20140328722 | METHOD AND APPARATUS FOR PREPARING POLYMER BEADS OF UNIFORM PARTICLE SIZE BY SUSPENSION POLYMERISATION - Monomer solution and liquid solution immiscible with the monomers in the monomer solution are cocurrently jetted upwardly in a pulsating manner in a reaction vessel. Monomer droplets are allowed to rise up in a controlled and smooth manner under the dynamic forces exerted by differential flow rate and differential pressure between the monomer and liquid solutions and the differential densities between the monomer and liquid solutions without causing coalescence, agglomeration and breakup of the monomer droplets and to stabilize by partial polymerization of the droplets at 50-60° C. The monomer droplets flow out horizontally into a polymerization reactor and get polymerized in the polymerization reactor under agitation at 80-85° C. The polymer beads are dried at 80-100° C. and sieved. | 11-06-2014 |

20130269373 | HYBRID ABSORPTION-COMPRESSION CHILLER - The present invention envisages a hybrid absorption-compression chiller comprising: a vapor-compression system providing refrigeration effect in a primary evaporator ( | 10-17-2013 |
20120324925 | TRIPLE-EFFECT VAPOR ABSORPTION REFRIGERATION SYSTEM - A triple-effect vapor absorption refrigeration system is disclosed. The system comprises a high temperature generator, a medium temperature generator, and a low temperature generator, for concentrating a dilute Li—Br solution from an absorber, through a flow path from the high temperature generator to the low temperature generator via the medium temperature generator. In the system maximum Li—Br solution temperature and maximum Li—Br solution concentration does not occur simultaneously, hence, Li—Br corrosion rate is reduced and minimum non-condensable gases are generated, this helps in maintaining vacuum during operation thus providing a smoother operation. | 12-27-2012 |
20110225991 | HIGH EFFICIENCY DOUBLE-EFFECT CHILLER HEATER APPARATUS - The absorption chiller-heater apparatus of present invention utilizes a portion of direct heat, used to heat water, for providing the refrigeration effect. The external heat input required for providing refrigeration is minimal; hence, the efficiency of the apparatus is increased by 30-40% over the conventional systems. Further, as the quantum of the external heat source required for a new cycle is reduced, the size of the high temperature generator required, is smaller, which results in lower capital costs. The apparatus provides chilled water which can be used for various industrial purposes. The absorption chiller-heater reduces CO | 09-22-2011 |
20100270005 | CHILLER-HEAT PUMP - An apparatus for providing heating and/or refrigeration effect and a method thereof is disclosed which provides simultaneous heating and refrigeration, only heating or only refrigeration, using a double-effect vapor absorption cycle or a single-effect vapor absorption cycle. The present invention comprises providing a heat input to an absorbent in a generator to obtain a concentrated absorbent which is fed to a set of absorbers which are located in co-operation with a set of evaporators provided with a condensed refrigerant, to obtain heating and/or refrigeration effect. The heat/energy used during the process is recovered by a plurality of heat exchangers such that the wastage of energy and utilities is minimized. The present invention substantially reduces the CO | 10-28-2010 |
