摘要： Provided is a particle drying method and the other configurations, which are capable of sufficiently removing the volatile component and down-regulating the increase of the viscosity of the particles after the removal of the volatile component. There is provided a method for producing heterophasic propylene polymerization material particles, the method including: (1) performing monomer polymerization in the presence of a catalyst including a solid catalyst component so as to obtain a component I; (2) performing monomer polymerization in the presence of the component I so as to obtain the component II, so that particles including a volatile component are produced; and (3) causing the particles to contact with an inert gas-containing stream so as to remove the volatile component from the particles. The method satisfies the following Inequation (1): 19.5 ≤ T 1.12 ·t 0.17 ·(C/100) 0.61 /(d·(0.85·P) 1/3 ) 0.13 ≤ 51.4, where T [°C] is a temperature that the particles have when the particles contact with the inert gas-containing stream, t [h] is a contact time period in which the particles contact with the inert gas-containing stream, d [pm] is a median diameter that the solid catalyst component has at the time of start of step (1), P [g/g] is a mass of the particles per 1 g of the solid catalyst component, and C [mass%] is the content of the component II in the particles.

摘要： An object of the present invention is to provide a method for producing methionine enabling efficient recovery and use of ammonia from a gas generated by concentrating a mother liquor. This production method comprises a recovery step of introducing a gas generated in a mother liquor concentration step into a gas washing tower in which water is recycled and bringing the gas into contact with the water to recover ammonia contained in the gas, and a ratio of flow of the water to flow of the gas introduced into the gas washing tower is 2 or more in terms of mass ratio. The water discharged from the gas washing tower is preferably cooled before introduction into the gas washing tower.
