20120285862 | METHOD FOR PRODUCING HIGH VCM COKE - A process and apparatus for improving the production of coke having a high volatile combustible material content are disclosed. The process may include, for example: heating a coker feedstock to a coking temperature to produce a heated coker feedstock; contacting the heated coker feedstock with a quench medium to reduce a temperature of the heated coker feedstock and produce a quenched feedstock; feeding the quenched feedstock to a coking drum; subjecting the quenched feedstock to thermal cracking in the coking drum to (a) crack a portion of the quenched feedstock to produce a cracked vapor product, and (b) produce a coke product having a volatile combustible material (VCM) concentration in the range from about 13% to about 50% by weight, as measured by ASTM D3175. | 11-15-2012 |

20090105446 | Method and Device For Producing Vacuum In the Production of Polyesters and Copolyesters - The invention relates to a method and a device for producing vacuum in the production of polyesters and copolyesters; unrectified vapors from at least one esterification or transesterification stage is preferably used as a driving medium in gas jet pumps for producing the vacuum in one or more polycondensation stages. | 04-23-2009 |
20090240007 | METHOD OF PRODUCING POLYESTERS - Polyesters such as polyethylene, polypropylene and polybutylene terephthalate are made from melts of precondensates of polyesters by first conducting vapors comprising precondensate components distributed in the form of an aerosol through a polycondensation reactor in which precondensate components are deposited on the reactor wall and in an outlet chamber of the reactor on a separator. Then the deposits are conducted to the unstirred discharge sump. Upper layers of the discharge sump are continuously recirculated in the stirred reactor area and thus subjected to reconversion and further polycondensation. | 09-24-2009 |
