Abstract: A movable cell incubator contains: a body, a first lid, a second lid and an electric control unit. The body includes a first internal space, a refrigeration room, and an airtight culture room. The first lid airtightly covers the culture room, the second lid airtightly covers the refrigeration room, and the control unit includes a microprocessor, a power module, a digital/analog conversion module defined between a microprocessor and the power module, a heating module controlling temperature of the culture room, a cooling module supplying cold source to the refrigeration room, a peristaltic pump module, a flow sensing module, a CO2 detective supply module supplying CO2 to the culture room, and a setting display module exposing and fixed on the first lid, with the peristaltic pump module aseptically connected between cell culture media and cell culture bag by multiple conveying tubes.

Abstract: A methanol carbonylation system 10 includes an absorber tower 75 adapted for receiving a vent gas stream and removing methyl iodide therefrom with a scrubber solvent, the absorber tower being coupled to first and second scrubber solvent sources 16, 56 which are capable of supplying different first and second scrubber solvents. A switching system including valves 90, 92, 94, 96, 98 alternatively provides first or second scrubber solvents to the absorber tower and returns the used solvent and sorbed material to the carbonylation system to accommodate different operating modes.

Abstract: A method is disclosed for controlling a methanol carbonylation process for producing acetic acid. The method includes the steps of monitoring the rate of production of the acetic acid; reducing the production rate in response to a change in a process condition or a process equipment condition; after the production rate is reduced, controlling the process at the reduced production rate; and increasing the production rate after the condition change has been addressed until at least the production rate returns to a normal operating range; wherein during at least one of the steps of reducing the production rate, controlling the process at the reduced production rate, and increasing the production rate until the production rate returns to a normal operating range, the process is controlled by nonlinear multivariable control based on a model of the process.
