The present technology relates to processes for converting PBWO into light and medium distillate such as usable diesel fuel, the processes generally comprising the steps of: boiling the PBWO to dehydrate the PBWO, heating the PBWO to produce PBWO hydrocarbon vapor, contacting the PBWO hydrocarbon vapor with a catalyst, and cooling the resultant vapor to liquid form through heat exchangers to produce light and medium distillate.

The present invention relates to a system and process for preparing aromatics from syngases, which has advantages of shortened flow process and reduced investment. The process comprises reforming the liquefied gas, separated dry gas with a water steam to produce carbon monoxide and hydrogen, which return, as raw materials, to the aromatization system, so that the problem of by-product utilization is solved, and the syngas unit consumption per ton of aromatic products is reduced. The problem of utilization of a dry gas as a by-product is also solved in the present invention from the perspective of recycling economy, which reduces the water consumption in the process, and conforms to the concept of green chemistry.

The invention relates to a process and a plant for staged separation of concomitants from a raw synthesis gas stream to produce synthesis gas and a sulfur-free naphtha product as a by-product, To remove naphtha compounds and sulfur-containing concomitants, raw synthesis gas is treated with a scrubbing medium in a prescrubbing stage and withdrawn from the prescrubbing stage, and the laden scrubbing medium is mixed with water to bring about a phase separation into a scrubbing medium-water mixture and naphtha, wherein sulfur-containing concomitants are in solution in naphtha. To remove the sulfur-containing concomitants the naphtha is heated to obtain sulfur-free naphtha as a by-product of the gas scrubbing.

A system for crude oil desalting and dehydration includes a separation vessel defining a cavity extending along a central axis having a substantially-vertical orientation. The separation vessel comprises a first distributor configured to distribute a mixture within the cavity of the separation vessel, and a second distributor configured to distribute a wash fluid within the cavity of the separation vessel. The mixture comprises crude oil, water, dissolved salts, free salts, or combinations thereof, and the wash fluid comprises an aqueous fluid. The first distributor is disposed within the cavity below the second distributor, and an interface level controller is configured to detect an interface between an oil phase and an aqueous phase and to maintain the interface within a predetermined range within the cavity.
