Process for the preparation of a starch ester, in particular a starch acetate, wherein a starch-based feedstock is reacted with an organic carboxylic acid anhydride in the presence of a catalyst. The reaction of the starch-based feedstock and the anhydride is performed at an excess pressure of about 0.1 to 50 bar in an essentially anhydrous medium containing 10% by weight of water at the most. As catalyst, sodium acetate, sodium hydroxide or sulphuric acid is used, and as the reaction medium, acetic acid or excess acetanhydride is used. By means of the invention, the duration of the esterification reaction can be significantly shortened, the separation of the product can be facilitated, and the recirculation of the waste solutions can be rendered more efficient.

A method of regenerating N-Methyl-D-glu-camine-functional resin that has been used for boron-removal uses a closed recirculating loop for treating the conjugate acid salt of the N-Methyl-D-glucamine functionality of the resin. The new method reduces rinse water demand and improves pH control in a water treatment system. The new method can be used to improve the performance of boron-selective resins in stand-alone systems or as a second stage in a reverse osmosis seawater desalination system. The regeneration method is useful in any application where weakly basic anion exchange resin in the conjugate acid salt form is to be regenerated (neutralized) by alkaline treatment. Possible end use applications are in drinking water processing, agricultural water treatment, sweetener production, waste water processing, mining hydrometallurgy, and condensate polishing.

A power generation system for generating electricity using a steam turbine engine that yields high-pressure steam has been developed using a preferably non-toxic coolant circulating in a closed loop that passes through a rock and earth aquifer, for directly and / or indirectly condensing the low-pressure steam from the low-pressure side of the steam turbine into a liquid phase for re-circulation to the steam turbine, whereby the coolant acts to dissipate the heat from the low-pressure steam through the aquifer to the rock and earth encasing the aquifer. In one embodiment a containment shroud is employed to recycle condensing water utilized to condense the condensing vapor emitted from a steam condenser. In a second embodiment a sealed steam condenser is utilized through which the low-pressure steam passes, and water (or other suitable fluid) from an enclosed condensing water reservoir, through which the coolant is circulated, is employed to condense the low-pressure steam in the steam condenser. In yet another embodiment, the coolant is introduced directly into the steam condenser. In a further embodiment an intermediate refrigeration system pump is employed together with the coolant, for condensing the low-pressure steam.

A tubular pipe lining material impregnated with a thermosetting resin is inserted into a pipeline and made to expand and press against an inner peripheral surface thereof. Hot water or steam is sprayed onto the pipe lining material to cure the thermosetting resin impregnated therein. Hot water that has accumulated in a bottom part of the pipe lining material is pumped out to an external location by a pump and cooled by a cooling device to generate cool water, which is then sprayed via a hose onto the cured pipe lining material to thereby cool the heated pipe lining material. This enables the thermally cured pipeline lining material to be reliably cooled and rendering a water truck unnecessary that is required at a construction site to supply additional cooling water.
