Heat and hydrogen integration in process for renewable alkylbenzene products

A method for production of a linear alkylbenzene product derived from a natural oil comprising:

• deoxygenating the natural oil to form a paraffin stream comprising paraffins, wherein the natural oil is selected from vegetable oils, and animal fats and triglyceride-containing oils;
• separating the paraffin stream to form a C9 to C14 stream comprising C9 to C14 paraffins and a C14+ stream comprising C14+ paraffins;
• linear selective cracking the C14+ stream in a separate linear selective cracking unit under linear selective cracking conditions in the presence of a linear selective cracking catalyst to form a first stream comprising normal or lightly branched C9 to C14 paraffins and a second stream comprising isoparaffins;
• removing contaminants from the first stream, or the C9 to C14 stream, or both to form a decontaminated stream wherein the contaminates comprise sulfur compounds, or nitrogen compounds, or phosphorous compounds, or aromatics, or oxygenates, or fatty acids, or fatty esters, or combinations thereof;
• dehydrogenating the decontaminated stream in a dehydrogenation unit to provide a dehydrogenated stream comprising mono-olefins, di-olefins, and aromatics and a hydrogen stream comprising hydrogen;
• recycling at least a portion of the hydrogen stream to the linear selective cracking unit;
• selectively hydrogenating the di-olefins in the dehydrogenated stream to form additional mono-olefins, and separating and removing the aromatics from the mono-olefins to form an aromatics stream comprising the aromatics and a mono-olefins stream comprising the mono-olefins;
• alkylating benzene with the mono-olefins in an alkylation unit under alkylation conditions to provide an alkylation effluent comprising alkylbenzenes and benzene;
• isolating the alkylbenzenes to provide the alkylbenzene product derived from the natural oil;
• and
• heating exchanging the paraffin stream, or the C9 to C14 stream, or the C14+ stream, or the first stream, or the second stream, or combinations thereof with the dehydrogenated stream, or the alkylation effluent stream, or both;
• or providing heat from deoxygenating the natural oil to the linear selective cracking unit, or the dehydrogenation unit, or the alkylation unit, or combinations thereof, or both.
