Sampler for hydrogenization device of static bed and sampling method of sampler

Abstract

The invention discloses a sampler for a hydrogenization device of a static bed. The sampler is arranged between a front reactor and a back reactor, and comprises a sample collection system, a pressure balancing system and an emergency blow-down system, wherein the sample collection system further comprises a collection tank, a discharging pipeline connected to the front reactor and a feeding pipeline connected to the back reactor; the collection tank is communicated with the front reactor and the back reactor through the discharging pipeline and the feeding pipeline respectively; a liquid material discharging pipeline is communicated onto the collection tank; the pressure balancing system is communicated to the sample collection system, and used for balancing pressures in the reactors or reducing a pressure in the sample collection system; the emergency blow-down system is communicated to the sample collection system, and used for emergency depressurization when pressure in the sampler exceeds the limit. The invention further discloses a sampling method of the sampler.

Description

technical field [0001] The invention relates to a sample collection device, in particular to a liquid sample collection device of a fixed bed device in the field of oil refining and chemical industry and a sampling method thereof. Background technique [0002] In the field of refining and chemical industry, fixed-bed devices are commonly used catalyst evaluation devices, and fixed-bed devices usually contain two or more reactors. The small-scale fixed-bed device in the laboratory is built to simulate an industrial device, and also contains multiple reactors, each of which is filled with different types of catalysts. To evaluate the device on a small device, it is necessary to know the real catalytic activity of the catalysts loaded in different reactors, which requires sampling the products of each reactor separately, while ordinary small fixed bed devices do not have a separate sampling system. A sampling port is installed between the two reactors. During sampling, oil and...
