摘要： Disclosed is a urea plant wherein, in deviation from conventional plants, a high-pressure synthesis section is operated with two different pressures. The synthesis section comprises a reactor, which is operated under a first high pressure. The synthesis section also comprises a stripper and a condenser, both operated at substantially the same second high pressure. In accordance with the invention, the first pressure is substantially higher than the second pressure. The disclosed plant particularly comprises a compression unit capable of converting a pressure difference into work, or more specifically, mechanical energy for compression. This compression unit is positioned between a liquid outlet of the condenser and a liquid inlet of the reactor, and in fluid communication therewith. In order to make use of a pressure drop (expansion as a result of a liquid being depressurized), said compression unit is configured to obtain compression energy from one or more events in the urea production process ( i.e. , at one or more points in the urea production plant), at which a loss of energy occurs, such as decompression of a high energy stream. Typically, the compression unit is thereby configured to utilize mechanical energy recovered from a decompression unit positioned downstream of the stripper and upstream of the recovery section.

摘要： Disclosed is a process for the production of methanol from a hydrocarbon feed. Particularly, the process is suitable for a hydrocarbon feed that has not been subjected to the removal of carbon dioxide. The process of the invention comprises the steps of (a) providing a hydrocarbon feed; (b) subjecting the hydrocarbon feed to Catalytic Partial Oxidation (CPO) so as to obtain a synthesis gas mixture; and (c) subjecting the synthesis gas mixture to methanol-forming conditions together with an additional feed of hydrogen (H 2 ), so as to obtain methanol; wherein the hydrocarbon feed is a CO 2 - containing hydrocarbon feed and wherein the Catalytic Partial Oxidation is conducted in the presence of a molar excess of H 2 O, and wherein the additional hydrogen feed is obtained by recovering blowdown gas obtained from the reactor in which the methanol formation takes place and subjecting the recovered gas to pressure swing absorption so as to extract hydrogen therefrom, and wherein gas remaining after hydrogen extraction is recycled as a feed to the Catalytic Partial Oxidation. The process of the invention is particularly suitable for the production of methanol in off-shore circumstances, such as by Floating Production Storage and Offloading (FPSO).

摘要： The present invention presents a stripping process for urea production with a total recycle. An important characteristic of the described urea process is a substantially complete CO 2 conversion, which eliminates the need for carbamate recycle from the recovery section to the synthesis section. This increases the overall conversion and reduces operation costs.
