Normal-pressure continuous quantitative feeding system for alkylating device active agent

Abstract

The invention relates to a normal-pressure continuous quantitative feeding system for an alkylating device active agent, and belongs to the technical field of petrochemical engineering. The system comprises a closed unloader, an active agent buffering and micro-negative-pressure dust removal unit, closed dense-phase conveying equipment, an active agent storing and filtering unit, small automatic feeding, metering and conveying equipment, a temporary storing and dust removal unit, a weighing, metering and anti-bonding unit, a double-helix continuous quantitative feeding unit and an emergency shutdown cutting-off unit. According to the normal-pressure continuous quantitative feeding system for the alkylating device active agent, the problems that the active agent is needed to be accurately added and metered, hydrocarbon gas in a reaction kettle is caked and hung on the wall after being in contact with the active agent, and a pipeline is easily blocked are solved; and the problems of environmental pollution and occupational injury to operators caused by active agent dust leakage during agent loading are fundamentally solved.

Description

technical field [0001] The invention relates to a system for continuous atmospheric pressure quantitative feeding of active agents in alkylation units; the system is mainly used for dust-free airtight unpacking, storage, metering, efficient delivery and delivery of active agents in alkylation units in petrochemical enterprises. Dust removal, continuous quantitative feeding, etc., belong to the technical field of petrochemical industry. Background technique [0002] The alkylation reaction of isobutane and butene is a catalytic reaction process for converting the carbon 4 hydrocarbon component of the catalytic cracking reaction product in the petroleum refining industry into carbon 8 branched chain isooctane (alkylated gasoline). Alkylated gasoline has a high octane number and low Reid vapor pressure (RVP: Reid vapor pressure), and is composed of saturated alkanes without aromatics, olefins and sulfur. For clean alkyl gasoline. [0003] The industrialized alkyl gasoline pro...
