A vacuum generation system and method utilizes a dual-action piston-cylinder vacuum generation system to evacuate a vacuum storage. Saturated steam of higher than ambient pressure is inserted into a condensation cylinder with two chambers separated by a movable piston. Steam moves the piston to fill one chamber while expel gaseous content and condensate out of the other chamber. Steam is then condensed to a rough vacuum (RV) state by cooling. By repeated operations of inserting and condensing steam in each chamber alternatively, a sustained vacuum generation is achieved. A multi-level vacuum storage is also disclosed with a high vacuum (HV) storage placed inside a rough vacuum (RV) storage to reduce leakage as well as mechanical stresses. The vacuum generation system and method is extended for creating a prime mover or actuator to drive vacuum pumps maximizing thermal energy usage for increased vacuuming capacity.

A system and method for vacuum distillation and desalination contains integrated vacuum generation. Latent heat and a vacuum produced with steam condensation are used for distillation and desalination of liquid. The distillation and desalination system could comprise a spray evaporator and a condenser for receiving a feed stream for distillation or desalination. Produced are water flow condensate and concentrated liquid flow. A vacuum pump is actuated with condensation-induced dual-action piston-cylinder vacuum generation technology. The vacuum generator is configured to transfer latent heat from condensing steam vapor in its cylinder to the feed stream. Steam is also configured to transfer latent heat directly to the feed stream circulated through evaporators and condensers. A distillation and desalination method with active vacuuming and self-distillation in staggered multi-stage arrangement provides for efficient energy recovery. Use of multi-stage arrangement maximizes thermal energy usage for increased distillation capacity and applicability.

Modification of polymers containing an anhydride and uses thereof

With the coupling of an external field and aeration (or a flow of another gas), nanoparticles can be smoothly and vigorously fluidized. A magnetic force and/or pre-treatment may be employed with the fluidizing gas and, when coupled with a fluidizing medium, provide excellent means for achieving homogenous nanofluidization. The magnetic force interacts with non-fluidizing magnetic particles and helps to break channels as well as provide enough energy to disrupt the strong interparticle forces, thereby establishing an advantageous agglomerate size distribution. Enhanced fluidization is reflected by improved performance-related attributes. The fluidized nanoparticles may be coated, surface-treated and/or surface-modified in the fluidized state. In addition, the fluidized nanoparticles may participate in a reaction, either as a reactant or a catalyst, while in the fluidized state.
