Claims (8)

1. Способ замедленного коксования, в котором отбираемые из верхней части коксового барабана пары подаются во фракционирующую коксовую колонну, в которой они разделяются на пары, отбираемые из верхней части колонны, промежуточные жидкие фракции и образующийся в зоне мгновенного испарения газойль, в котором содержится значительное количество твердых частиц, отличающийся тем, что образующийся в зоне мгновенного испарения газойль подвергают фильтрации с целью уменьшения количества содержащихся в нем твердых частиц; и отфильтрованный на стадии (а) образовавшийся в зоне мгновенного испарения газойль пропускают через установку для гидроочистки с неподвижным слоем катализатора.1. The method of delayed coking, in which the vapors taken from the top of the coke drum are fed into a fractionating coke column, in which they are divided into vapors taken from the top of the column, intermediate liquid fractions and gas oil formed in the flash zone, which contains a significant amount solid particles, characterized in that the gas oil formed in the flash zone is filtered to reduce the amount of solid particles contained therein; and the gas oil formed in step (a) formed in the flash zone is passed through a hydrotreatment unit with a fixed catalyst bed. 2. Способ замедленного коксования по п. 1, в котором во время фильтрации из газойля удаляют по существу все твердые частицы, размер которых превышает 25 мкм. 2. The delayed coking method according to claim 1, wherein during filtration substantially all solid particles are removed from gas oil, the size of which exceeds 25 microns. 3. Способ замедленного коксования по п. 1, в котором установка для гидроочистки представляет собой установку для гидрокрекинга. 3. The delayed coking method according to claim 1, wherein the hydrotreatment unit is a hydrocracking unit. 4. Способ замедленного коксования по п. 1, в котором установка для гидроочистки представляет собой гидравлический десульфоратор. 4. The delayed coking method according to claim 1, wherein the hydrotreatment unit is a hydraulic desulfurizer. 5. Способ замедленного коксования по п. 4, в котором прошедший через гидравлический десульфоратор образовавшийся в зоне мгновенного испарения газойль подают в установку для крекинга с псевдоожиженным слоем катализатора. 5. The method of delayed coking according to claim 4, in which the gas oil that has passed through the hydraulic desulfurizer and is formed in the flash zone is supplied to the cracking unit with a fluidized bed of the catalyst. 6. Способ замедленного коксования по п. 1, в котором фильтрацию газойля осуществляют путем пропускания его через фильтрующий элемент, состоящий из нескольких собранных друг с другом в пакет подвергнутых травлению металлических дисков. 6. The method of delayed coking according to claim 1, in which the gas oil is filtered by passing it through a filter element consisting of several metal disks assembled with each other in a packet etched. 7. Способ замедленного коксования по п. 6, в котором фильтрующий элемент периодически продувают в обратном направлении. 7. The method of delayed coking according to claim 6, in which the filter element is periodically purged in the opposite direction. 8. Способ замедленного коксования по п. 6, в котором используют несколько фильтрующих элементов, которые последовательно продувают в обратном направлении, так что по крайней мере через один из фильтрующих элементов всегда можно пропустить подлежащий фильтрации образующийся в зоне мгновенного испарения газойль и удалить из него содержащиеся в нем твердые частицы. 8. The method of delayed coking according to claim 6, in which several filter elements are used, which are sequentially blown in the opposite direction, so that at least one of the filter elements can always pass the gas oil formed in the instantaneous evaporation zone and be removed from it solid particles in it.
