A method for monitoring and controlling the polymerization in a polymerization vessel by using a camera viewing unit to (a) detect features of the polymer particles, or the particles' environment, (b) compare the features to pre-defined acceptable values of these features or the environment, and (c) if a variation from the pre-defined values is detected, act on process parameters to reduce or eliminate the variation.

Systems and methods include a computer-implemented method for managing crude oil demand at a crude oil processing plant. Real-time process data is received for the plant and includes quantitative values for conditions and operations at the plant. A multiple stabilizer oil flow control strategy is determined for crude oil stabilizer columns of the plant using the real-time process data. A targeted oil flow rate is determined for each stabilizer column using the strategy. The targeted oil flow rate provides a continuous and on-target crude oil supply to components of the plant in multiple operating scenarios. The on-target crude oil supply includes a range of oil flow volumes required for continuous operation. The plant is operated using the strategy, including maintaining, using the targeted oil flow rate for each stabilizer column, crude oil demand for different combinations of the crude oil stabilizer columns and multiple operating scenarios.

An objective of the present invention is to provide methods of producing a cyclic organic compound using a continuous stirred tank reactor(s) (CSTR), the methods being capable of achieving excellent impurity-suppressing effects (quality improvement), reduction in reaction-tank size, continuous production, and such. The present inventors conducted studies on cyclization reactions using a CSTR(s), which had not been conventionally used for cyclization reactions for cyclic compounds. As a result, the inventors have found that the present methods can achieve excellent impurity-suppressing effects (quality improvement), reduction in reaction-tank size, continuous production, and such, as compared with conventional cyclization methods. Furthermore, the present inventors have also found that the above-mentioned improvement effects can efficiently be achieved even in the production of cyclic peptides and heterocyclic compounds by applying simulation methods that had been conventionally used mainly at the fine chemicals plant level to the cyclization reactions of the present invention, thereby experimentally predicting the reaction rate of a cyclization reaction, and setting the flow volume (residence time), the concentrations of precursor and cyclic organic compound, and the temperature for the cyclization reaction and such which affect these conditions, in the cyclization reaction using a CSTR(s).

A process and system for maintaining optimum polymerization production in a loop polymerization reactor by continuously and periodically obtaining polymerization results, such as melt index (MI), production rate and ash content of the polymer produced, determining whether each of the results is within desired ranges, storing and averaging recently obtained results in a database within a reaction rate controller program, and when one of the results is out of the desired range modifying at least one reaction parameter set-point such as monomer concentration, catalyst feed rate and reactor temperature to drive any out-of-range polymerization result(s) toward the desired range for that result.

A process for maintaining an optimum polymerization process in a continuous loop polymerization reactor by driving a catalyst feed range set-point around a bad catalyst set-point range using a bad catalyst feed rate program to vary the catalyst feed rate for differing periods of time between previously determined good catalyst feed rates.

The product distribution from an oxidative dehydrogenation process can be altered by co-feeding different ratios of ethanol to steam, in the range of 0.01 to 0.50 ethanol:steam to an oxidative dehydrogenation reactor. Increasing the ethanol to steam ratio was found to: increase ethylene yield; decrease acetic acid yield; increase, or decrease, or cause no effect on CO or CO.sub.2 yield; and have negligible effect on ethane conversion. The feed ethanol is converted to carbonaceous products without negatively effecting the catalyst activity.
