The present disclosure provides a system and method for recycling intermediate product streams of at least gasoline from the MTP plant to the steam cracker plant for processing with the feedstock of the steam cracker plant to generate a higher percentage of ethylene and propylene. The steam cracker feedstock can be ethane.

Recycling system and process of a methanol-to-propylene and steam cracker plant

The invention relates to a method for the coproduction of methanol and ammonia from natural gas involving the following steps: 1. Natural gas (flow) , steam and oxygen are mixed with one another in a reactor A during which the natural gas is partially oxidized and additionally reformed with the aid of catalysts; 2. The gas mixture removed from reactor A is split into a flow (flow) for synthesizing methanol in a unit E and into another flow (flow) for producing hydrogen; 3. The carbon monoxide present in flow (flow) for producing hydrogen is converted into carbon dioxide inside reactor B with the aid of catalysts and intermediate cooling stages; 4. Remaining impurities such as methane, traces of carbon monoxide and argon are washed out in a cleaning unit D, and hydrogen (flows) is fed to the methanol synthesis in unit E and to the ammonia synthesis in unit F; 5. The methanol synthesis gas (flow) is converted into methanol (flow) with the aid of a catalyst, and the methanol is brought to the required level of purity by distillation; 6. The ammonia synthesis gas,(flow) is compressed in unit F and converted into ammonia (flow) with the aid of a catalyst, and the ammonia is separated from the recovered synthesis gas by partial condensation.

Coproduction of methanol and ammonia from natural gas

The invention relates to a heat-recovery boiler () consisting of a tube bundle heat exchanger () which is incorporated into a pressure vessel () downstream of a gasification device. Displacement bodies () are inserted into pipes which are flowed around by hot process gas. According to said invention, in order to avoid corrosion problems like metal dusting, said displacement bodies () are made of graphite.
