Chlorination process

Claim 2

FIG-01

Claim 3

A PROCESS FOR CHLORINATING A HYDROCARBON MIXTURE CONTAINING A SOFT PARAFFIN WAX AND A HYDROCARBON OIL WHICH COMPRISES IN AN INITIAL STAGE CONTACTING SAID HYDROCARBON MIXTURE WITH A CHLORINE-CONTAINING GAS, PASSING THE RESULTING MIXTURE AT AN ELEVATED PRESSURE THROUGH A REACTION ZONE, PASSING THE RESULTING REACTION PRODUCT MIXTURE TO A DISENGAGING ZONE OPERATED AT AN ELEVATED PRESSURE BUT AT A PRESSURE LOWER THAN IN SAID REACTION ZONE WHEREIN BY-PRODUCT HYDROGEN CHLORIDE AND UNREACTED CHLORINE GASES ARE SEPARATED FROM THE CHLORINATED HYDROCARBON MIXTURE, SEPARATELY RECOVERING SAID GASES AND SAID CHLORINATED HYDROCARBON MIXTURE, AND CONTINUOUSLY PASING SAID CHLORINATED HYDROCARBON MIXTURE BACK TO SAID REACTION ZONE, ALONG WITH ADDITIONAL CHLORINE-CONTAINING GAS OBTAINED FROM THE SUCCEEDING REACTION STAGE, CONTINUING THE SEQUENTIAL OPERATIONS OF REACTION DISENGAGING AND RECYCLING, WITHDRAWING AT LEAST A PORTION OF THE CHLORINATED HYDROCARBON MIXTURE FROM THIS STAGE OF THE PROCESS, PASSING SAID WITHDRAWN CHLORINATED HYDROCARBON MIXTURE TO AT LEAST ONE OTHER SUCCEEDING STAGE CONTAINING A SEPARATE REACTION ZONE AND DISENGAGING ZONE, SAID REACTION ZONE HAVING A PRESSURE GREATER THAN THE PRESSURE IN SAID REACTION ZONE OF THE PRECEDING STAGE AND SAID DISENGAGING ZONE HAVING A PRESSURE NO LESS THAN THE PRESSURE IN THE REACTION ZONE OF THE PRECEDING STAGE AND SAID DISENGAGING ZONE OPERATION OF REACTION, DISENGAGING AND RECYCLING IN THE SUCCEEDING STAGE WHILE PASSING CHLORINATED HYDROCARBON MIXTURE RECOVERED FROM SAID PRECEDING STAGE AND CHLORINE GAS OBTAINED FROM A SUCCEEDING REACTION STAGE INTO SAID STAGE, SUBSTANTIALLY FRESH CHLORINE GAS BEING ADDED TO THE LAST SUCCEEDING STAGE PASSING SAID CHLORINE AND HYDROGEN CHLORIDE GASES RECOVERED FROM THE DISENGAGING ZONE TO THE REACTION ZONE OF THE PRECEDING STAGE, OBTAINING FROM SAID SUCCEEDING STAGE A CHLORINATED HYDROCARBON MIXTURE HAVING A HIGHER CHLORINE CONTENT THAN THE CHLORINATED HYDROCARBON MIXTURE WITHDRAWN FROM THE PRECEDING STAGE, AND RECOVERING FROM THE LAST SUCCEEDING STAGE SAID CHLORINATED HYDROCARBON MIXTURE.

Claim 4

A PROCESS FOR CHLORINATING A HYDROCARBON MIXTURE CONTAINING A SOFT PARAFFIN WAX AND A HYDROCARBON OIL WHICH COMPRISES IN AN INITIAL STAGE CONTACTING SAID HYDROCARBON MIXTURE WITH A CHLORINE-CONTAINING GAS, PASSING THE RESULTING MIXTURE AT AN ELEVATED PRESSURE THROUGH A REACTION ZONE, PASSING THE RESULTING REACTION PRODUCT MIXTURE TO A DISENGAGING ZONE OPERATED AT AN ELEVATED PRESSURE BUT AT A PRESSURE LOWER THAN IN SAID REACTION ZONE WHEREIN BY-PRODUCT HYDROGEN CHLORIDE AND UNREACTED CHLORINE GASES ARE SEPARATED FROM THE CHLORINATED HYDROCARBON MIXTURE, SEPARATELY RECOVERING SAID GASES AND SAID CHLORINATED HYDROCARBON MIXTURE, AND CONTINUOUSLY PASING SAID CHLORINATED HYDROCARBON MIXTURE BACK TO SAID REACTION ZONE, ALONG WITH ADDITIONAL CHLORINE-CONTAINING GAS OBTAINED FROM THE SUCCEEDING REACTION STAGE, CONTINUING THE SEQUENTIAL OPERATIONS OF REACTION DISENGAGING AND RECYCLING, WITHDRAWING AT LEAST A PORTION OF THE CHLORINATED HYDROCARBON MIXTURE FROM THIS STAGE OF THE PROCESS, PASSING SAID WITHDRAWN CHLORINATED HYDROCARBON MIXTURE TO AT LEAST ONE OTHER SUCCEEDING STAGE CONTAINING A SEPARATE REACTION ZONE AND DISENGAGING ZONE, SAID REACTION ZONE HAVING A PRESSURE GREATER THAN THE PRESSURE IN SAID REACTION ZONE OF THE PRECEDING STAGE AND SAID DISENGAGING ZONE HAVING A PRESSURE NO LESS THAN THE PRESSURE IN THE REACTION ZONE OF THE PRECEDING STAGE AND SAID DISENGAGING ZONE OPERATION OF REACTION, DISENGAGING AND RECYCLING IN THE SUCCEEDING STAGE WHILE PASSING CHLORINATED HYDROCARBON MIXTURE RECOVERED FROM SAID PRECEDING STAGE AND CHLORINE GAS OBTAINED FROM A SUCCEEDING REACTION STAGE INTO SAID STAGE, SUBSTANTIALLY FRESH CHLORINE GAS BEING ADDED TO THE LAST SUCCEEDING STAGE PASSING SAID CHLORINE AND HYDROGEN CHLORIDE GASES RECOVERED FROM THE DISENGAGING ZONE TO THE REACTION ZONE OF THE PRECEDING STAGE, OBTAINING FROM SAID SUCCEEDING STAGE A CHLORINATED HYDROCARBON MIXTURE HAVING A HIGHER CHLORINE CONTENT THAN THE CHLORINATED HYDROCARBON MIXTURE WITHDRAWN FROM THE PRECEDING STAGE, AND RECOVERING FROM THE LAST SUCCEEDING STAGE SAID CHLORINATED HYDROCARBON MIXTURE.
