Embodiment Construction

[0019] The present invention makes full use of the dry gas produced by the secondary processing device of the refinery as raw material, adopts advanced and mature high-efficiency desulfurization, light hydrocarbon steam conversion, low-pressure synthesis (5.5MPa), rectification, and pressure swing adsorption PSA to recover the purge gas Advanced hydrogen process flow, co-production of methanol and hydrogen.

[0020] Its technical solution is: mainly made by the following steps: (1) synthesis gas preparation, including dry gas desulfurization, compression, fine desulfurization, hydrocarbon conversion and waste heat recovery; (2) methanol synthesis, including synthesis gas compression, methanol synthesis, Methanol separation; (3) Methanol rectification consists of three parts. Wherein, the above-mentioned syngas preparation following detailed steps:

[0021] The catalytic dry gas from the catalytic unit and the coking dry gas from the coking unit, after liquid separation and pr...

Abstract

The invention relates to an auxiliary process for oil refinery, in particular to a process of hydrogen production by dry gas and methanol co-production. The technical proposal is that: the methanol is produced by the following procedures of: (1) the preparation of synthetic gas which comprises dry gas desulphurization, compression, fine desulphurization, hydrocarbonsííconversion and waste recovery; (2) the synthesis of the methanol which comprises the compression of the synthetic gas, methanol synthesis and methanol separation; (3) the rectification of the methanol. The invention has the advantages that: the dry gas in the invention is not simply taken as the fuel for heating furnace, but becomes the important chemical raw material, and can create higher economical benefit and social benefit.

Description

1. Technical field: [0001] The invention relates to an auxiliary process of an oil refinery, in particular to a dry gas hydrogen production co-production methanol process. 2. Background technology: [0002] At present, most of the dry gas produced in the production process of catalytic cracking units, delayed coking units and other units in small fuel oil enterprises is used as fuel for heating furnaces, causing a great waste of resources. 3. Contents of the invention: [0003] The purpose of the present invention is to address the above-mentioned defects in the prior art, and to provide a dry gas hydrogen production co-production methanol process, so that the dry gas is no longer simply used as a heating furnace fuel, but becomes an important chemical raw material, which can create a higher economic and social benefits. [0004] Its technical scheme is: mainly made by following steps: [0005] (1) Syngas preparation, including dry gas desulfurization, compression, fine ...
