Publication number: 20150276308Abstract: The invention relates to a process for the removal of CO2 from acid gas by cryogenic distillation performed in two steps. The feed mixture is first distilled at high pressure (at least 45 bar) in a first distillation column. The top product or a part thereof is then, after heating, subjected to a second distillation step at a lower pressure (lower than 45 bar). The top product of the second distillation step is methane of high purity (more than 99 mol.%). The bottom product of the second distillation step is recycled back to the first distillation column. The method according to the invention allows complete separation of methane also at higher level of acidic components, is economical and does not result in solid CO2 build-up, which is a common problem in cryogenic distillation.Type: ApplicationFiled: October 1, 2013Publication date: October 1, 2015Applicant: STAMICARBON B.V.

Patent number: 9000215Abstract: The invention relates to a method for urea production and to a urea production plant wherein ammonia emission in the final step of forming urea prills is reduced. In the method, the concentration of a urea solution is performed in at least three consecutive concentration steps and the residence time of urea melt leaving a last concentrator to the prilling tower is minimized. This can be achieved by placing the last concentrator in adjacency with a urea melt inlet of the prilling tower, such as above the prilling tower. In this way, the ammonia emission in the prilling tower can be reduced by as much as 50% compared to the conventional urea production plants. The invention further relates to a method for reducing ammonia emission in the prilling tower of an existing urea production plant.Type: GrantFiled: August 17, 2012Date of Patent: April 7, 2015Assignee: Stamicarbon B.V.Inventor: Johannes Henricus Mennen

Publication number: 20140299039Abstract: Disclosed is a method of transporting CO2 by ship for the purpose of storage in the ocean. The CO2 is transported at a temperature between ?25° C. and +25° C., and under a pressure that is sufficiently high for the CO2 to be in a liquid or supercritical state. The choice of temperature/pressure conditions for the CO2 enables the transport of CO2 one way to be effectively combined with transport of compressed natural gas (CNG) the other way. Ships can be used that have relatively cheap tubular containment equipment similar to the type normally used for CNG but with lower pressure and not subject to cyclic thermal and mechanical effects of pressurizing and depressurizing.Type: ApplicationFiled: August 17, 2012Publication date: October 9, 2014Applicant: STAMICARBON B.V.Inventor: Jacques François André Trollux
