Abstract: The present disclosure provides separation processes for removing heavy organics that are formed in various production processes of HCFO-1233zd(E). Such separation processes allow for the recovery and/or separation of the heavy organics from reactants that are used to form HCFO-1233zd(E), including HF. Such separation or recovery processes may utilize various separation techniques (e.g., decanting, liquid-liquid separation, distillation, and flash distillation) and may also utilize the unique properties of azeotropic or azeotrope-like compositions. Recovery of the heavy organic that is substantially free from HF may allow for their use in subsequent manufacture processes or disposal.

Abstract: Certain aspects of natural gas liquid fractionation plant waste heat conversion to simultaneous power and potable water using Kalina Cycle and modified multi-effect-distillation system can be implemented as a system. The system includes a waste heat recovery heat exchanger network coupled to multiple heat sources of a Natural Gas Liquid (NGL) fractionation plant. The heat exchanger network is configured to transfer at least a portion of heat generated at the multiple heat sources to a first buffer fluid and a second buffer fluid flowed through the first heat exchanger network. The system includes a first sub-system configured to generate power. The first sub-system is thermally coupled to the waste heat recovery heat exchanger. The system includes a second sub-system configured to generate potable water from brackish water. The second sub-system is thermally coupled to the waste heat recovery heat exchanger.

Abstract: Provided is a renewable high efficient desulfurization process using a suspension bed, comprising mixing the desulfurization slurry with a hydrogen sulfide containing gas to obtain a first mixture, and passing the first mixture into a suspension bed reactor from bottom to top, with controlling the first mixture to have a dwell time of 5-60 minutes in the suspension bed reactor to allow they contact and react sufficiently with each other; and subjecting a second mixture obtained from the reaction to gas liquid separation to produce a rich solution and a purified gas, feeding the purified gas into a fixed bed reactor for carrying out a second desulfurization to obtain a second purified gas, subjecting the resulting rich solution to flash evaporation and then reacting with an oxygen-containing gas for carrying out regeneration. The process may reduce the sulfur content in the hydrogen sulfide containing gas from 2.4-140 g/Nm3 to 50 ppm or less by using a suspension bed, and further reduce the sulfur content to less than 10 ppm in conjunction with a fixed bed. The invention achieves high efficient desulfurization by combining the suspension bed with the fixed bed connected in series. The present invention has high regeneration efficiency, and the barren solution may be recycled for being used as the desulfurization slurry, without generating secondary pollution, which is very suitable for industrial promotion.

Abstract: The invention is directed to a urea plant with a high pressure synthesis section and a recovery section. The high pressure synthesis section comprises a reactor, a stripper and a condenser, wherein the reactor operates at a higher pressure than the stripper and the condenser. The plant further includes a compression unit between the condenser and the reactor. The compression unit utilizes mechanical energy recovered from a decompression unit positioned downstream of the stripper and upstream of the recovery section.
