Propylene glycol is produced by a reacting of propylene oxide and water using an acid catalyst by a ratio of propylene oxide: water: methanol is 43.04: 802.8: 71.87 lbmol. Among the many manufacturers are Dow, Lyondell, Sinopec, Shell, BASF, Repsol, Huntsman, and others. This means that at least one or two new plants will need to be constructed every year if the industry is to meet the forecast demand. In this paper, three novel process designs are proposed for integrating shale gas processing with ethylene production. Rm = 0.019698 R = 0.21. Mostly used for MEG production.

The plant has the operating flexibility to produce a range of products depending on the alcohol feedstock and operating variables. 4. The EO is first produced by the oxidation of ethylene in the presence of … There are two main routes for Ethylene Glycol (Monoethyle Glycol/MEG) production: one is the Olefin/EO (Ethylene Oxide) Route starting from either naphtha, ethane or methanol, the licensors include Shell, SD, UCC and etc. This report details a plant that produces 1MM tonnes of 99.96% pure ethylene per year from approximately 2.19MM tonnes of 95% ethanol, along with a thorough economic analysis. Scientific Design's Ethylene Oxide/Ethylene Glycol (EO/EG) technology provides the safest and most efficient means for producing high purity EO and/or fiber-grade monoethylene glycol (MEG). { I�J�������l�OM�z(-|��~j�r�X��]Z�;H�u��H�T-�_W�����i��8p�$�9��]����Ӳ�_������bQ������oę���p�j0�/M}�-�M/����vxYg��й��8^&���a��ҫ ��:��>_�+/n�i�E��%�����T W�sTd�s �O�89-"�,7�d�8��&���%2��D��{����\W�|/��8Y�d�0k3R���lj#Cg&�$L�t�.���Z4��'�����7���Q��d��z_n�����>E�#�EẒir&���;A����Z��I=:&X��[���s���ի�nX���܆j�C�zÙV� �r�d�Z�@[�l�L�\���c0d�xڙ�Ԏ�5C���!9"�9�����ʓ�ǴK�e�ȎhW�D�Xc�U2qCbK�$�_�H���5 ��A�>�I,��g�^�n�e0�v'�y%$�ּ*ث��(xy���q{)�3jla-��Z��|��u����ž*���O ��lP�V�4��B3����8�I[Tt�s�g˄����!����t$�IZ�HoF��TȢ� Ck��C�͙P�"���=+D"���v�Qg�����V,Z��L`�Xn����K�4�P��0.08�s����5��o"�SVZ�1�:���dB�r�C�$��w�숆C�w�aJ�Ҡ��#_Z�#�$=�̈́_�����O-���q��%ﺄ���n��|Ym��j_�?f��øp�a�C��O�6��)kC|Tx(`)>$ks.H��e�4ȟT�A��8�%�]X��?#��&�t�=G������� �'���(�ʙ1�Q�l,��(y�4��*�a���2�5Q The site uses state-of-the-art ethylene glycol process technology. ethylene, oxygen, catalysts, chemicals and utilities, and the costs associated with changing out the EO catalyst, to arrive at the total variable cost of EO/EG production.
