The present disclosure is directed to methods, approaches, devices, equipment, and systems for minimizing or reducing contamination in facilities implementing fermentation or distillation processes. In embodiments, the facility is a biofuel plant that produces fermentation product such as product alcohol like butanol. In some embodiments, the methods, approaches, devices, equipment, and systems are operable to implement clean in place contamination (CIP) mitigation techniques that can also include sterilize in place (SIP) mitigation techniques to decontaminate equipment including surfaces of the equipment that come in contact with materials used in the production of product alcohols. Other cleaning and contamination minimizing techniques are also described.

Contamination mitigation

The present invention relates to processes and systems for the production of fermentative products such as ethanol and butanol. The present invention also provides methods for separating feed stream components for improved biomass processing productivity.

Processes and systems for the production of alcohols

This invention relates to an improved cake-filtration solid-liquid separation process wherein the improvement comprises simultaneously subjecting the solid-liquid mixture to a homogeneous magnetic field, a magnetic field gradient or both and cake-filtration to accomplish separation.

Magnetic field enhanced cake-filtration solid-liquid separations

This invention relates to apparatus for carrying out continuous or batch centrifugation solid-liquid separation processes in which the solid-liquid mixture is subjected to magnetic field gradients and centrifugation.

Apparatus for magnetic field gradient enhanced centrifugation

This invention relates to various apparatus for carrying out cake-filtration solid-liquid separation processes in which the solid-liquid mixture is subjected to a homogeneous magnetic field, a magnetic field gradient or both and cake-filtration.

Apparatus for magnetic field and magnetic gradient enhanced filtration

This invention relates to a continuous or batch centrifugation solid-liquid separation process comprising simultaneously subjecting the solid-liquid mixture to localized magnetic field gradients and the centrifugation and to improved centrifugation solid-liquid separation processes wherein the improvement comprises simultaneously subjecting the solid-liquid mixture to a homogeneous magnetic field, a magnetic field gradient or both prior to and/or during the centrifugation.

Magnetic field and field gradient enhanced centrifugation solid-liquid separations

The present invention relates to fabrics that can be used in the manufacture of paper. The fabrics preferably have at least three regions of fabric with specified distributions of pore sizes. The fabrics disclosed herein are an effective alternative to conventional dewatering fabrics for removing water from the incipient paper, which can provide energy cost savings in subsequent elevated temperature drying steps.
