Abstract

The invention provides a comprehensive treatment system for wastes generated in a C4 deep processing process and belongs to the technical field of petrochemical industry. The comprehensive treatment system comprises a waste incinerator, an alkylated waste acid processing device, a dry gas processing device and a waste water processing device. The alkylated waste acid processing device is used forseparating waste oil in the waste acid; the dry gas processing device is used for collecting dry gas in an overall plant area and intensively processing the dry gas; and the waste water processing device is used for collecting the waste water in the overall plant area and intensively processing the waste water. By virtue of the waste incinerator, the volatile components in oil-containing waste water, concentrated water, non-condensable gas in the tail gas and the waste oil in the waste acid are together sent into the waste incinerator for incineration, thus various resources in the wastes generated in the C4 deep processing process are effectively recycled; the process of the equipment is simple; the capital construction investment is low; the production cost of a small C3 deep processingenterprise is beneficially lowered; the treatment efficiency of the wastes is improved; and the pressure for environment protection is alleviated.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry, and in particular relates to a comprehensive treatment system for C4 deep processing waste. Background technique [0002] C4 deep processing technology includes dehydration, isomerization, aromatization, alkylation and preparation of MTBE (methyl tert-butyl ether) for C4 liquefied gas. C4 deep processing is mostly attached to large-scale oil refining enterprises, but there are also some enterprises that independently build C4 deep processing systems to obtain greater added value. [0003] The waste generated during C4 deep processing mainly includes oily wastewater generated during C4 dehydration, isomerization and aromatization, waste acid generated during the alkylation process and non-condensable gas generated during the process. In the prior art, the disposal methods for the above-mentioned wastes are: [0004] Oily wastewater: after demulsification, gravity degreasing, air f...
