Description of the invention (summary of the invention) The invention relates to a method for removing high molecular weight and high melting point hydrocarbon vapors from a hydrocarbon gaseous gas stream generated from liquefied solid waste plastic materials, thereby generating a component. Oil that can be used as fuel in the oxidation reaction. The hydrocarbon vapor waste gas stream directly contacts the water spray at a condensation temperature exceeding the melting point of the high molecular weight hydrocarbons contained in the exhaust gas. This allows the high-melting hydrocarbons called "waxes" to condense and be easily removed. 》 After that, one or more condensation steps can be performed at a lower temperature to remove lower-temperature condensable hydrocarbons. The remaining uncondensed vapor is then recovered as a heater fuel for the liquefaction of waste plastic materials. The attached figure is a simplified illustration of the operation of exhaust gas condensation. Description of the preferred embodiment Particulate waste plastic material 'even if it contains halogen, it can be converted from thermal cracking chain to suitable for partial oxidation in quench gasifiers' Responding to the oil composition of the raw materials to produce synthetic gas. The liquefaction of particulate waste plastic materials printed by the consumer cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, especially the block The waste plastic material is directly contacting the waste plastic material with the hot oil melting medium, and a viscous mixture of the waste plastic material is generated in the hot oil melting medium. The melting of the waste plastic material also produces hydrocarbon vapors containing various molecular weights, Exhaust vapor of carbon dioxide and water vapor. Depending on the nature of the waste plastic material, functional acids and halogenated hydrocarbons may also be contained in the exhaust gas vapor. An important feature of the present invention is the liquefaction of particulate waste plastic material The condensed hydrocarbons are recovered by the treatment of the raw waste gas covered by the medium, and the non-condensed hydrocarbon vapors are used as the fuel for the heater for liquefaction of the particulate plastic debris material.

Description of the Invention (The exhaust gas vapor contains a mixture of hydrocarbons of various molecular weights, including high molecular weight hydrocarbons which are known as "waxes". Condensation between about 280 ° F. The exhaust gas vapor also contains condensable low molecular weight hydrocarbons, which will condense at a temperature of about 200 ° F ' At this temperature, hydrocarbons will solidify. Therefore, exposing hydrocarbon-containing exhaust gas generated by liquefaction of waste plastics to temperatures below the melting point of hydrocarbon waxes can produce condensed liquid hydrocarbons and solidify and / or highly viscous hydrocarbons Wax. The solidified wax can cause severe blockage and contamination in the condenser, as well as the closure of the pipelines and equipment of the gasification system. It has been shown that the initial condensation and separation of high molecular weight hydrocarbons in the exhaust vapor at a condensation temperature higher than the melting point of the wax. It can avoid the problems of sealing and blockage in the pipelines and equipment of the gasification system. After the condensable / side lumps are condensed and removed from the exhaust gas, the temperature of the exhaust gas can be further reduced to condense and remove the lower molecular weight condensable hydrocarbons. According to the composition of the exhaust gas, the required number of steps are carried out. The treatment of the exhaust gas includes the removal of water and hydrohalic acid vapor from the exhaust gas, especially the hydrogenated gas (HC1). Therefore, the present invention includes the following steps: Removable condensable hydrocarbons' so high molecular weight 'wax' is steamed from the exhaust gas before the subsequent hydrocarbons condense at lower temperatures to remove lower melting point condensable hydrocarbon vapors It was removed. The present invention can be more easily understood with reference to the figure, wherein the exhaust gas hydrocarbon vapor stream 2 is a by-product of the dissolution of particulate waste plastic materials in a hot oil liquefaction system producing a molten viscous oil mixture and an exhaust gas stream 2. This system directly interacts with spray water 4 contact and cool the exhaust gas stream 2 to a temperature between about 210 ° F and 280T. Water spray cooling of waste gas stream 2 condenses high melting point and high molecular weight hydrocarbon waxes.

Description of the invention (, 4 The temperature is higher than the melting point of the wax, so it will liquefy but will not crystallize or solidify the wax. (Please read the precautions on the back before filling this page) Water spray can be formed Another purpose is to reduce the temperature disturbance of the exhaust gas to produce a mixture of water, uncondensed hydrocarbon vapor and condensed hydrocarbon wax stream 6 and enter the condensate receiver 8 and maintain the temperature from about 210 ° F to 280 ° F. The spray water 4 is preferably supplied by an ammonia-rich stream from an ammonia remover (not shown) used to treat the water used as a scrubbing medium for the synthesis gas from the quench gasifier (not shown). The condensed hydrocarbon wax is separated from the remaining uncondensed exhaust gas vapor and leaves the condensate receiver 8 in the wax stream 10 and enters a second condensate receiver 12 maintained at a temperature between about 60 ° F and 140 ° F. The entity of the first condensate receiver 8 can be located above the second condensate receiver 12, so the condensed liquid hydrocarbon wax stream 10 can flow from the receiver 8 to the receiver 12 by gravity. Ministry of Economic Affairs Printed by Intellectual Property Bureau employee consumer cooperatives is not high An uncondensed vapor stream 14 of a small amount of hydrocarbon wax leaves receiver 8 at a temperature between about 80 ° F and 140 ° F and contains a mixture of hydrocarbons, water, carbon dioxide, and a halogenated acid. When vapor stream 14 passes through As it passes through the heat exchanger 16, the other hydrocarbon vapors condense to form a mixture with the remaining uncondensed vapors and exit with gas stream 18, and then enter a second condensate receiver 12, which is maintained at a temperature between about 60 ° F and 140 ° F. In the second receiver 12, a considerable number of non-fibrous hydrocarbons, and most polar materials such as water, hydrogen, alcohols, ketones, glycols, aldehydes, organic acids, esters, and gas streams 18 Analogs in the like are separated from the remaining uncondensed hydrocarbon vapors and combined with the high molecular weight condensate wax stream 10 to form a combined condensate leaving the condensate receiver 12 as a condensate stream 20. Uncondensed vapor stream 22 Separate from the airflow 18 and pass through the washing tower 24 which can be directly installed above the condensate receiver 12 and leave the condensate receiver 12.

The excess washing solution from the washing column 24 can flow directly to the condensate receiver 12. The uncondensed vapor stream leaving the washing column 24 22 is cooled in the indirect heat exchanger 26 to a temperature of about 40 ° F to 80 ° F. In addition, higher volatility substances condense from the vapor stream 22 to form a condensate stream that mainly contains 4 to 10 carbon organic Compound and water condensate stream 28. The condensate stream 28 leaves the heat exchanger 26 and combines with the condensate stream 20 leaving the condensate receiver 12 to form a combined stream 30. It then enters the pump and periodically discharges the condensate to the reservoir as a chemical raw material or part of the gasification process. The cooled uncondensed hydrocarbon vapor stream 34 leaves the heat exchanger 26 and enters the heat exchanger 36 to be further cooled to a temperature of about 10 ° F to 50 ° F, in which the stream 38 condenses and contains mainly 2-5 carbon atoms. The hydrocarbons and functional hydrocarbons enter the condensate receiver 12. Alternatively, all or part of the stream 38 may be combined with the condensate stream 30 and discharged from the aforementioned pump 32.
