摘要:
Vessels can be become fouled due to normal operation thereof, for example, during lignocellulosic biomass hydrolysis, and the vessel will become inoperable unless the fouling is removed from the vessel. Accordingly, methods are disclosed herein for removing fouling substances from the interior surfaces of fouled pressurized vessels. The methods utilize a brief rapid change of pressure in the vessel. In some embodiments, the rapid pressure change is a decrease, and the rapid pressure change causes, for example, increased velocity of the fluid flowing in the vessel, flashing of a portion of the fluid to vapor, and removal of the fouling substance adhered to the interior surface of the vessel.

摘要:
This invention relates to compositions comprising cellulose particles and methods for making and using same. This invention also relates to compositions comprising a fluid and particles comprising cellulose. Thus, disclosed herein are methods of manufacture, isolation, purification, and handling of cellulose particles. Also disclosed are uses for cellulose particles as additives in leavened or leavenable food products, or in an emulsion or emulsifiable product, or as a suspension aid, or in a thickened composition, or in a meat or meat analog product, or in a personal care formulation, or in a beauty formulation, or in a cosmetic formulation, or in a skin care formulation. Also disclosed are uses for cellulose particles in subterranean treatment compositions. Also disclosed are uses for cellulose particles in metal working compositions, cutting compositions, and stamping compositions. Also disclosed herein are resuspendable particles comprising cellulose. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
