Methods and apparatus for a short-term wash treatment used in a food-processing system are provided. One example control system includes an interface configured to receive one or more first sensor signals from the food-processing system; and a processing system coupled to the interface and configured to determine, based on the one or more first sensor signals, to reduce an intensity of the short-term wash treatment; generate a first control signal to cause an increase in a pH of the short-term wash treatment in response to the determination; and control application of the short-term wash treatment with the increased pH to a product in the food-processing system. Further the system may include a human machine interface (HMI) configured to display information from the processing system to a user.

The invention provides a method for enriching diluents with butane so as not to violate pre-defined limits for liquid hydrocarbon fuels with respect to density, volatility and low density hydrocarbon content.

A method for controlling the saturation level of gas in a liquid discharge includes obtaining temperature and pressure measurements of a solvent in a mixing vessel and obtaining a pressure measurement of a source feedstock in a feedstock tank, correlating the temperature and pressure measurements of the solvent to baseline data to generate a theoretical uptake rate for the source feedstock into the solvent and a theoretical flow rate of the source feedstock into the mixing vessel, and determining a required opening setting for a feedstock valve in the feedstock input line in order to achieve a desired liquid displacement in the mixing vessel. The method includes determining an uptake duration and achieving an uptake displacement equivalent to the reverse of the desired liquid displacement. The method includes generating a valve operating control law for how the feedstock valve should function in a cycle.
