacity plants (<50 tons/day) or plants that process smaller batches of varying quality (e.g. fish oil refiners), a batch deodorizer is still the best option.
