KeyWords: MIP; propylene; catalyst; fullscale first set using Shell gasification technology, large-scale coal to methanol plant put into operation by the end of April 2008, Wing Lung Yu City Coal Group coal chemical 500kt / a coal to methanol plant to produce methanol products stable After testing, the product quality to meet the US Grade AA standards , technical indicators are in control, all safety and environmental protection standards. The device is reportedly the world's first coal gasification technology with Shell's major coal methanol production plant. The project uses a number of energy saving technology, the dry pressurized coal gasification technology with high efficiency, low consumption of coal,[link widoczny dla zalogowanych], raw materials and wide adaptability, \ lower. Other key technologies are selected environmentally friendly, efficient, energy saving and advanced production technology and discharge of slag, ash to achieve full utilization. Gasification of sewage discharge is small and does not contain tar, phenol and other refractory impurities,[link widoczny dla zalogowanych], ammonia, cyanide content and lower, easier to handle. Especially the water used in the production of coal mines for the permanent wastewater discharges. Consumption of coal production year after the project 1.27Mt, value -added per ton of coal increased by 6 times. [China Petrochemical Science and Technology Information Center station of organic feed material] off the liquid hydrogen technology to provide quality in Fushun Petrochemical methyl ethyl ketone methyl ethyl ketone and reducing consumption of hydrogen in Fushun Petrochemical Plant transformation projects off the liquid has passed inspection. The technology not only reduces the loss of methyl ethyl ketone intermediate products to enhance the purity of hydrogen recycling, but also to ensure that the COD (chemical oxygen demand) discharge standards. Off liquid hydrogen technology over the past year, Fushun Petrochemical Plant methyl ethyl ketone were recovered butanol 178.2t, methyl ethyl ketone 29t, eight carbon ketone 32.8t,[link widoczny dla zalogowanych], reduce production costs by 104 million yuan, has not exceeded the discharge occurred c0D accident. Fushun Petrochemical Plant two sets of methyl ethyl ketone,[link widoczny dla zalogowanych], production 55kt / a. Previously, the device with liquid hydrogen by-product of serious, leading to emission of liquid gas cabinet press ketone, alcohol content increases, seriously affecting the COD emission targets, but also lost a lot of effective components of intermediate goods, thereby increasing the device production losses. To solve the problem with liquid hydrogen, in April 2007, Fushun Petrochemical Plant invested 1.1 million yuan, the network of hydrogen recovery unit to transform, and the acquisition of the gas-liquid coalescer and ancillary equipment will be produced by two sets of devices to the coalescence of hydrogen in the pool. Using gas-liquid coalescence technology to butanol, methyl ethyl ketone and carbon and other components of eight ketones isolated from the hydrogen, will be the top gas from the coalescence middle distillates and sent to the hydrogen fuel tank as a high temperature furnace; the solution phase after the distillate from the bottom buffer tank sent to the middle, then hit back to back to the refining plant.
