Abstract: A process for purifying an inert gas stream from a transesterification reaction wherein a lower alkyl alcohol is released during the reaction is claimed. A second use of the process is to make a lower alkyl, e.g., methyl, esters of fatty acids through a transesterification reaction using gaseous alcohols as a source of the lower alkyl alcohols. The alcohol is diluted with nitrogen or other inert gas carrier and reacted with a fatty acid ester, preferably a triglyceride, to form the corresponding methyl or lower alkyl fatty acid ester.

Abstract: A hand holdable spray delivery system for dispensing a relatively viscous and/or solids laden liquid is provided. This spray delivery system includes a container adapted to house the liquid. A manually actuated pump device is mounted on the container. The pump device including an inlet passage, a pump chamber, and a discharge passage having a distal end connected in liquid communication so that the liquid is pumped from within the container, through the inlet passage, into the pump chamber and through the discharge passage upon manual actuation of the pump device. A slotted spray nozzle including a housing having an inlet side and an exit side is also included. The housing having an internal recess through the inlet side that terminates in an elongated orifice at the exit side.
